Net metering / billing
Net Billing (RCP)

New Jersey requires full 1:1 retail-rate net metering at all four of its investor-owned utilities, so exported energy offsets consumption at the full retail rate with monthly rollover; excess at the annual true-up is paid at the wholesale avoided-cost rate. This estimate assumes a system sized to your annual usage.

Estimates use the average New Jersey current utility rate (before solar) of $0.23/kWh (EIA, retrieved Aug 2026) and modeled solar production; individual results vary with your rate, usage, roof orientation, and shading.
