CEL has issued a tender, seeking eligible bidders/ vendors for the supply of 1000 kgs of solar PV ribbon of width 5 mm and thickness 0.3 mm.

The Central Electronics Limited (CEL) has issued a tender, seeking eligible bidders/ vendors for the supply of 1000 kgs of solar photovoltaic (PV) ribbon of width 5 mm and thickness 0.3 mm. As per the tender, this is a limited enquiry only for the approved vendors of CEL. In case, a new vendor wants to participate and supply similar goods to CEL, they can enrol themselves through the vendor registration form.

The date of opening of the bids has been set for May 4, 2020. The tender stated that the bids submitted by the supplier should be valid for a minimum period of 90 days from this date. The supply of the entire quantity will be based on the needs of CEL and will be completed before December 31, 2020.

As per the tender, only original equipment manufacturers (OEMs) are allowed to submit quotations, along with their authorised representatives. Vendors who are technically qualified but are unapproved are expected to provide 5 kg samples of PV ribbon that meet CEL specifications for approval.

CEL stated that the ribbons must be 5 mm in width and 0.3 mm in thickness with a base material of high conductive annealed ETP copper ~99.90 Cu. The resistance of the PV ribbon must not be more than 15 ohm/km at 20 degrees Celsius. The coating must consist of 60 percent tin and 40 percent lead on each side of the strip and must be at least 15-20 microns thick.

The photovoltaics manufacturer also specified that the ribbons must be packed in 5 kg 10-S spools and that the spools should be shrink-wrapped or vacuum-packed into cardboard boxes with EP foam inserts. The ribbons must be smooth and uniform, and any branches or streaks of exposed copper are not acceptable.

In January, CEL had extended the bid submission deadline for its tender for setting up of grid-connected solar PV rooftop power plants of cumulative capacity of 1.6 MW ranging from 10 kWp to 50 kWp in various Government Buildings in Tamil Nadu. The deadline for bid submission has been extended from March 26, 2020, to April 20, 2020.
