Plans & docs

Site Plan Reqs
  • Disconnect must be on same building as utility meter.
  • Call out Utility Meter, MSP, Fused AC Disconnect and Inverter.
  • Legend labels alone are insufficient.
  • Show street name.
  • If a project includes PV Solar AND a Tesla Powerwall, the project's DC size will be the sum of panels and Tesla Powerwall. For example, if panels put out 4.5kW and a Tesla Powerwall puts out 5kW, the DC size on the SITE PLAN and LINE DIAGRAM should be 9.5kW.

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with WE Energies 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.
