The PV module shall be minimum with 60/144 cell of size 157 mm x 157 mm configuration with rated power of module 545W certified for solar PV module power performance tested as per IEC 61215 (Design qualification and type approval for crystalline Si modules) and BIS (PV module safety qualification testing @ 1000 V DC of higher with BIS) (b) Photovoltaic modules shall carry a performance warranty of 90% during the first 10 years and 80 % during the next 15 years. Further module cell shall have performance warranty of 97.5% during the first year of installation to get the maximum performance of the system.

(c) The module mismatch losses for modules connected to an inverter shall be less than 2% (d) The SPV module shall be made up of high transmitivity glass & front surface shall give high encapsulation gain and the module shall consisits of impact resistance , low iron and high transmission toughned glass. The module frame shall be made of corrosion resistant aluminium material which shall be electrically compatible with the structural material used for mounting the modules. (e) The module frame shall be made of Aluminium (non corrosive material) which shall be electrolytically compatible with the structural material used for mounting the modules with the required Nos of Earthing using GI strip 32 x 6 mm as earthing lead and 08 Nos of aluminium strip 25x4 mm size as required at site. (f) The terminals shall be connected to copper busbar arrangement. The junction boxes shall have suitable copper cable (as per site requirement ) entry points fitted with cable glands as per recommendations of manufacturers. (g) Copper conductor XLPE required for connection from solar power panel of system to DC/AC supply upto and connection to the existing system required to complete the solar system deemed to be included in the quoted rates.

(h) MPPT Inverter power condition unit minimum 2 MPPT (180V to 1000V ) Economical: Maximum Efficiency 98.6%, Opti track MPP tracking for best MPP Tracking efficiency, Active temperature management, Wifi communication. Simple : Three phase grid feed in ,grid voltage will be 415 volt, DC plug in system. Flexibility & future proof : DC input voltage up to 1000V, integrated grid management functions, reactive power capable. Remote Monitoring Sytem (RMS) for inverter with compatibility for both Wifi communication and GPRS communication using data sim card. The cost of data sim card and renewal of service for upto defect liabilty period shall deemed to be included in quoted rates. Make: BIS approved (j) PCC 1:2:4 type B1 (using 20 mm grade stone aggregate) for foundation /pedestal for the structure required deemed to be included in the quoted rates. (k) Supply, installation testing & commissioning of GI structure, hot dip 2mm thick for 75 KW SPV systems with proper grouting PCC 1:2:4 type B1 which can withstand high 150 km/hr wind speed so that the system can not get uprooted from ground due to high wind pressure.
