Solar PV Panels 1.SPV MONO PERC Mono-facial solar panels to be supplied shall have a declared output of 500-550 Watt peak. The number of modules to be supplied will be as per the calculation; for 50kW. 2. The Hi-efficiency Bifacial TOPCon panel to be supplied, shall have a declared output of 650-715 Watt peak. The number of modules to be supplied will be as per calculation; for another 50kW. • Warranties: The MONO-PERC monofacial solar panels must be warranted for output wattage, which should not be less than 90% at the end of 10 years and not less than 80% at the end of 27 years; whereas the Bifacial TOPcon panels must be warranted for output wattage, which should not be less than 94% at the end of 12 years and not less than 85% at the end of 30 years. Including Installations Other aspects are as per tender - 100KW (Nos as per tender)

MODULE MOUNTING STRUCTURE (FIXED) 1. There are four types of structures required: two fixed (25kW each) and two single (1-D) trackers (25kW each) based on the type of solar panel. 2. The hilly terrain should be considered for structure design and tilt angle calculations as per the site's requirement. 3. MS Galvanized mounting structure cold formed members 2mm (or more) thick with a galvanizing coating of 85 microns is to be used as per requirements of this project and maximum nos. of modules is to be installed in min. area. Including Installation Other aspects are as per tender - 100KW (Nos as per tender)

SOLAR INVERTER (grid Connected) 1. Solar inverter shall be grid interactive in nature and mainly consist of dual MPPT (with Multiple string inputs) controller, inverter of rating 20 to 50 kWp, 3 phase, 415 V, IP 65/66/67 each, associated control and protection devices etc. all integrated. It shall provide necessary protections for Grid Synchronization and Data Logging/Monitoring . The inverter shall have communication protocol RS485 over Modbus/Ethernet/Wi-Fi for remote monitoring. The inverter should convert DC power produced by the PV modules into AC power and must synchronize automatically its AC output to the exact AC Voltage and frequency of Grid. 2. Inverters should be PID enabled. 3. The DC energy produced shall be utilized to maximum and supplied to the bus for inverting to AC voltage to extract maximum energy from solar array and provide 3-ph, 415V AC (-10% to +15%), 50+/- 3% Hz. to synchronize with the grid. a) The inverter shall be of very high quality having efficiency not less than 98% and shall be capable of running in integrated mode. Including Installations Other aspects are as per tender - 100KW (Nos as per tender)
