Section 25D expired December 31, 2025. All prices shown are what you actually pay. No 30% credit to subtract. PA solar still works financially through net metering + SREC income, but transparency about real costs matters more than ever.
We offer three panel tiers at transparent per-watt pricing. The right tier depends on your roof size, budget, and financing preference.

PA solar is cheaper than most neighboring states, but has fewer incentives. Here is the trade-off.
| State | $/W Range | Federal ITC | State Rebate | SREC Value | Net Metering |
|---|---|---|---|---|---|
| Pennsylvania | $2.70-$3.17 | $0 | None | $22-$35 | 1:1 |
| New Jersey | $2.80-$3.30 | $0 | None | $85-$95 | 1:1 |
| Massachusetts | $3.20-$3.50 | $0 | SMART | SMART $0.03/kWh | 1:1 |
| New York | $3.00-$3.40 | $0 | NY-Sun | N/A | VDER |
| Maryland | $2.80-$3.20 | $0 | None | $50-$70 | 1:1 |
PA has the lowest installation cost but also the weakest SREC market ($22-$35 vs NJ's $85-$95). PA's advantage is competitive installer pricing and a simple incentive structure.

Estimates based on average 2026 PA solar pricing at $3.00/W, SREC spot ~$28/SREC, 1:1 retail net metering, 6% PA sales tax (applies to solar), NO PA state rebate, NO property tax exemption. Section 25D residential ITC expired Dec 31, 2025 -- $0 federal tax credit for cash/loan purchases.
Section 25D is dead. Any installer showing $0.30 ITC in their quote is misleading you. Cash/loan purchases get $0 federal credit.
PA solar should cost $2.70-$3.17/W. Anything above $3.50/W without battery storage is overpriced for the PA market.
Refuse any quote that shows only a total price without itemizing panels, inverter, labor, permits, and margin. You should know where every dollar goes.
PA SRECs are market-traded at $22-$35/SREC. No one can guarantee future SREC prices. Be wary of projections using $50+ SREC values unless PRESS legislation passes.
PA solar costs $2.70-$3.17 per watt depending on panel tier. A typical 12 kW system runs $32,400-$38,040. PA exempts solar equipment from the 6% sales tax, saving approximately $2,000. There is no federal residential tax credit (25D expired December 31, 2025). Payback varies by utility territory from approximately 11.5 years (PECO) to 13.7 years (FirstEnergy).
The per-watt price includes panels, inverter(s), racking, electrical balance of system, installation labor, permits, interconnection, design/engineering, and installer overhead. It does NOT include battery storage (add $10K-$15K), roof repairs, or main panel upgrades. NuWatt pricing is fully transparent with itemized quotes.
PA solar ($2.70-$3.17/W) costs less than MA ($3.20-$3.50/W), CT ($3.10-$3.40/W), and RI ($3.00-$3.30/W) due to lower labor costs, less regulatory complexity, and a competitive installer market. However, PA also has fewer incentives (no state rebate, lower SREC values) which partially offsets the cost advantage.
Without the 25D ITC, PA solar payback ranges from approximately 11.5 years in PECO territory (highest rate, best irradiance) to 13.7 years in FirstEnergy territory (lower rate, lower irradiance). Payback is driven by net metering savings and SREC income only. Adding the Act 129 utility rebate shortens payback by 3-6 months.
With no residential ITC, cash purchase payback is approximately 8-10 years in PA. A PPA/lease requires $0 upfront and offers immediate bill savings (20-40% below retail) because the financing company claims the 30% Section 48 ITC. For homeowners who cannot afford $32K-$38K upfront, PPA/lease is increasingly attractive in the post-ITC landscape.
Installation costs are similar ($2.78-$2.98/W standard tier). The difference is in economics: PECO territory (Philadelphia) has better irradiance (4.5-4.9 PSH vs 4.0-4.5 for PPL) and higher Act 129 rebates ($1,950 max vs $850). PPL territory also faces net metering tariff change risk around July 2026, making PECO territory a more stable solar investment.
The cheapest cash purchase uses Hyundai HiE-S440VG entry-tier panels at $2.70-$2.90/W. A 10 kW system costs approximately $27,000-$29,000. The cheapest way to solar with no money down is a PPA at $0 upfront with rates 20-40% below your current utility bill. Both options include SREC income and net metering.
