Solar Panels in Pennsylvania: 2026 Cost Guide, Incentives & Savings

Pennsylvania Solar Costs at a Glance

Installed solar in Pennsylvania costs $2.70–$3.60 per watt in 2026, putting a typical 8kW system at $21,600–$28,800. PA runs about 5–10% above the national average — partly due to higher union labor rates in Philadelphia and Pittsburgh, and partly because older PA housing stock sometimes requires roof prep work before installation.

The good news: Pennsylvania’s incentive stack is genuinely strong even without the federal ITC (which expired December 31, 2025). SREC income, full retail net metering, and a complete sales tax exemption on solar equipment make PA one of the better state markets in the Mid-Atlantic.

Pennsylvania Solar Cost by System Size (2026)

Here’s the full cost breakdown for the most common residential system sizes in PA, including estimated SREC income and payback:

System Size	Installed Cost (PA)	Annual SREC Income	Monthly Bill Savings*	Payback Period
6 kW	$16,200 – $21,600	$250 – $440/yr	$90 – $130/mo	9–12 years
8 kW	$21,600 – $28,800	$300 – $585/yr	$120 – $170/mo	8–11 years
10 kW	$27,000 – $36,000	$380 – $730/yr	$150 – $210/mo	8–11 years
12 kW	$32,400 – $43,200	$450 – $875/yr	$180 – $250/mo	9–12 years

* Monthly savings at $0.14–$0.22/kWh with net metering. PECO customers (Philadelphia area) see higher savings due to higher rates. Payback includes SREC income but excludes federal ITC (expired Dec 31, 2025).

Pennsylvania Solar Incentives in 2026

PA has no state income tax credit for solar — but the combination of SREC income, net metering, and tax exemptions adds up to a meaningful incentive stack. Here’s what’s available:

1. SREC Income: Pennsylvania’s Hidden Bonus

Pennsylvania’s Solar Renewable Energy Credit (SREC) program is one of the most underappreciated solar incentives in the Mid-Atlantic. For every 1,000 kWh (1 MWh) your system generates, you earn one SREC — which you can sell on the open market to utilities that need them to meet their renewable portfolio standards.

In 2026, PA SRECs trade at approximately $50–$97 per credit. A typical 8kW system in Pennsylvania generates roughly 9,000–10,000 kWh per year — meaning 9–10 SRECs annually. At current prices, that’s $450–$970 per year in additional income on top of your electric bill savings.

System Size	Annual Generation (PA avg)	SRECs Earned/Year	Annual SREC Income
6 kW	7,200–7,800 kWh	7–8	$350–$776
8 kW	9,000–10,000 kWh	9–10	$450–$970
10 kW	11,000–12,500 kWh	11–13	$550–$1,261

SREC prices fluctuate with market conditions. Check SRECtrade.com or SolSystems for current PA SREC spot pricing.

2. Net Metering: Full Retail Credit

Pennsylvania law requires all investor-owned utilities to offer net metering at the full retail electricity rate. When your panels produce more than you use, the excess spins your meter backward — earning a credit at the same rate you’d pay to buy that electricity.

Unused credits roll forward month-to-month. At the end of each year, utilities pay out any remaining excess generation credit at the wholesale rate (lower than retail). The practical implication: size your system to cover your annual usage, not your peak summer month, to maximize net metering value.

3. Pennsylvania Sales Tax Exemption

Solar energy equipment is 100% exempt from Pennsylvania’s 6% sales tax. On a $25,000 system, that’s $1,500 saved at purchase — no paperwork, no application, just a lower invoice. Your installer should automatically apply this exemption. If they don’t, ask.

4. Property Tax Exemption (Act 129)

Under Pennsylvania law, the value that solar adds to your home is exempt from property tax assessment. A solar installation typically adds $15,000–$25,000 to home value. Without the exemption, that would mean an extra $150–$300/year in property taxes (depending on your county rate). The exemption makes that a non-issue.

5. Federal ITC: What Changed in 2026

The federal Investment Tax Credit (ITC) — which had been 30% of system cost — expired December 31, 2025 for residential installations. If you installed before that date, you could claim 30% back on your federal taxes. In 2026, that credit is no longer available to new residential buyers.

This is significant: it adds roughly $6,000–$9,000 to the effective cost of a typical PA system versus what buyers paid in 2024–2025. PA’s state-level incentives (SREC income, net metering, tax exemptions) partially offset this, but the math is less favorable than it was 12 months ago. Payback periods are longer than the 6–8 year window buyers saw during the ITC era.

The honest take: solar still pencils out for most PA homeowners with bills above $130/month and a 10+ year time horizon. But the numbers require more scrutiny in 2026 than they did when the ITC was active. Use our PA solar assessment tool to get your specific break-even point.

Pennsylvania Utility Rates: PECO, PPL & Duquesne Light

Your utility company and their rates are the single biggest variable in your solar ROI. Higher rates mean more savings per kWh your panels produce. Here’s where PA’s three major utilities stand in 2026:

PECO (Philadelphia & Southeastern PA)

PECO charges residential customers approximately 18–22 cents/kWh in 2026 — among the highest rates in the state. The combination of high rates and full retail net metering makes PECO territory the strongest solar market in Pennsylvania. A Philadelphia-area homeowner with a $150/month bill and an 8kW system can expect:

• $1,560–$1,800/year in direct bill savings
• $450–$970/year in SREC income
• Effective payback: 8–10 years (no ITC)

PPL Electric (Central & Eastern PA — Allentown, Reading, Harrisburg)

PPL rates run 15–19 cents/kWh in 2026. Mid-range for PA — solar works well here, particularly in the Lehigh Valley (Allentown, Bethlehem) where sun hours are solid and roof stock is good. PPL’s net metering is straightforward: credits carry forward at retail and settle annually. An 8kW system in the Allentown area typically pays back in 9–11 years.

Duquesne Light (Pittsburgh & Allegheny County)

Duquesne Light serves Pittsburgh and surrounding Allegheny County at approximately 14–17 cents/kWh. Pittsburgh gets about 4.2 peak sun hours per day on average — less than Philadelphia but enough for solar to work. The lower rates and slightly fewer sun hours mean payback in Pittsburgh runs 1–2 years longer than in Philadelphia. An 8kW Pittsburgh system typically pays back in 10–12 years.

Utility	Service Area	Rate (2026)	Peak Sun Hours	8kW Payback (est.)
PECO	Philadelphia, SE PA	18–22¢/kWh	4.5–4.8	8–10 years
PPL Electric	Allentown, Reading, Harrisburg	15–19¢/kWh	4.3–4.7	9–11 years
Duquesne Light	Pittsburgh, Allegheny County	14–17¢/kWh	4.0–4.3	10–12 years

PA Solar ROI: The 25-Year Math

Let’s run the numbers for a typical PA homeowner: $130/month electric bill, 8kW system, PECO territory (Philadelphia area, ~$0.20/kWh average rate).

• System cost: $25,200 (8kW at $3.15/watt, PA average)
• Sales tax savings: −$1,512 (6% exemption applied at purchase)
• Effective upfront cost: $23,688
• Year 1 electric bill savings: ~$1,560/year (offset 100% of $130/mo bill)
• Year 1 SREC income: ~$720/year (9 SRECs × $80 avg price)
• Total Year 1 benefit: $2,280
• Payback period: ~10.4 years (accounting for 3%/year rate escalation)
• Year 25 cumulative savings: ~$74,000 (after paying off system)

After the ~10-year payback, you have 15+ years of essentially free electricity — plus SREC income for the years the PA SREC market remains active. Even in Pittsburgh (Duquesne Light territory with lower rates), a similar system reaches payback in 11–12 years and generates $55,000–$65,000 in 25-year savings.

Best Cities for Solar in Pennsylvania

Not all PA cities are equal for solar. Here’s how the four major metros compare:

Philadelphia: Strongest ROI in PA

Philadelphia runs on PECO — the highest rates in the state — and gets 4.5–4.8 peak sun hours per day. That combination produces the best solar economics in Pennsylvania. The city also has a well-developed installer market, which keeps costs competitive. Best-case payback: 8 years for a well-sited system.

Pittsburgh: Longer Payback, Still Works

Pittsburgh is cloudier than Philadelphia — roughly 300 cloudy days per year — and Duquesne Light rates are lower. Solar still makes sense for homeowners with high bills, but the math requires a longer time horizon. The city has a growing installer base, which is pushing prices down. Typical payback: 10–12 years.

Allentown: Lehigh Valley Sweet Spot

Allentown and the broader Lehigh Valley fall under PPL Electric at 15–19 cents/kWh. The area gets solid sun and has a competitive installer market thanks to proximity to Philadelphia. SREC income tends to be strong here. Typical payback: 9–11 years.

Reading: PPL Territory, Strong Value

Reading homeowners are also on PPL and see similar economics to Allentown. The lower cost of living in Reading means installer competition can be strong — shoppers who get 3+ quotes often land at the low end of the installed cost range. Typical payback: 9–11 years.

When Solar Doesn’t Work in Pennsylvania

Solar is a good fit for most PA homeowners — but not all. Here’s when the numbers don’t work:

• Electric bill under $100/month. Low usage means limited savings. Payback stretches to 15+ years and the system may never deliver strong ROI.
• North-facing or heavily shaded roof. Heavy tree cover (common in rural PA) or north-facing orientation can cut production 30–50%. Run the numbers carefully before installing.
• Roof needs replacement within 10 years. Removing and reinstalling panels for a roof job costs $2,000–$5,000. Do the roof first if it’s in poor shape.
• Planning to sell within 5 years. You’ll likely recoup solar’s value at resale, but in a slow market you may not recover the full investment.
• Duquesne Light customer with low bill. Pittsburgh’s combination of lower rates, fewer sun hours, and higher installed costs means the math is tight below $110/month in electricity spend.

FAQ: Solar Panels in Pennsylvania

How much do solar panels cost in Pennsylvania in 2026?

$2.70–$3.60 per watt fully installed, averaging around $3.10/watt. A typical 8kW system runs $21,600–$28,800. PA costs run 5–10% above the national average due to labor costs and housing stock. The federal ITC expired December 31, 2025, so incentives now consist of SREC income, net metering at retail rates, and the 6% sales tax exemption. Use our sizing calculator to estimate your system cost.

What are the best solar incentives in Pennsylvania in 2026?

PA’s strongest incentives: (1) SREC income — $450–$970/year for a typical 8kW system; (2) net metering at full retail rates through PECO, PPL, and Duquesne Light; (3) 6% sales tax exemption on all solar equipment; (4) property tax exemption on the home value solar adds. The federal ITC (30%) expired at the end of 2025.

Is solar worth it in Pennsylvania in 2026?

Yes, for most homeowners paying $130+/month for electricity with a 10+ year time horizon. Without the federal ITC, payback periods are longer than in recent years — typically 8–11 years depending on utility and city. But after payback, panels generate free electricity for 15+ more years plus ongoing SREC income. Get your specific estimate here.

Does Pennsylvania have net metering for solar in 2026?

Yes. PECO, PPL, and Duquesne Light all offer full retail-rate net metering under PA PUC rules. Excess generation credits your bill at the same rate you pay, roll forward monthly, and settle annually at wholesale. PA net metering is strong compared to other Mid-Atlantic states — no recent adverse rulings or export rate reductions.

How much does solar save on electric bills in Pennsylvania?

A properly sized 8–10kW system in PA offsets 80–100% of a typical household’s electricity use. At $130/month, that’s $1,560/year in bill savings plus $450–$970/year in SREC income — roughly $2,000–$2,500 total annual benefit. Over 25 years with 3% annual rate increases, that compounds to $60,000–$80,000 in total savings after system payoff. Run your exact numbers here.
