Hi experts. I am new to this forum, so I beg your indulgence.
I have a 9V solar panel driving a 6V pump for a solar water fountain. This simple set-up works just fine.
What I want to do is add a battery to it along with a charge controller so that I can have the pump run when there is no sunlight.
While I understand the basic principles, I do not understand how to size the charge controller and the battery properly. I would love it if I could get some guidance on this.
Furthermore, the single panel is fixed pointing southwards, so there are certain times of the day when the panel receives marginal light from the sun. I was wondering if I could add two more 9V panels (in parallel), with the two additional panels angled eastwards and westwards - the idea being that I would get sufficient sunlight throughout the day to power the pump. Is this a feasible idea or should I just stick with a charge controller/battery configuration?
Appreciate the feedback and guidance.
Regards,
Lane
