Pennsylvania Solar Guide 2026

Pennsylvania offers solid solar economics with moderate costs, decent net metering, and SREC income. Here's what PA homeowners need to know.

Quick Answer
Pennsylvania offers solid solar economics with below-average costs ($18,900-$21,700 for 7 kW), SREC income ($30-$50 per 1,000 kWh), full retail net metering, and sales tax exemption. Payback runs 8-11 years with 25-year savings of $28,000-$46,000. PECO and PPL customers in eastern PA typically see the best returns.

Pennsylvania Solar Overview

💡
From my experience:

Pennsylvania is what I call a "steady performer" for solar. You will not get the flashy incentives of neighboring New Jersey or Maryland, but the math still works out. The SREC values are modest, but installation costs are below average, which helps. PECO and PPL customers in the eastern part of the state tend to see better economics than western PA.

Pennsylvania sits in the middle tier for solar attractiveness. While incentives aren't as generous as Massachusetts or New Jersey, moderate electricity rates and reasonable installation costs make solar a solid investment for most PA homeowners.

[Editor's Note, Jan 2026]:Pennsylvania SREC prices fluctuate with market conditions. The SREC-II requirements continue through 2030. Check current market rates with your installer or an SREC aggregator for accurate projections.

Pennsylvania SRECs

Pennsylvania has an SREC market, though values are lower than neighboring New Jersey or Maryland.

PA SREC Details

  • Current Value: $30-$50 per SREC
  • One SREC = 1,000 kWh of production
  • 7 kW system ≈ 7-8 SRECs/year = $210-$400 annually
  • SREC-II requirements increasing through 2030

While PA SREC values are modest compared to MA or NJ, they still provide meaningful additional income over your system's life—potentially $5,000-$10,000 over 25 years.

Pennsylvania Incentives

State-Level

  • SRECs: $30-$50/SREC (see above)
  • Sales Tax Exemption: No state sales tax on solar equipment
  • Property Tax Exemption: Some municipalities exempt solar
  • No state tax credit for residential solar

Local Incentives

  • Philadelphia Solar Rebate: Various programs through Philadelphia Energy Authority
  • PECO Territory: Check for utility-specific programs
  • Solarize Campaigns: Group-buy programs in various communities

Federal

  • Cash/Loan: No federal credit (25D expired)
  • PPA/Lease: 30% federal credit (claimed by solar company)

Net Metering Rules

Pennsylvania's net metering rules vary by utility, but generally provide good value:

  • Credit rate: Full retail rate for most utilities
  • System size limit: 50 kW for residential
  • Credit rollover: Monthly rollover, annual true-up
  • Annual true-up: Excess credits paid at avoided cost rate
Net Metering Tip
Size your system to match your annual usage, not exceed it. Excess credits at year-end are paid at a lower "avoided cost" rate, not full retail. Aim for 100% offset, not 150%. (Source: utility tariff filings and DSIRE Database)
