California Solar Payback Period: What Homeowners Need to Know in 2026
Last updated: 2026-06-15
Bottom line: California homeowners typically see a solar payback period of 9–13 years in 2026 — longer than it was before NEM 3.0, but batteries can pull that back toward 7–9 years for the right household.
What Changed With NEM 3.0
Since April 2023, California's net metering rules shifted dramatically. Under NEM 3.0, utilities pay you far less for excess power you export to the grid — in some cases 75–80% less than retail rates. PG&E, SCE, and SDG&E all follow this framework.
The result: solar alone pencils out more slowly than it used to. But self-consumption matters more than ever, which is why battery storage has become central to the California solar equation.
The Numbers: California Payback Estimate
| Factor | Estimate |
|---|---|
| Average electricity rate | $0.30–$0.38/kWh |
| Federal ITC (Section 25D) | EXPIRED — $0 (credit ended December 31, 2025) |
| CA property tax exclusion | Solar value excluded from assessment |
| Estimated annual savings (solar only) | $1,400–$1,800 |
| Payback period (solar only) | 9–13 years |
| Payback with battery (SGIP rebate) | 7–9 years |
California has some of the highest electricity rates in the country — that works in your favor. Every kWh you self-consume is worth $0.30+ instead of selling it back for $0.05.
Incentives That Still Matter
- Federal ITC (Section 25D): EXPIRED — The federal residential solar credit expired December 31, 2025. No federal credit is available for new solar or battery purchases in 2026.
- SGIP (Self-Generation Incentive Program): California rebates for battery storage, prioritizing low-income and high-fire-risk areas. Check current availability — the program runs in funding blocks.
- Property Tax Exclusion: The added home value from solar won't raise your property tax bill.
- No Sales Tax Break: Unlike some states, California does not exempt solar equipment from sales tax.
Is Solar Still Worth It in California?
Yes — especially if you have a time-of-use (TOU) rate plan and can shift consumption. Homes using most power during daylight hours, or adding a battery to cover evening peaks, still achieve strong long-term returns. Over a 25-year panel life, most California homeowners net $15,000–$35,000 after payback.

The Takeaway
Texas won't hand you a state rebate check. But high sun, a strong property tax break, and rising grid rates make solar a solid 10–15 year play for the right home.

Bottom line: Florida homeowners typically see a solar payback period of 10–12 years. The Sunshine State has real structural advantages — no state income tax, a sales tax exemption on solar equipment, and strong net metering — but moderate electricity rates keep payback from being as fast as California.
Florida's Solar Advantages Are Real
Florida is quietly one of the better solar states in the country, not because it offers big rebates (it doesn't), but because the policy framework is clean:
- Net Metering: Florida law requires investor-owned utilities (FPL, Duke Energy Florida) to credit excess production at retail rates. That's the same rate you pay — the best possible export deal.
- Sales Tax Exemption: Solar equipment is exempt from Florida's 6% sales tax. On a $17,400 system, that's ~$1,000 saved at purchase.
- Property Tax Exemption: The increased home value from solar is 100% excluded from property tax assessment.
The Numbers: Florida Payback Estimate
| Factor | Estimate |
|---|---|
| Average electricity rate | $0.13–$0.16/kWh |
| Federal ITC (Section 25D) | EXPIRED — $0 (credit ended December 31, 2025) |
| FL sales tax exemption | ~$1,000 saved upfront |
| FL property tax exclusion | Solar value exempted |
| Estimated annual savings | $1,200–$1,600 |
| Payback period | 10–12 years |
What Florida Doesn't Have
No state income tax credit. No state rebate program of significance. What you get is a clean net metering law and two purchase-price exemptions — that's the deal.
Hurricane and Battery Considerations
South Florida homeowners increasingly pair solar with battery backup. While it doesn't dramatically shorten payback (batteries add cost), it addresses a real risk: storm outages can run 5–14 days in some counties. Some insurance carriers and HOAs have begun adapting rules around rooftop solar — verify with your HOA and insurer before signing a contract.
Utility Differences Matter
- FPL (Florida Power & Light): Largest utility; net metering at retail rate, interconnection process is well-established.
- Duke Energy Florida: Same net metering framework.
- Municipal utilities (JEA, TECO, etc.): Policies vary slightly — confirm before installing.

The Takeaway
New York isn't the fastest solar market, but the combination of high rates, a generous state tax credit, and NY-Sun incentives makes it one of the financially strongest. Budget your time: the paperwork is real.

Bottom line: Arizona homeowners see solar payback in roughly 10–14 years in 2026. The sun is exceptional, but reduced export rates from major utilities — particularly APS — mean the math depends heavily on how much power you self-consume. SRP customers face a separate, more complex rate structure.
Arizona Has Two Very Different Utility Worlds
Which utility serves you determines your solar economics more than any other single factor:
- APS (Arizona Public Service): Moved away from retail-rate net metering. APS credits exported power at the Avoided Cost Rate — significantly below retail. As of recent filings, that's been in the $0.07–$0.10/kWh range versus paying $0.13–$0.16/kWh to consume grid power. Size your system to match consumption, not to maximize exports.
- SRP (Salt River Project): Operates under a demand-charge structure for solar customers. High peak demand charges can significantly impact monthly savings — some homeowners have seen higher bills after installing solar without a battery to flatten peak demand. Understand SRP's E-27 rate plan thoroughly before signing a contract.
- Tucson Electric Power (TEP): Generally more straightforward net metering; check current rates.
The Numbers: Arizona Payback Estimate
| Factor | Estimate |
|---|---|
| Average electricity rate | $0.13–$0.16/kWh |
| Federal ITC (Section 25D) | EXPIRED — $0 (credit ended December 31, 2025) |
| AZ State Tax Credit (25%, up to $1,000) | Up to $1,000 off state tax liability |
| AZ property tax exemption | Solar value exempted |
| AZ sales tax exemption | Solar equipment exempt |
| Estimated annual savings | $1,100–$1,500 |
| Payback period | 10–14 years |
Arizona's Incentive Stack
Arizona won't make you rich on incentives, but the stack is real:
- State Tax Credit: 25% of system cost, capped at $1,000. Applied against AZ income tax liability.
- Property Tax Exemption: Full value exemption on solar-added home value.
- Sales Tax Exemption: No sales tax on solar equipment purchase.
- Federal ITC: EXPIRED — The Section 25D residential credit ended December 31, 2025. Not available for new 2026 installations.
Sun Is Arizona's Real Advantage
Phoenix averages 5.5–6.5 peak sun hours daily — among the highest in the country. A 6kW system in Phoenix generates roughly 9,000–10,500 kWh/year, compared to 7,000–8,000 kWh for a similar system in Chicago. That production advantage is the underlying asset; the question is what your utility pays you for it.
Battery Storage and Arizona
A battery makes strong financial sense for APS customers specifically — it lets you store midday solar production and consume it during peak evening hours (when APS rates are highest), rather than exporting at low avoided-cost rates. For SRP customers, a battery can flatten peak demand and dramatically reduce demand charges.

The Takeaway
Arizona's sun is exceptional — but your utility contract matters as much as your solar contract. APS and SRP customers face reduced export compensation; right-sizing your system and adding battery storage changes the math significantly. Verify your utility rate plan in writing before you sign.
