This standard specifies the performance and quality requirements for solar photovoltaic (SPV) water pumping systems. It covers the three main sub-systems: the PV array, the motor-pump set, and the electronic controller, ensuring overall system reliability and water output for applications like irrigation and drinking water.
Specifies the requirements for solar photovoltaic (SPV) pumping systems used for water pumping applications, including components and performance.

Key Formulas
System Sizing Basis (Annex C): Calculation based on required hydraulic energy (flow rate Q and head H), location's average daily solar radiation, and efficiencies of pump, motor, and controller.
Practical Notes
This standard is the basis for the technical specifications of the PM-KUSUM scheme; however, always refer to the latest MNRE guidelines, which may have more stringent requirements.
Correct system sizing (Annex C) is critical. Undersizing leads to poor performance, while oversizing leads to unnecessary cost.
Ensure all components have the required test certificates and markings as per the standard to be eligible for subsidies and to ensure quality.
