Pennsylvania gets limited sunshine — about 3.9 peak sun hours a day — and residential electricity runs around $0.18/kWh. For a typical $150-a-month power bill, that points to roughly a 8.8-kW system costing about $26,344 — with no federal tax credit, which ended for installations completed after December 31, 2025 — paying for itself in about 14.6 years and netting on the order of $35,021 over 25 years. Your own numbers will differ — the calculator above uses your real bill.
Pennsylvania has limited sun but an active SREC market and above-average rates, so a right-sized system pays back reasonably. Check current SREC prices, which swing the math noticeably.
What changes the math in Pennsylvania
- Your electricity rate — the more you pay per kWh, the more each solar kWh saves you. Pennsylvania sits at about $0.18.
- Sun hours — more sun means a smaller, cheaper system covers the same usage. Pennsylvania averages ~3.9 hours.
- Net metering / buyback — how your utility credits power you export swings the payback; check your specific utility's current terms.
- Install cost — quotes vary by installer and roof; the calculator defaults to a typical $/watt you can override.
Common questions
Is solar worth it in Pennsylvania?
For a typical $150-a-month Pennsylvania power bill, this calculator points to roughly a 14.6-year payback on a 8.8-kW system, using 3.9 peak sun hours a day and an electricity rate near $0.18/kWh. That is a directional estimate, not a quote — your roof, your utility's export rules and the spread between installer quotes all move it.
Does Pennsylvania still have the 30% federal solar tax credit?
No. The federal Residential Clean Energy Credit (IRC §25D) ended for systems whose installation was completed after December 31, 2025, so a Pennsylvania system finished today gets no federal credit and this calculator subtracts none. State, utility and local incentives are unaffected and can be entered by hand.
