Everything you need to know about plug-in balcony solar in Michigan: legal status, tracked bills, statutory wattage limits, utility interconnection rules, and expected monthly solar production.
Current Disposition: Balcony solar bill pending
Michigan has no law authorizing plug-in or balcony solar yet. HB 5764, introduced March 19, 2026, would exempt plug-in photovoltaic systems of up to 1,200 watts from the distributed generation program and interconnection requirements, and bar utilities from requiring approval or charging fees. It is in the House Committee on Energy. Small distributed generation interconnection is governed by Michigan Public Service Commission (MPSC) rules under R 460.901a through R 460.1026 (Michigan Interconnection and Distributed Generation Standards, MIXDG). Level 1 review applies to certified inverter-based projects up to 20 kW. Public Act 235 of 2023 raised the distributed generation program cap from 1% to 10% of a utility's average in-state peak load for the preceding 5 calendar years.
