About solar in Pennsylvania

Pennsylvania solar has roughly tripled in five years: 3,198 megawatts installed through early 2026, enough for solar to supply about 2.3% of the Commonwealth's electricity, and Pennsylvania leads the entire 13-state PJM region's interconnection queue — nearly 40 gigawatts of mostly solar and storage projects working toward construction. Growth now reaches well beyond Philadelphia and Pittsburgh, into suburbs, small towns, and farm country.
What makes rooftop solar work here is that Pennsylvania kept the original deal. Net metering at the investor-owned utilities — PECO, PPL, Duquesne Light, and the FirstEnergy companies — credits every exported kilowatt-hour at the full retail rate, distribution charges included, and unused credits roll to your next bill; whatever remains at the May 31 annual true-up is paid out at the utility's price-to-compare. Your utility can't charge you fees that other customers don't pay. Your system also earns one Pennsylvania solar renewable energy credit (SREC) for every megawatt-hour it produces — worth about $28 apiece on average over the most recent compliance year — which an installer or aggregator can sell for you. And in the southeast, PECO customers can add a $500 utility rebate for pairing solar with a battery.
Two things to verify before signing: if you buy power from a competitive supplier rather than your utility, confirm it offers net metering (suppliers aren't required to), and rural electric co-op and borough customers are under their own utilities' terms.
