Pacific Gas and Electric Co. is one of eleven utilities participating in the first phase of the US Environmental Protection Agency`s (EPA) Photovoltaic Demand Side Management (PV-DSM) Program coordinated by Ascension Technology Inc. (ATI). An extensive effort was made by PG and E to install the nominal 10-kWac EPA Photovoltaic (PV) system on a customer`s building. Problems arose related to permitting, code compliance, roofing materials, and solar access. As a result, the design was modified slightly and the system was installed on a PG and E-owned building in December 1993. Viability of roof-mounted PV will require that the system installation be fully code compliant, straightforward and routine. This paper identifies issues and suggests solutions regarding the installation of utility-grade PV systems on customer premises.
