Why El Cajon homeowners go solar
El Cajon's hot inland-valley summers drive high air-conditioning bills, so solar pays off quickly here. With SDG&E rates near $0.47/kWh, among the highest in the nation, every kilowatt you generate yourself is money kept in your pocket. A typical El Cajon home system (6–8 kW) runs about $15,000–$28,000 before the 30% federal tax credit, and pairs naturally with a battery to beat NEM 3.0 export cuts.

El Cajon Solar FAQ
Is solar worth it in El Cajon?
Yes. El Cajon's hot inland-valley summers drive high air-conditioning bills, so solar pays off quickly here, and SDG&E's high rates mean strong savings. Pairing solar with a battery under NEM 3.0 keeps the payback in roughly the 6–10 year range, followed by decades of low-cost power.
How much does solar cost in El Cajon?
Most El Cajon homes need a 6–8 kW system, about $15,000–$28,000 (roughly $2.50–$3.50 per watt) before incentives. The 30% federal tax credit and $0-down financing reduce the net cost significantly.
Do I need a permit for solar in El Cajon?
Yes, residential solar in El Cajon is permitted through the City of El Cajon. We handle the full permit and SDG&E interconnection paperwork for you, so you don't have to.
Should I add a battery in El Cajon?
Under NEM 3.0 a battery is highly recommended. It stores your daytime solar for expensive evening peak hours and keeps your El Cajon home powered during SDG&E outages. California's SGIP rebate can offset much of the cost.
