Supply , transport , installation and commissioning of Solar PV installation for water pumping system with fixed structure consisting of solar panels framed in anodized aluminium frame mounted on stable hot dipped galvanized (with 80 micron thickness) mild steel structure of sufficient strength which can withstand load of modules and high wind velocities upto 150 Km/hr, having RCC foundation designed against all possible loads (Dead, Live and imposed load). Modules supplied with the SPV system should have certificate as per IEC 61215 specification or equivalent National or International standards and must be interconnected with 4/6 sq.mm cables routed in PVC conduits properly fitted along the G.I structure to provide a good aesthetic view. Modules must qualify to IEC 61730 part I and part II for safety qualification testing. The power output of individual PV modules used in the PV array, under STC, should be a minimum of 250 Watts peak, with adequate provision for measurement tolerances. Solar cells should be crystalline silicon cell with min. efficiency of 14% and fill factor more than 70%, should be laminated between sheet of -Ethylene Vinyl Acetate (EVA) and high transmissivity 3.2mm tempered glass including appropriate DC to AC inverter and power controlling unit (protected with IP65 class enclosure) with MPPT technology to run at low sunshine and minimum 5 hours a day run with all necessary accessories suitable for solar + grid operation and including all protections of AC induction motor pump. There should be a display of all measurable parameters including storing of data at a set interval and transfer it in a pendive thru USB port . There should also be provision of interfacing GPRS based data transmission. (The rate is inclusive of manufacturer's warranty and comprehensive maintenance for 1st year and comprehensive maintenace for 4 years beyond Ist year)
