Solar Panel Subsidy in West Bengal, 2023

West Bengal is a pioneer in solar technology in India. Government-owned WEBEL was one of the first manufacturers of solar energy panels in the country. It is mandatory for all large housing societies in West Bengal, (having a total contract demand of more than 500 kW) to install solar rooftop systems to meet a minimum of 1.5% of their total electrical load by solar energy. The subsidies are applicable as per SECI guidelines.

How & how much subsidy on solar can be availed? 

Subsidy/Support is available from Central Government through MNRE.

The subsidy available on the installation of grid-connected solar rooftop power plants is 30% of the benchmark cost. Government institutions including PSUs shall not be eligible for the subsidy. Instead, they will be given achievement-linked incentives/awards. All residential and institutional buildings such as schools, health institutions, etc. and the social sector can avail CFA.
