Best States for Off-Grid Solar in 2026
Key Takeaways
- Arizona is the #1 state for off-grid solar — best sun, strongest property rights, minimal permits.
- New Mexico and Texas round out the top three for the combination of sun, freedom and available land.
- The best states combine high sun hours WITH strong off-grid property rights — sun alone isn't enough.
- California has excellent sun but complex regulations and high costs make it less ideal than Arizona.
- The worst states for off-grid solar combine low sun hours with restrictive regulations.
Ranking methodology
Each state is scored on five equally-weighted factors:
- Peak sun hours — average daily solar resource (annual average)
- Property rights — freedom to live off-grid, rainwater collection, composting toilets, etc.
- Permit burden — ease of permitting a residential off-grid solar installation
- State incentives — property tax exemptions, sales tax exemptions, state credits
- Land affordability — availability of rural land suitable for off-grid living
Top 10 states for off-grid solar
#1
Arizona
94/100
6.5h peak sun/day $0.134/kWh avg rate Property tax exempt Sales tax exempt
Arizona tops every category. It gets the most consistent sunshine in the continental US — Phoenix averages 299 sunny days per year. Strong solar property protections, no state income tax on solar production, 100% property tax exemption on solar added value and minimal permitting requirements in most rural counties. The combination of best-in-nation sun and strong legal framework makes Arizona the clear #1.
#2
New Mexico
87/100
6.5h peak sun/day $0.134/kWh avg rate 10% state tax credit Property tax exempt
New Mexico offers the rare combination of excellent solar resource, a state tax credit and strong off-grid property rights. Rural New Mexico has extensive public land adjacency with minimal development restrictions. The 10% state income tax credit for solar (capped at $9,000) applies to both grid-tied and off-grid systems. Affordable rural land and a strong off-grid living tradition make it an excellent choice.
#3
Texas
83/100
5.5–6.0h peak sun/day $0.155/kWh avg rate Property tax exempt No state income tax
Texas has strong property rights, no state income tax (making solar savings fully tax-free), and a 100% property tax exemption on solar added value. The Texas Hill Country and West Texas offer abundant affordable land with excellent solar resource. Rural counties have minimal permit requirements. The main drawback is that electricity rates are moderate — not as high as coastal states — which slightly reduces the financial impact of going off-grid.
#4
Nevada
82/100
6.4h peak sun/day $0.145/kWh avg rate Property tax exempt No state income tax
Nevada has the second-highest solar resource in the nation after Arizona, no state income tax and a solar property tax exemption. Large amounts of affordable rural land in northern Nevada are accessible for off-grid development. Las Vegas and Reno areas have stricter regulations but rural counties are very permissive.
#5
Colorado
78/100
5.5h peak sun/day $0.148/kWh avg rate Property tax exempt Strong off-grid laws
Colorado has some of the strongest off-grid property rights in the nation — Colorado law explicitly protects the right to collect rainwater and live off-grid. Mountain counties have excellent solar resource despite higher latitude due to thin air and frequent clear skies. Abundant land in the San Luis Valley and southeastern plains at affordable prices.
#6
Montana
74/100
4.5–5.0h peak sun/day $0.12/kWh avg rate Property tax exempt Minimal regulations
Montana scores exceptionally on property rights and regulatory freedom — among the most permissive states for off-grid living. Affordable land, minimal county regulations and a strong tradition of rural self-sufficiency. Lower on the list because electricity rates are low (reducing the financial savings) and sun hours are moderate. Best for those who prioritise freedom over financial optimisation.
#7
Tennessee
72/100
4.5h peak sun/day $0.138/kWh avg rate No state income tax Rural land affordable
Tennessee has no state income tax, affordable rural land in the Cumberland Plateau and east Tennessee mountains, and moderate electricity rates. Off-grid living is well-established in rural areas with minimal county-level restrictions. Sun hours are average for the Southeast but the combination of low land costs, tax environment and regulatory freedom makes it a strong overall choice.
#8
Missouri
70/100
4.5h peak sun/day $0.128/kWh avg rate Property tax exempt Affordable land
Missouri offers very affordable rural land (among the cheapest in the country), a full solar property tax exemption and minimal rural county regulations. The Ozarks have a strong tradition of rural self-sufficiency. Solar resource is average for the Midwest — adequate for a well-sized system but not exceptional.
#9
Florida
69/100
5.5h peak sun/day $0.135/kWh avg rate Property tax exempt No state income tax
Florida has excellent solar resource, no state income tax and a full solar property tax exemption. North Florida rural counties have affordable land and minimal regulations. The main drawbacks: hurricane risk requires robust mounting, humidity accelerates corrosion and building codes in many counties are stricter due to hurricane standards. Best suited to the rural Florida panhandle and north-central areas.
#10
Wyoming
68/100
5.0h peak sun/day $0.113/kWh avg rate No state income tax Minimal regulations
Wyoming offers exceptional regulatory freedom, no state income tax and good solar resource. Low electricity rates reduce the financial savings calculation, but for those prioritising independence over pure ROI, Wyoming's combination of cheap land, minimal government and strong property rights is hard to beat.
States to avoid for off-grid solar
| State | Main issues |
|---|---|
| Alaska | Very low winter sun, extreme cold, high system cost |
| Washington | Low sun hours, complex regulations, high land cost near population centres |
| New Jersey | High land cost, strict regulations, low rural availability |
| Massachusetts | High land cost, complex permitting, moderate sun |
| Hawaii | Excellent sun but very high system costs, strict utility regulations, high land cost |
Frequently asked questions
Is California good for off-grid solar?
California has excellent sun but falls outside the top 10 due to complex regulations, high land costs near population centres, strict building codes and the overall high cost of living. In rural areas of eastern California (Mojave, high desert), off-grid solar is entirely feasible — but the regulatory and cost environment is more challenging than Arizona or Nevada.
What state has the most off-grid homesteads?
Tennessee, Missouri and Texas have the highest concentrations of established off-grid homesteads based on community surveys and land purchase data. The combination of affordable land, moderate climate and permissive regulations drives this. Arizona and New Mexico have growing off-grid communities particularly in the Verde Valley, Taos and Silver City areas.
