I think that every one has forgoten that solar panels are an industrial "item" in the real world. They are not made from coal dust, They are made with silicone. I have seen some expirmental versions that use raspbarrys, But that would be weird for a mod.
IC2 already has silicone in it, It should replace coal dust. It would be silly to leave the resipe as is.
anyone else, if you leave a smug comment like its as good as it is, just cause. Then you are apathetic towards ic2 and you chould shut up and go play vanilla!!!
