Hi everyone, newbie here.
I have about 400m of polythene pipe on my shed roof to help heat our inground pool. I'm now looking for a solar pump to circulate the water. I've tries a circulation pump but have had untold issues with air coming in the system and the pump not priming. Now looking at a submersible pump. Found a 12VDC 2000 GPH Bilge pump on Trademe – 8amp and will pump to 6m, ample for what I need. What I'm wondering is, would anyone have any experience on what size solar PV panel I'd need to power the pump. (From what I can gather volt x amp=watts so in this case, 12v x 8amp=96watt?), so thinking a 100w panel might work?. And what else I'd need to hook the pump and panel up.
I like the idea of PV as you don't need a solar controller to turn the pump on and off.
I've asked some questions on Trademe, but most traders aren't knowledgeable about what they sell. Hoping someone here might be able to give me some useful advise?
That would be much appreciated!
Thanks heaps everyone.
