| 1 | Supply, Installation & Commissioning of SOLAR PV MODULE/ARRAY:The Solar Photovoltaic (SPV) modules supplied and to be installed for the 10 kW on-grid rooftop solar power plant shall be made of high-efficiency mono-crystalline silicon solar cells (415W-540W). The interconnected cells shall be vacuum laminated with tempered glass to withstand adverse environmental and climatic conditions. The module frame shall be fabricated from corrosion-resistant anodized aluminium, suitable for long-term outdoor installation. Minimum clearance between the lower edge of the module and finished roof level shall be 300 mm for RCC roof and 75 mm for tin shed roof. The SPV modules shall be duly certified as per IEC 61215 / IS 14286, IEC 61730 Part I & II, IEC 61701 (Salt Mist Corrosion) and IEC 62804 (PID test) from accredited certification agencies. Each module shall carry a minimum 25 years performance warranty, guaranteeing at least 80% of the rated output at the end of 25 years. Module-to-module earthing shall be provided using 1C × 2.5 sq.mm copper cable, ensuring proper electrical safety and system reliability. The modules shall be of MNRE-approved make, suitable for grid-connected solar power plants under the net-metering scheme. [Make : TATA POWER / PANASONIC / LUBI] | | 2 | SITC of On-Grid Power Conditioning Unit (PCU) / Solar Inverter – 10 kWSITC of 10 kW On-Grid Solar Inverter (PCU) of MNRE-approved make, 3-Phase, 415 V AC, grid-interactive type, complete with remote online monitoring system, suitable for operation under WBSEDCL net-metering scheme as per WBERC regulations. The inverter shall have rated AC output capacity of 10 kW, maximum DC input voltage ≥1000 V, DC operating voltage range 200–850 V, MPPT operating range 480–850 V, and minimum start-up voltage 250 V DC. The inverter shall be provided with anti-islanding protection, zero reverse power flow, DC input overload current protection, and in-built protections against over/under voltage, over current, short circuit, earth fault and over-temperature. Standby losses shall be <1.5 W. Communication interfaces shall include Ethernet / RS-485 / Modbus / USB, with MC4 type DC connectors. The inverter shall be complete in all respects including installation, testing, commissioning and synchronization with the DISCOM grid. [Warrenty -10Years] [Make : TATA POWER / PANASONIC / LUBI or any OEM authorized Brand] | | 3 | Supply, Installation & Commissioning of Solar Hot Dip GI Mounting Structure, as per the IS Specifications Designing of Module Mounting Structure (MMS): During Structural design following points must be include but not limited to the following: a. Theremust be sufficient gaps between the rows of the panels and all precautions to be taken to avoid any shading on the panels. Minimum 500mm clearance should be maintained in between roof and module. b. The module alignment and tilt angle shall be calculated to provide the maximum annual energy output. This shall be decided based on the location of array installation. c. The structure shall be designed toallow easy replacement of any module and shall be in line with site requirement. d. The mounting structure shall be designed for simple mechanical and electrical installation. It shall support SPV modules at a given orientation, absorb and transfer the mechanical loads to the base properly. e. The mounting steel structure shall be as per latest BIS 2062 (amended up to\ date). f. The array structure shall be so designed that it will occupy minimum space without sacrificing the output from SPV panels at the same time. g. All fasteners, nuts, bolts shall be of stainless steel of grade SS 304. h. The support structure & foundation shall be so designed to withstand wind load of the location as given in relevant Indian code for wind (IS 875 Part III, latest edition). i. IS 800-2007 shall be followed for structural design. Accordingly STAAD output of the design is to be submitted. j. Galvanization of the structural members shall conform to IS: 4759. The quality of zinc shall conform to IS: 209 and IS: 2629. All galvanized materials shall withstand tests as per IS: 2633. Arrangement of testing shall be made by the contractor. | | 4 | Supply, Installation & Commissioning of Cu bonded Earthing Rod of 3Mtr / 17.6mm dia | | 5 | Supply, Installation & Commissioning Cu Spike Type Lightening Arrestor | | 6 | Suppl, Installation & Commissioning of 4Sqmm Solar LSZH Cu Tinned DC Cable (Type I) 36amps | | 7 | Supply, Installation & Commissioning of 16sqmm Cu Flex Cable | | 8 | Supply, Installation & Commissioning of 210sqmm 4C Al Aurmord Cable | | 9 | Supply, Installation & Commissioning GI Strip 25X3 for Earthing | | 10 | Supply, Installation & Commissioning Array Junction Box | | 11 | Supply, Installation & Commissioning of ACDB | | 12 | Supply, Installation & Commissioning of BOS (MC 4 Connector, Lugs, Nut Bolts, Fastners etc) Please Enable Macros to View BoQ information |
