Pennsylvania Solar Incentives 2026: AEC Credits, Federal ITC & Net Metering Guide

Pennsylvania sits at an interesting crossroads in the solar landscape. As the largest electricity consumer in the Northeast, the Keystone State has more solar potential than its reputation suggests — but it also has a more complicated incentive picture than neighboring New Jersey, Maryland, or New York. There is no statewide property tax exemption, no sales tax relief, and no state income tax credit for homeowners. What Pennsylvania does offer is federal tax credit access, a functioning (though less lucrative) Alternative Energy Credit market, legally protected retail-rate net metering, and a sweeping Energy Community ITC bonus that covers a large swath of the state's former coal and manufacturing communities.

This guide covers every Pennsylvania solar incentive available in 2026, the real numbers behind the AEC market, utility-by-utility net metering rules, and full cost-stack examples for Philadelphia and Pittsburgh-area buyers.

Pennsylvania Solar at a Glance

Average system size: 8–10 kW (typical Pennsylvania home) Average installed cost (before incentives): $23,200–$29,000 (at $2.90/W) Peak sun hours/day: 4.0–4.5 (Philadelphia/southeast) to 4.2–4.7 (central PA) to 3.8–4.2 (Pittsburgh/northwest) Average electricity rate: $0.14–$0.18/kWh (PECO highest; West Penn Power/FirstEnergy lower) State AEC/SREC program: Active — currently $25–$50/MWh (Tier 1 solar AECs) Net metering: Retail-rate, PUC-protected Approximate net system cost after all incentives: $14,000–$22,000 (8–10 kW, depending on AEC income) Typical payback period: 9–13 years

1. Federal Solar Investment Tax Credit (ITC) — 30%

Every Pennsylvania homeowner who purchases a solar system qualifies for the federal ITC, which reduces your income tax bill by 30% of the total installed cost — including panels, inverter, racking, wiring, conduit, permitting fees, and labor.

For a typical Pennsylvania system:

System Size	Installed Cost	30% Federal ITC	Net After ITC
7 kW	$20,300	$6,090	$14,210
8 kW	$23,200	$6,960	$16,240
9 kW	$26,100	$7,830	$18,270
10 kW	$29,000	$8,700	$20,300
12 kW	$34,800	$10,440	$24,360

Key ITC rules:

• Claimed on IRS Form 5695 at tax time; no pre-approval or application required
• Locked at 30% through December 31, 2032, then steps down to 26% in 2033 and 22% in 2034
• Unused credit carries forward to future tax years indefinitely — it does not expire
• Cash purchases and solar loans qualify; PPAs and leases do NOT (the financing company captures the credit)
• Pennsylvania's AEC income and other state incentives do NOT reduce your federal ITC calculation

Energy Community Bonus — 40% ITC

If your installation address is in a designated Energy Community — a county or census tract defined by the IRS as formerly dependent on coal, oil, or gas extraction — the ITC increases to 40%, not 30%.

Pennsylvania has extensive Energy Community coverage. Many counties in western, central, and northeastern Pennsylvania qualify based on their coal mining and manufacturing history, including large portions of: Fayette, Greene, Washington, Westmoreland, Cambria, Indiana, Clearfield, Jefferson, Armstrong, Lawrence, Beaver, Butler, Clarion, Elk, and Schuylkill counties, among others.

For an Energy Community buyer with a 9 kW system: $26,100 × 40% = $10,440 federal credit — versus $7,830 at the standard rate. That $2,610 difference is meaningful.

Check your specific address at the Department of Energy's Energy Communities mapping tool before signing a contract.

2. Pennsylvania Alternative Energy Credits (AECs) — Ongoing Income

Pennsylvania's Alternative Energy Portfolio Standards (AEPS) Act, signed in 2004, requires electric distribution companies to source a growing percentage of their power from alternative energy — including a specific Tier 1 solar sub-requirement. To comply, utilities must purchase Solar Alternative Energy Credits (AECs), which are Pennsylvania's version of SRECs.

How Pennsylvania AECs Work

Every time your solar system generates 1,000 kWh (1 MWh) of electricity, it earns one AEC. You can sell these AECs to utilities or on the open market through SREC brokers and aggregators.

Pennsylvania's AEC market is smaller and less lucrative than New Jersey's or Maryland's, for a few reasons:

• Pennsylvania has more in-state solar supply relative to demand than NJ or MD
• The RPS solar sub-requirement has historically been set lower than peer states
• Pennsylvania does not have a mandatory 15-year contract structure like New Jersey's SREC II

Current Pennsylvania AEC prices: approximately $25–$50 per MWh in 2026, with the spot market varying based on how much new solar comes online.

What a Typical Pennsylvania System Earns

A 9 kW system in central Pennsylvania (4.4 peak sun hours/day) produces approximately 11,000–12,000 kWh/year, earning roughly 11–12 AECs annually.

At $35/AEC (midpoint of current range), that is $385–$420/year in AEC income.

Over 15 years, the projected cumulative AEC income for this system is approximately $5,775–$6,300 — meaningful, but roughly half of what a comparable system would earn in New Jersey's SREC II market.

How to participate:

1. Register your system with the PJM-GATS (Generation Attribute Tracking System) or SREC Trade after installation
2. Choose whether to sell AECs spot through a broker, or sign a forward contract for price certainty
3. AECs are issued monthly and can be sold at any time (they expire after 5 years if unsold)

Major AEC brokers active in Pennsylvania include SRECTrade, Sol Systems, and Flett Exchange. Some installation companies offer AEC aggregation services — compare carefully, as fees vary widely.

3. Net Metering in Pennsylvania

Pennsylvania requires all investor-owned utilities to offer net metering to residential solar customers under the Public Utility Commission's rules and the Pennsylvania Public Utility Commission's implementation of Act 129 (2008).

Key net metering rules:

• Rate: Retail rate — when your system produces more than you use, the excess is credited to your bill at the same rate you pay for grid electricity
• Annual true-up: Excess credits carry forward month-to-month. At the end of your net metering anniversary (typically April 30 or your contract anniversary), any remaining surplus is settled — most utilities pay the "avoided cost" rate (approximately $0.04–$0.06/kWh) for any end-of-year surplus, not the full retail rate
• Billing: Monthly billing with credits applied; no monthly cap on credit carryover within the year
• Interconnection: Applications go to your utility; most are approved within 30–60 days for residential systems ≤ 50 kW

Utility-by-Utility Summary

Utility	Service Territory	Notes
PECO (Exelon)	Philadelphia metro + suburbs	Retail-rate net metering; highest rates in PA ($0.16–$0.18/kWh) — strongest economics
PPL Electric	Lehigh Valley, Reading, Harrisburg, Wilkes-Barre	Retail-rate net metering; $0.13–$0.16/kWh
West Penn Power (FirstEnergy)	Pittsburgh suburbs, Allegheny region	Retail-rate; $0.12–$0.14/kWh; lowest generation rates in PA
Penn Power (FirstEnergy)	Lawrence, Mercer, Butler, Crawford counties	Retail-rate; similar rates to West Penn Power
Met-Ed (FirstEnergy)	Reading/Lancaster area	Retail-rate net metering; $0.13–$0.15/kWh
Penelec (FirstEnergy)	Northwest and north-central PA	Retail-rate; smaller territory
PPL (Duquesne Light)	City of Pittsburgh	Retail-rate; $0.13–$0.16/kWh

PECO customers in Philadelphia and its suburbs have the strongest net metering economics in the state — high retail rates mean exported solar electrons are credited at maximum value.

4. Property Tax — No Statewide Exemption

This is the most significant gap in Pennsylvania's solar incentive picture compared to neighboring states.

New Jersey, Maryland, New York, Virginia, and Massachusetts all have statutory property tax exemptions that prevent a solar installation from increasing your assessed property value — and therefore your tax bill. Pennsylvania has no equivalent statewide law.

What that means in practice: if your solar installation increases your home's assessed value, your local property taxes may rise. The actual impact varies by county assessor, and in practice many assessors do not immediately re-assess homes after solar installation — but there is no legal protection against it.

Some Pennsylvania municipalities offer a Local Economic Revitalization Tax Assistance (LERTA) program that can shelter solar improvements from property tax increases for a period of time. Check with your county assessor before installation.

Bottom line: Budget conservatively and do not count on a property tax break when calculating your Pennsylvania solar ROI.

---

5. Sales Tax — No Exemption for Residential Buyers

Pennsylvania does not exempt residential solar installations from the state's 6% sales and use tax (or applicable local rates). You will pay sales tax on solar panels, inverters, racking, and other equipment.

This is another notable gap versus New Jersey (0% sales tax on solar), Maryland (no sales tax on solar), Massachusetts (6.25% exempt), Nevada, Colorado, and most other top solar states.

For a $26,100 system, the 6% Pennsylvania sales tax adds approximately $1,566 to your cost.

One exception: Pennsylvania's sales tax exemption for electricity production equipment applies to commercial and industrial installations. If you are installing a system on a farm or business, consult a tax professional about potential exemption eligibility.

6. Community Solar in Pennsylvania

Pennsylvania enacted a community solar law in 2024 allowing utilities to operate virtual net metering programs for residential subscribers. Implementation is ongoing, and not all utilities have active community solar programs as of 2026.

If you cannot install rooftop solar — because you rent, have a shaded roof, or own a condominium — check with your utility for available community solar subscriptions. PECO in particular has been moving forward with program development. Subscribers typically receive a bill credit for their share of the community solar garden's output, at or near the retail rate.

For renters and condo owners, this remains the only path to solar savings in Pennsylvania until more programs launch. See our community solar guide for how to evaluate subscriptions.

7. Low-Income and Agricultural Programs

Pennsylvania Solar for All: Pennsylvania received substantial IRA funding through EPA's Solar for All program. The state's program provides free or heavily subsidized solar installations for income-qualified households earning up to 200% of the federal poverty level. Contact the Pennsylvania Department of Environmental Protection (DEP) or local community action agencies for current program availability and enrollment.

Weatherization Assistance Program (WAP): Federally funded home energy efficiency program that may include electrical panel upgrades that make solar installation easier. Does not include solar panels directly but can reduce the cost of solar preparation.

USDA Rural Energy for America Program (REAP): Pennsylvania farm owners and rural small businesses can apply for REAP grants covering up to 50% of solar installation costs, plus low-interest loans for the remainder. With the 30% ITC stacking on top, a qualifying rural Pennsylvania farm business can net solar at near-zero cost. The 2024 Farm Bill maintained REAP funding at elevated IRA-era levels. See our solar grants guide for application details.

8. Full Stacking Examples

Example 1: Philadelphia Suburb / PECO Territory, 9 kW System

Item	Amount
Gross installed cost	$26,100
30% Federal ITC	−$7,830
Net cost after ITC	$18,270
Annual electricity bill savings (PECO $0.17/kWh × 11,200 kWh)	~$1,904/year
Annual AEC income (11.2 AECs × $35)	~$392/year
Total annual benefit	~$2,296/year
Simple payback period	~8.0 years
25-year net savings	~$39,000

PECO's high rates make Philadelphia-area buyers among the best-positioned in the state. No property tax or sales tax exemption applies in this example.

Example 2: Pittsburgh Area / West Penn Power Territory, 9 kW System (Energy Community)

West Penn Power territory in Allegheny and surrounding counties has lower electricity rates than PECO, but many zip codes qualify for the 40% Energy Community ITC bonus.

Item	Amount
Gross installed cost	$26,100
40% Energy Community ITC	−$10,440
Net cost after ITC	$15,660
Annual electricity bill savings (West Penn $0.13/kWh × 10,800 kWh)	~$1,404/year
Annual AEC income (10.8 AECs × $35)	~$378/year
Total annual benefit	~$1,782/year
Simple payback period	~8.8 years
25-year net savings	~$29,000

The 40% Energy Community bonus nearly eliminates the rate disadvantage vs. PECO territory — Pittsburgh-area buyers in qualifying counties can achieve similar payback periods to Philadelphia buyers despite lower electricity rates.

9. Pennsylvania vs. Neighboring State Comparison

State	State Credit	SREC/AEC Market	Property Tax Exempt?	Sales Tax Exempt?	Avg Payback
Pennsylvania	None	Yes ($25–50/MWh)	No (no statewide law)	No	8–13 years
New Jersey	None	Yes ($185–270/MWh, SREC II)	Yes (100%)	Yes (full)	4–5 years
Maryland	None	Yes ($60–90/MWh)	Yes (100%)	Yes (full)	6–9 years
New York	25% (max $5K)	No	Yes	Yes (full)	7–10 years
Virginia	None (expired)	No	Yes (100%)	Partial	10–11 years

Pennsylvania is the weakest of its immediate neighbors for solar incentives. The federal ITC and AEC income are real — but the absence of a property tax exemption, sales tax relief, and a robust SREC market means total lifetime savings are lower than comparable systems next door in New Jersey or Maryland.

If you live near a state border, it is worth understanding how incentives compare — especially if New Jersey is accessible (NJ's SREC II program pays 4–6× more per MWh than PA's AEC market).

10. Is Solar Worth It in Pennsylvania in 2026?

Despite the incentive gaps compared to neighboring states, solar makes financial sense for many Pennsylvania homeowners — especially:

• PECO customers in Philadelphia and suburbs (high rates, good sun, 8-year payback achievable)
• PPL customers in Lehigh Valley, central PA (good rates, central PA sun hours)
• Energy Community buyers in western PA qualifying for 40% ITC (partially offsets lower rates)
• Agricultural/rural properties eligible for USDA REAP (50% grant stacks with 40% ITC)

Solar is harder to justify on financial terms alone for:

• West Penn Power / Penelec customers in low-rate territories with no Energy Community bonus
• Buyers who plan to sell their home within 7–8 years (payback period may not be reached)
• Homes with significant shading or north-facing roof planes

The AEC income and federal ITC together still provide a meaningful incentive stack. Pennsylvania solar buyers just need to enter the math with realistic expectations — this is not a New Jersey situation where the economics are near-exceptional.

How to Get Started in Pennsylvania

1. Get 3+ quotes from Pennsylvania-licensed solar installers — never accept the first offer
2. Check your Energy Community status at energycommunities.gov before finalizing a contract
3. Ask each installer about AEC enrollment — find out whether they handle PJM-GATS registration or whether you need to set up an SREC broker relationship separately
4. Verify your utility's current net metering tariff — rules can change, and what a sales rep tells you verbally should be confirmed in writing
5. Review interconnection timelines — PECO in particular has had longer-than-average interconnection queues in recent years; factor 3–6 months into your timeline

See our solar installation timeline guide for a full breakdown of what happens between contract signing and your system going live, and our best solar companies guide for what to look for when vetting installers.
