Rajasthan Electronics and Instruments Limited (REIL), a joint venture between the government of India and the government of Rajasthan, has floated a tender to procure 7,000 solar modules with a wattage output of 380 W to 390 W made from 72 monocrystalline or mono passivated emitter and rear cell (PERC) solar cells.
As per the tender guidelines, the modules should perform well in conditions of up to 85 per cent relative humidity and temperatures ranging from -10°C to +50°C. Wind speeds of up to 130 km per hour should not be a problem for the modules. Any supplied module’s peak power point voltage and peak power point current should not differ by more than 2 per cent from the arithmetic mean of all modules or module strings. For a 72-cell module, the glass used should be toughened low iron glass with a minimum thickness of 3.2/4.0 mm. The bid submission deadline November 19, 2021.
The winning bidders are required to furnish a performance bank guarantee for 5 per cent of the contract value. The winning bidder must deliver the modules before December 15, 2021, in three lots from the contract’s starting date. The modules must have an efficiency of at least 18 per cent. The modules should be completely resistant to potential-induced degradation and meet the requirements of the International Electrotechnical Commission (IEC)-62804. The winning bidder must provide REIL with a ten-year warranty against manufacturing faults and failures starting from the date of sale. Only Indian solar module manufacturers or their authorised dealers or distributors who are listed on the Approved List of Models and Manufacturers (ALMM) would be allowed to participate in the bidding process.
In October 2021, REIL floated a tender for rate contract manufacturing of 10,000 polycrystalline solar modules of wattage capacity greater than 330 Wp made from 72 polycrystalline solar cells. The modules should perform satisfactorily in ambient temperatures ranging from -10°C to +85°C, and should endure wind gusts of up to 170 km per hour on the panel’s surface. Each solar module shall be tested for compliance with IEC requirements, and no negative power tolerance will be tolerated. Also, 20 per cent of the tendered quantity has been earmarked for micro and small enterprise (MSE) suppliers. Of this, 4 per cent has been allocated for procurement from MSEs owned by Scheduled Caste and Scheduled Tribe entrepreneurs.
