They are the cheapest panels but they are less efficient than mono- and polycrystalline panels (efficiency of 6-8%) and they require twice the amount of surface. On the other hand, amorphous silicon absorbs light differently and assures a better power output compared to crystalline silicon because it produces energy even in low-light conditions.
