The Rajasthan Electronics and Instruments Limited (REIL) has floated a tender to procure 7,000 solar modules of minimum 380 W to 390 W made from 72 monocrystalline or mono PERC solar cells. The winning bidder must deliver the modules in three tranches by December 15, 2021, from the start of the contract. The bid submission deadline is November 1, 2021.
As per the tender guidelines, to be eligible, the solar modules must function well in temperatures ranging from -10°C to +50°C, as well as survive harsh climatic conditions such as wind speeds of up to 130 km/h on the panel surface. International Electrotechnical Standards should be followed by all modules (IEC- 62804). There would be no tolerance for negative power. The modules should be completely resistant to potential-induced degradation and have a service life of more than 25 years. Modules should have a minimum efficiency of over 18 per cent. The glass used in modules should have a high transmission, low iron content, and be toughened to a thickness of 3.2 mm to 4.0 mm. The bending of the glass must be less than 0.3 per cent.
Further, the winning bidder must also give a ten-year warranty, as well as free replacement or repair in the event of manufacturing defects. At the end of 10 years, the peak watt capacity of the solar module should be at least 90 per cent, and at the end of 25 years, it should be at least 80 per cent.
Earlier this month, REIL floated a tender for 7,000 solar modules with a minimum power output of 380 W made up of 72 monocrystalline solar cells. The bid submission deadline is October 31, 2021. As per the tender guidelines, to participate in the bidding process, only Class-I and Class-II local suppliers, as per Make in India order 2017 will be eligible. The tender will, however, allow eligible small and small enterprises to participate. The average turnover criterion is waived for small enterprises, as well as original equipment manufacturers.
