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

Brightbox allows you to store the excess energy that your solar energy system produces during the day so that you can use it when you need it most — such as 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 so you don’t have to pay your electric company for extra power to charge your battery system.

Just like solar panels, the number of Tesla Powerwalls you need will be determined by your unique energy needs and habits — for some consumers, one Tesla Powerwall may be sufficient. Your Solar Advisor will help you evaluate your energy usage to customize a solar energy home battery system that sufficiently backs up your entire home. Request a free quote today.

Sunrun Brightbox offers uninterrupted back-up power for your entire home. 

The amount of available back-up power depends on how much energy your household uses. If your Tesla Powerwall battery is fully charged, it can provide approximately one full day of backup for your entire home. When the sun comes out, your battery will start to charge again.

A Tesla Powerwall installation is a relatively simple process. One Tesla Powerwall itself is about the size of a water heater and easily mounted on a wall by our professional installers — usually inside your garage or outside of your home.

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

Our certified electricians will install and configure your Tesla Powerwall for you. Batteries last anywhere between 10 and 15 years, and manufacturers typically offer a ten-year warranty.

Still, Brightbox is more than just a home battery: It’s a holistic service that includes professional maintenance and monitoring during the life of your agreement. Consumers who own their Tesla Powerwall get Sunrun service for ten years, while consumers with a monthly service agreement or full-amount service contract get free Tesla Powerwall maintenance and replacement for the lifetime of their contract.

You can monitor your Tesla Powerwall’s performance on your mySunrun app. Sunrun also manages the home battery system remotely through the use of proprietary software to make sure it’s running as it should and automatically updates your battery’s settings to save you as much money as possible.

Our monthly and full-amount solar leasing options come with proactive monitoring and maintenance — on us. So if we notice that your Tesla Powerwall or solar panels aren’t working at their full capacity, we’ll send an expert over to fix it so you don’t have to lift a finger.

Cash incentives through Green Mountain Power’s Bring Your Own Device (BYOD) Program are available to Vermonters that purchase a solar battery system with Sunrun. Battery owners could earn up to $10,500 toward their battery purchase if they allow GMP to use electricity from their battery during peak energy times. The incentive amount will depend on your home battery’s capacity, length of discharge and municipality. Learn more.

Another major solar battery incentive for people who purchase a solar system is the federal solar investment tax credit, which covers 26% of the owner’s final cost of the solar system. Starting in 2023, the solar tax credit will step down to 22%. After 2023, the tax credit for home solar ends. We recommend contacting a tax professional to most accurately determine the impact of the federal solar tax credit and local tax credits on your taxes.

You can use a portable generator — however, Sunrun doesn’t offer back-up generators. If you want to install a back-up generator, you can contact a local electrician or solar energy installation company. These experts can recommend a system that will be appropriate for your home.

Please note that Tesla Powerwall cannot be installed in homes that already have a standby generator.

Our rechargeable solar battery systems are designed to keep you on-grid during normal service times while still providing reliable backup when the sun isn’t out or during the event of an outage. This is the most reliable and economical way to use your Brightbox system, and it’s the one most strongly recommended by Sunrun’s service experts.

At this time, Brightbox is only available to new Sunrun consumers. We can’t install rooftop solar panels or Tesla Powerwall if you already have an existing solar installation or if it isn’t offered in your area.
