Manufacturers source most solar panels from outside the U.S. One way to find out where a solar panel comes from is to check where its individual parts are sourced. You can
Leading U.S. solar panel manufacturers include First Solar, Qcells, Silfab Solar, Jinko Solar, and Canadian Solar's U.S. operations. Their factories in states like Ohio, Georgia, Texas, Florida, and South Carolina produce high-efficiency solar panels made in the USA that qualify for federal incentives.

In solar panels, the glass, encapsulant and backsheet are important for protecting solar silicon cells from damage and harmful exposure, such as harsh weather. Protectant manufacturing follows the same process as most other solar panel parts.
