In West Bengal, the world’s largest ‘solar tree’ by CMERI


CMERI’s solar plant has 35 panels, each generating 330 watts of electricity.


The Central Mechanical Engineering Research Institute (CMERI) in West Bengal invented the world’s largest ‘solar tree’. Scientists here claim that according to their research, it is the largest solar plant in the world capable of generating about 11,500 watts or 11.75 kilowatts of electricity.

Harish Hirani, director of the Council of Scientific and Industrial Research’s (SCSIR), the country’s leading research institute, said the second-largest solar plant in London is capable of generating about 7.6 kilowatts of electricity.

A solar tree is a metal structure formed in the shape of a tree with solar panels attached to its branches. Those solar panels or solar panels produce solar power. CMERI’s solar plant has 35 panels, each generating 330 watts of electricity.

Harish Hirani, Director, CMERI, added, “A solar plant produces about 12,000 to 14,000 units of electricity a year without pollution. And it can’t release 10-12 tons of carbon dioxide into the atmosphere. Air pollution is much less.

The main problem in creating these solar plants, which are capable of producing huge amounts of unconventional energy, is the lack of space required. It is not possible to generate as much electricity as can be done by the solar panels scattered on the branches of these solar trees in the solar panels installed on the roof. The cost of making this solar plant at CMERI is around Rs.7 lakh.

Unconventional energy expert and Green Oscar-winning SP Gon Chowdhury said solar plants can generate many more units of electricity in a very small space. But one of the main obstacles to creating a solar tree is its capital investment. As a result, the cost of one unit of electricity generated by solar plants becomes much higher. It costs twice as much to install solar panels on the roof to make solar trees. So it costs Rs. 3.5 to produce one unit of electricity.

CMERI scientists said that solar tree panels can be used as an alternative to diesel to drive pumps, e-tractors and tillers in various agricultural sectors. And the extra electricity generated can be sent to the grid, which will then be used by farmers. According to Harish Hirani, the solar plant is a huge success in India in terms of carbon-free power generation.
