Electronics business Rajasthan Electronics & Instruments Ltd has opened a tender to supply it with 25,000 75 Wp solar modules with bidding set to close a week on Friday.
To be eligible, bidders should have a minimum of 10 MW per annum module manufacturing capacity and must have produced and supplied a cumulative 5 MW of mono or multi-crystalline products of the generation capacity specified or above during the last fiscal year.
The modules must be made into 9×4 arrays using 36 cells each. Under standard test conditions – 1000 W/m², cell temperature of 25 degrees Celsius and air mass of 1.5 AM – the products should give peak power output of a minimum of 75 W and have a cell efficiency of greater than 17% and a module efficiency of more than 15%.
The solar panel glass should be a minimum 3.2mm thick with an anodized aluminum frame having an anodizing thickness of a minimum of 15μm.
The modules must perform satisfactorily at ambient temperatures of between -10 degrees Celsius and 85 degrees Celsius and must withstand gusts of up to 170km/h on the surface of the panel.
The producer must provide a warranty against manufacturing defects of five years and six months. The modules must also be warranted for their peak output (Watt) capacity, which should not be less than 90% after 10 years and 80% after 25 years.
The modules must also be IEC 61215 (2nd edition) or BIS 14286 certified by a lab accredited by the National Accreditation Board for Testing and Calibration Laboratories or by the IEC Quality Assessment System For Electronic Components.
