- The modules must be made into 9×4 arrays using 36 cells each
- The solar panel glass should be a minimum 3.2mm thick
- The panel should have an anodized aluminum frame having an anodizing thickness of a minimum of 15μm
- Performance should be satisfactorily at ambient temperatures of between -10 degrees Celsius and 85 degrees celsius
- It should withstand gusts of up to 170km/h on the surface of the panel
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.
PV Magazine reported that in order 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.
Technical criteria
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 a peak power output of a minimum of 75 W and have a cell efficiency of greater than 17 per cent and a module efficiency of more than 15 per cent.
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 per cent after 10 years and 80 per cent 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.
