Brightbox™: Your Reliable Ally Against Blackouts in Rhode Island

With Brightbox and Tesla Powerwall, you can create and store your own clean, safe and affordable solar power to back up your entire home while staying in control of your electricity use and cost.

The Path to Gain Energy Independence and Security

More than 1.1 million residents in Rhode Island were left without power from 2008 to 2017.1 With Brightbox, Sunrun’s comprehensive energy storage solution, you can power through unexpected blackouts and rate spikes for as little as $0 down.

As the leading residential solar and energy storage company in the U.S.,2 Sunrun works so you can gain energy freedom and security. Our personalized home solar and battery storage plans, backed by our industry-leading guarantee, have positioned us as one of the best solar installers in Rhode Island.

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 Your Entire Home

Manufactured by industry leaders known for their quality and innovation legacies, our lithium-ion solar-powered batteries are best-in-class. With Tesla Powerwall, you can back up your entire home through a blackout, and it will recharge daily when the sun rises until the grid is restored.


Stay Protected During Time-of-Use (TOU) Rates

If you want to cut down on your home energy costs, TOU rates tie you to specific schedules — like when everyone’s cooking dinner or watching TV in the evenings.3,4,5 But with Brightbox, you can use your own stored solar energy to stay powered through expensive times of peak usage while reducing the amount of electricity you buy from your electric company. This gives you more control over electricity bills so you don’t have to worry about the cost of using electricity when you need it most.


24/7 Monitoring and Maintenance

We do the work, so you don’t have to. All Brightbox monthly plans come with 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.

The Cleaner and Safer Alternative to Diesel and Natural Gas

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

Solar Panels and a Home Battery vs. An Aging and Unstable Power System

The U.S. electric grid doesn’t have the necessary strength to meet our increasing electricity demand. As a result, power outages happen more often and last longer across Rhode Island and the whole country.6 While government agencies and utility companies work on updating the grid, you can team up with a Rhode Island solar company like Sunrun to boost your peace of mind.

Frequently Asked Questions

Brightbox is a comprehensive solar battery service that offers you clean, safe and reliable back-up power to have better control over your electricity bills.

Brightbox lets you store the excess energy your home solar panel system creates during the day to use it when you need it most — like in the evening, at night or when the electric grid fails due to extreme weather events or physical damage to the distribution system.

While some battery units allow you to store electricity directly from the grid, with Brightbox, the energy is harnessed entirely from the sun. Meaning it’s 100% clean, renewable and free of charge, so you don’t have to pay your electric company for the extra power to charge your battery.

Brightbox offers Tesla Powerwall batteries in New Mexico, which are industry-leading lithium-ion batteries. Compared to lead-acid batteries, solar batteries that use lithium-ion technology are more efficient and have longer life cycles, making them an excellent option to switch to solar.

Like solar-only systems, the number of Tesla Powerwalls you need is determined by your unique energy needs and habits. For some consumers, one Tesla Powerwall may be sufficient. Our Solar Advisors will help you evaluate your energy usage to customize a home solar battery storage system that sufficiently backs up your entire home.

The installation of our Brightbox with Tesla Powerwall is a relatively simple process. The battery system is about the size of a water heater and is placed on a wall or the ground, usually inside your garage or outside of your home.

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

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 ten-year warranty. But Brightbox is more than a home battery: It’s a holistic service that includes professional maintenance and monitoring for 25 years with select plans.

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

Our monthly and full-amount solar plans come with proactive monitoring and maintenance — on us. So if we notice that your Brightbox or solar panels aren’t functioning 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 and battery storage system in Rhode Island is the federal solar Investment Tax Credit (ITC), which covers 26% of its final cost. The ITC drops to 22% in 2021 and ends in 2022. We recommend contacting a tax professional to accurately determine the impact of the ITC on your federal taxes.

Another major solar incentive is the Rhode Island Renewable Energy Fund (REF) that offers you funding of up to $7,500 to purchase a new home solar system. National Grid customers who are not eligible for REF may get compensation for every kilowatt-hour (kWh) created by their home solar system, thanks to their Renewable Energy Growth (REG) program.

Rhode Island also offers property and state sales tax exemptions to purchase and install a new home solar energy system. Plus, Rhode Island also has a net energy metering (NEM) program to help you earn bill credits for the excess clean energy your solar installation creates. Net metering in Rhode Island is an excellent way to increase your control over your future electricity bills.

You can use a portable back-up generator; however, at Sunrun, we don't offer them. If you’re interested in installing a portable generator, you can contact a local electrician or renewable energy installation company. They can recommend a generator that will work best for your energy needs.

Our Brightbox solar battery systems are designed to keep you on-grid during regular service times while still providing reliable, clean energy to back up your home when the sun isn’t shining or during the event of an outage. This is the most efficient and affordable way to use your Brightbox solar and battery storage system, and the one most strongly recommended by Sunrun’s service experts.

At this time, Brightbox solar battery storage is only available with the installation of a new home solar system. We can’t install new rooftop solar panels or a solar battery if you already have an existing solar power system, or if our solar services aren’t available in your area.
