Commercial solar in California (2026)

In California, the average commercial electricity rate is about 25.39¢/kWh — above the U.S. average of roughly 17.6¢. Because a solar system's payback is driven mostly by the utility rate it offsets, California's high rates make business solar a strong bet in 2026.

California uses net billing — exports are credited below the retail rate. That lengthens payback versus full net metering and makes pairing solar with a battery (to use more of your own production) materially more attractive.

Businesses use the Section 48E commercial credit (≈30%, up to ~50% with adders) plus first-year bonus depreciation — together typically recovering ~45–55% of project cost. Construction-start timing matters; verify before acting.

For a typical California business spending about $1,500/month on electricity, our model estimates a 50.64 kW system costing roughly $73,441 after incentives, paying back in about 4.1 years, with on the order of $376,571 in 25-year savings. These are estimates built from California's real electricity rate — get a quote to confirm your numbers.

Businesses in California should weigh construction-start timing for the commercial credit and confirm whether the project qualifies for the domestic-content or energy-community adders, which can lift the credit toward 50%.

California's NEM 3.0 net-billing rules mean a battery is now almost essential for solar to pencil out — design around self-consumption, not export.
