Solar Installers in California: Compare 2026 Quotes Without Sales Calls

What changed for California solar in 2026

Two structural changes hit California within three years of each other, and both are still shaping the math today.

NEM 3.0 (effective April 2023). California's Net Billing Tariff dropped utility credit for exported solar by roughly 75% compared to NEM 2.0. Where you used to get full retail rate (often $0.30 to $0.40 per kWh) for solar you sent to the grid, you now get something closer to $0.05 to $0.08 per kWh. The grid stopped functioning as a "free battery." Self-consumption became the new economic model.

Federal credit expiration (January 1, 2026). The 30% federal Residential Clean Energy Credit was the single biggest reason cash-purchased solar penciled out for California homeowners. A $40,000 system used to carry a $12,000 credit. In 2026 it does not. Cash purchase payback periods extended by roughly 3-5 years as a result.

Both changes pushed the same conclusion: a battery is no longer optional in California. Our deep dive on California solar after NEM 3.0 and the credit expiration walks through the full math.

When solar still pencils in California in 2026

Five things drive whether the math works for your specific home.

• Your utility rate. PG&E, SCE, and SDG&E peak time-of-use rates run $0.40 to $0.55 per kWh on hot summer afternoons. At these rates solar still pencils aggressively.
• Your monthly bill. Above $200/month solar clearly works. Above $300 it works well. Above $500 it works dramatically.
• Your roof. South-facing with full sun produces the most. Shaded or north-facing roofs weaken the self-consumption math NEM 3.0 makes essential.
• Pairing with a battery. Without storage, you export half your production at $0.06 per kWh and buy it back at $0.40. With a battery, you self-consume that stored solar in the evening peak window and keep the dollars.
• Financing structure. Cash and HELOC win for those with capital or equity. Prepaid leases are unusually competitive in California 2026 because the lease company still claims the 48E commercial credit and passes the value through.

California-specific incentives still in play

The federal residential credit is gone, but California has its own programs that still help:

• SGIP (Self-Generation Incentive Program). Pays rebates on battery storage, with higher rebates for homes in high fire-threat zones or on medical baseline.
• DAC-SASH and ERA programs. Income-qualified incentives for solar on disadvantaged community or low-income households.
• Property tax exclusion. California excludes the added value of an active solar system from your property tax assessment.
• Utility-specific demand response and battery rebate programs. Vary by utility. Worth asking about during the quote process.

None of these is as large as the old 30% federal credit was, but stacked together they can recover a meaningful portion of the gap.

How to compare California solar quotes

Get at least three quotes for the same project specs (same system size, same battery decision). For each one, ask the installer to show:

• System size in kilowatts and battery size in kWh
• Cash purchase price, financed price, and prepaid lease price for the equivalent system
• Annual production estimate and self-consumption estimate under NEM 3.0
• Total expected utility savings over 25 years, with assumptions visible
• All warranties in writing (product, performance, workmanship)

Compare the 25-year total cost for each scenario. The lowest one wins. For more on how to structure that comparison, see our pillar on comparing solar quotes apples-to-apples.
