Many MindedUS solar factories can now cover module demand, but cells and wafers lag
US factories can now produce more finished solar modules than the country installs in a year. That is the headline from the latest Clean Investment Monitor data, which Canary Media's Julian Spector charted on 6 November 2026. Installations last year came to 47.9 GW of direct current capacity, and solar is now the top choice for new US power plants.
Domestic manufacturing had nearly disappeared before recovering in recent years, helped by federal incentives and higher tariffs on foreign products. If every announced project, plus those under construction or being commissioned, is completed, module capacity would grow by about 83%.
Modules are only the last step. Upstream sit photovoltaic cells, silicon wafers and processed polysilicon. Cells have been the most successful of these so far: after several factory openings this year, domestic plants can make up to 19.5 GW of cells a year. Capacity would grow further if projects now finishing construction all come online.
This matters for abundance because solar is the main source of new US power. A home-built supply chain means less exposure to import disruptions for that supply. It also gives the country a firmer base for adding cheap electricity and for producing the goods themselves. The gap between module capacity and the smaller cell capacity shows that the dependence has shifted upstream and not yet ended.
Two caveats apply. The 83% figure assumes every announced and in-progress project is finished. Our source text also cuts off mid-sentence, so we lack its details on wafers, polysilicon and the final cell-capacity projection. Those are the numbers to watch, and Canary Media's full piece is the place to check.
