We do the work so you don’t have to. Our solar lease and prepaid plans come with round-the-clock monitoring and maintenance. If your solar panels or battery aren’t working at their full capacity, we’ll send an expert over to fix it.


Say Goodbye to Expensive Fossil Fuels

Sunrun’s solar and storage systems don't rely on toxic, expensive, and dangerous fossil fuels like traditional generators. Your solar panels can recharge your home battery when the sun is out to give you safer and more affordable energy. This way, you can keep your lights on during cloudy days, rainy afternoons, or at night.3

Power for a More Reliable Energy Future

The recent devastation of severe storms, flash floods, and rising ocean temperatures have severely affected Hawaii’s communities and environment. As harsher natural disasters become more common for residents in the upcoming years, the state continues to make tremendous efforts to get 100% of its electricity from safer and more resilient energy sources, like solar and wind, by 2045.4

Sunrun’s solar and storage service is here to help you harvest the power of the sun. It’s all part of our mission to ensure families across the islands can get access to clean and renewable energy they can count on.

Frequently Asked Questions

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

Brightbox allows you to store the excess energy that your solar energy system produces during the day so you can use it when you need it most—during a storm, in the evening, or at night.

Aside from very rare exceptions, Sunrun’s Brightbox service includes rooftop solar panels. When the sun is out, Brightbox stores 100% clean, renewable, home-grown solar power directly from the rooftop panels so you can use it when you need it most.

Brightbox offers two solar energy battery options: Tesla Powerwall and LG Chem. Both 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 one of the best energy storage options when going solar. 

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.

Just like home solar systems, the size of your rechargeable solar battery system is determined by your unique energy needs and habits. Certain 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 when selecting the right home battery solution for you.

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

Most residential batteries are installed and configured with baseline settings by your solar installer. Solar batteries can last anywhere between 10 and 15 years, and manufacturers typically offer a 10-year warranty. 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 via desktop or mobile with the mySunrun app. Sunrun also manages the battery remotely using proprietary software to make sure it’s running as it should, and it automatically updates your battery’s settings to save you as much money as possible.

Our monthly lease and prepaid plans come with proactive monitoring and maintenance on us. If we notice that your Brightbox or solar panels aren’t working at their full capacity, we’ll send an expert over to fix it without you lifting a finger.

Hawaii has some great solar incentives in place, which offer even more reasons to go solar in the Aloha State. One of the best incentives is the Renewable Energy Technologies Income Tax Credit. This tax credit can cover 35% or up to $5,000 of the final cost of your home solar system.

The federal government has also introduced additional solar incentives through the Inflation Reduction Act (IRA). The increased incentives could mean a tax credit of up to 30% for those who qualify.

We recommend contacting a tax professional to more accurately determine the impact of the federal solar tax credit and local tax credits on your taxes.

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

Our rechargeable solar battery systems are designed to keep you on-grid during normal service times while still providing reliable backup during a stormy day or at night. 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.

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