Introduction
“Is solar worth it?” is the most common question homeowners ask before going solar, and in Pennsylvania in 2026, the answer requires more nuance than it did a year ago.
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 is a meaningful change. But it is far from the only factor that determines whether solar makes financial sense.
Rising electricity rates, Pennsylvania’s SREC program, net metering credits, system cost reductions, and available financing options all play a role in the total return on a solar investment. This guide runs through the real numbers so you can evaluate solar based on facts, not sales pitches.
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 increases improves the value of solar electricity you produce at home
PECO Electricity Rates in 2026: What PA Homeowners Are Actually Paying
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 earn SRECs directly and your total lifetime savings are lower than a cash purchase, but your out-of-pocket risk is essentially zero and you begin saving from month one.
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.
Factors That Improve ROI
High monthly electricity usage means more kWh to offset and more savings. A south-facing roof with minimal shading maximizes production. Being served by a utility with higher rates (PECO, PPL) or steeper projected increases improves the avoided-cost value. Strong SREC market pricing adds income. And a roof in good condition that does not need replacement before installation avoids added project cost.
Factors That Reduce ROI
Significant tree shading on the roof reduces system production. A roof that needs replacement within 5 years adds cost to the project timeline. Low electricity consumption reduces the absolute dollar value of offset power. And homeowners in co-ops or HOA-restricted communities may face installation limitations, though Pennsylvania’s Solar Rights provisions protect most homeowners.
Is Solar Worth It in PA Without the Federal Tax Credit
This is the question of the moment, and the honest answer depends on your financial priorities.
If you are evaluating solar purely as a short-term investment and comparing it to the 2025 numbers that included a 30 percent tax credit, the math is less favorable in 2026. The payback period is longer.
But solar was never a short-term play. The 25-year value proposition remains strong, and in many cases stronger than it was two years ago, because the rate increases that have accelerated since 2024 make the avoided-cost value of solar electricity higher than previous projections assumed.
The question is not whether the federal tax credit would have been nice to have — it would. The question is whether locking in a fixed electricity cost at today’s rates, while utility prices continue to climb, makes financial sense for your household over the next two decades. For most PA homeowners with good roof conditions and meaningful electricity consumption, the answer remains yes.

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 — you typically save from month one with no upfront cost.
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.
