MNRE Seeks Views on Draft Specifications & Testing Procedure for Universal Solar Pump Controller

The MNRE has proposed to consider the use of USPC to increase the utility of solar PV system installed for solar water pumps. Therefore, it has formulated the draft specifications and testing procedure for USPC.

After inviting suggestions on draft guidelines for lab testing of storage batteries and inverters, the Ministry of New & Renewable Energy (MNRE) has now sought views from stakeholders on draft specifications and testing procedure for Universal Solar Pump Controller (USPC).

Recently, the government approved a scheme for farmers for installation of solar pumps and grid-connected solar power plants. The administrative approval for the scheme was issued by the Ministry on March 08, 2019.

The MNRE has proposed to consider the use of USPC to increase the utility of solar PV system installed for solar water pumps. Therefore, it has formulated the draft specifications and testing procedure for USPC.

Thus, interested stakeholders can provide their comments/suggestions/views latest by April 19, 2019 at [email protected].

As per MNRE, here’re a few proposed technical specification for standalone and on-grid application:

The scope of work includes:

(a) To install USPC with SPV modules, structure and pump set, in short solar system for irrigation purpose with capabilities to perform multiple auxiliary functions like energizing agrarian equipment: Apple grading and polishing system, Wheat (grain) floar grinding machine / Aata chakki, Cutter/chaff, Deep-fridger / cold storage, Blower fan for cleaning of grains, any other standard voltage (400/415V) three phase motor. These equipment are ranging from capacity 3 HP to 10 HP. USPC should have robust system protection features, remote fault monitoring etc.

(b) To install the USPC based solar system as above plus capabilities to export power to the grid when pumping is not in operation.

If in case farmer wishes to apportion the power between Motor/Pump set and Grid: Algorithm i.e. Software should provide that facility.

This kind of situation may arise when the farmer’s requirement for irrigation (discharge) can be met by less power than installed power.

This will save groundwater depletion, crop loss due to overwatering will be avoided and thus raise productivity and result into higher income for the farmer, besides un used SPV power fed to the grid will further raise farmer’s income.
