Day-and-Night Solar Savings with Sunrun BrightBox
BrightBox is about as new to homeowners as the Internet was in 1995. Here are some answers to common questions you might have.
What is BrightBox? BrightBox is a solar energy storage solution for your home that includes a solar system and solar battery. Using Sunrun technology, it manages your solar power, battery power, and utility power to maximize your savings, day and night.
How exactly does BrightBox work?
During the day, your money-saving solar panels power your home while excess electricity is used to charge your solar battery. At night, BrightBox takes the reigns to power your home. Throughout this process, a controller manages the battery, discharging and charging it accordingly to meet your energy demands. Your solar energy system and solar battery maintain a connection to the utility grid.
How is Sunrun bringing solar batteries to Hawaii?
To bring new solar innovations to homeowners, we only partner with the best in the business. That’s why we have chosen to partner with LG Chem, a fellow leader in renewable energy. LG Chem batteries are used by leading brands like Apple and Volvo for everything from cell phones to electric cars. We’re joining forces to help you save even more with solar.
Where will the solar battery be installed on my home?
The LG Chem battery is a wall-mountable and outdoor rated lithium-ion battery that will be installed next to your solar inverter and electric meter.
Is my home a good fit for BrightBox?
Homeowners in Hawaii who have not gone solar yet may be a good fit for solar energy storage with Sunrun. Why Hawaii? With the removal of retail-rate net metering in Hawaii, solar homeowners can no longer sell their excess solar energy to the utility grid at a retail price. Hawaii homeowners can enjoy additional solar savings by storing their solar energy at home instead of selling it to the grid for a below-market rate. In the future, we hope to offer BrightBox solar energy storage to more consumers in areas where we believe we can save homeowners the most money.
Now that you know even more about BrightBox, we hope you’ll join us in creating a planet run by the sun. Start your journey today and see how affordable a cleaner, brighter world powered by the sun can be.
