World's Largest Solar Tree installed in West Bengal

By Tanisha Jindal

A solar tree is a metal structure that assembles the solar panels fitted on the branches. All the solar panels are connected through metal branches and thus, produce solar energy.

The CSIR-CMERI has set up the world's largest solar tree at its residential colony in Durgapur, West Bengal with a total capacity of 11.5kWp and above. There are a total of 35 Solar PV panels in a tree, each with a capacity of 330 watts. Harish Hirani, Director, CSIR-CMERI, while explaining the technology elaborated that the tree has an annual capacity to generate 12,000-14,000 units of Clean and Green Power.

The Solar tree is designed and developed in a way that each Solar PV Panel has maximum exposure to sunlight and create the least amount of shadow area beneath. And as there is least shadow area, they can be also installed in agricultural farms to run pumps, e-tractors, and tillers as the best substitute against diesel. The surplus generated power can be fed into an Energy grid providing an economic return to farmers.

This solar tree can save from releasing 10-12 tons of CO2 into the atmosphere as greenhouse gasses every year. The metal arms holding the Solar PV panels are flexible and can be adjusted as per the requirements. Energy Generation data can be monitored as well either in real-time or on a daily basis. Each solar tree costs Rs 7.5 lakhs.

Besides all this, the solar tree has the capability to incorporate IOT based features such as round the clock CCTV surveillance in agricultural fields, real-time humidity check, wind speed, rainfall prediction, and soil analytics sensors. The Agricultural Model having a solar tree in it can provide a consistent economic return and help the farmers counter the effects of the uncertain variations in Agriculture related activities, thus, giving rise to an Economic and Energy Sustainable practice in farming. Conclusively, this solar tree is Quantum Leap towards making an Energy Reliant and Carbon Negative India.
