Consumption will be measured monthly and, in the event the net metering is negative, as when the customer’s generation system production is greater than the customer’s consumption, the net negative consumption will be treated as a credit against future electric bills of one kWh for each kWh generated above the Customer’s consumption. All monthly credits shall be accumulated against all consumption during the course of one year

Production Meter Required


Indicate all conductor sizes and insulation types, conduit sizes, fuse and circuit breaker ratings, inverter ratings, ground fault protection device (GFPD), AC and DC disconnect ratings. Specify the PV module’s nameplate short circuit current (Isc) and open circuit voltage (Voc). If disconnects, breakers, fuses, GFPD, etc. are part of a larger piece of equipment, show them as such by indicating how they are connected to the other devices and indicating their ratings. The inverter must be shown as either connected to a dedicated branch circuit with back-fed overcurrent protection (NEC 705.12(B)(1)) or connected to the supply side of the service disconnecting means (NEC 705.12(A)). The AC and DC grounding electrode conductors must be shown on the one-line diagram (NEC 690.41).

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with Lyons Municipal before you rely on this. The useful move: if an installer says you need a main panel upgrade, ask how these tap and interconnection policies were considered first.
