Frequently asked questions
Real answers for El Cajon homeowners exploring residential solar.
Do you install solar in Bonita, CA?+
Yes. Bonita is part of our regular South Bay service map, and our crews work there out of our El Cajon office at 270 E Douglas Ave.
Is solar worth it for Bonita homes?+
Warm valley climate sheltered from the coastal marine layer. That usage pattern is exactly what solar offsets best, so most Bonita homes with SDG&E bills above roughly $150 a month see a strong return.
What kind of roofs do you work with in Bonita?+
Ranch-style custom homes with tile and shingle roofs plus barns and outbuildings. We inspect roof condition, framing, and your main electrical panel before finalizing any Bonita design.
How long does a Bonita solar project take?+
Most Bonita 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 Bonita permits and SDG&E interconnection?+
Yes. We pull the local permits for Bonita, coordinate inspections, and file the SDG&E interconnection paperwork from start to finish.
Do you add batteries in Bonita?+
We do, and under NEM 3.0 most Bonita homeowners get more value from a battery than from extra panels alone. Every design is battery ready even if you add storage later.
