Ministry of environment and ministry of renewable energy has taken initiatives to increase the solar power generation in India. In Haryana, it is now mandatory (from September 2015) to install roof top solar plant for every building premises which is built on equal to or more than 500 sq yards. The size of the solar plant depends on the load of the entire building. i.e. 5% of the total load. (A fine of 10000 to 1000000 can be charged against failure of the same)
It is being planned to install and produce 2 GW solar power in Delhi NCR region by 2025. The first phase of installation is targeted to be complete by 2019 for 1 GW solar electricity.
