Is solar worth it in Great Neck, NY? For most owner-occupied homes, yes. According to MySolarFY’s analysis (as of July 2026), a typical 7.5 kW Great Neck rooftop system produces roughly 9,000 kWh a year, and at New York’s 28.55 cents per kWh residential rate under PSEG Long Island net metering it offsets about $2,570 of electricity in the first year, for a simple payback near 8 years after the 25% New York state income-tax credit (capped at $5,000). The federal 25D homeowner credit ended December 31, 2025, but New York’s state credit and net metering did not. This is a planning estimate; your roof, usage, and which village permits your project drive the real number.
- Your permit office depends on which Great Neck village you live in. The peninsula holds nine incorporated villages, and each one runs its own building department, so a Kings Point project and a Great Neck Plaza project go to different counters (Village of Great Neck Building Department, as of June 2026).
- New York’s statewide fast-track solar permit excludes Nassau County. The New York State Unified Solar Permit is “for use in all New York State counties with the exception of Nassau County and Suffolk County,” so Long Island uses its own separate permit instead (NYSERDA New York State Unified Solar Permit, as of June 2026).
- New York power is expensive, which is what makes solar pay. New York residential electricity averages about 28.55 cents per kWh (EIA, as of March 2026), and PSEG Long Island’s rates sit among the highest in the state and have been rising.
- PSEG Long Island still offers net metering to new rooftop solar. Your bidirectional meter bills you on net usage and banks extra credits across a 12-month period (PSEG Long Island solar; DSIRE PSEG Long Island net metering, as of June 2026).
- New York’s 25% state tax credit survives even though the federal one ended. New York gives a state income-tax credit worth 25% of the system cost, capped at $5,000 (NY Department of Taxation and Finance, as of 2026), while the 30% federal homeowner credit (Section 25D) ended for systems placed in service after December 31, 2025 (IRS, as of January 1, 2026).
- The NY-Sun cash rebate for a standard-income Long Island home is gone. The standard residential Megawatt Block for the Long Island region is fully subscribed; only the low-income Affordable Solar block (about $0.40 per watt) remains (NYSERDA Long Island Dashboard, as of 2026).
Great Neck solar adds up fast, because the power it replaces is expensive and New York still rewards the people who make their own. The wrinkle in this corner of Nassau County is not whether solar works on the North Shore, it is the paperwork: the Great Neck peninsula is a cluster of nine incorporated villages, each with its own building department, and New York’s usual fast-track solar permit does not even apply here. This page covers what solar really costs in Great Neck, the New York incentives you can still claim in 2026, how PSEG Long Island credits the power your roof sends back, and exactly which permit office you deal with depending on your village. Updated for July 2026.
Why Great Neck’s electric rates make solar worth it
The reason solar pays in Great Neck is the price of the power it offsets. New York residential electricity averages about 28.55 cents per kWh (EIA, as of March 2026), well above the national average, and PSEG Long Island customers sit near the top of the state’s range, with rates that have climbed again in 2026. Great Neck’s larger North Shore homes, with central air conditioning, pools, and in many cases electric heat or EV charging, tend to run high annual usage, so every kilowatt-hour your roof produces offsets an expensive one you would otherwise buy. A household spending $200 or more a month on electricity is a strong solar candidate here. For the exact cents on your own bill, read the supply and delivery lines on your PSEG Long Island statement, since both move on their own schedules.
Your production is what turns that high rate into savings. NREL’s PVWatts model puts a typical, well-oriented Long Island rooftop array at roughly 1,150 to 1,250 kWh per year for every kW of panels you install (a regional estimate from NREL PVWatts for the Long Island area, not a live reading for your roof, as of 2026). Output depends on your roof’s pitch, shading, and orientation, and Great Neck’s mature tree canopy and closely spaced homes can shade parts of a roof, so treat that band as a regional estimate and run PVWatts for your own address before you size anything. Your production drives your net-metering credits, so it is worth getting right.

What solar costs in Great Neck, and when it pays back
Here is the part most pages skip: the actual math for this area. We built the estimate below from the data already on this page, the New York residential rate and a typical Long Island production band, against a typical Nassau County installed price. Treat it as a planning estimate, not a quote. The inputs are shown so you can follow the math and swap in your own numbers, and you can see how we build these estimates.
Assumptions: each kW of panels produces about 1,200 kWh per year (the midpoint of the 1,150 to 1,250 kWh per kW band that NREL PVWatts models for the Long Island area, as of 2026); each kWh is valued at the 28.55 cent New York residential rate (EIA, as of March 2026), since PSEG Long Island net metering credits a typical home near its retail rate; an installed price of $3.40 per watt before incentives, the middle of the roughly $3.20 to $3.60 per watt range reported for Nassau County (NYSERDA Paying for Solar, as of 2026); and the 25% New York state tax credit, capped at $5,000 (NY Department of Taxation and Finance, as of 2026); and the LIPA Customer Benefit Contribution, about $1.13 per kW of system size per month for systems interconnected after 2021, which we subtract from year-one savings (NYSERDA 2026 Customer Benefit Contribution rates, as of 2026). No federal credit is included, because the federal homeowner credit ended for systems placed in service after December 31, 2025.
| System size | Est. annual production | Est. first-year bill savings | Less LIPA CBC ($1.13/kW-mo) | Cost before incentives | Cost after the 25% NY credit | Simple payback |
|---|---|---|---|---|---|---|
| 5 kW | about 6,000 kWh | about $1,710 | about $68/yr | $17,000 | $12,750 | about 7.8 years |
| 7.5 kW | about 9,000 kWh | about $2,570 | about $102/yr | $25,500 | $20,500 | about 8.3 years |
| 10 kW | about 12,000 kWh | about $3,430 | about $136/yr | $34,000 | $29,000 | about 8.8 years |
Note: This is a simplified estimate that holds today’s rate flat and ignores financing costs, so treat it as a starting point. Two things tend to push the real payback shorter: PSEG Long Island rates have been rising, which raises the value of every kilowatt-hour you offset, and the New York credit is a tax credit, so you need enough New York tax liability to use it (it is non-refundable but carries forward up to five years). As a rough sensitivity check, at about 3% annual rate growth the 7.5 kW payback shortens from roughly 8.3 years toward the low-7-year range, since every kilowatt-hour you offset is worth more each year. A written quote that uses your actual roof, usage, and a current production estimate beats any table. See whether solar panels are worth it for the full payback framework.
New York’s solar incentives still standing in 2026
The headline for Great Neck is that the state benefits survived even though the federal one did not. A homeowner here can still stack a state income-tax credit, a sales-tax exemption, and, in most cases, a property-tax exemption. The one that disappeared for a standard-income home is the NY-Sun cash rebate. Each of these goes to the system owner, so on a lease or PPA the company that owns the panels keeps the tax benefits, while your net-metering bill credit still follows your PSEG Long Island account.
| Incentive | What it is worth | Status for a Great Neck home in 2026 |
|---|---|---|
| New York State income-tax credit for solar (Form IT-255) | 25% of system cost, capped at $5,000, non-refundable, carries forward 5 years | Active. Available for a purchase, a written lease, or a 10-plus-year PPA (NY Tax Dept) |
| New York sales-tax exemption | No state sales tax, plus Nassau County’s local exemption | Active. Residential solar is generally fully sales-tax exempt on Long Island (NY Tax Dept) |
| RPTL Section 487 property-tax exemption | 15 years with no added property tax on the value the system adds | Available statewide, but each county, town, village, and school district can opt out, so verify with your assessor (DSIRE) |
| NY-Sun Megawatt Block (Long Island) | A per-watt cash rebate paid through your installer | Standard residential block is closed; only the low-income Affordable Solar block (about $0.40 per watt) remains (NYSERDA) |
The New York state tax credit is the big one for a Great Neck buyer. It is worth 25% of your qualified system cost up to a $5,000 lifetime cap per residence, claimed on Form IT-255, and it applies whether you buy the system, sign a written lease, or sign a power-purchase agreement of at least ten years (NY Department of Taxation and Finance, as of 2026). It is non-refundable, so it offsets New York tax you owe and any leftover carries forward for up to five years.
Two property-tax points are easy to get wrong here. First, New York’s RPTL Section 487 exemption keeps your property taxes from rising on the value solar adds, for 15 years, but it is subject to local opt-out by the county, town, village, and school district, so confirm it with the Nassau County Department of Assessment and your village and school district before you count on it (DSIRE, as of 2026). Second, the well-known New York City solar property-tax abatement is a New York City program for the five boroughs only, so a Great Neck home in Nassau County does not get it. If you want to see how a New York City market with a different utility and that abatement compares, read how solar works in Brooklyn. For the full statewide picture, see our New York solar guide and the broader solar incentives overview.
What the federal tax-credit change means for Great Neck
The federal homeowner credit is gone, but New York’s programs are not. The 30% federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act, and the IRS treats the expense as made when installation is completed, so a Great Neck homeowner who installs solar with cash or a loan in 2026 cannot claim it (IRS Residential Clean Energy Credit; SEIA, as of 2026). You will still see installer pages and search results implying the 30% credit is available; the accurate answer for 2026 is that the homeowner version already ended. New York’s state credit, the sales-tax exemption, and net metering were not affected, and at PSEG Long Island’s high rates the bill offset alone is substantial.
One federal exception exists, and it is not yours to claim. A separate commercial credit, Section 48E, can be claimed by the business that owns a leased or PPA system, not by the homeowner (IRS Clean Electricity Investment Credit, as of 2026). On a leased system you do not file for a federal credit yourself; the company that owns the panels does. The 25D homeowner credit, by contrast, ended after December 31, 2025. For the full timeline, see what the federal solar tax credit change means in 2026.
How PSEG Long Island credits the power your roof sends back
Net metering is the engine of your savings, and PSEG Long Island still offers it to new rooftop solar. When your panels make more than you use, the extra flows to the grid and your bidirectional meter banks the difference as a credit, so you are billed on your net kilowatt-hours over the period (PSEG Long Island solar; DSIRE PSEG Long Island net metering, as of June 2026). New residential rooftop systems stay on net metering rather than being pushed onto the Value Stack tariff that New York uses for community and larger projects. Credits roll forward across a 12-month net-metering period, and any leftover balance at the end of that period is cashed out at a lower wholesale buy-back rate. One small fixed cost does apply: New York solar customers who interconnect after 2021 pay a Customer Benefit Contribution, and for LIPA the 2026 residential rate is about $1.13 per kW of system size per month, which we subtract in the payback table above (NYSERDA 2026 Customer Benefit Contribution rates, as of 2026). For the mechanics behind all of this, see how net metering credits your solar exports.
| What happens | How PSEG Long Island handles it |
|---|---|
| Your panels make less than you use | You buy the difference from the grid at the retail rate |
| Your panels make more than you use | The excess is banked as a credit and rolls forward through the 12-month period |
| Leftover credit at the end of the period | Cashed out at a lower wholesale buy-back rate, so size the system close to your usage |
| The fixed daily service charge | Stays on your bill; net-metering credits offset energy, not the basic service charge |
| The LIPA Customer Benefit Contribution | About $1.13 per kW of system size per month for systems interconnected after 2021, a small fixed cost we subtract in the payback table |

The Great Neck permit maze: which village are you in?
This is the part of going solar in Great Neck that surprises people. The Great Neck peninsula is not one town. It is nine incorporated villages, Great Neck, Great Neck Estates, Great Neck Plaza, Kensington, Kings Point, Lake Success, Russell Gardens, Saddle Rock, and Thomaston, plus unincorporated pockets governed by the Town of North Hempstead. Each incorporated village administers New York’s building code locally and runs its own building department, so the office that issues your solar permit, the forms you file, and the review you go through all depend on your exact address (Village of Great Neck permits and forms; Village of Great Neck Estates Building Department, as of June 2026). It is no accident that a Google search for solar in Great Neck surfaces village permit pages alongside installers.
Note: New York’s statewide fast-track permit does not help you here. The New York State Unified Solar Permit is written “for use in all New York State counties with the exception of Nassau County and Suffolk County,” so Great Neck projects use a separate streamlined Long Island permit instead, the LIPA-sponsored Solar Energy System Fast Track Permit Application, filed with your village building department (NYSERDA New York State Unified Solar Permit, as of June 2026). Expect your village to ask for a current property survey by a licensed surveyor, two sets of plans, and a plot plan, and budget a few extra weeks if your village adds architectural review. An installer who works the Great Neck villages regularly will know each counter’s quirks.
| If your home is in | Your solar permit goes to |
|---|---|
| Village of Great Neck, Great Neck Estates, or Great Neck Plaza | That village’s own building department |
| Kings Point, Russell Gardens, Saddle Rock, Thomaston, Kensington, or Lake Success | That village’s own building department |
| An unincorporated part of the Great Neck area | The Town of North Hempstead Building Department |
Paying for solar in Great Neck: cash, loan, lease, or PPA
There is no single right way to pay for solar; the best fit depends on whether you want to own the system and claim the New York state credit yourself, or avoid an up-front cost. The table compares the common paths. A lease or PPA can mean no up-front cost for eligible homeowners, but it is a long-term agreement with monthly payments, not free solar, and the system owner, not you, keeps the New York state tax credit. To weigh the long-run numbers, see whether solar panels are worth it.
| Path | Up-front cost | Who keeps the NY state tax credit | Best when |
|---|---|---|---|
| Cash purchase | Full system cost | You, the owner | You want the fastest payback and the most lifetime savings |
| Solar loan | Little to none, financed | You, the owner | You want ownership without paying cash up front |
| Lease or PPA | $0-up-front where eligible | The third-party owner | You prefer no up-front cost and a simpler, fixed monthly bill |
How to choose a solar installer in Great Neck
Great Neck sits in a deep Long Island solar market, with local Nassau County companies and regional brands competing, which is good for you because it means real competition on price and service. Rather than chasing a “best installer” list, screen any company against objective criteria:
- NABCEP certification, the industry’s professional standard for PV installers.
- A valid New York State and Nassau County license and electrical licensing, and registration in your specific village if it requires one.
- A clear workmanship and equipment warranty in writing.
- Real experience with PSEG Long Island interconnection and your village’s permit process, since the village building department, not a single town office, signs off on Great Neck projects.
- A written production estimate and a transparent quote that reflects the incentives that actually apply to you, including the New York state credit and the fact that there is no federal homeowner credit in 2026. For a checklist, see the right questions to ask a solar installer.
MySolarFY matches you with licensed installers that serve your area so you can compare real local quotes side by side, with no obligation.

Frequently asked questions
Is solar worth it in Great Neck in 2026?
For most owner-occupied Great Neck homes with decent sun, yes. New York residential electricity averages about 28.55 cents per kWh (EIA, as of March 2026), and PSEG Long Island’s rates run near the top of that range and have been rising, so every kilowatt-hour your roof makes offsets an expensive grid one. Net metering credits a typical home near its retail rate, and New York’s 25% state tax credit, capped at $5,000, lowers your net cost. Using a typical Nassau installed price, our estimate puts simple payback near 7 to 9 years. Savings are not guaranteed and depend on your roof, usage, and how you pay, but the high local rate is what makes Great Neck a strong solar market.
Who is my utility for solar in Great Neck, and does PSEG Long Island still offer net metering?
PSEG Long Island, which operates the grid for the Long Island Power Authority, is your electric utility, and yes, it still offers net metering to new residential rooftop solar in 2026. Your bidirectional meter bills you on net usage, banks extra generation as credits that roll forward across a 12-month period, and cashes out any leftover balance at a lower wholesale rate (PSEG Long Island solar; DSIRE, as of June 2026). New residential rooftop stays on net metering rather than the Value Stack tariff used for larger projects. The fixed daily service charge stays on your bill, since credits offset energy, not that charge.
Which solar incentives can a Great Neck homeowner still get in 2026?
The main one is New York’s state income-tax credit for solar, worth 25% of your system cost up to a $5,000 lifetime cap, claimed on Form IT-255 and available for a purchase, a written lease, or a 10-plus-year PPA (NY Tax Dept, as of 2026). Residential solar is also generally exempt from state and Nassau County sales tax, and the RPTL Section 487 exemption can keep your property taxes from rising on the added value for 15 years, though it is subject to local opt-out, so verify it with your assessor (DSIRE, as of 2026). The NY-Sun cash rebate for a standard-income Long Island home is closed; only a low-income block remains.
What happened to the federal solar tax credit?
The 30% federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act, so a Great Neck homeowner who installs solar with cash or a loan in 2026 cannot claim it (IRS, as of 2026). A separate commercial credit, Section 48E, can apply to leased and PPA systems, but the business that owns the system claims it, not the homeowner. New York’s state credit, sales-tax exemption, and PSEG Long Island net metering were not affected, so the local payback case still holds. See our guide on what the federal solar tax credit change means in 2026.
Do I need a special permit for solar in Great Neck?
Yes, and the office depends on your village. The Great Neck peninsula is nine incorporated villages plus unincorporated areas, and each village runs its own building department, so your solar permit is filed with your village, not a single town office (Village of Great Neck permits, as of June 2026). New York’s statewide fast-track Unified Solar Permit excludes Nassau and Suffolk Counties, so Long Island uses a separate streamlined permit, the LIPA-sponsored Solar Energy System Fast Track Permit Application, instead (NYSERDA, as of June 2026). Expect to provide a current survey, two sets of plans, and a plot plan, and allow extra time if your village adds architectural review.
Can I get solar with no up-front cost in Great Neck?
Some homeowners can, through a lease or power purchase agreement (PPA) where eligible, which can mean no out-of-pocket cost at installation in exchange for monthly payments. This is not free solar; it is a long-term agreement, typically 20 to 25 years, that may include an annual price escalator, and total payments may exceed the cost of a cash purchase. On a lease or PPA the third-party owner, not you, keeps the New York state tax credit, and there is no homeowner federal credit in 2026, because the federal residential credit ended after December 31, 2025. If you want to own the system and claim the New York credit yourself, a cash purchase or solar loan is the path that keeps it. Check what you qualify for before deciding.
