Solar makes financial sense in all 50 states — but the ROI varies dramatically based on utility rates, net metering policies, and state incentives. Here's how the top states stack up in 2025.
The Key Variables for Solar ROI
- Utility rate: Higher electricity prices = faster payback. Hawaii ($0.39/kWh), California ($0.29/kWh), and Massachusetts ($0.25/kWh) lead the country.
- Net metering: How much your utility pays for excess solar generation. Full retail net metering (common in most states) maximizes your return.
- Sun hours: Southwest states get 5–7 peak sun hours/day vs. 3–4 in the Northeast. But higher electricity rates often offset lower sun hours.
- State tax incentives: Some states still add credits or rebates, which matter more now that the federal credit has ended.
Top 5 States for Solar ROI in 2025
1. Hawaii: Highest electricity rates in the nation + abundant sun = fastest payback (5–7 years). Hawaii also has a state solar tax credit.
2. California: High rates, excellent sun, and robust utility rebate programs. NEM 3.0 reduced export rates but self-consumption + battery storage keeps ROI strong.
3. Massachusetts: SMART program pays homeowners for solar generation. Combined with high electricity rates and state incentives, payback is 7–9 years despite modest sun hours.
4. New Jersey: SREC market pays homeowners for solar renewable energy certificates. Strong net metering and high electricity rates make NJ a top-10 market.
5. Texas: Lots of sun, no state income tax and no state solar credit, and rising electricity rates accelerating payback periods.
Don't Overlook These States
With the federal solar credit gone for 2026 installs, state and utility programs matter more. They vary widely by state and utility, and HomeShark lists the programs we know of for your state.
