3V, 400 mA, Polycrystalline Solar Panel · 模型 105148
3V, 400 mA, Polycrystalline Solar Panel A 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/B0B7RLWDT2 I 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). https://grabcad.com/library/sr560-schottky-barrier-rectifier-diode-5a-60v-do-201ad-1 Buy Link: https://www.amazon.com/dp/B079KCWPWQ I 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: https://grabcad.com/library/3v-450f-ultracapacitor-tplh-3r0-450ss35x71-1 Buy Link: https://www.digikey.com/en/products/detail/tecate-group/TPLH-3R0-450SS35X71/9930287
