Battery Storage Technology

Energy storage technologies are crucial to a clean energy future. Sunrun’s Brightbox includes a powerful lithium-ion battery made by trusted partners like LG Chem to optimize affordability, efficiency, and durability. When fully charged, your battery can have approximately 8-12 hours of backup power on reserve, storing the solar power your panels have produced so you can use it when you need it most.

4 Ways Brightbox Powers You Forward

  1. Clean Backup Power You Can Count On
    Nature can strike when you least expect it. Take for example, California’s unpredictable wildfires; in 2018 wildfires forced some electric companies to shut down power1 to entire neighborhoods. Stay prepared, don’t be left in the dark, get peace of mind for years to come with Sunrun’s Brightbox home energy storage system. Your home battery will have a constant reserve of power. You’ll also be able to choose which rooms and appliances you want to back up. That means you can keep your food cold, your phones charged, and the lights on during a power outage. When the sun’s back out, Sunrun’s solar panels will recharge your home battery so you can continue to get backup power until the grid is up and running again.
  2. Power in Your Hands
    With Brightbox, your energy needs come first. A seamless online user dashboard gives you control over your power usage. And during a blackout, you decide what stays rooms and appliances stay on. The more you know, the closer we get to putting the power back into your hands.
  3. Peace of Mind
    We do the work so you don’t have to. Our flexible financing options come with 24/7 proactive monitoring and maintenance, on us. So if we notice that your home battery or solar panels aren’t working at their full capacity, we’ll send an expert over to fix it. We’re always standing by to make sure your home battery is in top condition, so you can keep powering on.
  4. Battery Storage and Time of Use
    In California, Time-of-Use (TOU) rates can be tricky. TOU rates are electricity rates in which utilities charge for both how much and when you use energy. That means energy prices dramatically increase during the hours of the day when you need electricity the most. Thankfully, Brightbox has you covered. Brightbox’s smart technology provides power during peak demand times so that you don’t need to rely on grid electricity when rates are highest. By buffering you from unpredictable and confusing utility bills, you don’t have to think twice about your power.

Solar Storage is On The Rise in California

California is committed to clean air and reducing greenhouse gas emissions. To gain independence from natural gas, authorities like the California Public Utilities Commission (CPUC) are requiring California’s biggest utilities to invest in clean energy. In fact, California is so committed that it wants half its power to come from clean energy by 2030.2 But how? The key to reducing our reliance on natural gas and other fossil fuels while maximizing renewable energy is energy storage. That’s why even utilities are increasing their installation of solar battery storage projects.3

Solar Battery Storage that Puts You First

With California’s aging power grid, grid reliability is constantly put under pressure to perform. But as the number of extreme weather events begin to rise, the grid just can’t cut it on its own.4That’s why home batteries are crucial to energy resilience. With our holistic solar storage service, you can tap into California’s cleanest, most brilliant source of energy when it matters most. We’ll be by your side every step of the way.

Power your home your way, day and night, with flexible options to own, finance or lease Sunrun’s Brightbox solar battery storage. In a state as sunny as California, don’t be left in the dark. Get connected with one of our experienced solar advisors. See if you qualify today.

Frequently Asked Questions

There are lots of reasons to go solar with battery storage in California, including a great incentive available to households that purchase home batteries. The Self-Generation Incentive Program (SGIP) incentivizes  PG&E, SCE, SCG or SDG&E-powered households when they install a home solar battery to help defray costs for installing batteries. The incentive value will decrease as more households apply for it, so take advantage of it as soon as you can.

Other California incentives include rebates from your local utility and the 30% federal solar Investment Tax Credit (ITC). Get more information on California solar incentives

For customers with solar leases, Sunrun applies for these rebates and tax credits, and automatically includes the savings in our pricing.

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

However, if you’re still interested in Brightbox please let us know—you’ll be the first to know when we’ve come up with a solution. We’re hard at work on optimizing our technology to provide an even more seamless customer experience.

Yes. Brightbox is part of Sunrun’s holistic solar as a service offering. When you choose to go solar with Sunrun, you can add a Brightbox home battery if it is offered in your market.

Brightbox works in tandem with the grid, and is not designed as an off-grid solution.

For most households, one solar battery is sufficient to power your most important appliances. In the event of a blackout, your Brightbox battery provides approximately 8-12 hours of backup power.

When the sun rises, your solar panels charge your battery so you can continue to back up your home until utility power is restored.

The amount of available backup power depends on what you choose to back up, what time of day and season the power outage happens, and how much energy your household uses. If the battery is fully charged, it can provide approximately 8 to 12 hours of backup. If your battery has been discharging throughout the day, it automatically holds a 20% reserve for a backup emergency, or about 3-4 hours for a blackout when the sun is down. When the sun comes back up, your Brightbox will start to charge again.

Brightbox installation is a relatively simple process. The battery itself is about the size of a water heater and easily mounted on a wall—usually inside your garage or outside of your home. The clearance required for a Brightbox battery and its accompanying components is 6.5’ H x 10’ W.

You can use a portable generator—however, Sunrun doesn’t offer backup generators. If you’re interested in installing a portable generator, you can contact a local electrician or renewable energy installation company. These experts can recommend a system that will be appropriate for your home.

Please note that Brightbox cannot be installed on homes that already have a standby generator.

Having a home solar battery service in California can save money by offsetting high Time-of-Use (TOU) rates and provides clean, reliable backup power during a blackout.

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

You can monitor your Brightbox battery’s performance on your mySunrun app. Sunrun also manages the battery remotely using proprietary software so we keep tabs on your system 24/7 to make sure it’s running as it should, and automatically updates your battery’s settings to save you as much money as possible.

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 plus nearby outlets or lighting in your kitchen. While you can’t necessarily target individual appliances, with Sunrun 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.

Think of it as energy surge pricing. Time-of-Use rates, or TOU rates, are electricity rates in which utilities charge for both how much and when you use energy. Under these rates, energy tends to cost more during peak demand times, such as late afternoon and evening when demand is highest.



Brightbox helps manage TOU rates by optimizing your battery’s charge and discharge behavior to maximize savings. To learn more about TOU rates, click here.

Our expert electricians will take care of installing and configuring your battery for you. Batteries last anywhere between 10 and 15 years, and manufacturers typically offer a 10-year warranty.

Still, Brightbox is more than home batteries; it’s a holistic service that includes professional maintenance and monitoring during the life of your agreement. Customers who own their battery get Sunrun service for 10 years, while customers with a BrightSave Monthly or Prepaid contract get free battery maintenance replacement for the lifetime of their contract - generally 20 or 25 years.

In the event of a power outage, appliances like your refrigerator, electronics chargers for cell phones, laptops, and your TV can be backed up by Brightbox for approximately 8 to 12 hours. When the sun rises again, your solar panels will recharge your Brightbox. The most important rooms and appliances in your home will be powered by your home battery until the grid is up and running again. Learn more about how home solar batteries work.

Brightbox stores the electricity your rooftop solar produces during the day for when you need it most, such as in the evening, at night, or when the electric grid fails.
