  • Let's learn about Super Capacitors! (A Practical Guide To Super Capacitors)

    Hi. I am using a 15W solar panel and letting it feed a BUCK CONVERTER to charge USB devices. When a cloud passes the buck converter shuts down and a button must be depressed to turn it back on. Id like to use a capacitor to maintain the "ON" state of the buck converter, which is this: has a wide input range but my cap will be charged from around 15V-22V and at max about .9 amps. Id imagine you would recommend a 25V Cap. What is the max amperage that could charge a cap. like that? What would be the ideal farad value and # in parallel that would allow for longer "cloudy moments"? thanks so much, very helpful instructable.
