Solar Installers Serving St. Louis City & County
St. Louis City and County are full of brick homes with steep or complex roofs, plus newer subdivisions in West County. We check roof structure and shading first and handle city and county permits.
Ameren Missouri serves nearly every address. Because exported power is credited at a low avoided-cost rate, we size systems to your actual usage and often recommend a battery to use more solar in the evening.
Utilities in St. Louis City & County
Ameren Missouri nets your solar production against your usage each billing period under Missouri's Net Metering and Easy Connection Act. Excess production is credited at Ameren's avoided-fuel-cost rate (currently 3.84¢/kWh in summer and 3.39¢/kWh in winter), well below the retail rate, so we size systems to offset your own usage rather than to export power.
