Going Solar in Pennsylvania — Key Insights
1. Pennsylvania Solar Market Overview
Pennsylvania has a meaningful SREC market — each MWh produced generates an SREC worth $20–$60 depending on market conditions, providing ongoing revenue beyond net metering savings. Net metering is required by PA law. Philadelphia area has higher electricity rates ($0.18–$0.22/kWh) than western PA, improving ROI in the southeast. PA also has significant cloud cover that reduces output vs southern states.
2. Top Tip for Pennsylvania Solar Buyers
Register for Pennsylvania's SREC program immediately after installation — it provides income beyond net metering. Track SREC prices on SRECTrade or SP AMS and sell when favorable. Philadelphia's higher electricity rates improve solar payback vs western PA. Get 3+ installer quotes — PA has a competitive market.
3. System Size Guide for Pennsylvania
Average Pennsylvania home uses ~1,000–1,200 kWh/month (higher in hot climates with AC). A 6–8 kW system typically covers most usage. Always get a system sized to 90–110% of your actual annual consumption — oversizing costs more without proportional benefit under most net metering policies.
FAQs — Solar Panels in Pennsylvania
Solar panels in Pennsylvania cost $23,760 on average for a 7 kW system before the 30% ITC. After the credit, net cost is ~$16,632. Pennsylvania's SREC market adds $20–$60 per MWh in ongoing revenue — improving total returns. Payback: 9–13 years, shorter in Philadelphia's high-rate territory.
Solar is financially positive for most Pennsylvania homeowners, though the calculus changed in 2026 after the federal residential ITC expired on December 31, 2025. Pennsylvania's incentives: Federal 30% ITC + PA SREC market (Solar Renewable Energy Credits) + Net Metering (required by law for all utilities). Estimated payback without federal ITC: 9–13 years. With a 25-year panel lifespan and rising electricity rates, solar still provides positive lifetime returns in most states.
Most Pennsylvania homes need a 5–10 kW system. A 7 kW system produces approximately 10,731 kWh/year in Pennsylvania. Divide your annual kWh usage by that figure to estimate the right size. Your installer will perform a site assessment to optimize for your specific roof and usage patterns.
Solar financing options in Pennsylvania in 2026: (1) Cash purchase — best long-term ROI; no federal ITC (expired 12/31/2025) but state incentives apply; typically $100–$250/month in energy savings. (2) Solar loan — own the system; pay from energy savings; rates 5–10% APR via GreenSky, Mosaic, or your installer. (3) Solar lease/PPA — $0 down; the solar company may still qualify for a commercial tax credit through 2027 and passes savings to you via rates below your utility bill — more competitive now that the homeowner cash ITC is gone. (4) HELOC — often lowest interest rate (6–8% APR). Avoid loans with "dealer fees" above 2% — these inflate the effective loan amount.
The ITC expiry changed the comparison. Previously, buying solar gave you a $7,128 federal credit (30% of cost) that leasing didn't — making buying clearly superior. In 2026, that credit is gone for new purchases, but solar companies (lease/PPA providers) can still claim a commercial credit through 2027 and may pass savings to you via lower lease rates. If your state has strong incentives (Pennsylvania's state credit further benefits purchase), buying/financing still typically produces better 25-year returns. Leasing makes sense for zero upfront cost with still-lower-than-utility rates.
