PA's $0.18/kWh average rate is lower than New England — so TPO savings are smaller. But SRECs ($25–40 each), a 6% sales tax exemption, and the 30% Section 48/48E ITC still make leases and PPAs a viable $0-down path to solar. Here's the honest math.

The honest assessment for Pennsylvania homeowners
The honest truth: Pennsylvania's lower electricity rates ($0.18/kWh average) mean TPO savings are smaller than in New England states where rates exceed $0.25/kWh. Net metering at avoided cost (not full retail) further reduces the value of exported solar. These are real limitations you should understand.
But TPO still works in PA because: The Section 25D residential tax credit is dead — cash and loan buyers get $0 from the IRS. Through a lease or PPA, the financing company captures the 30% ITC under Section 48/48E, lowering your payments. PA's SREC market ($25–40 per SREC) adds production income that the system owner factors into lower rates. And the 6% sales tax exemption reduces install costs.

The federal residential solar tax credit (Section 25D) expired December 31, 2025. If you buy solar with cash or a loan in 2026, you get $0 from the IRS. But Section 48/48E — the commercial investment tax credit — is still available for companies that own solar systems. Here is how it works in Pennsylvania:
A financing company (the "third-party owner") purchases and installs solar panels on your roof. You don't buy the system — you agree to either lease it (fixed monthly payment) or buy the power it produces (PPA, per-kWh rate).
Because the financing company legally owns the system, it files IRS Form 3468 and claims the 30% Investment Tax Credit under Section 48/48E. On a $30,000 system, that's $9,000 back from the IRS. The company also claims MACRS depreciation (5-year accelerated schedule + 20% bonus in 2026).
The financing company doesn't pocket the ITC — it uses the $9,000+ in tax benefits to reduce your monthly payment. This is why lease/PPA payments are typically 20–40% lower than what you'd pay on a standard solar loan without the ITC.
Your lease/PPA payment is locked in below your current electric bill rate. You save money starting month one. The system owner handles all maintenance, monitoring, and warranty claims.
With NuWatt's Propel program, the third-party owner transfers full ownership to you at year 5 — after the ITC recapture period expires. You get the best of both worlds: ITC savings upfront, full ownership long-term.
PA-specific note: Propel (NuWatt's ownership-transfer program) is not available in Pennsylvania. PA's lower rates and avoided-cost net metering make the Propel financial model less favorable here compared to high-rate states. Standard leases and PPAs are available statewide.
The Investment Tax Credit powering third-party solar in Pennsylvania. The system owner (financing company) claims this credit — not you, and not the installer.
| Credit Rate | 30% | With prevailing wage + apprenticeship compliance (6% without) |
| Who Claims It | The system owner (financing company) | NOT the homeowner, NOT the installer |
| Residential Eligibility | Yes — via third-party ownership | TPO company owns the system, leases/PPAs it to you |
| Construction Deadline | Begin construction before July 4, 2026 | OBBBA sunset — projects must start before this date |
| Minimum Hold Period | 5 years | System owner must hold for 5 years or face ITC recapture |
| Stackable Bonuses | Domestic content (+10%), Energy community (+10%) | Can reach 50%+ total credit on qualifying projects |
| MACRS Depreciation | 5-year schedule + 20% bonus (2026) | Additional tax benefit for the system owner |
PA's coal heritage means many communities qualify for the energy community adder, potentially pushing the ITC to 40% or higher.
Based on PA average: 9 kW system, $2.85/W = $25,650 total cost, $0.18/kWh utility rate. No Propel column — the program is not available in Pennsylvania.
Note: PA's lower rates mean all savings figures are smaller than NE states. This is honest math, not inflated marketing.
| Cash | Loan (6-8%) | Lease | PPA | |
|---|---|---|---|---|
| Upfront Cost | $25,650 | $0 | $0 | $0 |
| Federal ITC | $0 | $0 | $7,695 (owner) | $7,695 (owner) |
| Monthly Payment | $0 | $180–250/mo | $70–120/mo | Varies |
| Year 1 Savings | $1,944 | $0–500 | $300–600 | $400–800 |
| Ownership | Immediate | Immediate | Never (unless buyout) | Never (unless buyout) |
| Year 25 Savings | $48,600 | $28,000–36,000 | $12,500–20,000 | $14,000–22,000 |
| Maintenance | You | You | Included | Included |
Honest note: Cash purchase has the highest 25-year savings even without the ITC — because there's no interest, no escalator, and no payments to a third party. But it requires $25,650 upfront and you absorb all maintenance costs. TPO wins on accessibility ($0 down) and risk transfer (maintenance included), not necessarily on total ROI.
Pennsylvania's Alternative Energy Portfolio Standards (AEPS) require utilities to purchase Solar Renewable Energy Credits. One SREC equals one megawatt-hour (1,000 kWh) of solar production. PA SRECs currently trade at $25–40 each — lower than New Jersey's ADI but still meaningful production income.
Your solar system generates electricity and earns SRECs (1 SREC per 1 MWh produced)
In most TPO contracts, the system owner retains the SRECs
The owner sells SRECs on the PJM-GATS market ($25–40 each)
That revenue is factored into your lower lease/PPA payment
Always read your contract to understand SREC ownership. Some providers negotiate partial SREC sharing — ask before signing.
| System | MWh/yr | @$25 | @$32.50 | @$40 |
|---|---|---|---|---|
| 6 kW | 7.2 | $180 | $234 | $288 |
| 9 kW (avg) | 10.8 | $270 | $351 | $432 |
| 12 kW | 14.4 | $360 | $468 | $576 |
Based on 1,200 kWh/kW annual production (Eastern PA). Western PA may produce ~1,100 kWh/kW. SREC prices are market-driven and fluctuate.
This is one of the most important differences between Pennsylvania and states like Massachusetts, New Jersey, or Maine. Understanding it is critical to evaluating whether a solar lease makes sense for your home.
Pennsylvania is a deregulated electricity market. Rates vary by utility territory, and your utility determines how much a solar lease or PPA can actually save you. Act 129 requires utilities to offer energy efficiency programs that may include small solar incentives.

Pennsylvania's Act 129 requires electric distribution companies to implement energy efficiency and conservation programs. PECO, PPL, and Duquesne Light each have Act 129 programs that may include modest incentives for solar or energy efficiency upgrades. Check with your utility for current offerings — these change annually and can stack with TPO savings.
Solar leases and PPAs are not the right fit for every PA homeowner. Here is an honest breakdown of when TPO works well and when it does not.
A complete view of what Pennsylvania offers (and does not offer) for solar in 2026.
Expired Dec 31, 2025. Cash/loan buyers get nothing.
Financing company claims credit. Deadline: July 4, 2026.
One SREC per MWh. System owner retains in most TPO contracts.
Solar equipment exempt from PA 6% sales tax.
Varies by municipality. Check with your county assessor.
Act 213. Exported solar earns wholesale + adder, not retail rate.
The clock is ticking. Here are the dates that matter for PA solar financing.
The One Big Beautiful Bill Act (OBBBA) requires projects to begin construction before July 4, 2026 to qualify for Section 48/48E. After this date, the 30% ITC for third-party solar owners may be eliminated or significantly reduced.
If bundling solar + EV charger, the $1,000 EV charger credit (Section 30C) expires June 30, 2026.
The 20% bonus depreciation available in 2026 drops to 0% in 2027, reducing the TPO company's tax benefit and potentially increasing your lease/PPA payments.
For PA homeowners: PA's permitting process is generally faster than New England (2–4 weeks), but utility interconnection can take 4–8 weeks depending on your utility. Starting the process by spring 2026 ensures your project meets the July 4 construction-start requirement.
Not as a homeowner. The federal residential solar tax credit (Section 25D) expired December 31, 2025. Homeowners who buy with cash or a loan receive $0. Through a solar lease or PPA, the third-party system owner claims the 30% ITC under Section 48/48E and passes the savings to you through lower payments.
It depends on your rate. At PA's average of $0.18/kWh, the savings margin is narrower than in high-rate states. A PPA at $0.09–0.14/kWh saves $0.04–0.09 per kWh — meaningful over 25 years ($12,500–$20,000) but less dramatic than in Massachusetts or Connecticut. If your utility charges over $0.20/kWh, TPO becomes more compelling. If you pay under $0.15/kWh, carefully evaluate whether the savings justify the 25-year commitment.
Pennsylvania's Act 213 provides net metering at avoided cost — the wholesale rate plus a small adder. This is NOT full retail credit. Exported solar is worth less per kWh than what you pay for imported power. This means solar is most valuable when you consume the power directly (self-consumption) rather than exporting it. Larger systems that over-produce may see diminished returns.
SRECs (Solar Renewable Energy Credits) are tradable certificates worth $25–40 each. One SREC is generated per 1 MWh (1,000 kWh) of solar production. In most TPO contracts, the system owner retains the SRECs and factors their value into your lower lease/PPA payment. Always read your contract to understand who owns the SRECs — if you want them, negotiate before signing.
Pennsylvania does not have a statewide solar property tax exemption. This means solar may increase your property tax assessment in some municipalities. Check with your county assessor before installing. Some municipalities offer local exemptions, but this varies widely across the state.
Not currently. NuWatt's Propel program is available in Maine and Texas. Standard solar leases and PPAs are available in Pennsylvania. PA's lower electric rates and avoided-cost net metering make the Propel financial model less favorable here compared to high-rate states.
Savings vary by utility. PECO (Philadelphia area) and PPL (Lehigh Valley, central PA) customers typically pay higher rates and see better solar savings. Duquesne Light (Pittsburgh) rates are moderate. Compare your actual rate to the proposed PPA rate — a PPA only makes financial sense if the per-kWh rate is meaningfully below your utility rate after accounting for net metering limitations.
The critical deadline is July 4, 2026. The third-party system owner must begin construction before this date to claim the Section 48/48E 30% ITC. PA's permitting process is generally faster than New England states (2–4 weeks), but starting by spring 2026 is still recommended.
