Due to innefficiences you'll need at least double that amount of power. I
have some new, unbreakable 20 watt panels if you need them (Uni-Solar) for
$125 each. Then you'll need a cheap inverter ($50) at walmart and a pair of
golfcart batteries. I reccommend trojan t-105's @ about $50-60 each, easily
availble locally.
