Sunrun, a residential solar company, announced the first completed installation of its Sunrun BrightBox energy storage system in the state. The Tesla battery holds solar power captured during the day so that it can be used at night.The system costs around $40,000, but after state and federal tax credits it’s closer to $20,000, Sunrun officials said. But they encourage residents to just lease the system with no out-of-pocket costs.Sunrun offers the leasing option now at 19 cents per kilowatt-hour, which is roughly 20 percent less than the current rates with Hawaiian Electric Co.
This installation is a first for the Hawaiian Electric Company’s (HECO) new Customer Self-Supply (CSS) Program. HECO helps Hawaii homeowners get the assistance they need to install a rooftop solar system with solar energy battery storage. That means they can enjoy clean, affordable solar energy anytime, at rates below their current power bill. In addition, by partnering with HECO, Sunrun can provide products like the BrightBox system for affordable monthly payments or a prepaid lease with little to no money down!
