Monocrystalline vs Polycrystalline Solar Panel: What''s the …
The Czochralski process is energy intensive, requiring high heat (2,574 F). Ingots up to 6 ft. long and 18 in. wide result. Prior to 2005, circular solar wafers cut directly from the cylindrical ingots were formed. Now, most ingots undergo trimming into "pseudo-square" bricks to reduce waste and costs (see schematic below).
