Home Solar Cost Guide

What California pays for your exported solar power

Export compensation is the single biggest payback lever in 2026. Here is California's current rule in plain words, with the official source.

Under California's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.

Installed home solar for Belmont homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.

Belmont, California has about 27,132 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.

Beware of any 2026 payback estimate that looks as good as the 2025 ones: with the federal credit gone, a third of the old subsidy math vanished. If a sales projection has not gotten noticeably worse since 2025, it is hiding something - usually an inflated utility-rate escalation assumption.

Whether solar still pays in California after the federal credit's end comes down to arithmetic, not ideology: installed cost (about $2.58 a watt at the marketplace average), what your utility pays for exports, and how much of your generation you use yourself. High self-consumption - daytime usage, EV charging, batteries - is now the biggest lever.

California rules that decide your payback

RuleCalifornia status
Export compensation (net metering)Net billing, not retail net metering: the CPUC's Net Billing Tariff (NBT, commonly called "NEM 3.0") took effect April 15, 2023 and credits exported electricity at hourly avoided-cost "value to the grid" rates that are usually well below the retail rate, while customers already on NEM 2.0 may stay on that legacy tariff for 20 years from their interconnection date.
State incentiveSelf-Generation Incentive Program (SGIP) - Residential Solar and Storage Equity incentives (storage $1,100/kWh, solar $3,100/kW), open for reservations since June 2, 2025 with a $280 million budget, but limited to low-income/equity-qualified customers; there is no general statewide solar rebate or state income tax credit.
Sales tax on the systemNot exempt - taxed like any purchase
Property tax on added home valueExcluded

California is the only state that requires solar PV on most newly built homes (2025 Energy Code / Title 24 Part 6, applicable to permit applications filed on or after January 1, 2026), and its long-standing property-tax exclusion for solar is scheduled to be repealed on January 1, 2027.

What this means for Belmont roofs

The honest 2026 answer for Belmont: solar pays back slower without the 30% credit - paybacks that ran 7-10 years often now run 10-14 - but electricity rates keep rising and hardware is the cheapest it has ever been. The deciding factor is California's export compensation, covered in the net metering section.

Getting Belmont quotes

The spread between the highest and lowest bid for the same roof routinely hits 30-50%, because solar quotes carry very different sales overheads. Two or three independent bids collected against the same system size is the single highest-value hour in the whole project.

Common questions

What happens if my installer goes out of business?

Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.

How long do solar panels actually last?

Panels are typically warrantied for 25 years of production and commonly outlive it, losing about 0.5% output per year. Inverters are the component that usually needs replacement - typically once, around year 12-15, at a few thousand dollars.

Should I lease, get a PPA, or buy?

Buying keeps all savings and any incentives with you. Leases and PPAs put a company's equipment on your roof for 20-25 years, complicate a home sale, and in 2026 any tax benefits they advertise belong to the company under commercial rules - not to you. Read escalator clauses carefully.

Does solar raise my property taxes?

It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.

How do I check if a solar quote is fair?

Divide the total price by the system's wattage. The U.S. marketplace average is about $2.58 per watt installed; $2.30-3.00 covers most fair quotes depending on roof complexity. Above that, ask exactly what you are paying extra for - in writing.
