San Diego Solar Incentives
Solar in San Diego is more affordable than most homeowners expect once you stack the incentives. The 30% federal tax credit, California's SGIP battery rebate, and NEM 3.0 net billing can cover a large share of your system cost and bring typical payback to roughly 6 to 10 years.

The 30% federal solar tax credit (ITC)
The federal Residential Clean Energy Credit returns 30% of your total system cost (solar and battery) as a credit on your federal taxes when you own the system. On a typical $20,000 to $28,000 San Diego installation that is roughly $6,000 to $8,400 back. The credit is set to stay at 30% through 2032 before it steps down, so owning sooner locks in the full amount.
SGIP: California's home battery rebate
The Self-Generation Incentive Program (SGIP) pays a rebate toward home battery storage such as the Tesla Powerwall or Enphase IQ Battery. Every SDG&E customer qualifies for a baseline rebate, and homeowners in a high-fire-threat district or on a medical baseline can qualify for the much larger Equity Resiliency tier. We check your address and utility tier, then handle the SGIP paperwork for you.
NEM 3.0 net billing, and how to beat it
Under NEM 3.0 (net billing), SDG&E credits exported solar at a lower rate than NEM 2.0 did. The fix is storage: bank your midday solar in a battery and use it during expensive evening peak hours instead of exporting it cheaply. Pairing solar with a battery is now the single biggest lever on your San Diego savings.
Rate protection and $0-down financing
Every kilowatt-hour you self-generate is one you do not buy at SDG&E's rising rates, among the highest in the nation. With $0-down financing you can still claim the 30% credit and the SGIP rebate while paying nothing up front, as long as you own the system rather than lease it.
San Diego Solar Incentives FAQ
How much is the federal solar tax credit in 2026?
It is 30% of your total system cost, including battery storage, and stays at 30% through 2032. On a typical $20,000 to $28,000 San Diego system that is about $6,000 to $8,400 credited against your federal taxes when you own the system.
What is SGIP and do I qualify?
SGIP is California's rebate for home battery storage. Every SDG&E customer qualifies for a baseline rebate, and homeowners in high-fire-threat districts or on a medical baseline can qualify for the much larger Equity Resiliency rebate. We confirm your tier before you commit.
Does San Diego still have net metering?
California moved to NEM 3.0 (net billing) in 2023. You still earn credit for exported power, but at a lower rate, so pairing solar with a battery to use your own power in the evening is the best way to maximize value.
Can I combine the tax credit, SGIP, and financing?
Yes. You can claim the 30% federal credit, receive the SGIP battery rebate, and still use $0-down financing, as long as you own the system through a purchase or loan rather than a lease.
