Frequently asked questions
Real answers for El Cajon homeowners exploring residential solar.
Do you install solar in El Cajon, CA?+
Yes. El Cajon is part of our regular East County service map, and our crews work there out of our El Cajon office at 270 E Douglas Ave.
Is solar worth it for El Cajon homes?+
The valley floor traps heat, so summer afternoons run well above the coast and air conditioning drives most of the annual bill. That usage pattern is exactly what solar offsets best, so most El Cajon homes with SDG&E bills above roughly $150 a month see a strong return.
What kind of roofs do you work with in El Cajon?+
A mix of 1950s through 1980s comp shingle ranch homes and Spanish tile tracts, most with wide south and west roof planes. We inspect roof condition, framing, and your main electrical panel before finalizing any El Cajon design.
How long does a El Cajon solar project take?+
Most El Cajon 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 El Cajon permits and SDG&E interconnection?+
Yes. We pull the local permits for El Cajon, coordinate inspections, and file the SDG&E interconnection paperwork from start to finish.
Do you add batteries in El Cajon?+
We do, and under NEM 3.0 most El Cajon homeowners get more value from a battery than from extra panels alone. Every design is battery ready even if you add storage later.
