Frequently asked questions
Real answers for El Cajon homeowners exploring residential solar.
Do you install solar in National City, CA?+
Yes. National City 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 National City homes?+
Mild bayside climate with good production and moderate cooling loads. That usage pattern is exactly what solar offsets best, so most National City homes with SDG&E bills above roughly $150 a month see a strong return.
What kind of roofs do you work with in National City?+
Compact pre-1970 homes with shingle roofs and older main service panels. We inspect roof condition, framing, and your main electrical panel before finalizing any National City design.
How long does a National City solar project take?+
Most National City 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 National City permits and SDG&E interconnection?+
Yes. We pull the local permits for National City, coordinate inspections, and file the SDG&E interconnection paperwork from start to finish.
Do you add batteries in National City?+
We do, and under NEM 3.0 most National City homeowners get more value from a battery than from extra panels alone. Every design is battery ready even if you add storage later.
