Solar Photovoltaic Module conversion efficiency shall not be less than 16.5%. PV modules used in solar power plants/ systems must be warranted for their output peak watt capacity, which should not be less than 90% at the end of 10 years and 80% at the end of 25 years. Make: As per latest ALMM list and approved by Engineer Incharge

b)Power Conditioning Unit (PCU)/Inverter of String type Grid tie 350-800V DC Input voltage range and 400VAC, three phase,4wire,50Hz+/-2.5Hz, output voltage suitable to generate AC Power with efficiency not less than 97%, totalharmonic distortionless than 3% and suitable for ambient temperature from 0 to 50 degreeC. The PCU shall adjust the voltage and frequency level to suit the Grid Voltage Frequency. Inverters shall have RS 485 / GSM and Ethernet provision. Warranty for Inverter shall be minimum 7 years. Make: Growatt / Sungrow / Dye / Havells / Hitachi / Fronius as per Engineer Incharge.

c) Data Monitoring System complete with accessories compatible with the existing Data monitoring system.

d) Fixing of Array junction box & Main junction box with IP65 protection and termination arrangement for incoming and outgoing cable along with glands,lugs and other accessories etc. as required.e) Lightning and surge voltage protection.

e) Lightning and surge voltage protection.

f) Connections & Interconnections by supplying & fixing required size XLPE insulated copper conductor 1.1 kV grade armoured power and control cables between solar modules,main power cable to grid supply PCU unit alongwith supplying & fixing of necessary channel/ conduit lugs and other accessories etc.as required.

g) Construction of pedestal for solar panel - the rate inclusive of providing and laying in position specified grade of reinforced cement concrete, including the cost of centering and shuttering using film coated plywood, finishing and reinforcement - All work up to terrace level of ESB : using 1:1.5:3 (1 cement : 1.5 coarse manufactured sand (zone-III): 3 graded stone aggregate 20 mm nominal size). The rate also inclusive of providing a box type reinforcement using 8 mm Thermo-Mechanically Treated bars of grade Fe-415 or higher grade at a spacing of 15cm c/c. Before laying the concrete a layer of LDPE sheet of 400 micron or higher thickness shall be laid over the existing surface. The existing weathering tiles / waterproofing treatment shall not be damaged. The rate also inclusive charges towards lead and lifting of materials, necessary scaffolding, fixing charges of foundation bolts, de-shuttering, curing, finishing the surface and applying two coats of paint with exterior emulsion paint etc., complete.

System Installation:

System shall be installed by a Electrical A Grade Licensed Contractor. If the vendor is possessing Electrical A Grade License, they shall carry out the installation work on their own. The Contractor shall obtain CEA Approval for the plants installed.

The contractor shall take instructions from IITM/consultant , prepare and submit shop drawings for space frame installation, solar panels , cabling , piping etc. along with specification sheets for all equipments for approval before procurement of any material. FAT mandatory for Solar panels & Inverters.

Foundation pedestals shall be as per the attached drawing.

The Contractor shall carry out survey of the buildings offered and submit Shadow Analysis report, Array Layout and SLD for each building offered. The capacity given is of cumulative one, and IITM shall provide various available buildings for installation of Solar PV systems.
