Pennsylvania Solar: Credits, a May 31 Payout and SRECs

Written by Dean Mahmoud, CEO, and checked by Trevor Guilday, founder.Prices from the September 2026 Cost Index. Updated October 19, 2026.

A typical Pennsylvania home system is 8.26 kW and costs about $23,706 in cash at $2.87 per watt. If your utility sells you power, each kWh you send out earns a full bill credit: simple payback before incentives is 10.8 years statewide in our per-utility figures, 10.6 to 10.7 years at FirstEnergy Pennsylvania, the largest utility, and 11.4 years at PECO. With a competitive supplier, PECO credits only its 10.236¢ delivery charge: 16.3 years in our case.

Utility or supplier: who sells your power sets your Pennsylvania credit

Pennsylvania lets you choose who sells you power. Under the state’s net metering rule, that choice changes what each kWh you send to the grid is worth.

Your utility sells your power full price

  1. Power you use as it is made lowers your bill.
  2. Each kWh you send out earns a credit at the full price, delivery included.
  3. Extra credits roll forward to May 31, then pay out at the price to compare.

A competitive supplier sells it 10.236¢ at PECO

  1. Power you use as it is made still saves your full price.
  2. Your utility credits each kWh you send out at its delivery charge only.
  3. Leftover delivery credits are zeroed out at year end. Any credit for the power itself must be in your supplier contract.

How we calculated this
  • Output: 8.26 kW × 1,399 kWh per kW (PVWatts, Philadelphia) = 11,556 kWh a year. 40% is used at home as it is made (4,622 kWh) and 60% is sent out (6,934 kWh).
  • PECO case, from our per-utility figures of October 30, 2026: all 11,556 kWh are worth 18.003¢, PECO’s EIA average of 19.494¢ for September 2025 to August 2026 less its $11.33 in fixed monthly charges. That is $2,080, and $23,706 ÷ $2,080 = 11.4 years before incentives, with no upkeep or price rises.
  • Supplier case, ours: 4,622 kWh × 20.86¢ (the EIA state average, 12 months to August 2026), plus 6,934 kWh × 10.236¢, PECO’s Rate R distribution charge from July 1, 2026. That is $1,674. We assume the supplier contract pays nothing for the power itself.
  • Supplier case only: upkeep of $30 per kW a year, $247.80, including an inverter reserve, and payback = ($23,706 − $500 PECO rebate) ÷ (savings − upkeep). No financing, rate changes, panel aging or SREC income.
  • Other utilities in our per-utility figures, before incentives: PPL 11.2 years, Duquesne Light 8.8, FirstEnergy Pennsylvania 10.6 to 10.7 across Met-Ed, Penelec, Penn Power and West Penn, UGI 10.8, Pike County 9.2, Wellsboro 10.6 and Citizens’ 12.6. Weighted by customers, Pennsylvania comes to 10.8 years. Co-ops have no figure; ask yours.
  • 20.86¢ includes fixed charges, so it can run high. A PPL home with a supplier would earn 6.175¢ on power sent out; we did not model that case.

PECO, PPL, FirstEnergy or Duquesne Light: what your utility adds

All four give the same full credit to homes that buy power from them. What differs is the cash extra, the year-end payout price and the credit if you shop for power.

PECO

$500 solar rebate

Philadelphia and the counties around it. Once per home. Battery pay: $80 per kW each season through Flex & Save.

Next: send the rebate form within 90 days of in-service status.

PPL Electric Utilities

$150 per kW of battery, each season

Central and eastern Pennsylvania. Up to $400 a season. PPL listed no rebate for solar panels when we checked.

Next: check your battery is on PPL’s list. When we checked, it named SolarEdge (with SolarEdge or LG batteries) and Enphase IQ Batteries.

FirstEnergy Pennsylvania

Not open yet

Met-Ed, Penelec, Penn Power and West Penn Power. The regulator approved a plan with a solar measure for homes on March 12, 2026. No amount or way to apply yet.

Next: do not let a quote count a FirstEnergy rebate.

About these prices, and co-ops or borough utilities

The year-end payout is the price to compare, for June 1 to November 30, 2026; it resets December 1. At PECO it is 10.785¢ for generation plus 0.974¢ for transmission. PPL’s and Duquesne Light’s figure is printed on your bill. Their tariffs, read October 19, 2026, list PPL’s residential generation supply charge at 9.753¢ and transmission charge at 3.326¢ per kWh, with a 1.80% merchant function charge, and Duquesne’s default supply at 10.9568¢ (June 1 to November 30, 2026) and transmission at 3.1841¢ per kWh. The supplier credit is the utility’s distribution charge: PECO Rate R from July 1, 2026, PPL Rate RS from October 1, 2026.

Duquesne Light serves the Pittsburgh area. We found no solar rebate or battery payment there; ask in writing. Rural electric co-ops and borough utilities are outside the state credit rule, so ask yours what each kWh you send out earns, whether credits roll over and what happens at year end.

What Pennsylvania does with leftover credits on May 31

Credits you do not use roll forward at full value through the credit year. On May 31, what is left pays out at a lower price, so size the system to a year of your own use. Worked example by utility: Pennsylvania net metering explained.

June 1Credit year starts

It runs June 1 through May 31. Extra kWh carry forward from month to month until then.

11.759¢PECO year-end payout

Leftover kWh are paid at the price to compare. 100 leftover kWh pay $11.76.

$0Supplier leftovers

If a supplier sells your power, unused delivery credits are zeroed out at year end.

50 kWSize limit

For home systems at the four large utilities. A PECO lease may make no more than 110% of your yearly use.

What an 8.26 kW Pennsylvania system costs at $2.87 per watt

The September 2026 benchmark, $0.02 below the US average. These are modeled cash prices, not quotes we collected.

How we got these numbers
  • 8.26 kW is the median size Pennsylvania homeowners installed in 2025 (Berkeley Lab, 1,199 systems). Size yours to a year of your own use.
  • Output uses 1,399 kWh per kW a year (PVWatts, Philadelphia), the figure in our payback cases. Shade lowers it.
  • A system you own gets no federal tax credit after December 31, 2025.

Program term through May 31, 2031, while funds last. Form due within 90 days of in-service status.

$150/kWPPL battery pay

Each season, up to $400. PECO pays $80 per kW each season; its example comes to $480 a year.

$0Tax credits

Programs you may hear about that pay nothing today
  • Pennsylvania Solar for All: the state agency says it is “not operational at this time” and tells homeowners to ignore installers that claim to be its partners.
  • A FirstEnergy solar rebate: approved in a plan on March 12, 2026, but there is nothing to apply for yet.
  • Solarize Greater Philadelphia: help, not money. It offers checked installers in Bucks, Chester, Delaware, Montgomery and Philadelphia counties, with a workmanship warranty of at least 10 years, and a no-upfront-cost lease for household incomes up to $165,000.
  • Property tax relief: do not count on it. Ask your county assessment office in writing how it values a home with solar.

Six things a Pennsylvania solar contract should show

The first three come from Pennsylvania’s Home Improvement Consumer Protection Act, which names solar energy systems. The last three are the lines that move your payback.

  • A registration numberA home improvement contract cannot be enforced against you without the contractor’s state registration number. Look it up in the Attorney General’s contractor search.
  • Three business days to cancelThe contract must include a notice that you can cancel without penalty within three business days of signing.
  • A deposit of one-third or lessOn contracts over $5,000, the deposit is capped at one-third of the price, plus special-order materials listed in the contract. Some large retailers are exempt.
  • Who sells your powerThe credit behind the savings: the full price if your utility sells your power, or the delivery charge if a supplier does.
  • Size against a year of useYear-one kWh next to your last 12 months of bills, so little is left for the May 31 payout.
  • SRECs, rebate and taxWho owns and registers the SRECs, who files the PECO rebate form, sales tax inside the contract price rather than added on top, and no federal credit subtracted.

Pennsylvania Solar FAQs

Does Pennsylvania have net metering?

Yes. Under 52 Pa. Code 75.13, PECO, PPL, FirstEnergy and Duquesne Light credit each kWh you send out at the full retail price, including delivery, for home systems up to 50 kW, if you buy your power from them. Credits left on May 31 are paid at the lower price to compare.

What changes if I buy power from a competitive supplier?

Your utility credits only its distribution charge for each kWh: 10.236¢ at PECO and 6.175¢ at PPL in October 2026. Delivery credits left at year end are zeroed out. Any credit for the power itself must be written in your supplier contract, so ask the supplier before you sign for solar.

Is there a solar tax credit in Pennsylvania?

No. The state’s list of personal income tax credits has no solar credit, and the federal homeowner credit ended for systems placed in service after December 31, 2025. A quote that still subtracts 30% is wrong.

Are Pennsylvania SRECs worth selling?

They add a little. A typical 8.26 kW system earns about 11.6 credits a year, or about $327 at the 2025/26 average of $28.26, before broker fees. Prices ran from $4 to $81, so we leave SRECs out of the payback.

Do I pay sales tax on solar in Pennsylvania?

Yes, inside the price. The state rate is 6%, plus 2% in Philadelphia and 1% in Allegheny County, and the Department of Revenue says home solar panels do not qualify for the exemption for making electricity. In an installed contract the installer pays it on the materials and equipment it installs, so it reaches you inside the contract price, not as a separate line (61 Pa. Code 31.12). The sources behind our $2.87 per watt benchmark do not say whether sales tax is included.
