How much does solar cost in Huntington, NY in 2026?

The 8 kW Huntington baseline

Most Huntington, Greenlawn, and Northport homes land on a system between 7 and 10 kW — enough to offset roughly 95% of annual electric usage. The 8 kW system is the mid-point and a useful baseline to anchor the cost conversation.

Installed cost for a turnkey 8 kW residential system in Huntington in 2026 is $24,000–$28,000. That covers panels (Tier-1 monocrystalline, typically Q Cells, REC, or SunPower), inverters (Enphase microinverters or a SolarEdge string + optimizers), racking, electrical work, permits, PSEG interconnection, monitoring, and the full 25-year panel + 12-year inverter warranties.

Battery storage is separate. A Tesla Powerwall 3 (13.5 kWh) adds about $13,000–$15,000 to the install. Most homeowners go solar-only first and add a battery later if outages become the deciding factor; there is no federal credit on a battery you buy in 2026.

The federal credit: ended for systems you buy

The 30% federal residential clean energy credit (IRC Section 25D) ended for expenditures made after December 31, 2025. A homeowner who buys a system in 2026 — cash or loan — does not get a federal credit. On the $26,000 8 kW baseline that credit was worth $7,800 in 2025; in 2026 it is $0.

Leased and PPA systems work differently: the company that owns the system, not the homeowner, may claim a separate commercial credit and can pass some of that saving through in the rate it charges. That is a pricing question to ask the provider, not a credit you file for. Confirm anything tax-related with your tax professional.

New York State residential solar tax credit (25%, capped)

New York's own residential solar credit is still in place: 25% of system cost, capped at $5,000. On the $26,000 baseline, that is the full $5,000.

It is dollar-for-dollar against your state tax bill, with carry-forward if you cannot use it all in one year. Your tax professional can confirm how it applies to your return.

NYSERDA NY-Sun rebate: exhausted for most Long Island homes

NYSERDA's NY-Sun per-watt rebate was paid in blocks, and the Long Island block for standard-income residential systems is exhausted. A 2026 quote for a standard-income household should show this line as $0.

Income-qualified pathways remain for some households. If a quote shows a NY-Sun rebate, ask which program it is drawn from before counting on it.

Net cost + payback math

Pulling it together for the 8 kW Huntington install at $26,000:

Gross install: $26,000. Federal credit: $0 (ended for 2026 purchases). NY State credit: $5,000. NY-Sun rebate: $0 for a standard-income household. Net out-of-pocket: roughly $21,000.

Assuming the home produces ~10,400 kWh/year from an 8 kW system and LIPA's mid-2026 effective residential rate of ~$0.27/kWh delivered, that is about $2,800/year in displaced electricity. Net payback: roughly 7.5 years. The same install in 2025, with the federal credit and a NY-Sun rebate, netted about $11,200 and paid back in about 4 years — that is the difference the law change made.

After payback, the panels keep producing for the remaining 17 or so years of the 25-year warranty — essentially free electricity once the system is paid off.

What changes the math

Higher LIPA usage (heat pump, EV, pool, large family) lets a larger system displace more electricity while the $5,000 state credit stays fixed, so payback moves toward the short end of the range on a good roof.

Shade, a north-facing roof plane, or a low electric bill push payback past 9 years. Rising LIPA rates pull it in — rates have risen 4–6% annually.

Battery storage adds ~$13K–$15K with no federal credit on a 2026 purchase. Treat it as the price of outage coverage, not as something that pays for itself.

Bottom line: most Huntington homes that buy in 2026 hit payback in year 7–9. A quote that shows a faster number should show its assumptions.

Frequently asked

What is the average cost of solar panels in Huntington, NY?

A typical 8 kW residential solar system in Huntington runs $24,000–$28,000 installed (before incentives). After the NY State 25% credit (capped at $5,000), net out-of-pocket is typically $19,000–$23,000. The 30% federal residential credit ended December 31, 2025 and does not apply to a system bought in 2026.

How long is the payback period for solar in Huntington?

Most Huntington homeowners who buy in 2026 see a 7–9 year payback at current LIPA rates, counting the NY State credit only. Heavy-electric homes (heat pumps, EVs, pools) on a good roof land at the short end; shaded or lighter-use homes can run past 9 years.

Can I combine the federal and NY State solar tax credits?

Not in 2026. The 30% federal residential credit ended for expenditures after December 31, 2025, so a system you buy in 2026 gets no federal credit. The New York State 25% residential solar credit (capped at $5,000) remains, and it is a dollar-for-dollar credit, not a deduction. Confirm with your tax professional.
