Frequently Asked Questions

See the states where Sunrun is currently available and the solar incentives that might be offered where you live. Some of the most common solar incentives include tax credits, property tax exemptions, and rebates. No matter what state you live in, you may be eligible for the Federal Solar Tax Credit (ITC)** if you decide to purchase a home solar energy system. 

You can get a Sunrun monthly plan to lease your solar panels or prepay for your renewable energy through a solar power purchase agreement or PPA plan. As a result, any incentive savings you would receive through tax credits and rebates with a system purchase will be passed to you in the form of a lower solar bill.

You can’t talk about solar panels without talking about silicon. Silicon is a non-metallic element and the second-most abundant material on earth.4 It can also convert sunlight into electricity, and it’s a key component in a solar system (also known as a photovoltaic, or PV system).5

Solar panels, solar cells, or PV cells, are made by slicing crystalline silicon (wafers) that are millimeters thin. These wafers are sandwiched between protective glass, insulation, and a protective back sheet, which make a solar panel. The back sheet helps to regulate the temperature and humidity to optimize the solar panel’s efficiency.6 Multiple solar panels connected together create a solar array, and ultimately, a solar system.

Then there’s the physics of how solar cells work: Electricity is made when electrons move between atoms. The top and bottom of a silicon wafer in the solar cell are treated with small amounts of atoms of extra materials—such as boron, gallium, or phosphorus—so that the top layer has more electrons and the bottom layer has less. When the sun activates the electrons in these oppositely charged layers, the electrons move through a circuit attached to the panels. This flow of electrons through the circuit is what generates the electrical current that ultimately powers a home.7

1. Monocrystalline solar panels: Monocrystalline solar panels have the highest efficiency and power capacity out of all other types of solar panels. Another reason why people choose them is because of how they look. The solar cells within monocrystalline panels are square-shaped and have a single, flat black color, making them the most popular type of solar panels among homeowners.8 Sunrun uses monocrystalline PV modules in all its systems.

2. Polycrystalline solar panels: The manufacturing process of polycrystalline solar panels is less costly than monocrystalline panels, but it also makes them less efficient. Usually, polycrystalline solar panels don’t have the corners cut off of them, so you won’t see the large white spaces on the front of the panel that you see on monocrystalline panels.8

3. Thin-film solar panels: Thin-film solar panels are less costly and easier to install than their counterparts. Still, they aren’t the best option for a home solar installation due to their efficiency, lightweight material, and durability.8

When you consider investing in a solar installation, you might wonder how long home solar panels last. Studies have proven solar panels can last anywhere from 20 to 30 years, or sometimes longer.9 This doesn’t mean the panels on your roof will stop producing electricity after a couple of decades. It just means their energy production will decrease by what solar panel manufacturers consider optimal to meet the average family’s energy needs.

All of our solar equipment is backed by factory warranties. On top of that, our monthly solar lease plan and prepaid solar plan (also known as a solar PPA) come with proactive monitoring and maintenance on us. If we notice that your rooftop panels or solar battery aren’t working at their full capacity, we’ll send an expert over to fix it without you lifting a finger. This benefit sets Sunrun apart from the other solar installers in the country.

After you enter a few details about your home, our Automated Site Modeling tool will analyze hundreds of thousands of variables in home solar system designs to build a high-resolution image of the ideal system for your roof. These factors include your home’s pitch, seasonality, sun exposure, shading, and roof obstacles. This helps Sunrun guarantee you receive maximum benefits from your new home solar system.

Yes. At Sunrun, we’re committed to providing you with the best technology, services, and tools, like Automated Site Modeling and Sunrun’s Product Selector, to make your switch to solar as affordable and straightforward as possible. This allows you to worry less about controlling your electric bills, protecting your home from outages, and reducing your carbon emissions.

Brightbox allows you to store the excess energy your solar energy system produces during the day to use it in the evening, at night, or when the electric grid fails due to an extreme weather event or physical damage to the equipment.

Aside from very rare exceptions, Sunrun’s Brightbox service includes rooftop solar panels. Brightbox stores 100% clean, renewable, home-grown solar power directly from the rooftop panels every time the sun is out, so you can use it when you need it most.

We have an entire team of professionals standing by to help you sell your solar home and transfer your contract, if applicable, to the new owners. Sunrun makes it easy to pass your solar lease or power purchase agreement (PPA) to the new owners. Our Service Transfer Specialists handle everything from educating realtors and potential buyers to working with escrow officers, title agents, home inspectors, as well as anyone else who might need to know about your system and solar lease or PPA agreement.

Once you’re approved for a solar installation, your property will undergo a site assessment, and an expert solar technician will schedule a visit with you to confirm your system design.

After that, our Solar Design Experts will make any necessary adjustments to your design and get your final approval. Once it’s approved, we’ll submit your design to the city for permitting, which can take up to eight weeks. From there, either Sunrun or one of our local certified partners will start your solar installation. We only partner with the top-rated solar installers, so you can rest easy knowing you’ll have the highest quality solar installation available.

When your installation is finished, the city or county will perform a final inspection of your system. Once it’s approved, it’ll be connected to the grid, and we’ll submit your documents to the utility company. After your utility company grants Permission to Operate (PTO), you’ll be all set to start powering your home with the sun.

Rooftop solar panels can get hot, particularly during scorching summer days. If the panels do get hot or overheat, they’ll produce less energy as the temperature rises above their optimal energy production range.

In general, residential solar panels are designed to reach their peak efficiency level at 77 °F (25 °C), but their efficiency will decrease by 0.5% for every degree above this temperature. The actual percentage of lower production varies by the solar panel’s manufacturer and model. Ultimately, you want to aim for an exterior temperature range of 59 to 95 °F (15 to 35 °C). Yet, it’s unrealistic for rooftop solar panels to stay within this range all year, especially in places where temperatures can go past 100 °F (37.8 °C). Fortunately, most solar panels can withstand heat up to 149 °F (65 °C).10

Nonetheless, solar panel overheating can be prevented. Many solar panel manufacturers cover the panels in a material that generally conducts and vents heat away from the glass. In addition, solar panels are usually mounted a few inches above the roof, which allows airflow space to help move heat away from the panels.

Despite the reduction in efficiency from extreme heat, solar energy generation doesn’t stop. The lower electricity production due to scorching weather balances out with the longer days of sunlight throughout the seasons. Although solar panels work best on cold, sunny days, they produce solar power year-round in nearly every location and climate.

Solar panels create energy from sunlight—not the sun’s heat. In fact, solar panels produce electricity more efficiently in cooler conditions. Even in the most frigid weather, solar panels turn sunlight into electricity.

How does this work? Colder temperatures enhance solar energy production efficiency, which increases the amount of electricity produced. Electrons are at rest in cooler climates. When the electrons in solar panels are activated by increasing sunlight, a voltage difference is attained that creates an electric current.

Warmer summer temperatures raise the overall energy levels of electrons in solar panels. This increased energy level decreases the energy differential that can be gained, producing less energy. A higher energy state interferes with solar panel electricity production since some energy transfers into heat instead of electricity. Your home doesn’t need to be in a warm-weather state like Arizona, California, Nevada, or Texas to generate reliable solar power. 

While solar panels need sunlight to create electricity, there are two ways you can benefit from solar power during the nighttime: enroll in a net energy metering (NEM) program (if it’s offered where you live), or add a home battery storage service, like Sunrun’s Brightbox.

1. Net energy metering (NEM): Lower-cost grid energy at night

If NEM is offered in your state and by your utility, you may be eligible to earn credits on your bill for the excess solar energy you produce and send back to your utility company.11 At night, you could use those credits toward drawing electricity from the grid at a lower cost. Net metering can help you save money on your future electricity bills. Visit your utility company’s website for more information.

2. Solar battery storage: Reliable, affordable back-up energy, day and night

A battery storage service like Brightbox lets you store the excess solar power you produce for later use. This stored solar energy can keep your devices and appliances running at night, during outages, cloudy days, or rainy afternoons.

Brightbox offers two lithium-ion solar battery storage options: Tesla Powerwall and LG Chem. Tesla Powerwall can back up your entire home while LG Chem backs up to four circuits inside your home. There are also differences in software and app functionality. 

Request a free, personalized quote to connect with a Sunrun Solar Advisor and determine which Sunrun back-up solution would work best for your home.

 

At this time, Brightbox with a Tesla Powerwall or LG Chem solar battery is only available in the installation of a new Sunrun home solar system due to tech compatibility issues. We can’t install rooftop solar panels or a home battery if you already have an existing solar installation or if Brigtbox’s battery storage service isn’t available in your area.

After you answer a few simple questions about your home’s details, lifestyle, and electricity usage, Sunrun’s Product Selector will let you know if a monthly lease plan, prepaying for your solar energy, financing a system, or purchasing outright—along with back-up power service—is the most cost-effective solution for you and your family.
