With Sunrun’s Solar Storage Service, You’ll Experience More Peace of Mind

More than 2.3 million residents in Colorado were affected by outages from 2008 to 2017.1 Still, with Brightbox, you can create and store your own clean and affordable energy when the sun is out to get outage protection for as little as $0 down.

Sunrun is the country’s leading residential solar and energy storage company.2 We work so you can gain energy freedom and security. See why our made-to-fit home solar and battery storage plans, backed by our industry-leading guarantee, have positioned us as one of the best solar installers in Colorado. Please note that Brightbox solar battery storage is only available with the installation of a new home solar energy system due to tech compatibility.


Back up What You Need

Manufactured by industry leaders known for their quality and innovation legacies, our lithium-ion solar-powered batteries are best-in-class. During an outage, Brighbox with a Tesla Powerwall can back up your entire home, or you can back up just the essentials with an LG Chem solar battery. Brightbox with either battery storage option will work to recharge daily when the sun is out until the grid's restored.


24/7 Monitoring and Maintenance

We do the work, so you don’t have to. All Brightbox monthly plans include 24/7 monitoring and maintenance. In the rare case that your solar panels or battery aren’t running as they’re supposed to, we’ll send an expert over to fix it.

Say Goodbye to Expensive Fossil Fuels

Brightbox doesn’t rely on toxic, expensive, and dangerous fossil fuels like traditional generators. You can forget about the fumes, unpleasant noise, and hassle that come with getting gas or diesel for your generator to keep your home powered. Brightbox can charge for free when the sun is out to give you clean and affordable energy. This way, you can keep your lights on during cloudy days, rainy afternoons, at night, or when the electric grid fails.

Climate Change Continues to Worsen

From wildfires to longer droughts, climate change will continue to affect Colorado as global temperatures rise.3 Straining our nation’s already fragile power grid,4 blackouts could become the new normal for Coloradans across the state. With an average of 245 sunny days per year, Colorado’s solar potential could be the key to a brighter energy future for all, today.5

Frequently Asked Questions

Brightbox is a holistic solar home battery service that can offer you cleaner and more reliable back-up power to have better control over your home energy use and cost.

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

Aside from very rare exceptions, Sunrun’s Brightbox 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.

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—though for some consumers, one battery may be sufficient. Your Solar Advisor will help you evaluate your energy usage to customize a solar energy battery system that sufficiently backs up your entire home. Request a free quote to check if you qualify.

An LG Chem solar battery can back up parts of your home, while a Tesla Powerwall can back up your entire home. There are also differences in software and app functionality.

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 can replenish the battery’s energy storage the following day. Back-up ability will depend on your home's unique electricity usage.

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 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 can 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 can last anywhere between 10 and 15 years, and manufacturers typically offer a ten-year warranty.

Still, Brightbox is more than just a home battery. Consumers who own their Tesla Powerwall or LG Chem solar battery get Sunrun service for ten years, while consumers with a monthly service agreement or full-amount service agreement get free maintenance and replacement for the lifetime of their contract.

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

Our monthly and prepaid solar leasing 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 best solar incentive available for a purchased home solar panel system in Colorado are typically the federal tax credits included in the Inflation Reduction Act, which can be as high as 30% for homes that qualify. We recommend contacting a tax professional to accurately determine the impact this may have on your federall taxes.

There are other major solar incentives in Colorado, such as a property and a state sales tax exemption, as well as local utility company rebates.

What's more, Black Hills Energy, Xcel Energy, and other utilities offer net energy metering (NEM) programs that can let you earn bill credits for the excess solar power you produce and send to the grid. Net metering credits can give you better control over your home energy by offsetting your future electricity bills.

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 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 shining or during the event of an outage. This is the best and most economical way to use your Brightbox system, and it’s the one most strongly recommended by Sunrun’s service experts.

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