The Ministry of New and Renewable Energy (MNRE) released the results of its state rooftop solar attractiveness index (SARAL). Karnataka ranked the highest on this index and emerged as the best state for setting up rooftop solar projects. The other top-rated states include Telangana, Gujarat and Andhra Pradesh. These states, along with Karnataka, received a rating of A++ on their evaluation for rooftop development attractiveness. Meanwhile, Jammu and Kashmir was ranked last. According to the MNRE, the index will introduce a healthy competition among states which will catalyse the development in the solar rooftop segment. The best practices of the top ranking states can serve as examples for the rest.
