The front busbar must be at least 0.8±0.2 mm wide and back busbar 1.5±0.3 mm
Only indigenous manufacturers with multicrystalline solar cell production capacity of a minimum 50 MW per annum are eligible to apply. They are required to certify that modules manufactured using the supplied cells will conform to IEC 61215/IS14286, IEC 61730 and IEC 62804.
