SolarCity, a California company that designs, installs and finances solar power systems is now offering leased solar panels to East Coast Rooftops. SolarCity will expand it services to New York, Massachusetts, New Jersey and Pennsylvania. SolarCity is the nation’s largest solar service provider with more than 1,000 employees and 10,000 projects completed or underway.

“SolarCity will be able to offer solar to many homeowners and businesses in the Northeast at or below the cost they currently pay for electricity,” said Lyndon Rive, CEO of SolarCity, in a statement. “We expect thousands of additional homeowners in the Northeastern states to go solar this year, while local incentives are strong.”

The SolarCity will not sell the solar panels to customers–instead, it offers homeowners to lease panels for a monthly fee and a fixed electricity cost (potentially allowing customers to avoid rising electricity prices over the years). SolarCity will also offer the free repair and monitoring services. In addition to taking over the solar installation space, SolarCity aim is to bring the cost of solar to parity with grid power through economies of scale by 2016.
