~280 amps at 5 volts??? O.o

Pretty sure that should be milli-amps, otherwise you're generating a ludicrous amount of power from that panel. :-)

Otherwise, cool info. There is power (ha-ha) in transforming one form of energy into another at will, although there will always be at least some parasitic loss in that process from a mechanical/electronic device to do so.

Imagine if we could build solar panels that approach the efficiency of a tree leaf? That would be something.
