| Before you can even start designing your system, you need to know how high your pump will have to lift the water. For every 2.3 feet of lift, your pump will see 1 pound per square inch of pressure. Pumps can push water up hundreds of feet, but are very bad at pulling it. The highest distance at which any pump can pull water up into itself is about 20 feet at sea level, and decreases by about 1 foot per 1000 feet of elevation above sea level.
After you know your lift requirements, you can start looking into pumps and panels. You'll also need to know how much water you'll need per day. The best solar pumping systems don't use batteries at all -- your water storage tank can be your 'battery' if it's big enough to get you through a few days of no sun. Linear current boosters (LCBs) can be used so your pump will still function on overcast days and partial sun. And a pump controller with float switches can be used to make the system automatic.
