Solar Financing on Long Island

Cash, loan, lease, or PPA — what is actually best for you

Cash typically has the cleanest math. You capture the New York State 25% credit (and any active federal credit you qualify for) directly, you pay no finance charges, and you own the system outright. Cash is not always feasible — but when it is, it is usually the strongest option.

Solar loans are common on Long Island. Many are advertised as "$0-down" — the trade-off is a dealer fee built into the price and a reamortization clause that historically assumed a 30% federal tax credit applied. With federal residential incentives changed, that loan structure deserves an even closer read; we walk through the assumptions before you sign.

Leases and PPAs transfer tax credits to the leasing company. Sometimes the math still benefits the homeowner. Often it does not — especially without a federal residential credit to anchor the savings narrative.

Tax-credit interaction with financing

Tax credits — including the New York State residential solar credit and any active federal residential incentive — only apply to the system owner. With a loan or cash, you are the owner. With a lease or PPA, the leasing company is the owner. That single fact drives most of the financing math.

Federal residential solar incentives have changed. We verify current eligibility during the consultation and walk through how the active program interacts with each financing path.

How the financing comparison works

The planning assessment models the same system size across the relevant financing options so you can compare apples-to-apples — cash, loan, lease, and PPA on the same equipment. Conservative assumptions are shown alongside best-case numbers, with explicit notes on which incentives are anchoring each scenario. Final loan rates, terms, and qualification come from your chosen lender; final design and savings come from your licensed local installer.
