- What payback period to expect and what factors influence it
Introduction
Solar returns in Pennsylvania come from three places: the electricity you stop buying, the SRECs your system earns, and the net metering credits that carry your summer surplus into winter. This guide walks through each one and how they combine into a payback figure.
The residential federal solar tax credit (Section 25D) expired on December 31, 2025, which means homeowners who purchase their system with cash or a loan no longer have access to the 30 percent federal credit. That changed the purchase math. It is one input among several that set the return.
Rising electricity rates, Pennsylvania’s SREC program, net metering credits, system costs and the financing path you choose all feed the total return. Here is how each one works and what it contributes.
The 2026 Solar Landscape in Pennsylvania
Before diving into ROI calculations, it is important to understand the current conditions that affect solar economics in PA.
Electricity Rates Are Rising
PECO residential customers are now paying an average total rate of approximately 20 cents per kWh, up over 20 percent from early 2025. Similar increases affect PPL, Met-Ed and other PA utilities. Every cent your electricity rate rises adds value to each kilowatt-hour you produce at home.

The Federal Residential Tax Credit Is Gone
As of January 1, 2026, homeowners who buy their solar system outright cannot claim the 30 percent federal tax credit. This was a significant incentive, and its expiration increases the net cost of a purchased system.
However, two important alternatives remain. First, homeowners who choose a solar lease or power purchase agreement (PPA) can still benefit from the commercial tax credit (Section 48E), which the leasing company claims and passes through as lower monthly payments. Second, the federal credit was never the only financial driver of solar ROI in Pennsylvania. State programs and utility savings carry substantial weight.
Pennsylvania’s State Incentives Remain Intact
SRECs (Solar Renewable Energy Certificates): Pennsylvania’s SREC market allows solar system owners to earn certificates for every 1,000 kWh of solar electricity produced. These certificates can be sold to utilities that need them to meet the state’s Alternative Energy Portfolio Standards. SREC values fluctuate based on market conditions, but they represent meaningful additional income on top of electricity bill savings.
Net Metering: Most Pennsylvania utilities support retail-rate net metering, meaning excess solar electricity sent to the grid earns credits at the same rate you would pay to consume it. This effectively allows your system to offset electricity use during non-producing hours.
Running the Numbers: A Realistic ROI Scenario
Solar ROI in PA is driven by three value streams that work together over the life of the system. The exact numbers depend on your home, your usage, and your roof, but the structure is the same for every homeowner.
Value Stream 1: Avoided Electricity Costs
Every kilowatt-hour your solar system produces is a kilowatt-hour you do not buy from the grid. With PECO’s total rate now averaging around 20 cents per kWh, the value of each unit of solar electricity you produce is meaningfully higher than it was even a year ago.
This is the largest component of solar ROI, and it compounds over time. Utility rates do not stay flat, they increase. If rates continue rising at even 3-4 percent per year (conservative based on recent trends), the value of your solar production in year 10 is significantly higher than in year one. Every rate increase that PECO, PPL, or any other PA utility passes through makes the electricity you already generate at home worth more.
Value Stream 2: SREC Income
Pennsylvania’s SREC market provides additional income on top of electricity savings. For every 1,000 kWh your system produces, you earn one SREC that can be sold to utilities that need them to meet the state’s Alternative Energy Portfolio Standards.
PA SREC values fluctuate with market conditions, but at recent prices in the $30 to $45 range per certificate, this adds a meaningful layer of income that most homeowners do not initially factor into their ROI calculations. SREC income is separate from and in addition to your electricity savings.
Value Stream 3: Net Metering Credits
When your system produces more than you consume, common during long summer days, the excess is sent to the grid and you receive a credit at the full retail rate. Those credits offset your electricity costs during evenings, cloudy days, and winter months when production is lower. Net metering effectively allows the grid to act as your battery, maximizing the value of every kilowatt-hour your system produces.
What Drives Payback and Long-Term Return
For homeowners who purchase their system with cash, the payback period depends on the relationship between system cost and total annual value (electricity savings plus SREC income). Without the federal tax credit, the upfront investment is higher than it was in 2025, which extends the payback timeline.
However, the 25-year value proposition has actually strengthened. Rate increases over the past two years have pushed the avoided-cost value of solar electricity well above what most projections assumed. A system that was modeled against 15-cent rates now operates against 20-cent rates, and that gap is likely to keep widening.
After a system reaches payback, it continues producing value for the remainder of its warranted lifespan, which typically extends to 25 years or more. The total lifetime return on a solar investment in PA generally exceeds the original cost by a significant margin.
How the Math Changes with a Lease or PPA
For homeowners who prefer not to make a large upfront investment, solar leases and PPAs offer a different financial profile. You do not own the system, but you pay a fixed monthly rate for the electricity it produces, which is lower than your current utility rate.
Critically, lease and PPA providers can still claim the federal commercial tax credit (Section 48E), which allows them to offer competitive pricing. The trade-off is that you do not own the system or earn SRECs directly, and total lifetime savings are lower than a cash purchase. In exchange there is no upfront cost, and the proposal can compare projected solar payments and remaining utility charges with your current bill.
What Makes Solar ROI Better (or Worse) in PA
Not every home gets the same return from solar. Here are the factors that move the needle most.
Is Solar Worth It in PA Without the Federal Tax Credit
For most Pennsylvania homeowners with a workable roof and meaningful electricity use, yes, and the reasoning is straightforward.
Without the 30 percent credit, a purchased system carries a longer payback than the same system would have in 2025. Against that, the rate increases since 2024 raised the avoided-cost value of every kilowatt-hour a system produces, and Pennsylvania’s SREC market and net metering rules both remain in place.
The practical question is whether fixing a large share of your electricity cost at today’s price, while utility rates keep moving, works for your household over the next two decades. That is a calculation you can run with your own usage, your own roof and your own utility.

Solar ROI FAQs
What is the average payback period for solar in PA in 2026?
For a cash-purchased system without the federal tax credit, the typical payback period is as early as 10 years, depending on system size, electricity rate, SREC values, and roof orientation. With a lease or PPA there is no payback period in the traditional sense, because there is no upfront cost to recover. Compare projected solar payments plus remaining utility charges with your current bill, including any annual payment increases.
How much can I save with solar in Pennsylvania over 25 years?
A typical residential solar installation in PA can generate $50,000 to $65,000 in cumulative value over 25 years through electricity savings and SREC income, against an initial investment of $24,000 to $28,000. Actual figures depend on system size, utility rates, and SREC market conditions.
Can I still go solar without the federal tax credit?
Yes. The federal residential tax credit is no longer available for homeowner-purchased systems, but Pennsylvania’s SREC program, net metering, and rising utility rates continue to drive strong returns. Lease and PPA options also allow you to benefit from solar with no upfront cost, and the system owner can still access the commercial tax credit through 2027.
What happens to my solar panels if I sell my home?
Owned solar systems transfer with the property and typically increase home value. Studies have consistently shown that homes with solar sell for a premium. Leased systems may require the buyer to assume the lease agreement, which your solar provider can facilitate.
