Polycrystalline Solar Panel, 0.5V, 250 mAThe length and width are approximately 48.6 mm x 21 mm. Thickness is 3 mm. The open circuit voltage (Voc) I is 0.6V on a full bright sunny day.The Voc may vary slightly from vendor to vendor for this specific size.Connect 5 of these together in series and you may get close to a 3V charging rate to charge a 3V supercapacitor at around 250 mA. Be careful and don't go over the voltage rating of the supercapacitor or you may damage it.Use this ideal diode to prevent reverse current leakage from the supercapacitor to the solar panels when they get shaded or it gets dark:https://www.maximintegrated.com/en/products/analog/amplifiers/MAX40200.htmlUltra-Tiny Micropower, 1A Ideal Diode with Ultra-Low Voltage DropCurrent Switch/Ideal Diode Saves Space and Offers 10x Lower Voltage Drop Than Schottkys0.5V, 250 mA versions:https://www.aliexpress.com/item/1005002952138982.html?spm=a2g0s.8937460.0.0.4b682e0eW5jzNThttps://www.aliexpress.com/item/1005002951237285.html?spm=a2g0s.8937460.0.0.1b332e0e3F4DAV
