    Hey Everyone, I am still playing with Solar stuff and as yet have not made a great deal of useful stuff :)

    I have this 20 watt solar cell, and i want some options as to what i can do with it.

    it's specs are as follows:
    Nominal Peak Power (P max): 22.00W
    Peak Power Voltage (Vmp): 15.20V
    Peak Power Current (Imp): 1.45A
    Short Circuit Current (Isc):1.60A
    Open Circuit Voltage (Voc ):19.20V
    Minimum Power (P min):20.00W

    Looking for a few different project options, I have in mind that maybe i'll run a little 2.0Watt Compact Fluro Light. Maybe look around for a water pond pump.

    I am not sure how big a battery I could charge with this panel.

    thanks everyone :D
