How We Rank States for Solar in 2026
Our rankings combine four weighted factors to determine overall solar viability: electricity rates (35% weight), peak sun hours (25%), state incentives and rebates (25%), and net metering policy quality (15%). A state with moderate sunshine but sky-high electricity rates and generous incentives can outrank a sun-drenched state where power is cheap.
Top 10 States for Solar in 2026
| Rank | State | Avg Rate ($/kWh) | Peak Sun Hours | Payback (Years) |
|---|---|---|---|---|
| 1 | California | $0.32 | 5.8 | 5–7 |
| 2 | Massachusetts | $0.28 | 4.2 | 5–7 |
| 3 | New York | $0.24 | 4.0 | 6–8 |
| 4 | New Jersey | $0.18 | 4.4 | 6–8 |
| 5 | Connecticut | $0.27 | 4.1 | 6–8 |
| 6 | Rhode Island | $0.26 | 4.1 | 6–9 |
| 7 | Arizona | $0.14 | 6.4 | 7–9 |
| 8 | Colorado | $0.15 | 5.5 | 7–10 |
| 9 | Maryland | $0.16 | 4.5 | 7–10 |
| 10 | Texas | $0.14 | 5.6 | 8–11 |
Why Electricity Rates Matter More Than Sunshine
The most common misconception about solar is that the sunniest states are the best for solar. In reality, electricity rates are the dominant factor in solar ROI. Massachusetts with 4.2 peak sun hours and $0.28/kWh electricity produces a faster payback than Arizona with 6.4 peak sun hours but only $0.14/kWh electricity. Every kilowatt-hour your panels generate is worth twice as much in Massachusetts.
The High-Rate Advantage
States in the top five all share electricity rates above $0.18/kWh. At these rates, a 7 kW system saving 9,000 kWh/year generates $1,620–$2,880 in annual savings — enough to achieve payback in 5–8 years after the federal ITC. Visit your state page to see local rate trends.
Net Metering Quality by State
Net metering policy determines how much you earn for excess solar sent to the grid. This has become increasingly important as utilities nationwide restructure their solar export policies.
- Full retail net metering: Massachusetts, New Jersey, Maryland, New York — you earn full retail rate for exports
- Reduced export rates: California (NEM 3.0 at ~$0.05/kWh export), Arizona (varies by utility), Nevada
- No statewide mandate: Texas, Georgia, Alabama — policies vary by utility
States Where Solar Is Challenging
Low Rate + Low Sun States
States like Washington, Oregon, and Idaho combine cheap hydroelectric power ($0.10–$0.12/kWh) with moderate sun hours, pushing payback periods to 15–20+ years. Solar can still work here for energy independence, but the financial case is weaker.
Low Rate + Good Sun States
Louisiana, Oklahoma, and Arkansas enjoy plentiful sunshine but some of the cheapest electricity in the nation ($0.09–$0.11/kWh). Even excellent solar production struggles to deliver payback under 15 years at these rates.
Emerging Solar Markets to Watch
Several states are climbing the rankings due to new incentive programs and rising electricity rates:
- Illinois: The Illinois Shines program and rising ComEd rates are making solar increasingly attractive
- Maine: Strong net metering plus high and rising electricity rates
- Minnesota: Community solar and solar garden programs expanding access
