This company claims to be California's fastest growing solar systems implementation company. It just closed its largest round of fundraising to date with $21 million in new investments.

SolarCity offers a unique community-based solar program designed to increase citywide solar adoptions. By encouraging entire neighborhoods to convert to solar, residents receive guaranteed low price. SolarCity is also donating installations of 1 kW solar demonstration systems at local schools to further build community awareness and understanding of the potential of solar energy.
