Many Californians have been saving money on their utility bills by switching to solar. We understand, with rising energy costs, it is important to maximize your savings. That is why Californians are adding Sunrun’s Brightbox™ to their solar system to save even more. And with Brightbox’s energy storage capabilities, you’ll never be left without power again.

California Cashes in on Solar Storage

Sunrun’s Brightbox™ is a powerful lithium-ion battery made by LG that stores excess energy generated by your home solar system. Your home only uses solar energy while the sun is shining. When the sun sets, your house is powered from the grid and susceptible to rising utility costs. By incorporating Brightbox™ into your solar system, you will store solar power and use it when you need it most. BrightboxTM solar battery service is only available for new Sunrun customers.

3 Ways Brightbox Benefits Californians

  1. Savings
    Energy prices dramatically increase during the hours of the day when you need electricity the most due to Time-of-Use (TOU) rates. Brightbox stores solar energy that you don’t use during the day and powers your home at night when power is most expensive, increasing your solar savings.
  2. Peace of Mind
    Power outages happen all too often in California and no one wants to just sit in the dark. When this kind of event occurs, Brightbox becomes a silent power backup that keep your lights on, your refrigerator running, and your devices charged.
  3. Performance Guarantee
    We guarantee your energy production, rain or shine. With our industry-leading performance guarantee, if your system produces more energy than estimated, we don’t charge your for the extra energy.
