Power Through Uncertainty

Take Control of Your Energy

Brightbox can buffer you from increasing energy costs so that you have power when you need it most. While we can’t predict how much or how often utility electric rates will rise or when exactly the power will go out, we can always count on the sun rising each day. Take charge of your electric bill and get control of your energy needs now and in the future.

Power Through Unreliable Energy Grids

The benefits of solar-powered batteries go beyond your home. Brightbox’s solar battery service enables you to consume more of the clean energy your solar panels produce, so you rely less on dirty and damaging fossil fuels while you decrease your carbon footprint. A cleaner and safer future starts today — and you can help create it by building a smarter energy grid.

Reliable energy when you need it most.

Uncertainty is uncomfortable. But for those who are already facing the impacts of extreme weather, it's a way of life. It's time to plan for the very real possibility of losing power when you need it most.

Frequently Asked Questions

Brightbox offers two lithium-ion solar battery storage options: Tesla Powerwall and LG Chem. Compared to lead acid batteries, solar batteries using lithium ion technology are more efficient and have longer lifespans. This makes them one of the best energy storage options when going solar. 

Tesla Powerwall can provide whole home backup while LG Chem backs up to four circuits.. There are also differences in the software and app functionality.

One of the best solar storage incentives is the Federal Solar Tax Credit. The Federal Solar Tax Credit will deduct 26% of the cost of your solar energy system from your federal taxes. Starting in 2021, the value of the tax credit will step down to 22%. After 2021, the tax credit for residential solar ends.

Another option is to finance Brightbox with a lease. We’ll pass down the savings to you in the form of a lower and more predictable electric bill. 

Net metering, which credits any excess power your solar system generates back to your electric bill, is another great incentive for many people that go solar. However, several states have chosen to adopt Time-of-Use (TOU) rates, which complicate the way your net metering credits are calculated. Brightbox can buffer you from peak TOU rates so you may save even more on your electric bill.

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 the one most strongly recommended by Sunrun’s service experts.

Just like solar-only systems, the size of your rechargeable solar battery system is determined by your unique energy needs and habits. Factors such as the amount of electricity you use at home and the devices and appliances you want to back up will play a key role as you select the right battery storage solution for you.

Aside from very rare exceptions, Sunrun’s Brightbox service includes rooftop solar panels.

The installation of Brightbox is a relatively simple process. It’s about the size of a water heater, and the system is mounted on a wall — usually inside your garage or outside of your home.

While Brightbox requires an Internet or cellular connection to monitor your energy storage and usage efficiently, it can still operate without it. If for some reason Brightbox happens to go offline, you can resume your usage tracking when your internet connection is back to normal.

Most residential 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 10-year warranty.

Brightbox allows you to store the electricity your solar energy system produces during the day and use it when you need it most — such as in the evening during time of use (TOU) peak pricing or when the electric grid fails due to an extreme weather event or physical damage to the equipment.

Brightbox is a holistic solar battery storage service that offers you clean, safe, reliable backup power to have better control over your home energy use and cost.

Brightbox solar battery storage systems can help you save money on utility bills, protect your home from power outages and reduce your carbon footprint by supporting the production of clean, renewable energy.
