Best States for Solar in 2026: All 50 Ranked by Payback
By Sunfinder Editorial Team · April 2026 · 8 min read
The federal solar tax credit expired on December 31, 2025. That changes the math for every state — payback periods are 2–4 years longer without the 30% federal credit. But solar still makes strong financial sense in high-rate states. Here is exactly where you stand, ranked from fastest to slowest payback.
Top 10 States: Fastest Solar Payback
| Rank | State | Payback | Rate (¢/kWh) | Annual yield | Annual savings |
|---|---|---|---|---|---|
| #1 | Hawaii | 3.3 yrs | 39.79¢ | 1441.6 kWh/kWp | $4,589/yr |
| #2 | California | 3.9 yrs | 30.29¢ | 1606.2 kWh/kWp | $3,892/yr |
| #3 | Massachusetts | 4.7 yrs | 31.16¢ | 1295.8 kWh/kWp | $3,230/yr |
| #4 | Maine | 4.8 yrs | 30.73¢ | 1271.8 kWh/kWp | $3,127/yr |
| #5 | Rhode Island | 4.8 yrs | 30.14¢ | 1293.8 kWh/kWp | $3,120/yr |
| #6 | Connecticut | 5.2 yrs | 28.3¢ | 1292.2 kWh/kWp | $2,926/yr |
| #7 | New York | 5.5 yrs | 28.37¢ | 1219.8 kWh/kWp | $2,768/yr |
| #8 | New Hampshire | 5.7 yrs | 26.32¢ | 1264.3 kWh/kWp | $2,662/yr |
| #9 | New Jersey | 6.2 yrs | 23.13¢ | 1308.4 kWh/kWp | $2,421/yr |
| #10 | Maryland | 7 yrs | 20.61¢ | 1318.6 kWh/kWp | $2,174/yr |
Why These States Win
The fastest solar payback states share two traits: high electricity rates and reasonable-to-good sun. Hawaii leads every ranking — at $0.40+/kWh, even a modest solar yield pays back in 3–4 years. Massachusetts and Connecticut follow, where rates above 28¢/kWh compensate for the relatively low sun.
California ranks highly despite NEM 3.0 export credit reductions. At 30¢/kWh, self-consumption alone justifies solar. New York and Rhode Island follow the same pattern: high rates drive fast payback regardless of solar yield.
Arizona and Nevada round out the top 10 by combining excellent sun (1,700–1,900 kWh/kWp/yr) with state-level incentives. Arizona's 25% state tax credit cuts $5,600 off an 8 kW system. Nevada's net metering program and strong yield make it consistently competitive.
Bottom 10 States: Slowest Payback
| Rank | State | Payback | Rate (¢/kWh) | Why it's slow |
|---|---|---|---|---|
| #50 | West Virginia | 14 yrs | 14.77¢ | Low rates + limited incentives |
| #49 | North Dakota | 13.4 yrs | 10.92¢ | Low rates + limited incentives |
| #48 | Washington | 12.3 yrs | 13.81¢ | Low solar yield |
| #47 | Missouri | 11.8 yrs | 11.8¢ | Low rates + limited incentives |
| #46 | Montana | 11.6 yrs | 12.86¢ | Low rates + limited incentives |
| #45 | Nebraska | 11.5 yrs | 11.76¢ | Low rates + limited incentives |
| #44 | Iowa | 11 yrs | 12.83¢ | Low rates + limited incentives |
| #43 | Arkansas | 11 yrs | 12.35¢ | Low rates + limited incentives |
| #42 | Tennessee | 10.9 yrs | 13.1¢ | Low rates + limited incentives |
| #41 | Idaho | 10.9 yrs | 12.07¢ | Low rates + limited incentives |
Low-Rate States: Still Worth It?
Louisiana, Washington, and North Dakota have electricity rates below 10¢/kWh. With payback periods of 14–18 years, solar is a marginal financial case in these states. If your primary motivation is energy independence or environmental impact, it still makes sense. If you want financial ROI, these states require careful analysis of your specific electricity bill, roof, and local utility rates before committing.
One exception: if you drive an EV, solar in low-rate states becomes more attractive. Charging your car with solar instead of grid power adds the equivalent of free fuel — worth roughly $1,000–$1,500/yr in driving costs, which can halve the effective payback period.
State Tax Credits That Change the Math
Key Takeaways
- High electricity rates matter more than sun. Massachusetts beats Arizona on payback.
- State tax credits can cut 2–4 years off your payback period.
- The federal ITC is gone — add 2–3 years to any pre-2026 estimates you've seen.
- EV charging can halve effective payback in low-rate states.
- Net metering policy matters as much as the rate — check your state's rules.
