Central Electronics Limited (CEL), a public sector enterprise, has floated a tender for the supply of solar photovoltaic ribbons by approved bidders.

Bidders must make an earnest money deposit of ₹13,500 (~$185). The last date for the submission of bids is February 5, 2021. Shipments must be delivered in staggered lots up to August 31, 2021.

CEL said that only original manufacturers or their authorized representatives are eligible to place bids. They must have previously supplied at least 40% of the tendered quantity of ribbons to solar manufacturers in the last two years.

Unapproved vendors who are technically qualified are expected to submit a sample of at least 5 kilograms of solar photovoltaic ribbons that meet CEL’s specifications.

CEL last invited bids from eligible and approved bidders for the supply of solar ribbons in August 2020. Before this, it had invited online technical and financial bids from eligible bidders to supply 1 ton of solar photovoltaic ribbons.

According to Mercom’s India Solar Tender Tracker, CEL has floated tenders for about 6.93 million multicrystalline cells as of Jan 2021.
