When a renewable energy system produces more energy than is needed, what happens to the additional energy?

Three things can happen when there is too much energy:

  • It is possible to store extra energy for later use.
  • It is possible to export the extra energy to the grid.


Keeping excess energy for later use is the most common option. Numerous strategies, such as the utilization of batteries, a thermal storage device, or a flywheel, can be used to do this. There are many benefits to storing excess energy. It makes it possible for the renewable energy system to run even when there isn’t much demand for energy, it might help to bring down the cost of the renewable energy system, and it might help to stabilize the grid. However, storing additional energy can be expensive and take up a lot of room. A different option is to export additional energy to the grid. This can be done by either sending the energy to a nearby grid or a grid that is farther away. Energy surplus has several benefits and can be exported. It can help with grid stabilization, cutting carbon emissions, and lowering the cost of the renewable energy system. However, exporting additional energy can be expensive and take up a lot of room. Another option is to employ surplus energy to run extra buildings or infrastructure. This can be done by either using the energy to power other buildings on the land or by sending it to other structures off-site. The use of excess energy to run other constructions has a number of benefits. It can help with grid stabilization, cutting carbon emissions, and lowering the cost of the renewable energy system. However, using extra energy to power new constructions can be costly and take up a lot of space.

Homeowners Associations may be subject to rules and regulations imposed by Homeowners Associations (HOAs) that impact the look and feel of properties within their territory, including the possible limitations on the setup of solar panels or other forms of renewable energy systems.

The ability of an HOA to hinder the installation of a solar system is contingent on various elements–some regions have laws that limit HOA interference, and some HOAs lack solar guidelines in their covenants, conditions, and restrictions (CC&Rs).

State laws:

Overview of state restrictions Suggestions State laws Most states have enacted laws safeguarding a homeowner’s right to install solar, and these sometimes incorporate clauses that restrict HOA interference. These are known as “solar access laws”.

States that do not have solar access laws might still possess “solar easement policies”, which could offer some protection against HOA interference. Nonetheless, solar easements are usually a voluntary agreement involving the adjacent property owners.

Even in states with solar access laws, the HOA may retain some discretion in regulating the appearance of properties and might be able to mandate panel placement or other requirements. However, these restrictions are generally controlled by specific legal provisions.

Overview of state restrictions:

The following list provides an overview of the legal protection against HOA solar intervention by state, whether the state has solar easement policies, and some additional information about the extent to which HOAs can govern panel placement in protected states.

It’s crucial to contact your state or local jurisdiction for comprehensive information on your area’s policies–this guide should not be treated as explicit legal counsel.

Recommendations:

If you’re contemplating the installation of a solar system and are under the jurisdiction of an HOA, it is crucial to scrutinize pertinent state and local laws and regulations. Further, you should also examine the specific terms of your Homeowners Association’s CC&Rs to understand any potential limitations or prerequisites that might be relevant.

Additionally, it could be beneficial to seek advice from a legal professional or other expert well-versed in solar energy and HOA rules.

Understanding the type of your roof is a crucial step in the solar installation process. Each roof type requires a unique mounting method to secure it from weather conditions, and using inappropriate hardware might result in leaks.

This piece will delve into various roof types and guide you in identifying the specific kind you have on your home.

  • Asphalt Shingle
  • Metal
  • Corrugated Metal
  • Standing Seam Metal
  • Stone-Coated Steel
  • Tile
  • Concrete Tile
  • Clay Tile
  • Slate
  • Flat Roofs
  • Built-Up Roofs (BUR)
  • Modified Bitumen
  • EPDM Rubber
  • Thermoplastic Membrane
  • Spray Foam
  • Rolled Composite
  • Wooden Shake

Asphalt Shingle:

Asphalt shingle roofs are the most prevalent type in the United States, owing to their reliability, affordability, and adaptability to various climates.

Characterized by a variety of colors, these roofs are easily recognizable. They are composed of flexible shingles, each made from a base saturated in asphalt and coated with stone granules. These shingles are overlaid on the roof surface, offering robust waterproofing.

If your roof has layered, thin shingles with a grainy, sandy outer surface, it’s highly probable that you have an asphalt shingle roof.

Metal:

Also known as screw-down metal roofing, corrugated metal roofing encompasses various metals but typically consists of steel, aluminum, or copper sheets formed into a pattern of alternating ridges and valleys (akin to a wavy potato chip). These sheets are arranged on the roof surface with overlapping edges and secured with nails or screws to create a robust covering.

If your metal roof doesn’t feature raised seams (explained below), it’s likely that you have a corrugated metal roof.

These sheets are placed on the roof face, edges overlapping. They are then attached with nails or screws to form a durable covering.

You most likely have a corrugated metal roof if your metal roof does not have raised seams (see below).

Standing seam metal:

Standing seam metal roofing bears a resemblance to corrugated metal roofing but with a significant distinction. Instead of attaching the material directly to the roof surface through drilling or nailing, standing seam metal is installed using clips that are drilled into the roof.

The metal panels are joined through an elevated seam, which locks into the drilled-in clips.

This unique feature enhances the longevity of standing seam roofs, making them outlast many other types, and effectively keeps moisture at bay.

However, the added durability comes with a steeper price tag, positioning standing seam metal roofs among the more costly roof types.

If your roof is metallic with noticeable raised seams and devoid of visible roof penetrations, it’s likely that you’re dealing with a standing seam metal roof.

Stone-Coated Steel:

Stone-coated steel roofing, though less common, comprises metal sheets, shingles, or tiles coated in stone granules, and these are installed according to their shape.

One of the main attractions of stone-coated steel is its aesthetic versatility—it can mimic most tile roof types, and it’s generally durable. However, the coating on the metal can chip and crack if walked upon.

Identifying a stone-coated metal roof can be challenging at first, especially as they can resemble various other types. However, a closer look at each individual tile might help. Standard clay/concrete tiles interlock with each other, while stone-coated steel’s imitation will typically appear as a stamped imprint of multiple roof tiles.

Please note:

Due to its brittle nature, Saule Solar does not currently offer options for stone-coated steel roofing.

Tile:

Tile roofs are quite common, particularly in warm, coastal areas like California and Florida. Concrete and clay are two prevalent types of tile roofs.

Concrete Tile:

Concrete tile is a sturdy roofing option, and concrete tiles come in a variety of styles and colors. Compared to clay tile, concrete tile is less brittle but may be prone to staining and growth of moss or lichen. If your roof tiles are thicker and possess a porous texture, you likely have a concrete tile roof. The rough ends of the tile can also be a giveaway.

Clay Tile:

Clay tiles are usually thinner and smoother than concrete tiles, which makes them more fragile to walk on. However, with proper maintenance, clay tile roofs can last for a hundred years. They don’t absorb as much water as concrete tile, preventing staining and lichen or moss growth. If you spot a smooth, less porous surface, you might be dealing with a clay tile roof.

Please note:

Due to its thin and brittle properties, full installation is not available for clay tile roofs through Saule Solar.

Slate:

Slate tiles, essentially slate rock slabs, have a very low absorption rate and are completely fireproof. Like tile roofs, slate roofs are durable but brittle. They can last for centuries with minimal maintenance. Slate tiles generally resemble rough-hewn rock, and some companies even offer synthetic slate roof tiles.

Please note:

Saule Solar does not offer options for slate roofing.

Flat Roofs:

Flat roofs are more common in arid climates where water drainage isn’t a significant issue. There are many different flat roof material types:

Built-Up Roofs (BUR):

Also known as tar and gravel roofs, built-up roofs are durable due to their dense layer of tar and gravel. However, if leaks occur, pinpointing their source for repair can be challenging. They are not recommended in areas with regular, severe inclement weather. If your flat roof has a dense, built-up gravel surface, you probably have a built-up roof.

Modified Bitumen:

A modified bitumen roof is a 5-layer covering with a final layer similar to a built-up roof but with smaller grains. This roof type is commonly applied with heat or cold to adhere, and its sheet-based installation contributes to a quilted appearance with a texture similar to an asphalt shingle roof.

EPDM Rubber:

EPDM rubber is a single-ply roll-on roof type, usually available in black or white. It is either glued, fastened, or weighted down to attach to the roof. It can sometimes resemble a built-up roof if it’s weighted down with stones, although these stones would usually be much larger.

Thermoplastic Membrane:

Flat roofs made of thermoplastic membrane are typically composed of polyvinyl chloride (PVC) or thermoplastic olefin (TPO). Both of these materials are similar, though PVC tends to last a bit longer. Thermoplastic membrane roofing is attached

There are a few distinct terminologies you need to be familiar with when it comes to electricity. These include kW and kWh. But how do the two differ from one another?

The terms kilowatt (kW) and kilowatt-hour (kWh) refer to power and energy, respectively. In other words, kWh represents the total amount of energy consumed over time, whereas kW indicates the amount of power being utilized at any given moment. For instance, a lightbulb that consumes 100 watts will consume 1 kW of power in an hour. A device that consumes 500 watts will consume 5 kW of power in an hour. On the other hand, if you have a 100-watt light bulb, it will consume 1 kWh of energy in 10 hours. In the event that you own a 500 watts of power, it will use 5 kWh of energy in 10 hours. 

Therefore, kWh is a measure of how much energy has been consumed over a period of time, whereas kW is a measure of how much power is being utilized at any particular time.

 

One of the most promising sources of renewable energy is solar electricity. Although the concept of harnessing the power of the sun has been around for generations, solar power has only lately emerged as an attractive choice for households and companies.

So how does solar energy function and why is it gaining popularity? Sunlight is converted into electricity by solar panels. Small solar cells that are packed with photovoltaic material make up the panels. A current of electricity is produced when sunlight strikes the cells and is absorbed by the material. After that, an inverter transforms this current into usable AC electricity. As opposed to relying on conventional electrification produced by the combustion of fossil fuels, this approach generates sustainable energy by harnessing the power of the sun.

To maximize the potential of your roof’s proportions and to develop an exact representation of your project site, we employ solar design software. Using this software, we can strategically place panels based on irradiance. It is crucial to consider how trees, the roof, and other solar panels could produce shade patches when designing a solar system.

Depending on your location and the resources at your disposal, different solar production tactics may be more or less productive. There is no universally applicable answer to the question of what approach is best for solar production. Installing solar panels in a fixed array can be the ideal choice, for instance, if you live in a sunny area with lots of open space. However, if you live in a more crowded location or your home or place of business is in a shaded area, you might want to think using a solar tracker, which maximizes energy production by tracking the sun throughout the day. The best direction will be south, as this is where the sun is most likely to be directly overhead, with East and West-facing panels typically seeing a reduction of 15-20% when compared to South facing, and North being 30-50% reduction.

Ideally, your solar system would last for more than 25 years. In fact, the warranty guarantees that by year 25 you will be operating at least 84% as efficiently as when you started. In the solar industry, it is generally accepted that if your roof is 25 to 30 years old, you should consider replacing it before installing solar.

 

Are you concerned that installing solar will cause roof leaks? Do not worry; your roof will remain watertight with the proper mounting gear and a 10-year workmanship warranty. When solar panels are installed, a lot of people worry about roof leaks. However, hundreds of holes have already been made in your roof as a result of the shingles and tiles being nailed into the plywood decking. Solar mounting hardware that has been properly installed is just as waterproof as your current roofing material. In fact, it is now even more safe thanks to current technologies. Even though human error is still possible during installation, Saule offers a 10-year workmanship warranty that is double-backed to ensure that your roof won’t leak. Less than 1/1,000 Saule systems have roof leaks. With the right installation hardware and a 10-year workmanship warranty, you can relax knowing that your roof will continue to be dry.

 

It is very easy to assess a property for solar power. You must first ascertain whether your roof is in good shape. Furthermore, you need to have access to a south, east, or west facing roof area. Although they are also an option, north-facing roofs will considerably lower the system’s efficiency. Additionally, you must make sure that the roof plane is unobstructed by trees and receives sunshine throughout the day. You probably qualify for solar if you said yes to each of these inquiries. If you would like a more detailed design, we offer this service for free. All you have to do is send an email to contact@saulesolar.co with the subject “site design request” and your most recent power bill. You can see the ideal panel arrangement for optimum effectiveness and return on investment using our free site design. In order to estimate precise production statistics, the design is constructed utilizing satellite photos, lidar for shading, and historical weather and sun patterns. *Be advised that at this time, we do not offer installation services for Decra or foam/manufactured home roofs.

 

The quick answer is that solar panels can still generate electricity on overcast or snowy days. You must take into account the fact that they will produce less power when sizing your system because of this. Let’s examine solar energy in more detail, including how cloudy and snowy weather may affect it. The amount of sunlight that solar panels get determines how much power they can generate. They are therefore more effective where there is a lot of sunlight. Solar panels can still still provide some power in locations with low sunlight. The amount of sunlight that reaches the panels can be decreased by clouds, but it is not entirely blocked. Snow can cover the solar panels and decrease their effectiveness, although it usually isn’t thick enough to totally block the sun’s rays. On a cloudy day, solar panels will typically generate 80% of their usual output, and on a snowy day, 50%. So, while scaling your system, you must take these reductions into consideration.

Installation

Our installers aren‘t direct employees but rather independent companies we have vetted and partnered with. We put every installation company that applies to receive jobs from us through a vetting process. We ensure that they have the proper licenses, equipment, and level of experience needed to perform a high–quality, safe installation. We have them sign an agreement that outlines all of our service expectations.

Here are just some of the requirements they must meet:

  • Must be a licensed general contractor.
  • Must have or operate under a master electrician license.
  • Must offer and sustain a 10-year workmanship warranty.
  • Must install within 30 days of accepting your job.
  • Must be able to onboard you to the Enphase App.
 

Installers are an excellent option for customers that have challenging projects that require training and experience, live in an area where do–it–yourself installations aren‘t allowed, or simply want to guarantee a quick and easy installation process. Customers may prefer the installer option because they get a double–backed warranty, which means we and the installer agree to be liable for your installation. Also, since we handle all communications with installers, you won‘t have to worry about coordinating or scheduling with them.

At Saule, we work hard to give you the greatest warranties, the lowest pricing, and the possibility to save money on solar. Our staff of experts is committed to providing you with the highest quality service and making sure you get the most out of your solar investment. You may be confident that you are receiving the most value for your money since we are dedicated to giving you the best products and services possible. You can count on a hassle-free experience and the chance to save money when working with us on your solar project.

No Salespeople

We differ from other solar companies in that we don’t use salespeople to attract new clients. Instead, we give you the option to request a free, customized quote from us online. If the price is acceptable to you, you can choose to make a completely refundable deposit. This makes the sales process simpler, more open, and less reliant on drawn-out presentations and pushy sales tactics.

Lowest Prices

The fact that we do not have to pay commissions is the biggest benefit of not hiring salespeople. Salespeople are driven to raise solar costs as much as they can in order to earn a commission that is worthwhile. We can cut our pricing to almost half the national average by doing away with them, saving you thousands of dollars.

Double-Backed Warranty

If you have one of our Saule Partner  Installers install your system, you will receive a double backed workmanship warranty. This  provides an additional layer of protection, as  both Saule and our Partnered Installer  are responsible for the installation of your system.

Quick Pay-Off Time

The benefit of acquiring solar for a low price is that you can anticipate a speedy payback period. Other solar businesses can make you wait up to ten years before seeing a return on your investment. However, most of our clients save enough money over time to pay for their systems in just over five and a half years. Get a quote from us today to learn how much you can save!

At Saule, we occasionally utilize Engineering, Procurement, and Construction (EPC) services. Typically, we take care of the engineering, approvals, and equipment purchase ourselves, leaving our partner to handle the installation. In contrast, our partnered installer handles more of the process with EPCs, including engineering, permits, equipment sourcing, and installation. This model is referred to as “Sales Dealer.”

 

From the time of the deposit to the time of installation, a solar project is typically finished by Saule in 2-4 months. The process could take longer for some people, though, because every project is different because of the jurisdiction, power provider, electrical panel, and system size.

Possible Delays to Your Project

Our process sometimes experiences delays because authorities or electricity providers take longer than usual to approve requests. This may be due to a number of things, including a lack of expertise with solar energy, strict application requirements, or simply the length of time it takes to prepare paperwork and plans. The steps required to connect your solar system to your main electrical panel will be evaluated by our professionals. A main panel upgrade, a main panel derate, or the installation of a subpanel might be necessary in specific circumstances. These engineering adders may cause your project to take longer than expected, especially if we need to work with your government and/or electricity provider.

How Does the Sales Dealer Process Work?

The Sales Dealer model’s contract-signing process is similar to how Saule typically operates. An onboarding specialist will still work with you to complete the design and collect any information from you need to complete the process. The engineering, permitting, procurement, and installation of your system will be completed by our installation partner once a contract is signed. Either our installation partner or Saule’s Customer Success Team will offer updates on your project.

How Does Saule Save Me Money This Way?

Saule can develop quickly thanks to the Sales Dealer model without having to rapidly grow our staff, which helps us keep expenses down. These cost reductions can be passed on to our clients. A local installer who is more familiar with the rules and power companies in the area can also oversee projects using this strategy. This can speed up the installation of your solar system and cut down on processing times, which can increase your savings more quickly.

If you’ve read our article on batteries, you’ll know that because of their high price, we don’t always recommend them. Although household solar battery technology is still in its infancy, prices are anticipated to decline and warranties to get better in the future. This implies that adding a battery to your system later may be more cost-effective. If your initial system was installed through Saule, we can help with this. We are unable to connect to already-built solar systems from other businesses. It’s also crucial to keep in mind that many federal, state, and local solar incentives can only be used once. This indicates that the incentives you received for your initial system may not apply to your battery installation.

 

To choose the ideal location for your panels, our design team consults Aurora Solar, a leading design software engine in the solar sector. Your panel location is determined by a number of factors, and you have the option to offer suggestions.

LIDAR.

LIDAR technology, which creates detailed 3D images of your home and its environs, is made available to us by Aurora Solar. With the use of the software’s roof slope and height data, our designers can then produce roof layouts that are exact to scale. This makes it simple for us to position and reposition panels so that we can determine the best energy offset for you.

Shading

Anything that produces a shadow can cause shading on your roof. For an accurate estimate of the solar exposure on your roof, our designers take into account nearby trees and other houses. When installing solar panels, they give preference to locations with the highest sunlight exposure.

Irradiance

Aurora makes use of irradiance mapping, which calculates how much sunlight your roof receives annually. As different portions of your roof receive more sun than others, our designers carefully put panels where they will be most useful to you.

Orientation

A south-facing roof in the northern hemisphere will get more sunlight throughout the year than a north-facing roof. The sun’s position above the equator is to blame for this. To enhance its effectiveness, we give south-facing rooftops top priority when installing solar panels. Roofs that face east or west are also wise investments because they receive between 70% and 80% TSRF (Total Solar Resource Fraction). Depending on the amount of shadowing and the location, even roofs facing north may have some sun access. In order to achieve a 100% energy offset, we intend to use every square inch of roof area.

Obstructions

Plan your solar panel location to account for any impediments that may be present on your roof. This might refer to skylights, vents, or other anything that might interrupt a continuous array. You can move some of these impediments if necessary so that the panels can be installed. Include this in your specific requests, please.

Fire-Code Setbacks

On your rooftop, Aurora mandates that a specific amount of space be maintained clear in order to ensure compliance with local fire safety rules. We check the local building codes to make sure that these standards are followed. In the event of an emergency, this pathway must stay clear.

Aesthetics and Your Requests

Our designers and onboarding specialists are dedicated to providing you with a system that satisfies both your requirements and desired style. A section for specific requests is included in the first form you submit after checking out.

If you think you’ll need more electricity, have plans to upgrade, need a certain location for a panel, or need anything else related, please let us know.

You might think of your diet when you hear the word “derate.” Derating, however, has a different meaning in the electrical industry. It involves limiting how much power a device can handle. To prevent overheating or damage to the gadget, this is frequently done. Derating is frequently used in the electrical distribution sector. In this context, the phrase refers to the power decrease imposed on a main breaker. To prevent overloads on the electrical system, utilize this breaker. You can lower the breaker’s power handling capacity by derating it. You might decide to downgrade a main breaker for a few reasons. This in turn safeguards the electrical system from harm. To follow safety requirements is one justification. To stop the breaker from overheating is another reason. Finally, to prevent harm to the electrical system, you might derate a breaker.

Example: The 120% Rule

A derating guideline for main circuit breakers is known as the 120% Rule. The recommended practice is predicated on the idea that a breaker will trip when it is 120% overloaded. As breakers are often made to trip at higher levels of overload, this is a conservative assumption. To establish the maximum load that a breaker may safely handle, utilize the 120% Rule. A breaker is at risk of tripping when the load on it is 120% more than the rated load of the breaker.

It’s crucial to keep in mind that a main breaker derate cannot always stop a main panel upgrade. It can, however, help you avoid the added expense and time of a main panel upgrade to bring you speedier solar savings. De-rating your main breaker for solar also requires a full main to reverse.

It’s crucial to keep in mind that, especially if your main panel does not meet current code standards, a main breaker derate may not always be sufficient to stop a main panel upgrade. Furthermore, if you decide to derate your main breaker for solar, there is no way to do it back without completely upgrading your main panel. However, derating your main breaker may enable you to delay a main panel upgrade’s additional cost and time, allowing you to start realizing the benefits of solar savings sooner.

This service through Saule has a base price of $650.

Your solar system will connect directly to your main electrical panel when you install it through Saule.

Your main electrical panel may occasionally need to be upgraded or changed in order for your system to connect securely and supply you with electricity. Approximately 15% of our clients need this service.

The brain of your home’s electrical system is located in your main electrical panel. It is also where your breakers are located and where all of the wiring is connected. A main panel update can be the answer if you’re having electrical issues, or if your house is out-of-date or not up to code. Several advantages can result from upgrading your main panel, including:

-A more efficient electrical system A safer home 
-A more up–to–date look –
-Increased capacity for future growth 
-Peace of mind

How Do I Know If I Need a Main Panel Upgrade?

The answer to whether or not you should upgrade your main panel is a question that many people have, and it can be difficult to tell for sure. The only approach to make certain that there isn’t a one-size-fits-all response to this query is to speak with our technical team.

Reasons a Main Panel Upgrade May Be Required.

Several factors could necessitate the need for a main panel upgrade. The main panel’s inability to meet the demands of the house or company could be one factor. The main panel being out of code could be another factor. A main panel update can be necessary if the current main panel is no longer enough for the needs of the house or company. It might not be safe to operate if the main panel is not up to code, and a main panel upgrade might be necessary.
The electrical current for your main panel will rise as a result of adding solar to your home, and occasionally the suggested system will add enough current to exceed the panel’s rating. Your panel will therefore need to be upgraded in order to manage the increased load. The easiest way to determine whether a main panel upgrade is required is to speak with our technical staff.

Main Panel Upgrade Cost.

For a 200/225A main panel upgrade through Saule, the base price would be $3,250, or $5,500 for a 400A main panel upgrade.

The actual cost can vary, though, and in some circumstances, trenching may be necessary to upgrade the overhead or underground conduit that connects to your electrical panel. Utility companies can also ask you to move your main electrical panel, meter, or both, which would cost more money. You will be given an exact price after our engineers have proven that you require a main panel update and have determined precisely what is required. If you want, you are also free to work with a different contractor; but, doing so might make it more difficult for you to qualify for the 30% Federal Solar Investment Tax Credit for the primary panel update. To obtain complete information in this regard, we always advise getting in touch with a tax expert.

 

A subpanel serves as a connecting point between the main service panel and the electrical circuits further down the line, whereas a main electrical panel is directly connected to the power grid. Subpanels are used in many homes to group circuits together.

To install their system, some solar clients will need to have a subpanel added to their house.

Do I Need to Add a Subpanel?

The technical team at Saule will assess your home’s electrical network (breakers, wiring, and capacity) while creating the designs for your system to establish precisely how your solar system will be connected.

Additionally, they will determine whether or not a subpanel is required. It is more likely that you will need a subpanel if your main electrical panel has little to no available breaker space.

Why Do I Need to Add a Subpanel to Install Solar?

If our engineers find that you require a subpanel, it is most likely because your main panel does not have enough room for breakers.

Specific circuits are controlled by switches, often known as “breakers,” in a main electrical panel. Additionally, it has predetermined locations where these breakers must be wired.

There will need to be breakers to turn on and off the system in the event of a fire or repair when Saule connects your solar system to your main electrical panel. We’ll typically need to add a subpanel if your main electrical panel is completely devoid of breaker spaces.

Some main panels just have one breaker, known as the “main breaker,” which serves as the primary entranceway for energy to enter your home from the grid. In this situation, a subpanel with additional breakers to control particular circuits is frequently already present.

Saule will often add a subpanel between the main panel and any existing subpanels if one is needed. This will guarantee that the subpanel is the appropriate size for the corresponding solar system.

In rare cases, adding a subpanel can help avoid the need for a main panel upgrade.

The base cost for a subpanel addition is $800.

 

Congratulations on finishing our process’ Onboarding phase and signing the contract for your system! It’s time to move on to the process’s back-end phases right now. To get your system operational and producing electricity, it will be necessary to coordinate the work of engineers, governments, power providers, homeowners’ associations, and installers.

Engineering.

Our experts will develop the structural and electrical blueprints for your project using the images and site survey data we have for your home. Prior to installing your system, they will determine whether any further work, such as a subpanel addition or main panel update, is required. If any adders, or more work, are required, we will offer them to you for approval.

Permitting.

Once your ideas are finished, our permitting team will submit them for approval to the appropriate authority. Due to the fact that each authority has its own rules, standards, and processing times, the time required to do this can vary.

Application With Your Utility.

We must follow the utility company’s interconnection application guidelines since your solar system will be adding to the grid’s energy supply. We will also submit an application for any net metering or solar buyback programs that your electricity company may have.

Installation.

We can arrange for the installation of your system and the delivery of your equipment after the necessary permits and your utility company’s interconnection application have been accepted. The interconnection procedure typically takes 1-2 days.

Inspection/PTO (Permission to Operate).

In most places, your system must pass an inspection in order to generate electricity. This is done to ensure that your plans were carried out properly, that everything is securely placed, and that your system complies with all applicable rules. We may obtain the Permission to Operate (PTO) from your energy provider once your system has been approved.

Activation.

The process ends with activating your system and starting to produce energy. In order to assist you in turning on your system and setting up the Enphase App for monitoring, our Activations Team will get in touch with you.

From the time of deposit to the time of final installation, the majority of our solar projects take two to four months to complete. This schedule takes into account engineering, securing permissions, and requesting utility services. Nevertheless, because every solar installation is different, the time frame may change based on how quickly you can give us the information we need and how long it takes your local government and power company to issue the required licenses.

Financing

Ads for “Free Solar! ” and “Solar at NO COST” In the solar sector, phrases like “INSTALLATION WITH NO UPFRONT COST” and “” are increasingly popular. These offers may be found everywhere and around the US, on billboards and from salespeople. Free solar is an enticing promise, but it’s typically too good to be true. These advertisements frequently discuss power purchase agreements or solar leasing (PPAs). These alternatives are not available at Saule; we only sell our systems directly.

How Leases & PPAs Work.

In both a lease and a PPA, the solar supplier owns the equipment, but the monthly payment is determined differently in each case. In a PPA, the homeowner pays a rate that is less than their utility’s rate for the power generated, as opposed to a lease where the homeowner pays a fixed rate for the solar energy produced. As a result, neither choice has a one-time fee, but the monthly payment varies according to the project type selected.

Leases.

Customers have the option of choosing a solar lease, which entails paying a monthly “rent” to utilize the system, as opposed to making loan payments or purchasing a solar system in full.

Power Purchase Agreements.

Customers pay a predetermined amount per kWh for the energy the system generates under a Power Purchase Agreement (PPA). Customers are buying the energy, not the system itself, which is why it is called a “Power Purchase Agreement.” 

Tax Credit Eligibility.

If you choose for a PPA/lease, the solar business will own the equipment and the energy it generates, not you. Because of this, only the owner of the system is eligible for the 30% Federal Solar Tax Credit, which means the solar supplier will get the credit rather than the client. The eligibility for state and municipal incentives may also be impacted by this. We advise checking with a tax expert for further information on incentives. Please see this page from the Office of Energy Efficiency & Renewable Energy’s website for additional information about the Federal Tax Credit.

Multiple Utility Bills & Raised Rates.

You must pay a predetermined price per kWh for solar energy under Power Purchase Agreements (PPAs). When compared to pre-solar utility rates, this rate is often 10–20% lower. For instance, if you were previously paying $0.15 per kWh, a PPA could help you save 1-3 cents per kWh. If you use 10,000 kWh per year, this would equate to a savings of $100 to $300. You will have two utility bills because you will still be responsible for paying your utility company for any electricity you use from the grid. Many PPAs also feature annual increases in the cost per kWh. Due to the fact that the payment amount won’t change month to month, a solar loan payment is a safer choice.

Home Value.

The sum of these problems results in a much poorer total return on investment (ROI). According to research, houses with solar systems installed are worth more than houses without them, although this is not true of leased/PPA systems. In fact, research has shown that properties with leased/PPA systems may potentially be worth less than those without. This is because buyers frequently refuse to take on the existing contract, and the seller could have to pay off the system or have it removed, both of which incur substantial costs and risk causing damage to the house. The ROI for these systems is consequently substantially smaller than it would be if you had bought the system altogether.

Recommendations.

Leases and Power Purchase Agreements are not something that Saule provides or endorses (PPAs). As you own your system and all the energy it generates, we think buying a solar system is the most economical choice. This is consistent with our ROI-focused values. While solar leases and PPAs require payments every month for up to 25 years, purchased solar systems often pay for themselves within 5 to 10 years. Additionally, most solar businesses would advise purchasing the solar system at a price that is probably higher than if you had initially purchased it once the initial PPA or lease arrangement expires. PPAs and leases can also make it harder to maintain your property and limit your ability to claim the 30% Federal Solar Investment Tax Credit. We would suggest financing your project if you place a high focus on minimal upfront costs. In this manner, your system can eventually pay for itself while you continue to control your assets. In addition to accepting any independent financing, Saule collaborates with a few lenders to offer financing solutions without dealer fees or prepayment penalties. However, a lease or PPA might be your only choice if you are not qualified for the 30% Federal Tax Credit, are unable to pay for a system altogether, and/or are having trouble getting financing for the project. In this situation, we advise searching EnergySage for a trusted business. Make sure to carefully study your contract, compare policies, and get several quotations.

Saule has never provided roofing services, so the price of a solar installation has never included the cost of a new roof. Additionally, the IRS recently stated that this kind of claim is not acceptable.

“In general, traditional roofing materials and structural components do not qualify for the credit. However, some solar roofing tiles and solar roofing shingles serve as solar electric collectors while also performing the function of traditional roofing, serving both the functions of solar electric generation and structural support and such items may qualify for the credit. Components such as a roof’s decking or rafters that serve only a roofing or structural function do not qualify for the credit.”

It is crucial to be aware that solar sales agents who propose this are either uninformed or unreliable as the IRS warning makes clear that traditional roofing expenses cannot be recovered under the ITC. It is advisable to speak with a tax expert and have them walk you through the solar installation procedure to ensure you can benefit from the benefits that are offered.

You can read more FAQ’s from the IRS about the investment tax credit here.

 

There are 3 primary options for paying for your solar system with Saule.

1. Cash (ACH or Cashiers Check). Cash payment come in 2 installments. The equipment portion is due before we ship the product (about 75% 3-5 days before install) and the install portion is due the day after install (remaining 25%).

2. Financed through our preferred lender, CECU (Clean Energy Credit Union). CECU is one of the only solar lenders that offers a zero “dealer fee” 5.99% 20 year solar loan. Dealer fees typically range from 15-25% of the total amount, due upfront. It’s one of the least transparent practices in the solar industry and we want no part in it. Please note, we do NOT offer CECU for DIY customers. CECU is not available everywhere.

3. 3rd party lenders. You can often procure your own financing via a local credit union or bank that offers superior rates. Payment installments to Saule are required to match that of cash – equipment portion is due before we ship the product (about 75% 3-5 days before install) and the install portion is due the day after install (remaining 25%).

Equipment

A backup generator is an option to a solar battery. Unfortunately, generators are not offered by Saule. Furthermore, a third party must be used to connect a generator to your system. Since we only utilize Enphase microinverters for our systems, the generator also needs to be compatible with Enphase hardware.

Visit the following online page for more details about Enphase’s generator options: Enphase – Generator Support. Generator Integration with the Enphase Energy System provides a list of standby generators that have been endorsed by Enphase.

 

Solar panels may continue to function even when the power is down thanks to Enphase’s breakthrough new Sunlight Backup technology. Contrast this with the typical solar configuration, which is required by law to shut down during power outages in order to prevent transmitting electricity into the grid and perhaps harming workers. Some consumers may find Sunlight Backup useful, however it does have some limitations. Continue reading to find out more about the tools required, the restrictions of Sunlight Backup, and Saule’s suggestions.

Sunlight Backup Equipment and Cost.

Sunlight Backup requires Enphase IQ8+ microinverters, which are standard, Saule hardware, and an Enphase System Controller 2. During a power outage, these two parts will “isolate” your solar panels from the grid, preventing them from transferring electricity to the grid but allowing them to deliver it to your home instead. The System Controller 2 typically costs roughly $5,000 in total, not including the additional labor for installation.

Limitations.

Sunlight Backup’s capabilities are, however, constrained. Only when the main power is out, and only when the sun is shining, can it power 4–8 outlets. The additional cost of the System Controller 2 further suggests that, despite a possible minor boost in security during a blackout, your system will not provide you with as much financial relief.

Recommendations.

Due to its drawbacks, Saule often does not suggest Sunlight Backup as a standalone feature. The Enphase IQ8+ inverters’ abilities to provide Sunlight Backup, however, also allow them to increase the capacity of batteries. Instead, we advise clients who desire Sunlight Backup to get a 3.36kWh battery (where available). This will provide you all the advantages of Sunlight Backup, enabling you to backup more data and not be reliant on the sun’s visibility while also allowing you to use your panels during outages. Please see the System Use Cases for IQ8 Microinverters document from Enphase to learn more about how IQ8+ inverters can function with a battery.

Although they can be pricey and may not be required for everyone, solar batteries are a terrific addition to a solar system. Solar batteries have gained popularity recently, particularly when the Tesla Powerwall was unveiled. At Saule, we provide Enphase IQ Batteries in increments of 10.08kWh and 3.36kwh (though 3.36kWh batteries may not be available in some areas). The Enphase App may be used to control these batteries, which are made to function with microinverters.

The Enphase System Controller 2, which enables automatic backup in the event of a power outage, is also included with our battery builds. Solar batteries are a fantastic addition to a solar system, but they can be expensive and may not be required for all users.

Battery Downsides.

The main problem with batteries is their cost, which can dramatically increase a solar system’s cost per watt. Less than half the estimated lifespan of a solar system, or 10 years, is the average warranty length for batteries. However, the IQ batteries from Enphase have a 10-year/4,000-cycle warranty and an optional 5-year/2,000-cycle extension. Residential solar batteries are anticipated to grow more affordable and come with stronger guarantees in the future, just like other new technology items.

Battery Upsides.

We are dedicated to giving consumers the highest return on investment possible, and buying batteries occasionally can pay off. This is primarily true in the backup power and time-of-use scenarios. Homes in places where there are frequent or lengthy power outages benefit from backup power since the battery works like a backup generator. Because excess energy can be saved for later use rather than being routed back into the grid, time-of-use is advantageous when power companies charge more for energy used during peak hours or in the evening.

Batteries might be the appropriate choice for you if you fall into one of these groups; otherwise, they might not be as advantageous of an investment.

How to Size Your Battery System.

Although the Enphase Estimator can be helpful if you wish to back up certain appliances or other information, many customers choose to install a 10.08kWh battery. This program computes storage based on your consumption data and considers factors such as how long you want to store up data for, certain appliances, electric vehicles, etc.

Adding Batteries to Existing Systems.

If you have previously installed solar panels without batteries and now want to upgrade your system with battery storage, Saule cannot connect to those systems unless they were set up by us. For new clients with installed systems, we do not provide separate battery installations. It can be challenging, expensive, or even impossible to tie into the existing systems because they aren’t always compatible with the batteries we use. Furthermore, tinkering with your current equipment may void its warranty. We advise you to get in touch with the business that performed the initial installation of your system, a distributor of equipment, and/or a nearby contractor. If we installed the system, we can connect to add a battery.

Solar panels use the energy from the sun to produce direct current (DC) electricity. Since power is often distributed as alternating current (AC) energy, this sort of energy is not commonly employed in households. Solar energy systems employ inverters to convert DC to AC. String inverters and microinverters are the two different types of inverters. At Saule, our systems are powered by microinverters.

String Inverters & Microinverters – How They’re Different.

For our equipment builds, Saule uses microinverters, which are always included in the cost. This is true even though microinverters can be more expensive than string inverters, which were formerly more common. However, we can still provide lower prices than the majority of businesses who sell string inverter systems because to our pricing strategy. The Enphase microinverters we employ also have a 25-year warranty, compared to the 10- to 12-year warranty offered by other string inverters.

What Makes Microinverters More Efficient?

String inverters use a network of connected solar panels to convert electricity, however if one of the panels is shaded or broken, it will reduce the output of the entire string’s other panels. This issue is referred to as the “weakest link” issue. However, this problem can be fixed using microinverters. At the point of production, they separately process the energy from each panel. This implies that the remainder of the system won’t be impacted if one panel is destroyed or shaded. Microinverters may also track individual production, which can be used to spot panels that require cleaning, exposure, or repair. Our Enphase microinverters include the monitoring app from Enphase, which may notify you if your system’s performance decreases at any point.

Panel Optimizers.

Although panel optimizers are similar to microinverters, they still require a string inverter because they don’t actually convert energy like inverters do; rather, they merely control it. The power generated by each panel is first preconditioned by panel optimizers, and then it is sent to the main inverter to complete the transformation. This enables them to separately screen each panel and boost yield for arrays that are only partially shaded (like microinverters work). Panel optimizers’ main drawback is that, although though they are frequently guaranteed for 25 years, the string inverter they feed into is typically only guaranteed for 10 to 12 years.

The Bottom Line.

Enphase microinverters, especially those with a lot of shade, are what we think are best for home solar systems. They offer panel-level production and monitoring and have a 25-year warranty. The only drawback is the price, but that is not a problem given Saule’s affordable prices.

As contrast to rooftop or roof-mounted solar systems, ground-mounted solar systems have panels positioned on various forms of racking that are attached to the ground rather than a building’s roof. There are several different types of ground mount racking, including high-tech (but pricey) systems that follow the path of the sun through the sky.

This service through Saule has a base price of $650.

Solar’s Ground Mount Equipment.

IronRidge XR Ground Mount and comparable racking solutions, which are reasonably affordable, robust, and oriented to capture the best sunlight, are used by Saule.

This kind of racking, which is fixed to concrete but can alternatively be done with helical screws, can accommodate 4 rows of panels that are landscape-oriented.

Ground Mount Applications.

Ground mounts are best used when a roof-mounted system cannot be installed for a variety of reasons, including when a roof is highly shadowed or is not physically capable of supporting solar, because they are more expensive than roof mounts.

However, some customers choose ground-mounted systems instead due to aesthetic considerations or the need for a larger system than what their roof can provide.

Residents of mobile homes who own the land their home is built on frequently use ground mounted solar.

Ground Mount Pricing.

Ground mounted systems are more expensive than rooftop solar systems since more tools and people are needed to install them. A ground-mounted system costs an extra flat $0.75/W from Saule. There will probably be additional costs for trenching and running conduit in addition to this flat fee.

Additionally, Saule doesn’t offer full installs for any ground mounted systems that are smaller than 12 kW DC system size because tiny ground mounted systems can have significant static labor and equipment expenses that impact ROI.

Saule offers EV Charger solutions from Wallbox, ChargePoint and Enel X.

Please inquire about pricing and installation services.

 

Saule only offers monocrystalline black-on-black panels. This is so because monocrystalline panels differ from polycrystalline panels in ways that make the former more appropriate for household usage. It’s critical to be aware of the distinctions between the two varieties of solar panels in order to comprehend why.

Differences Between Monocrystalline and Polycrystalline Panels.

Solar cells, the building blocks of solar panels, are responsible for capturing solar energy and producing an electrical current. The primary material in these cells is silicon, a metalloid. Silicon is used in both polycrystalline and monocrystalline cells, although only one crystal is used in a monocrystalline cell. Contrarily, polycrystalline cells have a bluish color and a multi-crystal structure because they are made of a combination of several crystals. Monocrystalline solar cells typically have an all-black appearance and are darker in color.

Why Does It Matter?

Solar cells consisting of polycrystalline silicon and monocrystalline cells have different structural characteristics, which affects how much energy they can produce. Multiple melted fragments are present in polycrystalline cells, which limits the flow of electrons and reduces electricity output. Contrarily, monocrystalline cells have a pure structure that promotes more electron flow and increases power production. This is comparable to the difference between a glass window consisting of whole pieces of glass and one composed of broken glass fragments; the latter will still let light through, but it will be more refracted and dispersed. When the sun is lower in the sky during the winter or when it is rising or setting, monocrystalline panels perform particularly well, but polycrystalline panels do not.

10.08kWh and 3.36kWh are the two sizes of Enphase Batteries that Saule offers. It is crucial to remember that a single battery is typically insufficient to sustainably power a complete home for an extended period of time. When powering specific circuits, such those in lights, refrigerators, and WiFi routers, batteries are a more effective backup option. Enphase batteries have the excellent feature of being expandable. Your system can accommodate numerous batteries, and you can add more afterwards. While each 10.08kWh battery can deliver 15.9 amps of power, each 3.36kWh battery can only deliver 5.3 amps. A 15-20A breaker is commonly used to connect 10.08kWh batteries.

The Enphase Estimator.

You can use the Enphase Estimator to determine how much storage you require for your particular situation. Here’s how to use it: Type in your zip code or home address along with your typical monthly electric bill. Then, choose “Battery” and modify the backup time you want. A pool pump, air conditioner, or electric vehicle are more options. Once the fields have been modified, choose “Show My System Estimate” to see the Estimator’s suggestion. By choosing “More Configuration,” you can either obtain your system summary or make additional changes. You will then have the opportunity to integrate a wide range of appliances into your system. You can manually add an appliance if you need to backup one that isn’t on the list. Your system overview will update as you add equipment and add more storage as necessary. Let us know when you’ve finished sizing your battery storage system so we can include it in your price!

Saule offers installation services for a range of flat roof materials, including polyurethane foam, thermoplastic membrane, and rolled composite.

Non-Penetrating Ballasted Mounts.

When mounting on flat roofs, Saule chooses non-penetrating equipment whenever practical. As flat roofs are more prone to drainage problems than pitched roofs, this aids in preventing potential leaks and extending the life of the roof. For better output, the panels are typically mounted at an angle, and weights, or “ballast,” hold them in place. To accommodate the ballast and mounting hardware, this approach calls for each row of panels to be placed 18 inches apart, which may not be practical for people with small roof spaces. Due to the additional labor and equipment needed, ballasted mounts for flat roof projects, cost an extra $0.15 per watt.

Tilt/Flush Mounting.

For some types of flat roofs, Saule provides penetrating mount solutions upon request. Many customers who choose this option angle the panels (often southerly) to increase solar exposure all day long. Alternatively, if you want, we can install the panels flush with the roof. Customers with small roof spaces can benefit from this since it requires less space between the panels and enables them to be installed next to one another. Since tilt/flush mounts penetrate the roof, they are more expensive than ballasted mounts because they require additional hardware and sealant. The cost to add tilt or flush mounting to a Saule flat roof system is $0.35 per watt.

One might initially ask why a solar panel with a 350–400W rating would be combined with a 300W microinverter. Although it would seem more effective to match the wattage of the two pieces of equipment, this configuration may seem contradictory. Nevertheless, this is done on purpose. In this article, we’ll discuss why this is the case and how our systems are set up.

Converting DC to AC with Microinverters.

The function of the inverter is to change the direct current (DC) energy generated by solar panels into usable alternating current (AC) energy. Since each panel has its own inverter in microinverter systems, it is possible to compare each panel and microinverter directly based on their ratings.

Inverter Clipping.

A 360W-rated panel will typically output at least 300W of useful power when connected with a 300W-rated microinverter, and in rare circumstances up to 315W. When a 300W–rated microinverter is matched with a 360W–rated solar panel, the panel will usually produce at least 300W of usable power, and in some cases up to 315W. This is due to the fact that solar panels don‘t always produce their full capacity at all times. Their wattage rating is listed for “STC“, or “Standard Test Conditions“, which means they are tested to produce their full capacity in controlled ideal temperature and sunlight conditions. 

However, these perfect test conditions don’t occur very frequently in the real world due to weather and other factors, so most of the time the solar panel will produce at least slightly less energy than it is rated for—roughly 10-15%. Enphase microinverters, on the other hand, must pass these tests while performing at or above their rated capacity because they are tested under considerably more demanding conditions with numerous variables. This indicates that there is less inverter clipping since microinverters are able to exceed their rating by 4-5%.

Planning for Panel Degradation.

Planning for panel deterioration by using inverter clipping can be beneficial. While the performance of solar modules typically declines by 0.5% yearly, that of microinverters does not change over time. This implies that the microinverter will continue to be able to convert the same amount of power when the panel rating declines. For instance, the 300W microinverter will still be able to convert 300W of electricity if a 360W panel degrades by 5% over ten years to a maximum capacity of 342W, having no effect on the system as a whole.

Options & Recommendations.

For panels and microinverters, Saule has determined the perfect ratio. Our system performs better and saves more money from solar energy because to the combination of higher wattage panels and mid-level microinverter ratings. We can offer higher-rated microinverters in some locations, but they are more expensive. The most economical alternative is usually to use our standard equipment. Depending on the region and availability, we often employ Enphase IQ8+ microinverters and a few other panel alternatives (see this link for a full list). Ask your onboarding specialist about your alternatives if you want to replace your microinverters with a higher wattage model (such as the IQ8M or IQ8A).

Critter guards can help protect your solar panels by preventing animals and other pests from destroying or harming them. They are normally installed around the perimeter of your solar panels and are comprised of a durable metal or plastic mesh. There are a few reasons why using critter protectors for your solar panels may be something you want to think about. First of all, they can aid in guarding against animal or pest damage to your solar panels. Second, they may contribute to the cleanliness and debris-free maintenance of your solar panels, which may increase their effectiveness. Thirdly, they can aid in deterring theft from your solar panels. Critter guards are typically not required in areas with moderate climates and little wildlife.

Saule does not include critter guards by default, but we do offer them as an optional add-on. This service is priced at $0.15 per watt.
