This initiative, managed by the Tamil Nadu Energy Development Agency (TEDA), supports the nationwide Rooftop Solar Programme Phase-II led by the Ministry of New and Renewable Energy (MNRE)(https://mnre.gov.in/), Government of India. 

Together, these programs make solar power more affordable, efficient and sustainable for Tamil Nadu households.
