Solar installer and financier SolarCity announced on Thursday that it plans to raise a $750 million fund to invest in installing solar panels on the rooftops of home owners, and $300 million of that fund will come from tech giant Google. While Google has put over $1 billion into clean energy projects over the years, the commitment to the SolarCity fund is Google’s largest to date, and the entire fund will be the largest one ever created for residential solar projects.
The deal shows the momentum behind the booming solar panel industry in the U.S. Solar energy represented over a third of all new electricity in the U.S. in 2014, and that could grow to 40 percent in 2015, which would be a new record. The solar industry is now a major U.S. employer, employing twice as many workers as the coal industry; SolarCity employs more workers in California than the state’s three large utilities combined, said SolarCity CEO Lyndon Rive at the ARPA-E Summit earlier this month.
