TECHNICAL POTENTIAL FOR ROOFTOP PHOTOVOLTAICS IN THE SAN DIEGO REGION

This paper estimates the technical potential for rooftop photovoltaics in San Diego County and describes the methods used to derive the estimates. The commercial estimate was derived using Geographical Information Systems (GIS) to map actual rooftops in the City of San Diego. This estimate for the City of San Diego was used to extrapolate an estimate for the entire County of San Diego. The residential estimate was developed using a simple model that incorporates estimated roof space and housing growth trends.
