Solar in California: Frequently Asked Questions

Is solar worth it in California after NEM 3.0?
Yes — despite lower export credits, California's electricity rates (25–35¢/kWh) are among the highest in the US. Self-consumed solar still saves at the full retail rate, and a battery storage system can capture excess production for evening use. The average payback period is 5–7 years.
What is the SGIP rebate in California?
The Self-Generation Incentive Program (SGIP) offers rebates of $150–$1,000 per kWh of battery storage installed. For a 13.5 kWh Powerwall, that can mean $2,000–$13,500 back. Check with your utility for current availability.
How much does solar cost in California?
The average solar installation in California costs $2.37–$3.14 per watt, or $17,000–$22,000 for a 7 kW system before incentives. The federal solar tax credit (Section 25D) expired December 31, 2025.
What is California's solar net metering policy?
California uses NEM 3.0 (since April 2023). Excess solar sent to the grid earns credits at the 'avoided cost' rate (~5¢/kWh) rather than the retail rate. New solar owners should size systems for self-consumption and consider battery storage.

Going Solar in California: Step by Step

From first quote to first kilowatt — here is the typical timeline for a residential solar installation in California. Most homeowners complete this process in 6–12 weeks.

  1. 1
    Get 3 quotes

    Prices in California average $22,400 for an 8 kW system before incentives. Getting three quotes typically saves 10–15%. Use the same system size so you can compare apples to apples.

  2. 2
    Review your electricity bill

    Your last 12 months of usage determines the right system size. At 30.29¢/kWh in California, a system that offsets 90% of your bill hits the best cost-per-kWh sweet spot.

  3. 3
    Check state incentives

    California does not have a statewide solar tax credit, but utility rebates and net metering may still apply. SGIP battery rebate (up to $1.

  4. 4
    Sign contract & apply for permits

    Your installer pulls the building permit and files interconnection paperwork with your utility. Permit approval in California typically takes 1–4 weeks depending on your county.

  5. 5
    Installation day

    A standard 8 kW residential installation takes 1–2 days. Racking goes on first, then panels, then the inverter is wired to your main panel. The crew usually keeps the power on throughout.

  6. 6
    Utility inspection & interconnection

    After installation your utility inspects the system and approves grid connection. This final step can take 1–3 weeks. Once approved, your meter tracks both import and export.
