The Solar Energy Corporation of India (SECI) has floated a tender for the supply of 870 MWp of domestic content requirement-compliant solar modules for projects in Radhanesda, Gujarat, under Tranche III of the Central Public Sector Undertaking Scheme.

Bids must be submitted by March 10, 2026. Bids will be opened on the same day.

The supply will be divided into three packages of 290 MWp each. Bidders can quote for a minimum of one package and a maximum of three. SECI can add up to 17 MWp of additional capacity to a single package at the time of the award.

It can also place repeat orders for 91 MWp of solar cells and modules for projects in Ramagiri, Andhra Pradesh, and 172.5 MWp for projects in Chitradurga, Karnataka.

Bidders must furnish an earnest money deposit of ₹132 million (~$1.45 million) for one package, ₹264 million (~$3 million) for two packages, and ₹396 million (~$4.36 million) for three packages. They must also submit a processing fee of ₹25,000 (~$275.75).

Selected bidders must submit a contract performance security of 10% of the total order cost.

The scope of work entails the manufacturing, testing, packing, forwarding, and transportation of solar modules and cells.

The solar modules must have a width of 1134 mm ± 2 mm and be registered with the Bureau of Indian Standards. Only modules and cells compliant with the Approved List of Models and Manufacturers List I and II must be used.

The solar modules must be suitable for use with semi-automatic or fully automatic robotic cleaning systems. They must be suitable for deployment on horizontal single-axis tracking systems in a one-in-portrait configuration.

The modules must use monocrystalline silicon TOPCon cells, their front and back sides must be made of tempered glass, and they must have aluminum frames.

The modules must have an efficiency of at least 21.65%. They must have a minimum power rating of 585 Wp under standard test conditions. The solar modules must  have a minimum temperature coefficient of power of -0.30%/°C.

Their annual power degradation must not exceed 1% in the first year and 0.4% from the second year.

The supply order must be executed within 12 months. Delay in supply will incur liquidated damages of 0.5% per week of the unexecuted value of the contract price, capped at 5%.

Bidders must have operational solar module manufacturing facilities. They must have a minimum annual module manufacturing capacity of 435 MWp per quoted package.

Bidders must have an average annual turnover of ₹1.98 billion (~$21.86 million) per quoted package in the last three financial years.  They must have a positive net worth in the previous financial year.

Bidders must have a minimum working capital of ₹1.65 billion (~$18.22 million) per quoted package.
