In addition to the ways described in sibling responses to this question - diesel pumps suck, solar (submersible) pumps push. In practice you can't suck more than about 8 metres (in theory it's a bit more), and while there are ways you can force a ground-based pump to get water up from a deeper depth than that .. the economics work against you. A submersible pump - DC-driven by solar typically - can sit at the bottom of your bore, and push 100 metres or more upwards. No sucking required, so they're relatively simple and efficient. (My little 75mm x 500mm submersible solar pump, for example, is pushing about 5k litres per day through 600 metres of 50mm pipe, with a vertical (head) of ~40 metres from bore water level.)
