ITI Limited, a public sector undertaking under the Department of Telecommunications, has floated a tender to supply 23,50,080 polycrystalline solar cells.

The total tender value is ₹110.10 million (~$1.43 million). The entire quantity must be supplied in three lots against each purchase order.

The last date to submit bids is May 16, 2022. Bids will be opened on the next day.

Bidders must submit an earnest money deposit (EMD) of 2% of the tender value or a maximum of ₹500,000 (~$6,523). The EMD of the successful bidders will be converted into a security deposit. Successful bidders must submit a security deposit balance of 5% of the order value or a maximum of ₹1 million (~$13,047) before placing the purchase order.

The cells must have a wattage of 4.57W. Their dimensions must be 157 x 157 ± 0.25 mm and thickness of 200 μm ± 20 μm. They must also have a silicon nitride anti-reflective coating. The cells must have a busbar difference of 31.2 mm ± 0.25 mm. They must have 18.60% efficiency in standard test conditions. The cells must have a fill factor of 80%, be either light blue, blue, dark blue or indigo.

The cells should be free of visual defects like broken or chipped edges, micro-cracks, pinholes, discontinuity of metal printing liens, spots, spillages or smears, color variations, and non-uniform printing lines.

The quantity will be distributed in the ratio of 60:40 to 70:30 between the lowest bidder (L1) and L2 if the order is to be given to two bidders. If the order is to be placed on three selected bidders, the guiding ratio would be 50:30:20 for L1, L2, and L3 bidders. More than three bidders may be considered in case of larger volume or because of capacity restriction.

If the bidder fails to deliver the material on schedule, liquidated damages equivalent to 0.5% of the tender value per week will be charged for the first four weeks, and 0.7% of the tender value will be charged per week beyond four weeks.

Earlier, ITI Limited had floated a tender to supply 531,360 multicrystalline solar cells.
