San Diego’s one of the nation’s solar boom towns. The boom’s been most robust in northern communities away from the coast.
Data released by San Diego Gas & Electric shows the county’s top rooftop solar meccas are east of Interstate 5 and mostly represent people who own their homes instead of renting. Homeowners further from the coast often have higher energy bills that can make solar panels a more attractive investment. Hotspots include Poway, Scripps Ranch, Rancho Bernardo, Ramona and Lakeside.
The SDG&E data is based on the number of solar net energy metering connections – a state-mandated arrangement that allows solar customers to receive credit for energy their systems produce – per ZIP code.
This map shows net metering applications by ZIP code, plus the estimated kilowatts of power the area’s solar panels could produce.
