Military Engineer Services Tender

The rate quoted shall be deemed to be included for the following as per OEM design and specifications :- Supply and erection of Solar Photovoltaic modules as per item No 01 latest edition of IEC PV module qualification test or equivalent BIS standards Poly-crystalline silicon solar cell Modules IEC 61215/IS14286. In addition, the modules must confirm to IEC 61730 Par-1- requirements for construction & Part-2-requirment for testing, for safety qualification or equivalent IS SPV Panel not less than 540 Wp including Terminal Box IP 65, bypass Diode, necessary size cable of required length with connectors. (tenderer to submit warranty for Modules-25 years) (Make in India) The total solar PV array capacity should not be less than allocated capacity (KWp) and should comprise of Mono Crystalline Silicon Solar Cell Modules of minimum 540 Wp and above wattage. Module capacity less than minimum 540wp shall not be accepted. (c)Protective devices against surges at the PV module shall be provide Low voltage drop bypass diodes shall be provided. (d) PV modules must be tested and approved by one of the IEC authorized test centers. (e) The module frame shall be made of corrosion resistant materials, preferably having anodized aluminium. Supply and erection of Ground Mounting structure made of hot top dip galvanised steel with minimum galvanization thickness of 120 microns or Aluminium alloy and suitable for SPV module specified here-in-before, including bolts,nuts,fastners,panel mounting clamps /aluminium alloy mounting arrangements suitable with M15 PCC(1:2:4) type B1 using 20 mm graded stone aggregate as per MNRE standards complete withstand 150KM wind speed and as directed. Solar on grid/grid tie Inverters of 125 KWp capacities as per MNRE Standards, outdoor type 3 phase of suitable capacities to achieve optimum efficiency. Provision of Array Junction box, with SPD combiner box as suitable for item no 01 complete all as specified and directed for 125KWp DC Power interfacing Panel/Distribution boxes outdoor type with minimum thee incoming with synchronizing facility including necessary suitable capacity MCBs,Surge Arrestors, fuse boxes, necessary earthing ,testing and commissioning. Note: Panel Board shall also suitable to distribute auxiliary power to loads like UPS,street light, module cleaning system, etc for 125KWp PVC insulated suitable size of un armoured electric power cable with stranded copper conductor of necessary size & rating as per design including necessary cable tray and lugs complete all as specified and as directed. Note: 1. The scope shall also cover design, supply, erection, testing & commissioning of LT and 11 KV Transmission Line and associate 11 KV Bay Extension at Substation. The maximum capacity for inter connection with the grid at a specific voltage level shall be as per the Distribution Code/Supply Code of the state and amended from time to time.

(a) Pre-commissioning & Commissioning of all supplied Equipment's and test running of Grid Connect Solar Power Plant as well as load trails at site . (c) Plants earthing & earthing for all equipments as directed shall generally be carried out in accordance with the requirements of IE Rules /CEA guidelines and IS: 3043. (b) Provision for Grid Islanding : In the event of a power failure on the electric grid, it is required that any independent power producing inverters attached to the grid turn off in a short period of time. This prevents the DC-to-AC inverters from continuing to feed power into small section of the grid, known as "Islands" . Powered Islands present a risk to workers who may expect the area to be unpowered, and they may also damage grid-tied equipment . The PV system shall be equipped with Islanding protection. In addition to disconnection from the grid (due to Islanding protection ) disconnection due to under and over voltage conditions shall also be provided. A manual disconnect 4-pole isolation switch beside automatic disconnection to grid would have to be provided at utility end to isolate the grid connection by the utility personnel to carry out any maintenance. the switch shall be locked by the utility personnel. (c) Any other items not specifically mentioned in the BOQ but which are required for erection, testing and commissioning and satisfactory operation of the solar power plant are deemed to be included in the scope.

Note:- (i) Pre despatch inspection shall be carried out by the authorised rep of Accepting officer before final dispatch. If any deviation is found from Schedule 'A' specifications shall be rejected. (ii) All Modules shall be delivered at site once the mounting structure are erected and tested. (iii) Cost of miscellaneous component such as termination kits lugs, shine boards, conduits, MC4 for connectors Adopter box and other connected accessories etc shall be deemed to be included in the cost of Modules.
