The recent ‘Approved List of Models and Manufacturers’ (ALMM) rules published by the Ministry of New and Renewable Energy set 19% as the minimum efficiency for the modules to be listed. The minimum efficiency for modules used in utility/grid-scale power projects is set at 20%; for rooftop solar and solar pumping projects, it is 19.5%, and for solar lighting, 19%. Although it does not directly ban, it effectively eliminates polycrystalline modules, whose efficiencies have peaked at 17-18% from being listed in the ALMM going forward.
