The Planes Not Panels Act would prohibit the President from using the Defense Production Act of 1950 to purchase or commit to purchasing solar panels. The Defense Production Act grants the President broad authority to direct industrial production during national emergencies, and this bill would carve out an exception specifically preventing that authority from being used for solar panel procurement. The legislation defines solar panels as crystalline silicon photovoltaic cells or modules. The bill was introduced in March 2024 and referred to the House Committee on Financial Services. No specific funding or implementation timeline is included in the legislation.
