Hi there,
I am an electronics hobbyst and am trying to build a stable source of current from a series of solarcells in order to feed a secondary battery which would hold the stable voltage source in the end.
this battery would be responsible for feeding the energy supply to the circuit that the solar cell is not able to deliver during night hours.
The power source must be at least 9v high. But as far as I have seen series connected solar cells would attaint that pretty easily. The point is to conserve that energy once it has been supplied to the battery.
I am not familiar at all with such batteries, I presume they must be rechargeable batteries, so in a way and forgive my ignorance, sort of huge capacitors. And due to the instability of the power source, a diode would have to be placed in between in order not to supply back to the solar cell the energy, because of a superior voltage decrease in the solar cell with respect to the capacitor/battery.
So in the end I would have a set of series connected solar cells in order to add-up a given voltage source, then a diode connected in series (or rectificator bridge, but the solar source is not of AC nature is it???, it's basically unstable), and finally also after the diode in series connected the battery/capacitor. After that I would have the load for the circuit connected to the battery/capacitor.
This is a very introductory first attain for accomplishing this. I am still not focusing on how to enable/disable the circuit on a given current level for the battery/capacitor. For the time being I only want to accomplish that this battery/capacitor is able to store that energy in order to stabilise the current in my circuit.
Don't know if there are any AC circuits dependent on solar energy, but as you may presume, this is a full DC circuit.
In order to help understand I provide a quick draft of what I mean (drawn by hand : sorry!!!!). In the draft I have included the possibility to include a power dependent source, but that's a mistake so please omit that.
Any thoughts are greatly welcome.
Many thanks in advance for your help.
