Every San Diego home connected to SDG&E is now on NEM 3.0 net billing, which pays far less for exported power than the old program did.

Frequently asked questions
Real answers for El Cajon homeowners exploring residential solar.
Do you install solar in San Diego, CA?+
Yes. San Diego is part of our regular City of San Diego service map, and our crews work there out of our El Cajon office at 270 E Douglas Ave.
Is solar worth it for San Diego homes?+
Wide variation by neighborhood, marine layer near the coast in early summer and much hotter conditions in inland communities. That usage pattern is exactly what solar offsets best, so most San Diego homes with SDG&E bills above roughly $150 a month see a strong return.
What kind of roofs do you work with in San Diego?+
Everything from 1920s Craftsman bungalows to modern tile-roof tracts, so electrical and structural review varies by home. We inspect roof condition, framing, and your main electrical panel before finalizing any San Diego design.
How long does a San Diego solar project take?+
Most San Diego projects run 6 to 10 weeks from signed agreement to SDG&E approval and activation. The on-roof work itself is usually one to two days.
Do you handle San Diego permits and SDG&E interconnection?+
Yes. We pull the local permits for San Diego, coordinate inspections, and file the SDG&E interconnection paperwork from start to finish.
Do you add batteries in San Diego?+
We do, and under NEM 3.0 most San Diego homeowners get more value from a battery than from extra panels alone. Every design is battery ready even if you add storage later.
