ITI Limited, a public sector undertaking under the Department of Telecommunication, has floated a tender for the supply of 1.845 million polycrystalline solar cells with a minimum wattage output of 4.62 W.

The estimated value of the tender is ₹116.2 million (~$1.45 million). The entire quantity must be supplied in three lots against each purchase order.

The last date to submit bids is July 29, 2022. Bids will be opened the following day.

Bidders must submit an earnest money deposit (EMD) of 2% of the tender value or a maximum of ₹500,000 (~$6,260). 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 (~$12,520) before placing the purchase order.

Bidders will also be required to deposit a security amount at 5% of the order value or a maximum of ₹ 1 million before placement of the purchase order. The security deposit will be returned to the vendor within 30 days after the successful execution of the purchase order.

The tender is for the supply of five busbar polycrystalline silicon solar cells that are 157 x 157 ± 0.25 mm in dimension. The thickness of the solar cells should be 200 +/- 20 µm.

The cells must also have a silicon nitride anti-reflective coating. They must have a busbar distance of 31.2 mm ± 0.25 mm. The solar cells must have 18.20% efficiency in standard test conditions. They must have a fill factor of 80%, and 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.

Vendors must deliver the material to the ITI stores in Naini.

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

If the supplier fails to deliver the material or part thereof as per the delivery schedule, a sum equivalent to 0.5% per week for the first four weeks and 0.7% per week thereafter as liquidated damages will apply.

In April this year, ITI floated a tender to supply 2,350,080 polycrystalline solar cells.

Earlier, ITI had floated a tender for the supply of 531,360 multicrystalline solar cells.
