How We Evaluate San Diego Solar Companies
We evaluate San Diego solar installers based on NABCEP certification, California CSLB C-10 electrical contractor licensing, SDG&E interconnection experience, NEM 3.0 battery storage optimization, and verified customer reviews.
San Diego has some of the highest residential electricity rates in the US — SDG&E's rates regularly exceed $0.40/kWh during peak TOU hours. Combined with San Diego's excellent solar irradiance (266 sunny days/year) and California's 30% federal ITC, San Diego consistently delivers the shortest solar payback periods in the country.
Under NEM 3.0 (Net Billing Tariff), battery storage is essential for San Diego solar installations. SDG&E's high TOU rates create strong arbitrage incentives — storing solar during the day and discharging during 4–9pm peak hours (when SDG&E rates exceed $0.60/kWh) significantly improves solar economics compared to grid export.

Frequently Asked Questions About Solar in San Diego CA
Why is San Diego one of the best solar markets in the US?
Three factors combine to make San Diego exceptional: (1) SDG&E has some of the highest residential electricity rates in the US — often $0.45–$0.65/kWh during peak TOU hours — making every kWh of self-consumed solar extremely valuable. (2) San Diego averages 266 sunny days per year, providing high annual production. (3) California's 30% federal ITC plus potential SGIP battery rebates reduce upfront cost. Solar payback periods of 5–7 years are achievable in San Diego with proper system design.
What is the average cost of solar panels in San Diego CA?
A typical 7–9 kW residential solar system in San Diego costs between $22,000 and $33,000 before incentives. Adding a Tesla Powerwall or Enphase IQ Battery adds $10,000 to $15,000. After the 30% federal ITC, the net cost of a solar-plus-storage system runs approximately $22,400 to $33,600 — but SDG&E's very high rates enable payback periods of 5–8 years for optimized systems.
How important is battery storage for SDG&E solar under NEM 3.0?
Critical. Under SDG&E's NEM 3.0, solar energy exported to the grid earns only the avoided-cost rate (~$0.05/kWh), while SDG&E charges $0.45–$0.65/kWh for grid electricity during peak TOU hours (4–9pm). A battery system allows you to store excess midday solar and discharge it during peak hours — converting low-value grid exports into high-value self-consumption. Without battery storage, a San Diego NEM 3.0 system may have payback periods of 15+ years. With appropriate storage, 5–8 years.
Does SDG&E offer any solar rebates or incentives?
SDG&E does not offer direct solar rebates. California's primary incentives are: (1) 30% federal Investment Tax Credit, (2) California SGIP battery storage rebates (for qualifying installations), and (3) California property tax exemption for active solar systems. SDG&E's high rates are the primary economic driver — every kWh of self-consumed solar saves you significantly more than in lower-rate markets.
