The photovoltaic pumping system is different from the traditional AC pumping system , and the photovoltaic pumping system utilizes solar cells convert solar energy into electric energy , then the photovoltaic pumping inverter drives ac motor for the pump running , and pumping up water from water well , river , lake etc areas and then transport to the destination to satisfy our requests for the water demand .

Photovoltaic arrays adopts solar radiation energy to convert it to electric power ,providing the motive power for the whole system . And the function of the solar pumping inverter is converting the DC power output from PV array to AC power to drive the pump to finalize the water pumping up as well as adjusting the output power real-timely according to the change of sunlight intensity , in this way , the system realizes the max power point tracking and the solar energy can be utilized furthest

The whole system solves the water pumping up requests perfectly , omitting the battery bank and charge controller etc equipments , so it is very economical and environmental . Since they are with the merits of low carbon , energy conversation , environmental protection etc , so they  have a broad market foreground and great social value
