🏆 Top 10 States for Solar Energy in 2026
We rank states based on a combination of solar resource (PSH), electricity rates, state incentives, net metering policies, and installation costs.
| Rank | State | Avg PSH | Electricity Rate | Federal ITC | State Incentive |
|---|---|---|---|---|---|
| 1 | Arizona | 6.5 | $0.14/kWh | 30% | Property tax exemption |
| 2 | California | 5.8 | $0.30/kWh | 30% | SGIP battery rebate |
| 3 | Nevada | 6.2 | $0.12/kWh | 30% | Net metering 1:1 |
| 4 | New Mexico | 6.3 | $0.14/kWh | 30% | Solar tax credit (10%) |
| 5 | Colorado | 5.5 | $0.14/kWh | 30% | Property tax exemption |
| 6 | Texas | 5.2 | $0.14/kWh | 30% | Property tax exemption |
| 7 | Utah | 5.8 | $0.11/kWh | 30% | Solar tax credit (10%) |
| 8 | Hawaii | 5.3 | $0.42/kWh | 30% | Self-supply program |
| 9 | Massachusetts | 4.2 | $0.28/kWh | 30% | SMART program |
| 10 | New York | 3.8 | $0.23/kWh | 30% | NY-Sun rebate |
Best States by Solar Resource (Peak Sun Hours)
These states have the best solar resources — more sunlight means smaller, cheaper solar arrays:
- Arizona — 6.5 PSH (best in the continental US)
- New Mexico — 6.3 PSH
- Nevada — 6.2 PSH
- California (desert) — 6.0 PSH
- Utah — 5.8 PSH
A system in Arizona needs only half the solar panels as the same system in Washington state. That's why location matters so much — use our NREL-powered calculator to get your exact numbers.
States with the Best Solar Incentives
Beyond the federal 30% Investment Tax Credit (ITC), these states offer additional incentives that significantly reduce solar costs:
- California: Self-Generation Incentive Program (SGIP) — up to $1,000/kWh for battery storage
- New York: NY-Sun program — up to $5,000 off residential solar
- Massachusetts: SMART program — guaranteed payments for solar production
- Colorado: Property tax exemption — no increase in property taxes from solar
- Oregon: Solar + Storage Rebate program — up to $5,000
The ITC alone reduces your solar system cost by 30% with no cap. Combined with state incentives, many homeowners see payback periods of 5-8 years in top-tier states.
Best States for Off-Grid Solar
For off-grid solar specifically, the best states offer three things: high sun hours, lenient building codes, and affordable land:
- 🏜️ Arizona — Best solar resource, but hot summers reduce panel efficiency
- 🏔️ New Mexico — Excellent sun, cool climate = great panel performance
- 🏔️ Colorado — 300+ sunny days, strong off-grid community
- 🌲 Maine — Growing off-grid community, lower land costs (but fewer sun hours)
- 🌲 Texas (West) — Cheap land, good sun, minimal regulations
No matter where you are, our calculator uses real NREL data for your specific city — so you get accurate numbers for any location.
Worst States for Solar
These states face challenges for solar adoption:
- Washington — Low sun hours (2.8-3.5 PSH), but cheap hydroelectric power
- Alaska — Extreme seasonal variation (very little sun in winter)
- West Virginia — Low sun hours, limited state incentives
- Kentucky — Below average sun, low electricity rates (longer payback)
Even in these states, off-grid solar can still make sense for remote cabins where grid connection costs more than solar. Use our calculator to see your specific numbers.
