To encourage the adoption of renewable energy resources nationwide, the U.S. government has reauthorized (though 2019) the substantial (30%) tax credit to those homeowners installing solar energy systems. In addition to that federal incentive, Columbia’s Water & Light Department (CW&L) offers a generous 50 cent per Watt rebate on solar installations. CW&L is the only electric utility in Missouri that offers such a rebate.

Considering these dual financial benefits, what might it cost a homeowner to install a typical 5,000 Watt (5 kW) residential solar system in Columbia Water and Light’s service area?
