Microinverter producer Enphase Energy has completed its 12th solar array with GRID Alternatives, a nonprofit that brings solar technology to communities that would not otherwise have access, on a home in Petaluma, California.

Enphase and GRID Alternatives have been working together since 2010, bringing solar power to low-income families in the San Francisco Bay Area. Enphase has donated employee workdays and over 2,300 microinverters to the program. It is credited as having donated the largest inverter donation and supported around 500kW of solar energy.
