The traditional electricity driven pump for pumping water needs to pull wires to water, the distance would be a few kilometers even further, but power loss is going to be worse with distance expansion. Comparing to it, solar pumping system is very flexible. It can be installed near the water source, wherever it locates, as long as there is enough sunshine, then it works stably as the system fully automatic operation without people on duty. It can keep working for 25 years as one-off investment.
