Solar payback in Pennsylvania (2026)
In Pennsylvania, a typical 8 kW home-solar system costing about $24,000 ($3/W, no federal credit in 2026) has an estimated simple payback of 10.7 years and roughly $43,325 in net savings over 25 years. This assumes an average rate of 20.92¢/kWh and ~1,180 kWh produced per kW each year.

Above-average rates and a tradable SREC market help, but Pennsylvania SREC prices are volatile, so payback estimates that exclude SRECs are the conservative case.

Frequently asked questions
What is the solar payback period in Pennsylvania?
For a typical 8 kW system costing about $24,000 ($3/W) with no federal tax credit in 2026, the estimated simple payback in Pennsylvania is roughly 10.7 years, based on an average residential rate of 20.92¢/kWh and a production factor of about 1,180 kWh per kW per year. Your actual payback depends on your quote, usage and net-metering rules.
Is solar worth it in Pennsylvania now that the federal tax credit has expired?
The 30% federal residential credit (Section 25D) expired on December 31, 2025, which raises the up-front cost of 2026 installs by about 30%. Above-average rates and a tradable SREC market help, but Pennsylvania SREC prices are volatile, so payback estimates that exclude SRECs are the conservative case.
How much electricity does an 8 kW system produce in Pennsylvania?
About 9,440 kWh in year one (8 kW × 1,180 kWh/kW), declining slowly as panels degrade ~0.5% per year.
