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

The 8 kW Huntington baseline

Most homeowners we quote in Huntington, Greenlawn, and Northport land on a system between 7 and 10 kW — enough to offset roughly 95% of their 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, since the federal tax credit applies to storage retrofits even after the initial install.

Federal Investment Tax Credit (30%)

The federal residential clean energy credit covers 30% of the gross system cost — panels, inverters, batteries, labor, sales tax, the whole stack. It is a tax credit, not a deduction: it reduces your federal tax bill dollar-for-dollar. Any unused credit rolls forward.

On the $26,000 8 kW baseline, that is an $7,800 federal credit. The credit is scheduled to step down after 2032 but is locked in at 30% through end of 2026.

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

New York stacks its own 25% solar credit on top of the federal credit, capped at $5,000. On the $26,000 baseline, that is the full $5,000.

Like the federal credit, it is dollar-for-dollar against your state tax bill, with carry-forward if you cannot use it all in one year.

NYSERDA NY-Sun rebate (varies by queue)

NYSERDA pays a per-watt rebate that flows through your installer at the point of sale. The amount drops as each block fills — current Long Island block (Block 12 as of mid-2026) pays roughly $0.20/W to $0.30/W. On 8 kW that is $1,600–$2,400 off the gross.

This is paid as a discount on the install price — you do not have to file paperwork to claim it.

Net cost + payback math

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

Gross install: $26,000. Less federal 30% credit ($7,800), NY State credit ($5,000), NYSERDA block rebate ($2,000 mid-range). Net out-of-pocket: roughly $11,200.

Average Huntington home produces ~10,400 kWh/year from an 8 kW system. At LIPA's mid-2026 effective residential rate of ~$0.27/kWh delivered, that is $2,808/year in displaced electricity. Net payback: 4.0 years (extremely fast — LIPA rates have risen 4–6% annually, accelerating payback further).

After payback, the panels keep producing for the remaining 18–20 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) means more displaced electricity and a shorter payback — sometimes under 3 years on heavy-use homes.

Lower-incentive blocks (NYSERDA queue fills) drop the rebate to $0.10/W or zero. That pushes payback out by 6–9 months.

Battery storage adds ~$13K but is also covered by the 30% federal credit, so net add is ~$9K. Payback math depends on time-of-use rate exposure and outage frequency.

Bottom line: most Huntington homes hit payback in year 5–7, even with conservative 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 federal 30% credit, NY State 25% credit (capped at $5,000), and NYSERDA NY-Sun rebate, net out-of-pocket is typically $11,000–$15,000.

How long is the payback period for solar in Huntington?

Most Huntington homeowners see 5–7 year payback at current LIPA rates. Heavy-electric homes (heat pumps, EVs, pools) often pay back in 3–4 years; lighter-use homes 7–8 years.

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

Yes — they are stackable. You can claim the federal 30% Investment Tax Credit AND the New York State 25% residential solar credit (capped at $5,000). Both are dollar-for-dollar tax credits, not deductions.
