Why San Marcos homeowners go solar
San Marcos's warm inland valleys and hillside homes get strong sun. 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 San Marcos 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.

San Marcos Solar FAQ
Is solar worth it in San Marcos?
Yes. San Marcos's warm inland valleys and hillside homes get strong sun, 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 San Marcos?
Most San Marcos 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 San Marcos?
Yes, residential solar in San Marcos is permitted through the City of San Marcos. We handle the full permit and SDG&E interconnection paperwork for you, so you don't have to.
Should I add a battery in San Marcos?
Under NEM 3.0 a battery is highly recommended. It stores your daytime solar for expensive evening peak hours and keeps your San Marcos home powered during SDG&E outages. California's SGIP rebate can offset much of the cost.
