Relating to: net metering for rooftop solar energy systems.

AB 901 establishes rules for net metering of rooftop solar energy systems in Wisconsin. It directly affects homeowners and businesses with solar installations by setting capacity limits (30 kW for residential, 500 kW for commercial) and requiring advanced metering for grid interconnection. The bill mandates that electric providers credit customers 100% of the retail electricity rate for excess power sent to the grid, with credits expiring March 31 annually and transferring to new property owners upon sale. It also allows providers to reduce credits to 90% if solar adoption exceeds 10% in their service area, while maintaining minimum billing standards for solar customers.
