It depends on your utility. At PECO rates ($0.21/kWh) with PA SRECs ($22–$35/MWh), payback is 11–13 years. At Duquesne Light ($0.18/kWh), closer to 14–16 years. PA has no federal ITC, no state rebate, no property tax exemption, and charges 6% sales tax on solar — but net metering and SRECs still make it work in most of the state.
Federal 25D residential solar tax credit: EXPIRED Dec 31, 2025. PA homeowners get $0 federal credit on cash/loan purchases. This guide reflects 2026 no-credit reality.
Using a typical 8 kW system at $3.10/W — the average for Pennsylvania in 2026.
Then ~25 years of free electricity. System warranted for 25–30 years.
We don't sugarcoat it. Pennsylvania has more solar headwinds than most neighboring states.
Section 25D expired December 31, 2025 under the One Big Beautiful Budget Act. PA homeowners buying solar cash or loan get $0 federal credit — unlike neighboring NJ, MD, or DE. This adds 3-4 years to payback vs. pre-2026.
Pennsylvania charges 6% sales tax on solar panels, inverters, and other equipment. On a $24,800 system, that's $1,488 added to your cost. PA is one of only ~12 states that doesn't exempt solar from sales tax.
Unlike NJ, NY, MA, CT, and most neighboring states, PA has no solar property tax exemption. Solar panels ADD to your assessed value — raising your property tax bill by an estimated $200-500/year depending on county.
PA SRECs trade at only $22-35/SREC (1 SREC = 1 MWh), far below NJ's $85.00/MWh. This is because PA's solar carve-out is just 0.5% — the lowest in the region. The PRESS Act could fix this, but it's pending.
PPL Electric Utilities has proposed replacing 1:1 retail net metering credits with hourly wholesale (LMP) rates (~July 2026). If approved, PPL customers installed after that date could see dramatically lower savings. Lock in now.
The headwinds are real — but so is the value stack. Here's what still makes solar viable.
PA law requires 1:1 full retail credit monthly. At PECO's $0.21/kWh, an 8 kW system earns ~$1,680-2,016/year in avoided costs — the primary value driver for PA solar despite the lack of incentives.
An 8 kW eastern PA system generates ~9-10 SRECs/year, earning $230-350/year. Over 25 years, that's $5,750-8,750. Not game-changing, but adds meaningful revenue on top of net metering.
Third-party solar companies claim the 30% Section 48/48E commercial ITC and pass the savings as lower rates. PA homeowners who can't use 25D (everyone, now) may actually prefer PPA over cash purchase.
Pennsylvania Treasury's Keystone Home Energy Loan Program offers low-interest financing for energy improvements including solar. Check current rates at PHFA.
PA is deregulated — you can shop supply rates. Strategic rate shopping combined with solar self-supply is a powerful combination to minimize energy costs.
HB 501 / PRESS Act would raise PA's solar carve-out from 0.5% to 5.5%, likely boosting SREC values from $28 to $85+/SREC. Systems installed today benefit if/when this passes.
Your utility territory is the single biggest factor in whether solar makes sense in PA.
| Utility | Rate/kWh | Sun Hours | Net Metering | Payback (8 kW) | Verdict |
|---|---|---|---|---|---|
PECO Philadelphia + SE suburbs | $0.21 | 4.5–4.9 PSH | 1:1 retail (monthly) | 11–13 yrs | Best economics in PA |
PPL Electric Lehigh Valley, Harrisburg, Scranton | $0.19 | 4.0–4.5 PSH | 1:1 retail — AT RISK Hourly LMP change proposed July 2026 | 12–14 yrs | Install before July 2026 |
Met-Ed (FirstEnergy) Berks, Lebanon counties (Reading) | $0.20 | 4.2–4.6 PSH | 1:1 retail (monthly) | 12–14 yrs | Solid economics |
Duquesne Light Pittsburgh metro | $0.18 | 3.5–4.0 PSH | 1:1 retail (monthly) | 14–16 yrs | Lower production + rate |
Penelec (FirstEnergy) Erie, northwest PA | $0.19 | 3.5–3.8 PSH | 1:1 retail (monthly) Low sun hours (Erie effect) | 15–17 yrs | Lowest production in PA |
Payback based on 8 kW system at $3.10/W + 6% PA sales tax ($26,288 total), 1:1 net metering, and $28/SREC avg income.
HB 501 — the Pennsylvania Renewable Energy Standard Strengthening (PRESS) Act — is pending in the PA legislature. If passed, it would raise the state's solar carve-out from 0.5% to 5.5%, dramatically increasing demand for PA SRECs and likely pushing SREC prices from $22–$35 to $85+ per SREC — approaching NJ's $85.00/MWh rate.
PRESS Act is pending — not guaranteed. Systems installed today automatically receive higher SREC income if/when it passes.
With no federal ITC available, the gap between cash purchase and PPA/lease has narrowed. Here's how each option stacks up in 2026.
Best for: Homeowners with available capital, maximizing long-term ROI
Best for: Preserving cash — but verify your rate savings > loan payment
Best for: Renters, those who can't use tax credits, or prefer no maintenance
We want to give you the business, but only if solar truly makes sense for you. Here are situations where we'd recommend against it — or advise waiting.
Your roof is less than 10 years old and will need replacement within 5 years
You live in Erie or northwest PA (lowest sun hours in state — 3.5 PSH average)
You're in Penelec territory with both low rates AND low production
Your electricity usage is under 4,000 kWh/year (system too small to justify fixed costs)
You're planning to sell your home in under 5 years
You have significant tree shading with no viable ground mount option
Your HOA prohibits solar and PA's SB 826 (Solar Access Act) hasn't passed

It depends on your utility. In PECO territory (Philadelphia area), an 8 kW system costs $26,288 after 6% sales tax with no federal credit. Net metering at $0.21/kWh + SRECs ($22-35/MWh) produces $1,800-2,200/year in savings, delivering an 11-13 year payback. Duquesne territory (Pittsburgh) faces both lower rates ($0.18/kWh) and lower sun hours (3.5 PSH), pushing payback to 14-16 years. Solar is worth it in PA — but the economics are tighter than pre-2026 without the federal ITC.
Yes. Pennsylvania charges 6% sales tax on solar equipment (panels, inverters, racking). Unlike Massachusetts, New Jersey, Maryland, and most neighboring states, PA has no sales tax exemption for solar. On a $24,800 system, that adds $1,488. This is one of PA's biggest solar disadvantages.
No. Pennsylvania has no solar property tax exemption. Installing solar panels increases your home's assessed value, which raises your property tax bill. This is the opposite of NJ, NY, MA, CT, and most mid-Atlantic states that exempt solar from property taxes. Budget $200-500/year in additional property taxes depending on your county assessment rate.
Without the federal tax credit: PECO territory (SE PA): 11-13 years | PPL territory (Lehigh Valley, Harrisburg): 12-14 years | Duquesne territory (Pittsburgh): 14-16 years | Erie / Penelec territory: 15-17 years. The payback was 7-9 years when the 30% ITC was available. The expiration of 25D added roughly 3-4 years to payback in PA.
SRECs (Solar Renewable Energy Credits) are certificates representing 1 megawatt-hour of solar generation, traded via PJM-GATS. PA SRECs trade at $22-35 per SREC — the lowest in the region, because PA's solar carve-out is only 0.5% under Act 213/Act 35. An 8 kW system generates ~9 SRECs/year, earning $200-315/year. The PRESS Act (HB 501) is pending in the PA legislature and would raise the carve-out to 5.5%, potentially boosting SREC values to $85+.
The Pennsylvania Renewable Energy Standard Strengthening (PRESS) Act (HB 501) is pending legislation that would raise PA's solar carve-out from 0.5% to 5.5% under the Alternative Energy Portfolio Standard. If passed, this would dramatically increase demand for PA SRECs and likely raise prices from $22-35 to $85+ per SREC — similar to New Jersey's SREC-II program values. Systems installed today would benefit from higher SREC income if and when PRESS passes.
PPAs and leases are worth serious consideration in PA for 2026. Since homeowners get $0 from the expired federal ITC, the gap between buying and leasing has narrowed. Third-party owners (PPA companies) still claim the 30% Section 48/48E commercial ITC and pass savings as lower rates. A PPA typically saves $400-900/year with $0 down. You won't own the system or earn SRECs, but you also avoid the 6% sales tax hit and property tax increase. Best for: low-to-moderate electricity users who don't have capital for a cash purchase.
PA requires 1:1 full retail rate net metering monthly. Excess solar production rolls as bill credits at your full rate (e.g., $0.21/kWh for PECO). At year-end, any remaining credits are paid at the Price-to-Compare (PTC) rate — the supply-only rate, roughly $0.11-0.13/kWh. This means you want to right-size your system to consume most production rather than overproduce. Caution: PPL Electric has proposed replacing 1:1 retail credits with hourly wholesale rates as early as July 2026.
