HI @gnappi - Only reason for the 6V system is that originally I was missing a battery and a charge controller. But I see your point that a 12V system might work better, and it seems like all I need do is get a larger solar panel and a larger battery. Am I correct? Also, I am just learning...

Hello folks. Wanted to give you an update on my little project. I purchased the following: - 6V 12AH battery from Amazon (Power-Sonic Rechargeable Sealed Lead Acid Battery PS-6100 6V 12.0 AH @ 20-hr. 6V 11.5 AH @ 10-hr) - 5A Waterproof Solar Charge Controller 6V 12V Auto from Amazon) - BUD...

Thanks for the clarification, @snoobler. I take it that a single 6V battery will do the trick. The one I am looking at is "Power-Sonic Rechargeable Sealed Lead Acid Battery PS-6100 6V 12.0 AH @ 20-hr. 6V 11.5 AH @ 10-hr" (found on Amazon).

You mention battery dipping below 12.1V... The battery voltage requirement is 6V. Can you clarify? Thanks.

Hi @snoobler: Been thinking a bit more about your guidance. The highest AH battery I found is 6V 12AH. So I would need to get two of those batteries and put them in parallel to get 6V 24AH (otherwise I risk burning out the pump?)? Thanks!

@Forbisher: I haven't purchased the other two panels yet. The first one I got came as a kit so I paid about USD 30 for the panel, the submersible pump and a 16-ft length of wire. The panel is in a plastic frame with a screw-in barrel-type connector (not sure how to describe this type of...

@snoobler: Thanks! I will go ahead and play with this information. Regards.

@snoobler: Thanks for the analysis! What you suggest makes sense, so I will get a couple more of those panels (Do I need to put them is series or in parallel?).

@snoobler: panel is 3.5W; submersible pump is rated at 6-9V @87gph with a 45 in head

Ah, this is great! So, a Walmart SCC + a 6V battery should do it? Any thoughts on my second question - re: adding a couple of 9V panels in parallel, but pointing eastwards and westwards? Thinking that would allow me to get sunlight throughout the day, and be sufficient to power the pump and...

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...
