Solar water pump system advice needed
I'm looking to build a simple (and cheap) solar pump systemn to slowly fill a large tank. The water source is a spring holding pond and the 2500gal tank is about 200ft away at +125ft vertical elevation. I don't need a lot of GPM since the tank will be a large reserve. The tank will have a float valve so the pump will need a pressure shut off switch. The above ground pump will not need to syphone more than 8ft. Can anyone recommend a simple 12V pump and pole mounted panel set-up? I was looking at the shurflo pumps but need help pairing one up with a panel for my application. Also would a battery with voltage regulator give me a little extra on cloudy days?
