In December, a provision was cut from the omnibus spending bill, a 1.4-trillion-dollar package that was negotiated by the White House, Senate Republicans, and House Democrats and signed by President Donald Trump. The provision, originally conceived in the Energy Policy Act of 2005, allowed for a 30% household tax credit for the cost of installing a residential solar-electricity system. In 2015, Congress extended that credit through 2019. Now, without new legislation passed to redeem the credit, it will drop to 26% this year, 22% in 2021, and nothing in 2022.
