3V, 400 mA, Polycrystalline Solar PanelA good match to power my 3V, 450F super capacitor for powering near or below 3.3V microcontrollers and sensors.Results may vary from batch to batch.I measured a maximum Voc (Voltage open current) of 3.7 volts and a minimum Voc 3.4 volts after the temperature on the solar panel started rising.Isc (Short circuit current) was measured to be near ~400 mA.https://www.amazon.com/dp/B0B7RLWDT2I used the diode below to prevent reverse current leakage to the solar panels when it gets dark or they get shaded.(Thanks to the people on the Arduino forums for the suggestion).SR560 Schottky Barrier Rectifier Diode, 5A, 60V, DO-201ADBuy Link:https://www.amazon.com/dp/B079KCWPWQI get an approximate Vfd(forward voltage) drop of 0.4V using the diode above and that's just what I need to charge the supercapacitor up to 3V:3V, 450F Ultracapacitor, TPLH-3R0-450SS35X71Buy Link:https://www.digikey.com/en/products/detail/tecate-group/TPLH-3R0-450SS35X71/9930287
