Foldable photovoltaic module

Such unapparent small, I take the folded 34 Watt module out of the backpack. With 2 kg weight, it produces with 2 hours sunshine the same amount of energy like an equal heavy lead acid battery.

6 hours sunshine brings the same amount of energy like an equal heavy Lithium Phospaht battery.
