Small Monocrystalline 5.5volt 80milliamp solar panels,ideal for educational use battery charging, powering small motors and experimenting, these can be joined together in series or parallel to make larger panels with higher voltage or current as required which can be used for either battery charging or powering leds,fans,motors,waterpumps etc,these are also very useful used singularly for twin or triple aa or aaa battery charging in solar garden lights as they are a lot more powerful than the solar panels fitted to most solar lights these days which are generally only 30- 40 milliamps,they can also be used to make an odd sized panel or a panel of a certain voltage,a good use could be for battery charging on model aircraft,boats,etc due to their small size and light weight,specifications are as follows Voltage, 5.5volts, Current 90milliamps Size, 65mm x 65mm Weight, 15 grammes Constructed using resin & pcb making them very tough and waterproof, ideal for outdoor use. Copper Solder tags on rear which can be easily soldered to. Each panel is protected by a thin plastic removeable slip to help prevent them from getting scratched on the front during transit.
