Solar pumps system

Solar pumping system becomes more and more popular, it can be applied to daily use (underground water), agriculture irrigation, forestry irrigation, desert control, pasture animal husbandry, water supply for islands, wastewater treatment engineering, and so on. In recent years, with the promotion of the utilization of newenergy resources, solar pumping systems are more and more used in municipal engineering, city centresquares, parks, tourist sites, resorts and hotels, the landscapes and fountain systems in the residentialareas.This system is composed of a solar array, a pump and a solar pumping inverter.

In recent years, with the promotion of the utilization of newenergy resources, solar pumping systems are more and more used in municipal engineering, city centresquares, parks, tourist sites, resorts and hotels, the landscapes and fountain systems in the residentialareas.This system is composed of a solar array, a pump and a solar pumping inverter. Based on the designphilosophy that it is better to store water than electricity, there is no energy storing device such as storebattery in the system.
