Net metering / billing
Net Billing (RCP)

PPL Electric moved new solar customers to hourly market-based crediting in July 2026: exported energy is valued at a rate tied to hourly wholesale prices (recently around 12–14¢/kWh, below the retail rate) rather than at full retail, so self-consumption maximizes value.

Estimates use the average Pennsylvania current utility rate (before solar) of $0.22/kWh (EIA, retrieved Aug 2026) and modeled solar production; individual results vary with your rate, usage, roof orientation, and shading.
