Get Clean, Renewable, and Affordable Back-up Power in Texas

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

Brightbox allows you to store the excess energy your solar energy system produces during the day so that you can use it when you need it most: during cloudy days, rainy afternoons, at night, or when the electric grid fails due to an extreme weather event, a rolling blackout, or physical damage to the equipment.

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

The Inflation Reduction Act (IRA) includes a federal tax credit of up to 30% for a home solar system, providing a great incentive for those who qualify.We recommend contacting a tax professional to most accurately determine the impact these credits could have on your taxes.

You can learn more about Texas solar incentives here, or just ask a Solar Advisor during your free virtual consultation.

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

But if you’re still interested in Brightbox, please let us know. We’ll contact you when we expand our services. Know that we’re constantly improving our technology to provide a better customer experience.

Aside from very rare exceptions, Sunrun’s Brightbox battery storage 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.

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 shining 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.

You can use a portable generator. However, Sunrun doesn’t offer back-up generators. If you’re interested in installing 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 a Tesla Powerwall or LG Chem solar battery can’t be installed in homes that already have a standby generator.

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

Having a home solar battery service in Texas will help you power through power outages, lock in low rates with flexible financing options, and get a clean alternative to loud and potentially dangerous diesel generators.

Your system is also covered by our Sunrun Guarantee, so we handle maintenance and repairs at no additional charge.

One Tesla Powerwall stores 13.5 kilowatt-hours (kWh) of usable electricity, which can be used to back up the home for a day. An LG Chem solar battery holds 9.8 kWh, which can be used to back up essential parts of the home from 8 to 12 hours. Rooftop solar panels will replenish the battery’s energy storage the following day. Back-up ability will depend on your unique home's power usage.

You can monitor your solar battery performance on your mySunrun app. Sunrun also manages the battery remotely using proprietary software to make sure it works as it should and automatically updates your battery’s settings to save you as much money as possible.

Our monthly and PPA options 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.

The electrical circuits in your home that power your lights and appliances are all connected to breakers, safely regulating the amount of power that feeds each circuit. Multiple appliances can be powered by one breaker. For instance, one breaker could power your refrigerator and nearby outlets or lighting in your kitchen. While you can’t necessarily target individual appliances, with Brightbox, you can choose which breakers you’d like to back up. What you can back up depends on the current wiring of your home.

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

Our certified electricians will take care of installing and configuring your Tesla Powerwall or LG Chem battery 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. People who own their Tesla Powerwall or LG Chem solar battery get service backed by factory warranties, while those with a monthly service or power purchase agreement (PPA) get free maintenance and replacement for the lifetime of their contract.
