The Solar dome was invented by the Kolkata’s solar power expert Santi Pada Gonchaudhuri. The solar dome is a cheap way of generating power by absorbing solar energy instantly and is, therefore, being touted for use in rural regions of India. Over 6,000 such solar domes have been installed mainly in the rural and tribal areas of Madhya Pradesh, Chattisgarh, Uttarakhand and Manipur. The dome can be easily fitted on a floor ceiling of a house.

The solar dome installed at the PM’s residence generates 20 watts LED light during the day and 6 watts during the night. The solar dome is again a cost-effective way of generating power using a sustainable source of energy. A unique solar dome has already been installed in the city of joy Kolkata to create awareness about sustainable renewable energy. The outer part of the dome is covered with solar modules. The energy generated by the dome is self-consumed to power the planetarium, marine aquarium and gallery which are housed inside.

According to the inventer, the houses in the European countries are being built in a way that adequate sunrays enter the homes and panels installed could capture the light. The project has received some financial aid from the union Science and Technology ministry. The ministry of science and technology and MNRE are also finding ways to fund the solar dome program. The concept is also generating green jobs, with nearly 90 people currently having hands-on learning and training in ways to install the solar dome.
