0.5V, 100 mA Solar Panel Soldering Fixture and Case

This particular model has:
5x 0.5V, 100mA solar panels in series with a max peak Voc (Voltage open circuit) of 2.999 Volts so it doesn't destroy a 3V supercapacitor that I will charge with this.

I used the case as a fixture to help solder the panels together. Brass inserts are used for the M3 screws to fasten to them and close the solar panels in a case.

There are 250 mA versions of these solar panels that I will use next.

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:
