Pennsylvania Solar Incentives, Cost & Payback (2026)
Written by Aditya Patil · Last updated 2026-09-24
Pennsylvania offers one of the best environments for residential solar on the East Coast thanks to its robust 1:1 net metering policy for investor-owned utilities and an active SREC market.

Cost of solar in Pennsylvania
While exact median installed costs for Pennsylvania vary, a conservative estimate based on national trends puts residential installations around $3.15/watt in 2026.
For a typical PA household using 9,418 kWh/year, you would need roughly a 7.24 kW system to offset your full usage. At our estimated rate, this system would cost about $22,811 gross. Since the federal residential clean energy credit (§25D) doesn't apply to systems completed after 2025-12-31, the 2026 net cost for a cash or loan purchase remains $22,811.

Battery hardware cost isn't included in the payback estimate above. In Pennsylvania, a battery provides backup power but does not accelerate payback.
Net metering / export rules
Pennsylvania boasts one of the most straightforward and favorable net metering policies in the country. Investor-owned utilities (like PECO, PPL, and FirstEnergy) are required to offer 1:1 net metering at the full retail rate for residential systems up to 50 kW.
This means that every kilowatt-hour (kWh) your system sends to the grid offsets a kWh you consume later, dollar for dollar.
| Policy | 1:1 Full Retail Net Metering (up to 50 kW residential) |
| Rollover | Monthly credits roll over indefinitely until the May 31 true-up |
| Annual true-up | Remaining excess credited at the lower Price to Compare (PTC) rate |
| Availability | Mandatory for Investor-Owned Utilities (PECO, PPL, FirstEnergy, etc.) |
| Warning | Alternative suppliers (EGS) or rural co-ops may not offer 1:1 net metering |
Excess generation is credited at the full retail rate (which includes both generation and distribution components) and rolls over from month to month. At the end of the annual true-up period on May 31, any remaining bank of excess credits is compensated at the lower Price to Compare (PTC) rate, which covers only the generation and transmission portions of the bill.
Incentives & SRECs
Pennsylvania's main ongoing financial incentive is the Alternative Energy Portfolio Standard (AEPS) SREC program. SRECs provide an ongoing revenue stream that stacks with your regular electricity bill savings.
| Program | Amount | Status |
|---|---|---|
| Alternative Energy Portfolio Standard (AEPS) — SREC | 1 SREC is earned for every 1,000 kWh (1 MWh) of solar electricity generated. These credits can be sold on the SREC market, with prices fluctuating based on supply and demand. | open |
Top utilities
| Utility | Residential rate | Customers |
|---|---|---|
| FirstEnergy Pennsylvania Electric Co | 17.37¢/kWh | 1,464,054 |
| PECO Energy Co | 16.16¢/kWh | 1,205,013 |
| PPL Electric Utilities Corp | 16.99¢/kWh | 797,773 |
Residential rate and customer counts are from EIA-861 (see Data sources below).

FAQ
Is solar worth it in Pennsylvania?
Yes. Pennsylvania has a strong 1:1 net metering policy for investor-owned utilities like PECO and PPL, meaning you are credited at the full retail rate for electricity your panels send to the grid. With electricity rates currently at 21.73¢/kWh, a typical solar installation pays for itself relatively quickly, even without federal tax credits in 2026.
Do I need a home battery with my solar panels in PA?
Financially, no. Because Pennsylvania offers 1:1 net metering, the electric grid essentially acts as your free battery. You receive full credit for the excess energy you produce during the day, which offsets the power you pull from the grid at night. Adding a battery in PA is primarily a lifestyle choice for backup power during outages, not a financial necessity.
How do SRECs work in Pennsylvania?
Pennsylvania has an Alternative Energy Portfolio Standard (AEPS) that allows solar owners to earn Solar Renewable Energy Certificates (SRECs). You earn one SREC for every 1,000 kWh (1 MWh) your system generates. You can sell these SRECs on a market, providing an additional ongoing revenue stream on top of your electricity bill savings.
