Amorphous vs Crystalline Solar Panels: What''s the Difference?
Due to the higher efficiency of crystalline silicon solar cells, amorphous silicon cells are less favored for large installations and thus considered a more specialty product. That said, they are also the least expensive to produce, coming in at just $0.45-$0.53 per watt of power produced in a typical amorphous silicon panel.
