The company that made mine is called Powerfilm.Available all over the internet.Comes in 5 watt on up.I use a 14 volt panel(15 watt panel) with a 12 Volt,8 station,battery charging station like you would use in your car (car cig adapter).Cut the plugs off and add my own.Works great,even works without direct sunlight.

A person could charge batteries directly with a smaller panel(5 watt or so) but you would have to time them or keep checking the voltage every hour or so.Or you would run the risk of cooking them to death (NiMH) or worse (Lithium) FIRE SCARECROW???

You can power a cell phone,mp3 player,gps,most all small electronics directly off of the panel.The 15 watt panel will directly run anything up to a 1.2 amp draw,up to 12 volts..
