Contact your utility for current net billing enrollment status.

Net metering / billing
Net Billing (RCP)

Ohio utilities credit exported solar only at the generation portion of the rate — recently about 3–5¢/kWh, well below the full retail rate, because distribution and transmission charges are not offset — so self-consumption maximizes value.

Estimates use the average Ohio current utility rate (before solar) of $0.20/kWh (EIA, retrieved Aug 2026) and modeled solar production; individual results vary with your rate, usage, roof orientation, and shading.
