Cost Overview
Installing solar panels in Pennsylvania typically ranges from $12,000 to $25,000 for a standard 6‑kW residential system before incentives. After federal tax credits and state rebates, the net cost often falls between $8,000 and $18,000. These figures include panels, inverters, racking, wiring, permits, and installation labor.

Factors That Shape the Price
Several variables affect the final bill:
- System Size – Larger arrays generate more power but require more panels and a bigger inverter.
- Roof Type – Metal or shingle roofs can influence mounting costs; a new roof adds $1,500‑$3,000.
- Orientation & Shade – South‑facing roofs with minimal shade reach the high end of the cost spectrum.
- Permitting & Inspection – Municipal fees average $200‑$500 but vary by locality.
- Financing Choice – Buying outright or leasing can change cash flow but not total cost.
Incentives That Reduce the Bottom Line
Key incentives include:
- Federal Investment Tax Credit (ITC) – 30% of the system cost (as of 2026) applied before state rebates.
- Pennsylvania State Rebate – Up to $2,500 for qualifying residential installations.
- Local Utility Programs – Some utilities offer additional rebates or net‑metering credits.
