Both Section 25D and 25C are dead. Pennsylvania homeowners get zero federal tax credits on cash/loan solar and heat pump purchases. But SRECs, 1:1 net metering, Act 129 utility rebates, and Section 30C (EV charger) still make whole-home electrification viable — if you understand the real numbers.
Federal Tax Credits: Both DEAD
Section 25D (solar ITC) and Section 25C (heat pump credit) both expired December 31, 2025. $0 federal benefit for cash/loan purchases. Section 30C (EV charger) alive until June 30, 2026. Third-party PPA/lease can access Section 48E (30%) for the solar component only.

30C EV Credit
Two federal tax credits that previously made solar and heat pump purchases affordable expired at the end of 2025. This is not speculation — it is law.
Expired December 31, 2025. Zero federal tax credit on cash/loan solar purchases. Was 30% ($7,200 on $24K system).
Expired December 31, 2025. Zero federal credit for heat pumps, insulation, or energy efficiency improvements. Was up to $2,000/year.
What this means for PA homeowners: A $24,000 solar system that would have received a $7,200 ITC refund now costs the full $24,000. A $12,500 heat pump that would have received a $2,000 25C credit now costs the full $12,500. Combined, you lose $9,200 in federal benefits compared to 2025. Every dollar of savings must now come from state programs, utility rebates, and operational savings.
Federal credits are dead, but Pennsylvania has a strong set of state and utility incentives. Here is every available benefit for whole-home electrification in 2026.
15+ years
PA AEPS solar carve-out generates SRECs worth $22-$35/MWh. A 12 kW system produces ~13 SRECs/year = $286-$455 annually. Over 15 years: $4,290-$6,825.

PA Sales Tax Warning
Pennsylvania charges 6% sales tax on solar equipment (approximately $1,320-$1,560 on a 12 kW system). There is no sales tax exemption for solar in PA — unlike NJ, CT, MA, and most neighboring states. This is an added cost unique to PA that must be factored into your ROI.
Pennsylvania is a gas-producing state with relatively cheap natural gas. Unlike New England where oil-to-HP conversions save $1,000+/year, PA gas-to-HP savings are narrow. Here is the honest math.
Gas-to-HP Savings: Only $440/Year
$1,300 (gas) minus $860 (heat pump) = $440/year in fuel switching savings. On its own, a $12,500 heat pump would take 28+ years to pay back from fuel savings alone. The key is pairing it with solar: net metering covers the heat pump electricity cost ($860/yr), effectively making the HP heating free once solar is producing. Combined solar + HP ROI is dramatically better than either alone.
| Fuel Being Replaced | Annual Cost | HP Cost | Annual Savings | With Solar Offset |
|---|---|---|---|---|
| Natural Gas | $1,300/yr | $860/yr | $440/yr | $1,300/yr |
| Heating Oil | $2,300/yr | $860/yr | $1,440/yr | $2,300/yr |
| Propane | $2,100/yr | $860/yr | $1,240/yr | $2,100/yr |
"With Solar Offset" = total fuel bill eliminated when solar covers both base electric and heat pump demand via net metering.
Here is the full cost breakdown for a typical PA whole-home electrification bundle in 2026.
PA avg $2.95-$3.15/W. 6% sales tax adds ~$1,400. No property tax exemption.

PRESS Act Upside
The PRESS Act (PA Renewable Energy Standard Strengthening) is pending in the PA legislature. If passed, it would raise the solar carve-out from 0.5% to 5.5%, dramatically increasing demand for SRECs and likely boosting prices well above $35/MWh. Systems installed now would benefit from the price increase retroactively.
SRECs Require Ownership
You only earn SREC income if you own your solar system (cash purchase or loan). PPA and lease customers forfeit SRECs to the third-party system owner. Over 15 years, this means giving up $4,290-$7,350 in income.
Homeowners cannot claim the solar ITC. But third-party financing companies can claim Section 48E (30% commercial ITC) on systems they own and lease to you. The benefit flows through as a lower monthly PPA or lease rate.
| Financing | Solar Cost | Federal Credit | SREC Income | Monthly Payment | Best For |
|---|---|---|---|---|---|
| Cash Purchase | $24,000 | $0 | You keep (~$350/yr) | $0 (paid upfront) | Maximum long-term ROI, SREC income |
| Solar Loan | $24,000 | $0 | You keep (~$350/yr) | $220-$280/mo (6-8% APR, 15yr) | Ownership with lower upfront cost |
| PPA / Lease (Section 48E) | $0 down | 30% to financing company | Financing company keeps | $120-$160/mo PPA rate | $0 down, lower monthly than utility bill |
Section 48E Deadline: The third-party system owner must begin construction before July 4, 2026 to claim the 30% ITC. After that date, new PPA/lease agreements will not include ITC benefits, and monthly rates will increase accordingly.
Section 30C is the last surviving residential clean energy tax credit. It covers 30% of EV charger installation costs, up to $1,000 for residential properties.
Your utility territory dramatically affects whole-home electrification economics. PECO has the clear advantage; Duquesne has the hardest math.
SE PA (Philadelphia)
Best economics: highest rate, best solar production, and EAP stacking. Combined HP rebates can reach $1,950.
Central/NE PA
Strong rates but net metering at risk (hourly LMP proposed July 2026). Lock in 1:1 credits before tariff change.
Pittsburgh
Lower solar production (western PA cloud cover) and lowest HP rebate. Longest payback in PA.
SE/SC PA
Highest HP rebate among FirstEnergy PA utilities. Good solar production in eastern territory.
PPL Net Metering Risk
PPL has proposed shifting from 1:1 retail net metering to hourly LMP-based credits (expected July 2026). This would dramatically reduce the value of net metering for PPL customers. Systems installed before the tariff change may be grandfathered. If you are in PPL territory, installing solar now to lock in current net metering is critical.
The order matters. Two federal deadlines and a potential PPL tariff change dictate the optimal sequence.
Lock in Section 30C ($1,000) before it expires. PECO customers also get $300 utility rebate. This is the simplest and fastest install (1-2 days).
Deadline: June 30, 2026
Size for current electric use PLUS expected heat pump demand (add 4-5 kW for Zone 5A). Lock in 1:1 net metering before potential PPL tariff shift to hourly LMP (July 2026). If using PPA/lease, construction must begin before July 4, 2026 for Section 48E.
Urgency: PPL tariff change possible July 2026
Once solar is online and generating net metering credits, the heat pump electricity cost is effectively covered. This makes the gas-to-HP switch much more attractive because the $860/year HP operating cost is offset by solar. Act 129 Phase V (June 2026) may offer higher HP rebates.
Flexible timeline — no hard deadline
A typical PA whole-home electrification bundle costs $33,200-$42,800 before incentives: solar panels ($22,000-$26,000 for 12 kW), heat pump ($10,000-$15,000 ducted central), and EV charger ($1,200-$1,800 Level 2). After Act 129 rebates, EAP bonus (PECO), and Section 30C EV credit, net cost is approximately $31,000-$40,000. Add 6% PA sales tax on solar equipment (~$1,400). There is no federal residential solar or heat pump tax credit in 2026.
No. Section 25D (residential solar ITC) and Section 25C (heat pump energy efficiency credit) both expired December 31, 2025. PA homeowners purchasing solar or heat pumps with cash or a loan receive $0 in federal tax credits. The only federal benefit available is Section 30C for EV chargers ($1,000, expires June 30, 2026) and Section 48E for solar leases/PPAs (30% ITC claimed by the third-party system owner, not the homeowner).
PA SRECs (Solar Renewable Energy Credits) are worth $22-$35 per MWh. A 12 kW solar system generates approximately 13-14 SRECs per year. At current prices, that earns $286-$490 annually, or $4,290-$7,350 over 15 years. If the PRESS Act passes (raising the solar carve-out from 0.5% to 5.5%), SREC prices could increase substantially. You must own the solar system to keep SREC income — PPA/lease providers retain SRECs.
The savings from switching gas to a heat pump in PA are narrow. Gas heating costs approximately $1,300/year ($1.60/therm), while a heat pump costs approximately $860/year at PA electric rates ($0.20/kWh, COP 2.8). That is only $440/year in fuel savings. However, when combined with solar panels that offset the heat pump electricity cost, the combined ROI improves significantly. If you are replacing oil ($2,300/yr) or propane ($2,100/yr), the fuel switching savings are much larger ($1,440/yr or $1,240/yr respectively).
PECO territory (southeastern PA / Philadelphia) has the best economics due to: highest electric rate ($0.21/kWh = more net metering value), best solar production (1,250 kWh/kW/yr), and the unique ability to stack PECO Act 129 rebates ($300) with EAP bonuses ($500-$1,650). Combined, PECO customers can receive up to $1,950 in heat pump rebates. PPL territory is second-best for rates but faces net metering risk. Duquesne Light (Pittsburgh) has the weakest economics due to lower solar production and the lowest HP rebate ($200).
Section 30C expires June 30, 2026. The credit covers 30% of EV charger installation costs, up to $1,000 for residential. The charger must be installed AND placed in service before June 30, 2026. After that date, there is no federal EV charger incentive. If you are bundling solar + heat pump + EV charger, install the charger first to lock in the 30C credit.
Yes. While homeowners cannot claim the 25D residential ITC (expired), third-party financing companies can claim the Section 48E commercial ITC (30%) on solar systems they own and lease to you. This benefit is passed through as a lower monthly PPA or lease rate. You pay $0 down, but you do not own the system, you do not keep SREC income, and you cannot sell the system with your home. The third-party system owner must begin construction before July 4, 2026.
No. Pennsylvania does NOT have a statewide solar property tax exemption. Solar panels add to your assessed property value, which increases your property tax bill. This is a significant negative compared to neighboring states (NJ, MD, CT, MA) that all exempt solar from property taxes. The increased property tax ($200-$400/year on a typical system) should be factored into your payback calculation.
Payback depends on your utility territory and current heating fuel. In PECO territory switching from gas: approximately 11-13 years. In PPL territory: 12-14 years. In Duquesne territory: 13-16 years. If replacing oil or propane (rather than gas), subtract 2-3 years. These estimates include net metering savings, SREC income, fuel switching savings, and Act 129 rebates, but no federal tax credits for solar or heat pump (expired 2025).
For most of PA (IECC Zone 5A), a hybrid or dual-fuel system is strongly recommended. It pairs a heat pump with your existing gas furnace as backup for the coldest days (below 15-25 degrees F). The heat pump handles 80-90% of heating hours efficiently, and the gas backup kicks in during extreme cold. In PECO territory, the $250 EAP dual fuel adder is an additional incentive. In Zone 4A (southeastern PA), a standalone heat pump can handle most winters without gas backup.
The optimal sequence is: (1) EV charger first — lock in Section 30C credit before June 30, 2026. (2) Solar panels second — lock in 1:1 net metering before potential PPL tariff changes (July 2026). Size the system for your current use PLUS expected heat pump load. (3) Heat pump last — it adds the most value after solar is producing because net metering covers the increased electricity demand. If financing is tight, start with solar + EV charger and add the heat pump in year 2-3.
A heat pump adds approximately 4,000-6,000 kWh/year to your electricity consumption in PA (varies by climate zone). In Zone 4A (Philadelphia), add 3-4 kW. In Zone 5A (most of PA), add 4-5 kW. In Zone 6A (extreme north), add 5-7 kW. For example, if your home needs 8 kW for existing electric use, a Zone 5A home with a heat pump should install 12-13 kW total.
