I chose a solar panel 5 5v it gives more on direct sunshine but 6v is ok too.

Meerkat supercapacitor charger is compact and versatile designed to support common 2 5v and 2 7v edlc supercapacitors.
Wide input voltage ranges from 4 5 v to 16 v and adjustable maximum power point provides the capability to use various power supplies including solar panels.
These supercapacitor charger devices come in both linear and switching topologies and offer input or output current limiting automatic cell balancing and a range of protection features that make them uniquely suited to supercap charging.

Supercapacitor charger on hardware.
I am looking for suggestions for devices to charge a single supercap from a solar panel.
A supercapacitor sc also called an ultracapacitor is a high capacity capacitor with a capacitance value much higher than other capacitors but with lower voltage limits that bridges the gap between electrolytic capacitors and rechargeable batteries it typically stores 10 to 100 times more energy per unit volume or mass than electrolytic capacitors can accept and deliver charge much.
The panel size will be 1 2w and the supercap is a 3000f 2 5v unit.
The circuit is pretty simple and can be constructed on a breadboard but i decided to use a perf board so that i can reuse the circuit in future in every attempt to charge my super capacitor.
Here we need two things.
Then i selected a size big enough to cover the box cover and it is 300ma.
If this is the wrong forum please let me know which one i should use.

Normally it reaches 5 2v when charged.
Linear supercap charger with current limited ideal diode and v i monitor data sheet reliability data 1 pdf.
I also intend to use it along with solar panel for portable projects hence tried building it as small and rigid as.
It uses an additional diode so that a nearly empty supercap can still be charged if the solar panel voltage is below the 1 5v minimum for the max40200 ideal diode.
This needs to be tested but the idea is that the max40200 would dominate once higher input voltages are reached.
