As solar technology evolves to keep up with the increasing adoption to help lower manufacturing costs and increase the efficiency of solar modules, Indian solar module manufacturers have been leaning towards the latest TOPCon (Tunnel Oxide Passivated Contact) module technology over its other mainstream rival – HJT (Heterojunction). In the Indian solar market, where the p-type mono PERC is well established, manufacturers are looking at the next big technology to replace it to achieve higher efficiency rates.
