DETAILS OF THE POWER PLANTS

Solar PV modules shall be designed and manufactured to meet the same recognized standard which must have been used extensively throughout the world for more than a decade with an excellent track record of performance. SPV modules shall generate a peak power 325 Wp + 0.5 Wp or should be of higher capacity with + 0.5 Wp under STC.Each module should have two separate inter connected strings with proper by-pass diode(s). Minimum dimension of the SPV module shall be preferred.

MODULE MOUNTING STRUCTURE: Module mounting structure to be manufactured with steel angles and channels should be hot dip galvanized or spray galvanized. Size of angle 50x50x5mm angle for 31 module.

FOUNDATION: The foundation pedestals where-ever necessary shall be concrete (M-20 grade, size 300x300x300mm)

JUNCTION BOX:The junction boxes shall be made up of module cast PVC, dust and vermin proof. The terminals shall be of appropriate size; junction boxes shall have suitable cable entry with suitable glanding arrangement for both input and output cables. Suitable marking on the bus bars shall have to be provided to identify the bus bars etc.

Tools kit: Necessary maintenance tool kit (key, spanner, screwdriver), is to be provided for any immediate maintenance - two set. Make- Taparia or equivalent.

DITRIBUTION BOARDS: Distribution boards shall be used. All MCBs, Indicators, Energy Meters are to be interconnected through copper bus bar and are to be housed in a suitable sized sheet metal, enclosure. The panel board is to be grounded and for this purpose a suitable ground terminal is to be arranged. The panel board shall be coated with good quality paint. The distribution panel board shall be dust and vermin proof. The distribution panel board shall be wall mounted type and of front door opening type. The distribution panel board shall have suitable cable entry arrangement so that cable can be fastened with proper size gland loads. A distribution board shall be used for Power supply to the emergency AC from the inverter. The DB shall consist of MCB at incoming and at outgoing terminals, suitable size Copper wire are also to be supplied and installed for interconnection of DB inverter.

POWER CONDITIONING UNIT:The power conditioning unit should convert DC power produced by SPV modules, into AC power and adjust the voltage and frequency levels to suit the local grid conditions. Common Technical Specifications of the Inverter Type : IGBT based

LIGHTING PROTECTION: Each array structure of the PV yard should be grounded properly. In addition the lightening masts should also be provided inside the array field. Provision should be kept inside the array field. Provisions should be kept for shorting and grounding of the PV array at the time of maintenance work. All metal casing/shielding of the plant should be thoroughly grounded in accordance with Indian Safety Act/IEEE rules. set of 03.

LIGHTENING & OVER VOLTAGE PROTECTION: The SPV power plant should be provided with lightening and over voltage protection. The principle aim in this protection is to reduce the over voltage to a tolerable value before it reaches the PV or other subsystem components. The source of over voltage can be lightening or any other atmospheric disturbances. ESE Type lightning arrester.

JdVVNL Note :- (i) Contractor shall be fully responsible for maint of plant including all type of material required. (ii) Contractor shall be fully responsible to all type of liason with JdVVNL. Any expenditure incurred during the installation/ commissioning/ testing/ On grid connection etc included in quoted rate.
