Solar Panels in Pennsylvania (2026): The Honest Numbers

Pennsylvania is the hardest sell of the mid-Atlantic solar states, and we'd rather say that up front than bury it.

No state tax credit. No statewide rebate. No sales tax exemption — you pay 6% on the whole system. And no property tax exemption — the value solar adds to your home can raise your assessment. Maryland, New Jersey, and Massachusetts all shield you from at least some of that. Pennsylvania doesn't.

It can still work, mostly because electricity here is getting expensive fast. But the math is tighter than most Pennsylvania solar pages admit — and several of them list tax exemptions this state does not have.

The Short Answer

• Typical installed cost: about $2.55–$3.20 per watt. The average Pennsylvania system is roughly 13.3 kW — about $34,000 (range $28,900–$39,200).
• You pay 6% sales tax on the system. Roughly $2,000 on an average install.
• Your property taxes may go up. Pennsylvania doesn't exempt the added value.
• The 30% federal credit is gone for cash and loan buyers.
• What's left: 1:1 retail net metering (genuinely good), a modest SREC market (~$22/credit), and rising utility rates.
• Realistic payback: roughly 10–12 years once you count the property tax drag.

The Two Things Pennsylvania Doesn't Have (That Sites Say It Does)

No property tax exemption

In most solar states, adding panels raises your home's value without raising your tax bill — the added value is legally excluded from your assessment. New Jersey does it. Maryland does it. Massachusetts does it for 20 years.

Pennsylvania does not. When solar increases your home's assessed value, that value is included in your property tax assessment.

This is a real, recurring cost that essentially no payback calculator includes. If solar adds ~$15,000 in assessed value at a ~1.5% effective rate, that's roughly $225/year working against your savings — about $5,600 over 25 years. It won't kill the deal. But leaving it out of the math isn't honest, so we've put it in ours below.

No sales tax exemption

Pennsylvania's 6% sales tax applies to solar panels and equipment, plus any local sales tax. On a $34,000 system that's about $2,000 — money a Maryland homeowner simply doesn't pay.

Ask whether your quote includes sales tax. A quote that excludes it is understating your real cost by around two grand.

What some sites claim instead

Researching this page in July 2026, we found active Pennsylvania pages listing "property tax exemptions, and sales tax exemptions" as available state incentives, and one running its entire payback model on "the 30% federal ITC, retail-rate net metering, property tax exemption, and SREC income" — producing a cheerful 7.5–9.5 year payback built on two things that don't exist and one that expired.

Another states that "All US homeowners qualify for the 30% federal ITC through 2032" and prices a 9 kW system at "$18,900 after 30% ITC."

If your proposal shows a federal credit, a PA sales tax exemption, or a PA property tax exemption, the numbers are wrong. See our 2026 tax credit guide.

Why Solar Still Works Here: The Rates

Pennsylvania homeowners pay about 21¢/kWh in 2026 — and the direction is what matters:

• PECO (Philadelphia area): ~23–24¢/kWh all-in — up about 16.7% in a year
• PPL, Met-Ed, Penelec: ~20–21¢/kWh all-in
• Duquesne Light (Pittsburgh area): in the same broad band

The driver isn't local. The PJM capacity market cost surge is hitting the whole region — PPL, Met-Ed, Penelec and West Penn Power customers are all seeing similar increases, and some New Jersey utilities saw 17–20% bill hikes. Southeastern Pennsylvania is taking a particular concentration of it.

That's the Pennsylvania case in one line: you're not betting on incentives, you're hedging against your utility. Your panels' cost is fixed the day you buy them. PECO's isn't.

Net Metering — the Best Thing Pennsylvania Has

The PUC requires every investor-owned utility — PECO, PPL, Met-Ed, Penelec, West Penn Power, Duquesne Light — to offer 1:1 net metering at the full retail rate for residential systems up to 50 kW. Credits roll month to month and true up annually, with excess paid at the lower "price to compare" rate.

Two things to know:

• Municipal utilities and rural electric co-ops aren't required to offer it. Check your bill before anything else.
• If you buy power from a third-party supplier, consider switching back to your utility. Utilities must provide net metering credits; competitive suppliers don't have to. This catches people out and it's easy to fix before you install.

One live item worth watching: at least one installer reports proposed tariff changes in PPL territory around July 2026 that could affect net metering terms. We could not confirm this against a PUC docket, so treat it as unverified — but if you're a PPL customer, it's worth asking your installer directly.

SRECs — Real, but Small

You earn one SREC per megawatt-hour. A typical home system produces 9–12 a year.

Pennsylvania SRECs trade around $22 at spot, with brokers quoting ranges from roughly $22 to $50 depending on contract type. Call it a few hundred dollars a year — useful, not decisive.

Why so cheap? Pennsylvania's solar carve-out under the Alternative Energy Portfolio Standard is 0.5% of electricity sales — it hit that maximum in 2021 and hasn't moved in over a decade. Maryland, New Jersey and DC raise their requirements over time; Pennsylvania doesn't. That's the whole explanation. DC SRECs trade north of $380; Pennsylvania's trade at $22 for exactly this reason.

Act 40 in 2017 at least restricted eligibility to systems physically located in Pennsylvania, which cut oversupply and stabilized prices. And proposed legislation (PRESS) could raise the requirement — but don't model your payback on a bill that hasn't passed.

Practical notes: PA SRECs have a 3-year shelf life, so they expire if you sit on them. Systems over 15 kW need revenue-grade metering. And under a lease or PPA, the SRECs belong to the company, not you.

What Solar Actually Costs in Pennsylvania

• 6 kW system: ~$15,300–$19,200
• 8 kW system: ~$20,400–$25,600
• 13.3 kW (PA average): ~$34,000 (range $28,900–$39,200)

EnergySage marketplace data puts Pennsylvania at $2.55/W as of July 2026; installers quote $2.70–$3.20/W depending on region. Confirm whether sales tax is included.

Where you live changes this a lot — more than in most states:

• Philadelphia / southeastern PA: best sun in the state (~4.5–4.9 peak sun hours) and the highest rates. Best economics in Pennsylvania.
• Lancaster / Reading: lowest installed costs (~$2.70–$3.10/W), large rural rooftops.
• Pittsburgh: lower sun (~3.5–4.0 PSH), partially offset by lower labor costs.
• Erie: worst solar economics in the state — lake-effect cloud cover cuts production to roughly 1,000 kWh per kW, with the lowest rates to offset. If you're in Erie, be skeptical.

Compare quotes on cost per watt, not the headline total — our quote comparison tool does the math. Not included: panel upgrades ($1,200–$2,000), roof work, or a battery ($10,000–$15,000 — see our battery guide).

The Payback Math, Shown in Full — Including the Property Tax Nobody Counts

Our calculations from the sourced figures above — not a quote, and not a promise about your home.

Assumptions: 8 kW at $2.85/W = $22,800 installed including PA sales tax; production ~1,200 kWh per kW = ~9,600 kWh/year; electricity offset at $0.21/kWh; 9.6 SRECs at $22; property tax on ~$15,000 added assessed value at a ~1.5% effective rate.

• System cost (no federal credit, no state credit, no rebate): $22,800
• Electricity avoided (9,600 × $0.21): $2,016/yr
• SREC income (9.6 × $22, pre-tax): ~$211/yr
• Less added property tax: –$225/yr
• Net annual benefit: ~$2,002/yr

Simple payback: $22,800 ÷ $2,002 ≈ 11.4 years.

Leave the property tax out — as nearly every Pennsylvania calculator does — and you'd get 10.2 years. That one line is worth more than a year of payback, and it's the line that gets skipped.

We also didn't apply rate escalation. With PECO up 16.7% in a year and PJM capacity costs climbing, a real model would land shorter. We left it flat deliberately — escalation assumptions are where optimistic savings claims get manufactured.

What moves it down (better): PECO territory, high usage, south-facing unshaded roof, the Philadelphia rebate, higher SREC prices if PRESS passes. What moves it up (worse): Erie or western PA, shading, low usage, a co-op that doesn't net meter, a quote that excluded sales tax.

Local Programs Worth Checking

• Philadelphia Solar Rebate — reported at $0.20/W for residential systems inside city limits (about $1,200 on a 6 kW system). It's been reported as running on a waitlist, so confirm current funding and availability with the city rather than assuming.
• HEELP loans — 1% financing through the Pennsylvania Housing Finance Agency for qualifying energy improvements.
• Third-party ownership — with 25D gone, a lease or PPA is now how most Pennsylvania homeowners capture any federal value, since the installer claims 48E and prices it into your rate. The tradeoff is real: you give up your SRECs, which in PA is a smaller loss than in Maryland. Run both. See our financing guide.

When Solar Does Not Make Sense in Pennsylvania

We generate leads for solar companies. Pennsylvania is where we're most likely to tell you no:

• Your bill is under about $130/month. No credit, no rebate, no exemptions, sales tax on top. Small systems don't clear.
• You're in Erie or lake-effect country. ~1,000 kWh/kW and the state's lowest rates is a bad combination.
• You're moving within 7 years. An 11-year payback doesn't survive that.
• Shaded or east/west roof. Pennsylvania has less sun to give away than Virginia or Maryland.
• You're on a co-op or municipal utility without retail net metering. This is the single biggest check to run first.
• Your roof needs replacing soon. Do the roof first, always.

If you're a PECO or PPL customer with a south-facing roof and a $150+ bill, Pennsylvania works — on the strength of net metering and a utility rate that keeps climbing, not on incentives.

Frequently Asked Questions

Does Pennsylvania have a solar property tax exemption?
No. Unlike most solar states, Pennsylvania includes the added value of your system in your property assessment, so your tax bill can rise. Several sites incorrectly list one.

Do you pay sales tax on solar panels in Pennsylvania?
Yes — the 6% state sales tax plus any local tax applies. That's roughly $2,000 on an average system.

Is the 30% federal solar tax credit still available in Pennsylvania in 2026?
No. Section 25D ended for systems placed in service after December 31, 2025. Section 48E survives but goes to the system owner — in a lease or PPA, that's the company.

How much do solar panels cost in Pennsylvania in 2026?
About $2.55–$3.20 per watt. The average system is roughly 13.3 kW (~$34,000, range $28,900–$39,200). An 8 kW system runs ~$20,400–$25,600, plus sales tax if not included.

How much are Pennsylvania SRECs worth in 2026?
Around $22/MWh at spot, with quoted ranges of ~$22–$50. A home system earns 9–12 a year. PA's carve-out has been capped at 0.5% since 2021, which is why prices trail Maryland, NJ and DC.

Does Pennsylvania have net metering?
Yes — 1:1 retail rate for residential systems up to 50 kW, required of all investor-owned utilities. Municipal utilities and co-ops aren't covered. If you use a third-party supplier, consider switching back to your utility, since suppliers aren't required to provide credits.

What is the solar payback period in Pennsylvania in 2026?
Roughly 10–12 years for a cash purchase once you include the property tax increase Pennsylvania doesn't exempt. Rising rates carry the math, not incentives.

Is there a solar rebate in Philadelphia?
Philadelphia has run a $0.20/W rebate (~$1,200 on 6 kW), reported as operating on a waitlist. Confirm current availability with the city. There's no statewide rebate.
