A solar photovoltaic (SPV) water pumping system consists of a PV array, a DC/AC surface mounted/ submersible/ floating motor pump set, electronics, if any, interconnect cables and an "On-Off" switch. PV Array is mounted on a suitable structure with a provision of tracking. Electronics could include Maximum Power Point Tracker (MPPT), Inverter and Controls/Protections. Storage batteries will not constitute a part of the SPV Water Pumping System.
Following types of motor pump sets could be used in the SPV water pumping systems:
I. Surface mounted DC motor pump-set
II. Submersible DC motor pump set
III. Submersible AC motor pump set
IV. Floating DC motor pump set
V. Any other type of motor pump set after approval from Test Centers of the Ministry.
