Super Capacitor Solar Powered Energy Bank DIY Project is similar to solar powered power banks but instead of li-ion batteries, it uses super capacitors. The super capacitors are used because they are more comfortable with non-stop charging and discharging cycles, they last longer than batteries, having larger power efficiency therefore it can be used for a very long time. Some disadvantages include its heavier, it’s a lot costlier than batteries and has less capacity.
This device has four important parts: 6 d-cell sized super capacitors, charging electronics, discharging electronics and a 5.5v solar panel. The parts include the project box, six 500 2.7v super capacitors, small voltmeter, solar panel, USB socket as well as other parts.
The first step is to set up the solar box cover by first soldering the schotky diode and two wires to the panel, then placing the panel over the box cover and drill holes to take the wires out. Pass the wires through the holes and glue them in place, then place the solar panel over the cover and peg it.
Next is to set up the super capacitor banks by connecting them in parallel with wires, then attaching the longer wires to connect them to the longer electronics. Then fixing the LED along with the LED circuit. Then mount the USB circuit, and connect the voltmeter circuit through the push button to minimize power usage, then glue the voltmeter on the inside of the box. Connect everything else and insert the board into the box and close it – next is to test it.
