Local reality

What actually matters in Levittown

The things a national calculator has no way to know.
  • Levittown is the most uniform housing stock in New York State — thousands of near-identical 1947-1951 Cape Cods. That uniformity means quotes are unusually comparable here, and the price spread between them is therefore unusually revealing.
  • It also means near-universal 100A original services and small roof planes. Anyone quoting you a 12 kW system on an original Levitt Cape has not looked at the roof.
  • PSEG Long Island operates under LIPA's tariff, not the PSC's. Statewide net-metering and CBC guidance does not automatically apply.

The 30% federal solar tax credit is gone for direct purchases.

Section 25D — the Residential Clean Energy Credit — terminated for expenditures after December 31, 2025 under Public Law 119-21. If you did not have a system installed and operational by the end of 2025, it is not available to you. Signing a contract or paying a deposit in 2025 was not enough.

Third-party ownership (a lease or a PPA) can still access the 48E business credit through the statutory window, but that credit is claimed by the system owner, not by you. Whether any of it reaches your monthly payment is a question for the contract, not the brochure.

New York's own credit is unaffected: Form IT-255 still gives 25% of qualified solar equipment cost, capped at $5,000 lifetime, with a five-year carryforward.

If a proposal for a Levittown address still shows a 30% federal credit, ask the salesperson to point you to the IRS guidance that allows it. There is not any. Current program status →

Levittown by the numbers

The inputs this page is built on

Every figure below carries its source and the date we last checked it. If one of them is wrong for your address, the rest of this page is wrong too — so start here.

Delivery utility

PSEG-LI

Nassau County, Suffolk County, and the Rockaways.

All-in cost of power

$0.22–$0.29/kWh

Plus a $17 monthly basic service charge that solar cannot remove.

Filed PSEG Long Island tariff schedule · verified Apr 2026

Specific yield

1,220–1,360 kWh / kW-DC / yr

Long Island climate zone. Dec–Feb is about 14% of the annual total.

Modeled NREL PVWatts v8 · verified Jan 2026

Snow and design load

20–45" / yr · 20–30 psf

No lake-effect exposure.

Filed ASCE 7 ground snow load data · verified Jan 2026Snow load is low here, but wind load requirements are the highest in the state and drive the racking spec instead.

Elevation

60 ft

Elevation drives snowfall totals and design load more than latitude does in this part of the state.

Installer market

Saturated

Heavily worked market. The lowest cash prices and the highest financed prices in the state coexist here.

Permitting authority

Town of Hempstead Building Department

Permits are issued by your town, city, or village — not the county. Timelines and fees vary block to block across a single county. The NYS Unified Solar Permit is broadly used in this area.

Housing stock

100A typical

Dominated by 1946-1965 tract housing. Original 100A services are common, and many were never upgraded past the first kitchen remodel.

Reported monthly bills

$150–$265

Range that readers on this route have shared with us. Yours depends on usage, rate, and whether an alternative supplier is on your bill.

ZIP codes covered

How this page is built

This is a generated page: the structure is shared across locations, the numbers are not. Every figure comes from the source cited beside it, with the date we last checked it. Nothing here is a quote, an appraisal, or tax advice, and none of it is specific to your roof.

Rates and incentive programs change. We re-verify utility tariffs and NYSERDA program status on a rolling schedule and stamp the date on each number rather than on the page, so you can see which specific figures are fresh. Full methodology · Program status tracker · About the Local Energy Playbook
