Best states for solar incentives (2026)

New York has the best solar incentives in 2026 — a 25% state income-tax credit worth up to $5,000, stacked on top of full retail-rate net metering and tax exemptions. Massachusetts and New Jersey are close behind. But “best” now means something different than it did a year ago: with the 30% federal credit gone as of December 31, 2025, your state’s programs are no longer a bonus on top of the federal benefit — they’re the whole benefit. Where you live decides your return more than it ever has.

What counts as a “good” incentive now

Post-2025, four different mechanisms move the needle, and the strongest states combine several:

• State income-tax credits — a direct percentage back on your system cost. Only a handful of states offer one, and the caps matter as much as the rate.
• Net metering vs. net billing — how your utility credits exported power. Full retail net metering is worth far more over 25 years than avoided-cost “net billing,” and it’s often the single biggest factor.
• Production incentives — programs that pay you per kilowatt-hour or per megawatt-hour produced, for years. New Jersey’s SuSI and Massachusetts’s SMART are the standouts.
• Sales- and property-tax exemptions — quieter, but they waive sales tax on equipment and keep your property taxes from rising on the added home value.

A state credit with no net metering can be worth less than a state with no credit but full retail net metering. That’s why the ranking below weighs the whole stack, not just the headline credit.

The 2026 ranking

Rates are EIA residential averages for the 12 months through July 2026. Every figure is an estimate — verify current program terms on DSIRE and with your utility before you commit.

The top tier: a credit plus strong net metering

New York tops the list because it stacks the most. Its 25% state income-tax credit is capped at $5,000 — the highest cap in the country — with a five-year carryforward, and it sits on top of Phase One net metering that still locks new residential customers into full 1:1 retail crediting for 20 years, plus a sales-tax exemption and a 15-year property-tax exemption. See the details at New York solar incentives.

Massachusetts pairs a 15% credit (capped at $1,000) with something rarer: the SMART production incentive, which pays $0.03 for every kWh your panels produce, locked in for 20 years once you qualify — $0.06 for income-qualified households — stacked on full retail net metering. Add one of the country’s highest electricity rates at 30.4¢/kWh, and Massachusetts delivers one of the strongest overall returns even with a modest credit cap.

New Jersey has no income-tax credit, but its SuSI/ADI program makes up for it by paying you for what your system produces, per megawatt-hour, for 15 years. The rate stepped down after the BPU’s three-year review: systems registered on or after July 27, 2026, earn $77/MWh, versus $85/MWh for earlier registrations. Combined with mandated retail-rate net metering, a full sales-tax exemption, and a high 23.8¢ retail rate, that ongoing payment is why New Jersey ranks this high. The full picture is at New Jersey solar incentives.

The middle: one strong lever each

Arizona offers a 25% credit, but it’s capped at just $1,000 as a lifetime limit per residence — most systems hit that cap immediately, so it functions as a flat $1,000. Its net-billing export rate (~6¢/kWh) is well below retail, which puts a premium on self-consumption. Details at Arizona solar incentives.

Florida has no credit but a genuinely valuable combination: full retail net metering from its major utilities, a permanent 6% sales-tax exemption, and a 100% property-tax exclusion. Texas relies on a 100% property-tax exemption and utility-specific programs — Austin Energy’s $4,000 rebate and 12.89¢/kWh Value of Solar are strong, while CPS Energy customers get far less. North Carolina leans on Duke Energy’s PowerPair rebate (up to ~$9,000 for solar plus a battery) and an 80% property-tax exclusion — but PowerPair has been closed in Duke Energy Progress territory since November 7, 2025, and the Duke Energy Carolinas allotment is nearly full as of October 2026, so treat it as a maybe, not a line item. See the PowerPair guide and North Carolina solar incentives.

The bottom: high rates, thin incentives

Nevada credits exports at 75% of retail for 20 years — decent — but NV Energy’s daily demand charge for southern-Nevada residential customers (scheduled for October 1, 2026, and under legal challenge) is expected to raise rooftop-solar bills by about $12 a month, and new northern-Nevada customers now net exports every 15 minutes instead of monthly. California is the paradox of the list: it has the highest residential electricity rate in the lower 48 (33.0¢/kWh) and no state credit, and its NEM 3.0 net billing credits exports at roughly a quarter of retail (our calculator values a California export at 22% of retail). Solar still pays in California — but because power is so expensive, not because the incentives are good, and the property-tax exclusion is set to sunset January 1, 2027. Georgia rounds out the list with no credit and a low ~7.2¢/kWh buyback.

What this means for your decision

A great incentive stack shortens payback; it doesn’t create it. Run the calculator’s default inputs for each of these 10 states and the fastest estimated paybacks are New York (about 7.6 years), Massachusetts (about 8.8) and California (about 9.1) — first, second and ninth on this ranking — while Georgia trails at about 16.5 years. A high electricity rate can matter more than any credit, and how your utility values exports matters almost as much. Use the incentive picture to understand what’s available, then run your own bill through the solar savings calculator, which already assumes a 0% federal credit for 2026 and, in the net-billing states (California, Arizona, Nevada, and Georgia’s buyback), values the half of your output it assumes you export at 22–75% of retail.
