Supply , Erection , Commissioning and testing of Submersible solar AC Pump to meet 1.75 lps discharge and 100 mtr dynamic head coupled with submersible motor 5 HP of MNRE approved Solar AC pump of reputed make i.e KSB/ Lubi/ Kirloskar/or equivalent. The manufacturers of pumps should self-certify that, the pump and all external parts of motor used in submersible pump which are in contact with water and i/c carriage of material within all leads lifts and as directed by the Engineer-in-Charge.

P/F and testing of SOLAR PUMP CONTROLLER (ELECTRONICS AND PROTECTIONS)with Maximum Power Point Tracker (MPPT) should be included to optimally use the Solar panel and maximize the water discharge. The inverter must have IP 54 protection or must be housed in a cabinet having at least IP54 protection. Adequate protections should be incorporated against dry operation of motor pump set, lightning, hails and storms. Full protection against open circuit, accidental short circuit and reverse polarity should be provided and i/c carriage of material within all leads lifts and as directed by the Engineer-in-Charge.

Supplying, installation and testing of PV ARRAY: The SPV water pumping system should be operated with a PV array .Sufficient number of modules in series and parallel could be used to obtain the required PV array power output. Use of PV modules with higher power output is preferred. a. Indigenously produced PV module (s) containing mono/ multi crystalline silicon solar cells should be used in the PV array for the SPV Water Pumping systems. b. Modules supplied with the SPV water pumping systems should have certificate as per IEC 61215 specifications or equivalent National or International/ Standards. c. Modules must qualify to IEC 61730 Part I and II for safety qualification testing. d. The efficiency of the PV modules should be minimum 14% and fill factor should be more than 70%. e. The terminal box on the module should have a provision for “Opening” for replacing the cable, if required. f. There should be a Name Plate fixed inside the module which will give: Name of the Manufacturer or Distinctive Logo, Model Number , Serial Number, Year of manufacture and i/c carriage of material within all leads lifts and as directed by the Engineer-in-Charge.

Supplying , Instalation and testing of MOUNTING STRUCTURES AND TRACKING SYSTEM, The PV modules should be mounted on metallic structures of adequate strength and appropriate design, with 10 feet clearance from ground, which can withstand load of modules and high wind velocities up to 150 km per hour. The support structure used in the pumping system should be hot dip galvanized iron with minimum 80 micron thickness. and i/c carriage of material within all leads lifts and as directed by the Engineer-in-Charge.

Providing earthing to all equipment to be provided as per IS 3043 (1987) A single Earth pit preparation and connectivity to all equipment with 25x3 GI strip and i/c carriage of material within all leads lifts and as directed by the Engineer-in-Charge.

OTHER ASSESSORIES/ISOLATION SWITCH AND WIRES: A good reliable switch/MCCB suitable for DC / AC use is to be provided with the motor pump set with enclosure. b. Sufficient length of cable should be provided for inter-connection between the PV array and the motor Pump sets. c. Providing vertical pipe to accomodate submersible pump and motor set inside/outside of existing stroage tank i/c carriage of material within all leads lifts and as directed by the Engineer-in-Charge.
