The Cleaner and Safer Alternative to Diesel and Natural Gas

Brightbox doesn’t rely on toxic, expensive and dangerous fossil fuels like traditional generators. You can forget about the dangerous fumes, unpleasant noise and hassle that come with getting gas or diesel for your generator to keep your home powered. Brightbox charges every day with the sun to give you clean, safe and affordable energy even if the electric grid fails.

Leave Fossil Fuels and Outdated Electrical Technology Behind

Pennsylvania is the fourth highest producer of carbon dioxide (CO₂) emissions in the nation.3 When you install Sunrun rooftop solar panels with Brightbox energy storage service, you create and store your own solar energy while helping to build a more resilient energy system that uses clean local power.

70% of the lines and large power transformers of the U.S. are more than 25 years old.4 This outdated electrical infrastructure is making blackouts more frequent and longer-lasting across Pennsylvania and the whole country. While government agencies and electric companies work on updating the grid, you can make the switch to solar with a Pennsylvania solar company like Sunrun to help you secure a brighter energy for you and your family.

Frequently Asked Questions

Brightbox is a comprehensive solar battery service that offers you clean, safe and reliable back-up power to have better control over your home energy use and cost.

Brightbox lets you store the excess energy your home solar panel system creates during the day to use it when you need it most — like in the evening, at night or when the electric grid fails due to extreme weather events or physical damage to the distribution system.

While some battery units allow you to store electricity directly from the grid, with Brightbox, the energy is harnessed entirely from the sun. Meaning it’s 100% clean, renewable and free of charge, so you don’t have to pay your electric company for the extra power to charge your battery.

Like solar-only systems, the number of Tesla Powerwalls you need is determined by your unique energy needs and habits. For some consumers, one Tesla Powerwall may be sufficient. Our Solar Advisors will help you evaluate your energy usage to customize a home solar battery storage system that sufficiently backs up your entire home.

The installation of your Brightbox with Tesla Powerwall is a relatively simple process. The battery system is about the size of a water heater and is placed on a wall or the ground, usually inside your garage or outside of your home.

Through Sunrun’s Brightbox service, your home solar battery will automatically disconnect from the grid in the event of an outage and restore power to your home in a matter of seconds. Your rooftop solar panels will continue to recharge your battery until the grid is up and running again.

Most home batteries are installed and configured with baseline settings by your solar installer. Solar batteries last anywhere between 10 and 15 years, and manufacturers typically offer a ten-year warranty. But Brightbox is more than a home battery: It’s a holistic service that includes professional maintenance and monitoring for 25 years with select plans.

You can monitor your battery’s performance with the mySunrun app. Sunrun also manages the battery remotely using proprietary software to ensure it’s working as it should. It automatically updates your battery’s settings to save you as much money as possible.

Our monthly and full-amount solar plans come with proactive monitoring and maintenance — on us. So if we notice that your Brightbox or solar panels aren’t working at their full capacity, we’ll send an expert over to fix it without you lifting a finger.

The best solar incentive available for a purchased home solar panel and battery storage system in Pennsylvania is the federal solar Investment Tax Credit (ITC), which covers 26% of its final cost. The ITC drops to 22% in 2021 and ends in 2022. We recommend contacting a tax professional to accurately determine the impact of the ITC on your federal taxes.

Pennsylvania also offers Solar Renewable Energy Certificates (SRECs) that compensate you for every kilowatt-hour (kWh) your home solar power system produces.

On top of that, with Pennsylvania Electric Company (PECO), PPL Electric Utilities and other utility companies’ net energy metering (NEM) programs, you can earn bill credits for the excess solar energy you create and send back to the grid. Net metering in Pennsylvania can help you increase your control over electricity bills.

You can use a portable back-up generator; however, at Sunrun, we don't offer them. If you’re interested in installing a portable generator, you can contact a local electrician or renewable energy installation company. They can recommend a generator that will work best for your energy needs.

Our Brightbox solar battery systems are designed to keep you on-grid during regular service times while still providing reliable, clean energy to back up your home when the sun isn’t shining or during the event of an outage. This is the most efficient and affordable way to use your Brightbox solar and battery storage system, and the one most strongly recommended by Sunrun’s service experts.

At this time, Brightbox solar battery storage is only available with the installation of a new home solar system. We can’t install new rooftop solar panels or a solar battery if you already have an existing solar power system, or if our solar services aren’t available in your area.
