More than 400 clean energy companies are urging congressional leaders to take legislative action. The Solar Energy Industries Association is calling for a settlement that includes a long-term extension of the Solar Investment Tax Credit (ITC) and a stand-alone energy storage credit. The group is also calling for ratification of the Solar Manufacturing in America Act (SEMA). SEMA will provide a tax credit of 11 cents/watt for integrated modules, 4 cents/watt for batteries, and $12/m2 for batteries. Meter. wafers, and $3/kg of polysilicon. The bill's provisions were contained in the now-defunct Build Back Better Act. Experts suggest it may take 2-3 years to build a domestic solar supply chain to meet U.S. demand.
