With moderate electric rates and no federal residential ITC, the tariff math is tighter here than in New England — making panel selection, SREC income, and financing choice critical for protecting your investment.
The US solar industry faces the most complex tariff environment in its history. Four separate trade actions — each with its own legal basis, rate structure, and exemption rules — are stacking on top of each other. The combined effective tariff rate on imported solar modules from Southeast Asia, which supplies most of the US residential market, now ranges from 35% to 55%.
For Pennsylvania homeowners, these tariffs compound an already challenging market. PA electric rates are moderate — averaging $0.17-0.19/kWh compared to $0.28-0.32/kWh in Massachusetts — which means each kilowatt-hour of solar production offsets less expensive electricity. The tariff increase of $0.10-0.25/W adds roughly 6-13 months to an already longer payback period. This makes choosing the right panel tier and leveraging SRECs even more important for PA buyers.
Imposed in 2018 on imported crystalline silicon PV cells and modules. Extended through February 2026 with escalating rates. Applies to virtually all imported modules regardless of country of origin, with the first 5 GW of cells annually exempt.
Anti-dumping and countervailing duties target Chinese-manufactured cells, including those routed through Southeast Asian countries (Cambodia, Malaysia, Thailand, Vietnam). The Commerce Department confirmed circumvention findings in 2024. The two-year moratorium expired June 2024 and these duties now fully apply.
Broad tariffs on Chinese goods including solar panels, inverters, racking, and balance-of-system equipment. Combined with AD/CVD, Chinese module imports face 50%+ effective rates, making them uneconomical for the US market.
Additional tariffs targeting solar imports from Cambodia, Vietnam, Malaysia, and Thailand — countries that supply the majority of US residential panels. These are layered on top of existing Section 201 and AD/CVD duties, phasing in through mid-2026.
Chinese-manufactured panels face 50%+ effective rates, making direct import uneconomical. Panels from Cambodia, Vietnam, Malaysia, and Thailand — which historically supplied 80%+ of the US residential market — now carry 35-50% combined tariffs. Only panels manufactured in non-tariff-affected countries (South Korea, North America, Singapore) avoid most of these layers.
Pennsylvania solar costs currently range from $2.70 to $3.10 per watt, depending on utility territory, system size, and panel tier. Tariffs have added $0.10-0.25/W to these prices compared to 2024 levels. For a typical 11 kW system, that is $1,100 to $2,750 more than you would have paid 18 months ago from tariff escalation alone.
The tariff increase compounds a bigger loss: the federal residential tax credit (Section 25D) expired December 31, 2025. In 2024, a homeowner offset 30% of system cost with the ITC. Now that benefit is gone. With PA's moderate electric rates ($0.17-0.19/kWh), the payback period is already longer than in high-rate states — and tariffs push it further. This is why SREC income and the right financing strategy are essential for PA solar economics.
| Cost Component | Pre-Tariff (2024) | Current (Q1 2026) | Change |

Beyond the tariffs you see in trade headlines, there is a separate policy that quietly reshapes which solar panels work for which financing paths. FEOC (Foreign Entity of Concern) rules determine whether a third-party system owner — the company behind your lease or PPA — can claim the 30% Section 48E commercial investment tax credit.
If a panel is manufactured by or contains critical components from an entity controlled by China, Russia, Iran, or North Korea, it is FEOC-non-compliant. The financing company cannot claim the 48E ITC on that system. Without the 30% credit, the company must recover their full investment from your monthly payments — meaning significantly higher lease/PPA rates.
For cash and loan buyers, FEOC is not directly relevant. You can choose any panel tier, including the most affordable options from non-FEOC-compliant manufacturers. But for lease or PPA customers, FEOC compliance is a hard requirement. Note that NuWatt Propel is not yet available in Pennsylvania — it is coming soon.
Eligible for Section 48E ITC in lease/PPA deals. Lower tariff exposure.
Fine for cash/loan purchases. Cannot qualify for 48E ITC in lease/PPA.
July 4, 2026 was the Section 48E begin-construction safe-harbor date, not an expiry. Projects that began construction on or before then locked in the longer timing pathway (placed in service through roughly 2030). Third-party system owners (lease/PPA companies) whose projects begin later still qualify for the 30%+ ITC, but generally must place the system in service by December 31, 2027. The tighter post-2027 window plus rising tariffs reward acting sooner.
Not all panels are affected equally by tariffs. Country of origin, manufacturing supply chain, and FEOC compliance all determine your real cost and financing options. Here is how NuWatt's three panel tiers compare.
Cash or loan buyers seeking lowest upfront cost
Lease/PPA or anyone wanting FEOC assurance and tariff protection
Premium installations, max efficiency, roof-space constrained
For cash/loan buyers, Hyundai 440W saves ~$770 on an 11 kW system compared to Silfab. With PA's moderate rates, minimizing upfront cost is especially important for payback math. For lease/PPA buyers, Silfab is the most cost-effective FEOC option — the 48E ITC more than offsets the base price difference. REC 460W (+$0.19/W) is worth considering only when roof space is limited and you need maximum watts per square foot.
Tariffs and FEOC rules affect each financing path differently. Your choice of financing determines which panels you can use, how much of the tariff burden you absorb directly, and whether the Section 48E ITC is accessible.
Note: NuWatt Propel financing is not yet available in Pennsylvania. It is currently offered in Maine and Texas, with PA expansion planned. In the meantime, PA homeowners can access Section 48E benefits through standard lease/PPA agreements with FEOC-compliant panels.
You cannot control tariff policy, but you can control your timing, panel selection, and incentive strategy. These five actions reduce the tariff hit on your solar investment.
If you are considering a lease or PPA, July 4, 2026 was the §48E begin-construction safe-harbor date, not an expiry. Projects that began construction on or before then locked in the longer timing pathway; projects that start later still qualify if placed in service by December 31, 2027. The tighter post-2027 window plus rising tariffs reward acting sooner.
Cash and loan buyers can save with Hyundai 440W panels (-$0.07/W). Lease/PPA customers must use FEOC-compliant panels (Silfab or REC) but benefit from the 48E ITC pass-through. Match your panel tier to your financing method.
Pennsylvania SREC-II credits pay $30-45 per megawatt-hour of production. For an 11 kW system producing ~14,300 kWh/year in PA, that is roughly $430-645 per year in SREC income. Combined with 1:1 net metering at $0.17-0.19/kWh, SRECs help recover the tariff increase within 3-5 years.
Pennsylvania exempts solar equipment from the 6% state sales tax. On a $31,350 system, that saves approximately $1,881. This exemption applies regardless of panel tier or financing method and directly offsets a large portion of the tariff increase.
NuWatt pre-purchased Hyundai 440W and Silfab 440W panels before the latest tariff increases. While warehouse stock lasts, your system price reflects pre-tariff module costs. Once depleted, replacements carry the full tariff burden.
Pennsylvania's incentive stack is more modest than New England states, but SRECs, net metering, and tax exemptions still provide meaningful value. Understanding how to maximize each program is critical when tariffs are squeezing margins.
Pennsylvania solar renewable energy credits are earned per megawatt-hour of production. An 11 kW system producing 14.3 MWh/year generates $430-645 annually in SREC income.
Excess solar production is credited at the full retail rate. At PA rates of $0.17-0.19/kWh, each kWh offsets your bill dollar-for-dollar. Available through all four major utilities.
Solar equipment and installation are exempt from PA state sales tax. On a $31,350 system, that saves approximately $1,881 — enough to offset most of the tariff increase on an average system.
Pennsylvania does not have a statewide solar property tax exemption, but many counties and municipalities offer local exemptions or abatements. Check with your county assessor.
The third-party financing company claims the 30% commercial ITC, passing savings through as lower lease/PPA payments. Requires FEOC-compliant panels. July 4, 2026 was the begin-construction safe-harbor date for the longer §48E timing pathway; later starts still qualify if placed in service by December 31, 2027.
Some PA utilities offer additional solar rebates through Act 129 programs. PECO, PPL, Duquesne Light, and Met-Ed have varying incentive structures — check current availability.
The tariff increase of $1,100-2,750 is meaningful but manageable. SRECs alone can recover the full tariff cost within 2-6 years. Over 25 years, an 11 kW system in PA generates $70,000-100,000+ in total value (avoided electricity + SREC income + tax savings), making the tariff impact a small fraction of long-term returns. The key challenge is PA's moderate electric rates, which lengthen payback compared to high-rate states.
Understanding the timeline helps you decide when to act. The window for pre-tariff inventory and the Section 48E deadline are the two most time-sensitive factors for Pennsylvania homeowners.
Two-year pause on Southeast Asian anti-dumping duties ended. Full duties now apply to panels from Cambodia, Vietnam, Malaysia, Thailand.
Federal residential solar tax credit dropped to $0. Pennsylvania homeowners no longer receive any federal tax benefit for cash/loan solar purchases.
Safeguard tariff extended. Additional executive action tariffs on Southeast Asian panels beginning to take effect.
Pre-tariff inventory still available from some installers. SREC market stable. Best window for locking pricing before further tariff escalation.
Projects that began construction on or before this date locked in the longer §48E timing pathway on lease/PPA deals. Projects that begin later still qualify if placed in service by December 31, 2027 — the post-2027 window is just tighter.
New executive action tariffs fully phased in. Pre-tariff inventory expected to be depleted. Projected PA pricing: $3.00-3.30/W.
Pennsylvania has four major electric utilities with rates ranging from $0.16 to $0.19 per kWh — roughly 40-50% lower than Massachusetts or Connecticut. This matters for the tariff discussion because lower rates mean each kWh of solar production saves you less money, extending the time it takes to recover any cost increase.
The practical implication: every dollar of tariff-driven cost increase takes longer to pay back in PA than in a high-rate state. This makes choosing the most cost-effective panel tier critical. Cash buyers should strongly consider the Hyundai 440W at -$0.07/W to minimize upfront cost. Lease/PPA buyers benefit from the 48E ITC pass-through, which partially compensates for the slower payback.
| Utility | Avg Rate ($/kWh) | Annual Savings (11 kW) | Tariff Recovery Time |
|---|---|---|---|
| PECO (Philadelphia) | ~$0.17/kWh | ~$2,431 | 5-14 months |
| PPL (Central/Eastern PA) | ~$0.16/kWh | ~$2,288 | 6-14 months |
| Duquesne Light (Pittsburgh) | ~$0.18/kWh | ~$2,574 | 5-13 months |
| Met-Ed (Northeast PA) | ~$0.19/kWh | ~$2,717 | 5-12 months |
Tariffs are adding approximately $0.10-0.25 per watt to solar panel costs in Pennsylvania. For a typical 11 kW system, that translates to $1,100-2,750 in additional cost. The impact comes from multiple overlapping tariff layers: Section 201 safeguard tariffs (14.75%), AD/CVD anti-dumping duties (15-250% on specific manufacturers), Section 301 China tariffs (25%), and new Southeast Asian duties (14-25%). The total effective rate on imported modules ranges from approximately 35-55% depending on country of origin.
FEOC stands for Foreign Entity of Concern. Under current rules, solar panels manufactured by or containing critical components from entities controlled by China, Russia, Iran, or North Korea are considered FEOC-non-compliant. This matters because third-party system owners (lease/PPA companies) can only claim the 30% Section 48E commercial ITC if the panels are FEOC-compliant. For homeowners choosing a lease or PPA, using FEOC-compliant panels like Silfab (made in North America) or REC means lower monthly payments because the financing company can claim the tax credit. FEOC sourcing thresholds tighten over time (rising from 40% to 50% in 2027), and they apply across both §48E timing pathways — whether construction begins on or before the July 4, 2026 safe-harbor date or later (placed in service by December 31, 2027).
Yes, SRECs are one of the strongest tools PA homeowners have to offset tariff costs. Pennsylvania SREC-II credits currently trade at $30-45 per megawatt-hour. An 11 kW system producing approximately 14,300 kWh per year generates $430-645 in annual SREC income. Over 15 years (the typical SREC market horizon), that is $6,450-9,675 in cumulative SREC revenue. This production-based income is completely unaffected by tariffs because it is tied to energy generation, not equipment cost. SRECs alone can recover the $1,100-2,750 tariff increase within 2-6 years.
The data favors acting sooner. There is no indication tariffs will decrease under the current administration, and multiple tariff layers are still phasing in through mid-2026. Waiting means: (1) higher module prices as pre-tariff inventory depletes, (2) a tighter §48E timing window — the begin-construction safe harbor closed July 4, 2026, so lease/PPA new starts must be placed in service by December 31, 2027, (3) potential SREC market volatility, and (4) continued electricity bills at $0.17-0.19/kWh. The federal residential ITC (Section 25D) expired December 31, 2025 with no scheduled return, so there is no upcoming federal incentive to wait for.
FEOC-compliant panels manufactured in North America, like Silfab panels made in Ontario, Canada and Bellingham, WA, face significantly lower tariff exposure. They are not subject to AD/CVD duties, Section 301 China tariffs, or the new Southeast Asian duties. They may still face some Section 201 tariff on imported cells, but the overall tariff burden is much lower than Southeast Asian alternatives. This is why FEOC-compliant panels, while slightly higher in base price, offer better long-term value and are required for lease/PPA financing that accesses the 48E ITC.
Cash buyers have the most flexibility since FEOC compliance is not required for a direct purchase. The Hyundai 440W is the most affordable option at -$0.07/W below the base price, offering solid performance with a 25-year warranty. For homeowners who want higher efficiency or future-proofing, the Silfab 440W (base price, 30-year warranty, FEOC-compliant) or REC 460W (+$0.19/W, highest efficiency at 22.3%) are worth considering. The Hyundai saves roughly $770 on an 11 kW system compared to Silfab.
Pennsylvania electric rates are moderate compared to New England: PECO averages about $0.17/kWh, PPL around $0.16/kWh, Duquesne Light about $0.18/kWh, and Met-Ed around $0.19/kWh. These lower rates mean each kWh of solar production offsets less expensive electricity, resulting in longer payback periods than states like Massachusetts. An 11 kW system producing 14,300 kWh/year offsets $2,431-2,717 in annual electricity costs at PA rates. The tariff increase of $1,100-2,750 adds roughly 6-13 months to the payback period. SRECs and net metering help close the gap, but PA buyers should factor in that moderate rates make panel quality and pricing even more important.
Yes. With a lease or PPA, the financing company owns the system and absorbs the equipment cost, including tariff impact. Your payment is fixed upfront and does not change based on module pricing. Additionally, the financing company can claim the 30% Section 48E commercial ITC, which lowers the cost they need to recover from your payments. July 4, 2026 was the begin-construction safe-harbor date for the longer §48E timing pathway; projects that start later still qualify if placed in service by December 31, 2027. However, the panels must be FEOC-compliant (Silfab or REC), which are slightly more expensive at the base level. The tighter post-2027 window plus continued tariff and equipment-cost pressure reward locking pricing sooner.
July 4, 2026 was the §48E begin-construction safe-harbor date, not an expiry. Projects that began construction on or before that date locked in the longer timing pathway (placed in service through roughly 2030). Projects that begin construction after July 4, 2026 still qualify for the 30%+ commercial ITC, but generally must be placed in service by December 31, 2027 — a tighter window. This affects lease and PPA timing, since the third-party owner claims the credit. For cash and loan buyers, the date is less relevant since the residential ITC (Section 25D) already expired December 31, 2025. Because tariffs are expected to keep rising, the most defensible reason to act sooner is the tighter post-2027 window plus higher module costs, not any loss of the credit itself.
There is no credible indicator that US solar panel prices will decrease in 2027. Global module prices have dropped significantly (due to Chinese oversupply), but US-specific tariffs prevent those savings from reaching American consumers. Domestic and FEOC-compliant manufacturing capacity is still ramping up and will carry higher production costs than Southeast Asian factories for the foreseeable future. Meanwhile, labor, permitting, and interconnection costs continue their upward trend. The most likely scenario is that 2026 prices represent the floor, with moderate increases through 2027.
