In 2026, Pennsylvania solar installations typically cost $2.95–$3.50 per watt installed, including equipment, labor, permits, and utility interconnection. For an average 8–10 kW system, that puts the total before incentives between $24,000 and $35,000. Two factors make Pennsylvania more expensive than neighboring states: no sales tax exemption (PA’s 6% sales tax adds $1,500–$2,100 to a typical install) and no property tax exemption for the added home value. Use our Pennsylvania solar panel calculator to estimate the cost for your specific system size.

The typical payback period for a cash solar purchase in Pennsylvania is 10–13 years in 2026, after the federal residential tax credit expired at the end of 2025. Before the credit expired, payback was 7–9 years. With a solar loan, add 2–3 years for interest. Payback is driven primarily by your utility’s electricity rate, how much your system produces, and your net metering credits. PECO and PPL customers in southeastern Pennsylvania generally see the shortest paybacks due to higher electricity rates. Erie and northwest PA typically see longer paybacks due to lower average sun hours.

A typical Pennsylvania homeowner with a properly sized solar system saves $1,400–$2,400 per year through net metering credits, plus $250–$520 per year in SREC income — totaling roughly $1,650–$2,920 annually. Over 25 years (the typical system lifespan), that’s $41,000–$73,000 in total savings before accounting for utility rate increases, which have averaged 3–4% annually in PA. The exact amount depends on your utility, how much electricity you use, and whether you own or lease your system. Lease and PPA holders typically save 10–20% on their monthly bill but don’t earn SRECs.

Yes — the long-term economics remain solid, though payback periods are longer. The core drivers of Pennsylvania solar savings (net metering, SRECs, and rising utility rates) are completely independent of the federal tax credit. Pennsylvania electricity rates have climbed 29% since 2021, which means every kilowatt-hour your system produces is worth more each year. Homeowners planning to stay in their home 10+ years still see strong lifetime returns. The bigger change in 2026 is that leases and PPAs have become more competitive relative to cash purchases — the solar company can still claim the commercial tax credit (Section 48E) and pass savings through as lower monthly rates.

Net metering is Pennsylvania’s policy requiring utilities to credit your account at the full retail rate for every kilowatt-hour your solar panels send to the grid. It’s the largest driver of solar savings in PA — worth $1,400–$2,400 per year for a typical system. Credits accumulate monthly and settle annually on May 31. Without net metering, solar economics would be significantly weaker since you’d only benefit from electricity your home uses in real time. Important warning for PPL customers: PPL Electric has proposed replacing 1-to-1 net metering credits with lower hourly wholesale rates, potentially effective July 2026. This could substantially reduce savings for PPL territory homeowners in the Lehigh Valley, Harrisburg area, and Scranton. Systems installed before the change may be grandfathered.

For Pennsylvania homeowners who can afford the upfront cost, a cash purchase delivers the highest lifetime return — no interest payments, no monthly obligations, and you keep all net metering credits and SREC income. A solar loan is the right choice if you want system ownership without the large upfront payment — monthly loan payments are often lower than the electric bill savings from day one. A lease or PPA makes sense if minimizing upfront cost and monthly payment is the priority, or if you plan to sell within 5 years. In 2026, leases are more competitive than before because the solar company can still claim the commercial tax credit and pass savings through as lower rates.
