In fact, very most of the farmland without power supply, normally irrigated by rain or artificial operation from the river or well. Accordingly, with the deterioration of the climate, the rainfall decreases with each passing day, agricultural irrigation can only rely on human. Solar pumping system is to rely on the electricity for solar powered to drive the water pump to work, drawing the water from the river or the well, thereby substantially reducing the amount of labor personnel.

 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.
