Best States for Going Solar in 2026

What makes a state good for solar

It surprises almost everyone, but sunshine is not the top factor in whether solar pays off. Four things matter more, in roughly this order:

1. Electricity rate. The higher your retail rate, the more each solar kWh saves you. This is the number-one driver, full stop.
2. Net metering. Full-retail 1:1 credit beats net billing — it sets the value of every exported kilowatt-hour.
3. Incentives. State tax credits, rebates and SREC markets that stack on the federal 30%.
4. Sun hours. Genuinely important, but it cannot rescue a state with cheap power and weak policy.

This is precisely why Hawaii and the Northeast outrank far sunnier states: their expensive electricity makes solar savings enormous. A kilowatt-hour avoided in Hawaii (~41¢) is worth nearly four times one avoided in Washington (~11¢).

Top states for solar payback in 2026

Notice how many are in the Northeast — not a sunny region, but one where electricity is expensive and policy is supportive. That combination beats sunshine every time.

Sleeper states worth a look

Some states fly under the radar but offer strong value in 2026:

• Illinois — the Illinois Shines SREC program pays a 15-year block of credits upfront, effectively covering a large share of system cost.
• North Carolina — one of the largest solar markets in the country, with strong sun and a history of Duke Energy programs.
• New Mexico — a 10% state tax credit on top of some of the best sunshine in the nation.
• New Jersey — modest sun, but the SuSI program and full net metering make it a perennial top performer.

The lesson: don't judge a state by its weather. Judge it by rates, net metering and the incentive stack on the state incentives hub.

Where solar pays back slowest

Solar still works almost everywhere thanks to the federal credit, but it pays back slowest in states that combine cheap electricity with weak incentives — regardless of how sunny they are:

Even here, panels last 25–30 years, so a 13-year payback still leaves over a decade of nearly free power — see our lifespan and ROI guide. Slower payback is not the same as a bad investment.

The incentive types that move the needle

Beyond the federal 30% credit, the state-level incentives that most affect payback are:

• SRECs (Solar Renewable Energy Certificates) — tradable credits you earn for generating solar, sold for ongoing income in states like Illinois, New Jersey, Maryland and Pennsylvania. These can be worth thousands over time.
• State tax credits — e.g., Hawaii's 35% and New Mexico's 10%, claimed on your state return on top of the federal credit.
• Upfront rebates — flat grants (Maryland's $1,000) or per-watt utility rebates that cut your install cost directly.
• Property and sales tax exemptions — common and quietly valuable; they prevent solar from raising your property tax and waive sales tax on equipment.

The strongest solar states usually stack several of these, which is why their payback periods are years shorter than rates alone would suggest.

Solar by US region

Zooming out, each region has a characteristic solar profile:

• Northeast (CT, MA, NY, RI, ME, NH, NJ): modest sun but expensive electricity and supportive policy — consistently the best payback outside Hawaii.
• Mid-Atlantic (MD, PA, VA, DE): good rates plus active SREC markets make for solid mid-single-digit-year paybacks.
• Southeast (FL, GA, NC, SC): excellent sun but mixed policy; Florida's full net metering stands out, others rely more on the federal credit.
• Midwest (IL, OH, MI, WI, IN, MO): moderate sun and rates, lifted by programs like Illinois Shines and Focus on Energy.
• West & Mountain (NV, NM, UT, ID, WA, CO): abundant sun, but low rates in several states lengthen payback — New Mexico and Nevada are the standouts.
• Hawaii: in a class of its own thanks to the highest rates in the country.

How net metering reshuffles the rankings

If you re-ranked states purely on sunshine, the Southwest would top the list. But once you weight for net metering and rates, the picture changes completely. A state with full-retail net metering and 18¢ power beats a sunnier state with net billing and 12¢ power, because both the value per kWh and the value of exported surplus are higher.

This is why policy risk matters when you buy. A state moving from full-retail net metering to net billing — as several have — can lengthen new buyers' payback by years. The flip side is grandfathering: installing before a rollback often locks in the better terms for 10–20 years. If your state is debating a change, that is a strong reason to act sooner, and to confirm in writing which tariff your system will be enrolled under.

No good roof? Consider community solar

Not every home suits rooftop solar — a shaded lot, a north-facing or rented roof, or an HOA restriction can rule it out. In a growing number of states, community solar is the answer: you subscribe to a share of a local solar farm and receive credits on your utility bill for your share of its output, with no equipment on your roof.

Community solar typically saves 5–15% on the electricity it covers, requires no upfront cost, and is available to renters. It will not match the long-term ROI of owning panels (you do not get the 30% credit or build an asset), but it brings solar savings to households that otherwise could not participate. Check whether your state and utility offer a program; availability is expanding under IRA-era policy.

Your utility matters as much as your state

State is shorthand, but your specific utility often determines your actual deal. Rates, net metering tariffs and rebate programs frequently differ between utilities within the same state. A homeowner served by a high-rate investor-owned utility may have excellent solar economics while a neighbor on a cheap municipal or co-op utility a few miles away has weaker ones.

So once you have a sense of your state, drill down: look up your utility's current residential rate (¢/kWh), its net metering or net billing tariff, and any utility-specific rebates. Two homes in the same state can have paybacks years apart purely because of which utility serves them. The only way to know your real number is to run your own bill through the Payback Calculator.

Timing your install around policy

Because net metering and incentives evolve, when you install can matter almost as much as where. Three timing principles:

• Install before a net-metering rollback to lock in better terms via grandfathering, often for 10–20 years.
• Install during the 30% federal window (through 2032) to capture the maximum credit before the step-down.
• Watch SREC and rebate budgets — some state programs are capped and close once funds run out, so early movers benefit.

None of this means panic-buying; it means that if your state offers strong terms today, locking them in has real value, because the trend nationally is toward less generous export compensation over time.

Property and sales tax exemptions

Two quieter incentives meaningfully improve solar economics in many states, and they are easy to overlook:

• Property tax exemption. Adding solar raises your home's value (about 4.1% on average), which would normally raise your property tax. Most solar-friendly states exempt the added value, so you get the resale benefit without a higher tax bill. Florida, New York, New Jersey and many others offer this.
• Sales tax exemption. Several states waive sales tax on solar equipment, knocking 4–8% off the purchase price up front. Florida and Washington are notable examples.

Neither is as headline-grabbing as a tax credit or an SREC, but together they can be worth thousands over the system's life and at sale. They are part of why states with otherwise modest incentives can still pencil out well. Check which apply in your state on the incentives hub and DSIRE.

What to watch in 2026 and beyond

The solar policy landscape is shifting, and a few trends will shape which states are best in the years ahead:

• Net-metering reform continues to spread; expect more states to move from full retail toward net billing, raising the value of storage.
• Time-of-use rates are becoming the default for solar customers in more utilities, rewarding self-consumption and batteries.
• Rising retail rates — electricity prices have climbed faster than inflation in recent years, which quietly improves solar payback everywhere.
• The 2033 federal step-down means the 30% credit window is finite; states' rankings won't change that deadline.

The practical message: a great solar state today may tighten its terms tomorrow, so if your state currently offers strong net metering and incentives, there is real value in acting while they last and locking in grandfathered terms.

How to judge your own state

To assess your state in two minutes:

1. Check your electricity rate (it is on your bill, in ¢/kWh). Above ~18¢ is excellent for solar; 13–18¢ is solid; below ~12¢ is challenging.
2. Find your net metering rule on your state's incentive page — full retail is best, net billing is moderate.
3. Note any state credit, rebate or SREC market that stacks on the federal 30%.
4. Run your actual bill through the Payback Calculator for a personalized number that beats any state average.
