Long Island Solar Pros — Calculator
See your Long Island solar snapshot
A planning estimator built around PSEG Long Island, the New York State 25% solar equipment credit, NYSERDA solar + storage, and the realities of Long Island roofs. Ranges, not promises.
How this calculator works
The output below is a planning estimate for Long Island homes using transparent assumptions: a PSEG-realistic residential rate placeholder, a Long Island capacity factor, your stated roof sun exposure, and the New York State 25% Solar Energy System Equipment Credit (capped at $5,000). Federal residential incentives have changed — we do not assume a federal residential credit on 2026 estimates and verify any active federal program during the consultation.
For a written, itemized quote built around your actual roof and your last 12 months of PSEG bills, request a Long Island solar assessment.
PSEG Long Island residential bills typically range from $120 to $500+.
Planning estimate
Your Long Island solar snapshot
Mockup ranges only. Real numbers come from your roof, your PSEG bill, and your tax situation.

- 7.5–10.1 kW
- Estimated monthly bill offset
- 70–95% (~$175–$238/mo)
- NY State 25% solar credit (estimated, capped at $5,000)
- ~$4,700–$5,000
Battery backup
We design the system to be battery-ready so adding storage later is straightforward. NYSERDA storage incentives may apply if you add later — we verify program rules at the time.
Roof readiness
No problem — we evaluate roof condition as part of the assessment.
Financing note
We model cash, loan, and lease side by side so you can compare on the same system.
A note on accuracy
This is a planning estimate. Actual costs, incentives, production, and savings depend on your roof, usage, utility account, installer pricing, and tax situation.
Federal residential incentives have changed. The IRS Residential Clean Energy Credit applied to qualified clean energy property installed from 2022 through December 31, 2025 and is not available for property placed in service after that date. We do not assume a federal residential credit on 2026 estimates and verify any active federal program during the consultation.
Incentives change and eligibility varies. Confirm details with the program administrator and a qualified tax professional.
