Hello, I currently have a 2S 2P solar configuration or (2 connected in series and then those are connected to another 2 in parallel. Each solar panel is 5v. I will have pictures below. But pretty much I am able to get around 8v with good light in my 2S 2P configuration, and then I use that voltage to charge a 1000uf 50v electrolytic capacitor to around 6v (checking with my multimeter) then I try to connect the output of the capacitor to a small toy 6v motor( the type you get in basic Arduino kits). With that setup I am only able to see a very small movement of the motor then the capacitor is discharged, then I added another 1000uf capacitor in parallel and charged them both to 6v and then connected the output to the motor and was able to get a little more movement but still barely any.
I am trying to learn more about electronics and what I am trying to understand is - without the capacitors and just the panel and the motor and I am not able to get any movement because I am limited by the very small 2 ma output from my solar configuration(which I checked with my multimeter) so that is nowhere near enough to drive a motor even connected in parallel as I have it. My question is when I am using my capacitor i let it charge to 6v. So does it have 1000uf capacitance at 6v or how does that work? I know that capacitors store charge on separate plates, but how does capacitance relate to built up current? or does it not work like that? I also tested with a timer and saw that with the same voltage it take way longer to charge a 1000uf capacitor then it does to charge a 10uf capacitor. so should the capacitor be thought of as energy stored? or what would be a good analogy?
I know this is a lot of questions but I am just trying to wrap my head around this. Thanks
