SLD Reqs

The connection for the Solar system will need to be placed on the load side of the main breaker of the service panel.


If the Owner wishes to directly meter the energy production of their Generating Facility, Owner shall install a meter socket and associated wiring to allow measurement of energy production from the Generating Facility. The meter socket shall meet WMIDD’s Electric Service Specifications.


There shall be no load connected between the dedicated meter and the panel breaker feeding the solar electric system.


The meter socket shall be located next to the Owner’s existing WMIDD meter.


The owner shall provide and install a meter to measure energy production from the Generating Facility.

Install Reqs

Wellton-Mohawk only supplies the main revenue meter, which will be changed to a bi-directional meter at the time of inspection and testing.

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with WMIDD - Wellton-Mohawk Irrigation & Drainage District 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.
