Keep the Lights On with Brightbox

As a Massachusetts homeowner, you’re no stranger to unpredictable weather and power outages. Over 320,000 homes lost power after last October’s windstorm whipped through Massachusetts, the most since Superstorm Sandy. In fact, there were 106 reported blackouts in 2016 alone. That’s thousands of families without power every three or four days.

The imperfect solution? Emergency generators that eat up gallons of fuel by the day. But it doesn’t have to be this way. Massachusetts is working hard on moving away from harmful fossil fuels and toward solar energy for a cleaner, more resilient community.

We, too, are hard at work creating a brighter future for our kids using clean energy and less fossil fuels. That’s where Brightbox steps in. 

Our BrightboxTM solar battery service is currently only available for new Sunrun customers.

1. Power Through Blackouts with Safe Solar Battery Storage

Your Brightbox battery kicks in during a power outage, keeping your lights on while you stay safely inside and in control. The alternative? Unruly generators that have to be kept outside to avoid carbon monoxide poisoning.

With Sunrun Brigthbox there are no harmful effects, no extra noise, and no gas or diesel. Our lithium-ion battery is charged by your solar panels, and powers on during an outage for up to 10 hours. When the sun comes back out, your panels start recharging again. And if you get sun almost everyday? Your battery has unlimited power potential.

2. Lock In Low Rates With Financing Options

You don’t have to be at the whim of one of the highest electricity rates in the nation. Save with Sunrun today and lock in rates with an upfront investment, monthly payments, or purchase the system outright. You choose—our flexible financial options are designed to offer long-term savings.

3. The Clean Alternative to Diesel or Natural Gas

Our home solar battery service solution is the clean alternative to diesel or natural gas generators. And unlike power generators, Brightbox can save you money all year long. The research is in—power from the sun is the clean way to energize our planet. Lights out in the neighborhood? Not a problem in your Brilliant Home.



Throughout the day, your solar energy system powers your home and keeps your battery charged. Now, if there is an outage in the night, Brightbox can power the things you care about most for up to 10 hours* or until the sun comes up again.


Keep your food cold, your lights on, and enjoy greater peace-of-mind during a power outage with Sunrun Brightbox.
