Polycrystalline Solar Panel, 0.5V, 400 mA

The length and width are approximately 59 mm x 37 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 400 mA.
Be careful and don't go over the voltage rating of the supercapacitor or you may damage it.

Caution serious injury or death may occur if you don't know how to use the supercapacitor!
i.e. it short circuits.

Use this ideal diode to prevent reverse current leakage from the supercapacitor to the solar panels when they get shaded or it gets dark:
