@teknomunk @BowsacNoodle @sickburnbro @jeffcliff @skylar The reason I say battery, is because, a decade ago, the best solar panel factory in the world, was boasting they'd finally produce a panel with slightly less energy, than it would produce over its life time. The thing is, the process of material purification purification is extremely expensive. I doubt their panel was a net gain then, and I certainly don't think the slap dash factors of the chines are producing panels any more efficiently than the Germans were.
