My amorphous panels no longer produce current even in sun. These cheap solar panels only last a few years with continual usage. The one seI got from amazon fall of 2007, another spring of 2008. 4 out of 8 have failed, no light from the testor. The 8 panels have outside 24/7 rain snow ice conditions on out building roof, Buyer beware!
