2001: California Jail Uses US’s Largest Rooftop Solar Array for Electricity

The Powerlight Corporation installs the US’s largest rooftop solar power system, at the Santa Rita Jail in Dublin, California. It is the fourth largest solar electric system in the world. It reduces the jail’s use of conventionally generated electricity by some 30 percent, and provides energy to the jail via three acres of solar electric or photovoltaic (PV) panels.
