SolarCity will begin offering Tesla Motors-made batteries with its commercial solar systems, Reuters reports.
SolarCity will charge consumers 20 percent less than local utilities.
"The goal is to have a significantly differentiated commercial product," Chief Executive Lyndon Rive told Reuters.
"There is nothing out there that we have seen that can compete against this."
The batteries will be offered in parts of California, Massachusetts and Connecticut.
