Solar & Battery Installation in San Diego, CA
From our La Jolla office, we serve San Diego County under SDG&E — the utility with some of the highest time-of-use rates in the country, which makes battery storage essential.
What going solar looks like in San Diego
San Diego homes are served by SDG&E, and permits run through City of San Diego. We manage both for you. Under NEM 3.0, the smart play here is solar sized to charge a battery, so you run your home on stored solar during the expensive evening peak instead of buying power at top rates.

Local to San Diego
Solar designed around San Diego
We design and install across San Diego — including La Jolla, Pacific Beach, Point Loma, North Park, Carmel Valley, Rancho Bernardo, Scripps Ranch, and Del Mar Mesa.
Climate & energy use
San Diego's coastal neighborhoods sit under a frequent marine layer that keeps summers mild, while inland communities like Rancho Bernardo and Scripps Ranch see far hotter afternoons and steeper cooling loads, so we size arrays and batteries differently depending on where a home sits. Many inland and canyon-edge neighborhoods also fall within elevated fire-hazard zones, where a battery provides backup during the Public Safety Power Shutoffs SDG&E can call during dry Santa Ana wind events.
Roofs & housing stock
San Diego's housing stock ranges from Spanish and Mission-style homes with clay-tile roofs in older coastal neighborhoods to composition-shingle tract homes inland and flat or low-slope modern builds; tile roofs call for specialized flashing and tile-replacement hooks, which we account for in every layout. Hillside and canyon lots common around Point Loma, La Jolla, and the mesas also mean varied roof planes and shading, so we model production per roof face rather than assuming one uniform pitch.
HOA & design review
Many San Diego communities such as Carmel Valley, Rancho Bernardo, and Scripps Ranch have active HOAs and architectural-review committees, and we prepare and submit those approval packages as part of the install.
