Delhi’s solar policy will come into effect from April, eight months after it received the Aam Aadmi Party government’s approval.The move will not only help households avail the 30% subsidy offered by the ministry of new and renewable energy (MNRE) but also prevent dubious vendors from hawking substandard solar panels in the capital. Starting April, residents planning to install solar energy generation systems on their rooftops will receive a list of 75 government-certified vendors to choose from. “Next week, we will start accepting applications from interested people. Advertisements will also be issued in this regard. We aim to have solar panels capable of generating 75 MW of power installed at private residences and buildings run by trusts,” said Varsha Joshi, secretary (power).
