PVUSA US-2, Kerman, California
The PVUSA US-2 system in Kerman, California is a landmark demonstration of the PV grid support concept developed at Pacific Gas and Electric (PG&E). This concept entails the use of PV
systems for the support of overloaded portions of summer daytime peaking electric utility distribution networks. Following extensive modeling and analyses of the local load patterns and predicted PV system
contribution, a contract to construct a 500 kW ac
grid connected single axis tracking PV plant was awarded to Siemens Solar Industries in April 1992. Construction on the plant began in September 1992, and was completed in March 1993. The Kerman installation
comprises 12,240 M55VJ monocrystalline silicon modules mounted on eight rows of single axis trackers. The 650 kW peak
(DC) array occupies approximately four acres, and is tied into PG&E Kerman feeder # 1104 through a pair of Omnion three phase inverters which convert the DC power of the array into 12.5 kV alternating current. Fact Sheet: PVUSA US-2, Kerman, CA |
