The Central Mechanical Engineering Research Institute (CSIR-CMERI) has set up a solar tree at its residential colony in Durgapur, West Bengal. This is the largest solar tree across the world, with a capacity of over 11.5 kWp. Each tree is made of 35 solar panels and has a capacity of 330 W. The tree is capable of generating 12,000-14,000 kWh of electric power during a year. Each solar tree will cost Rs 750,000. The inclination of the arms holding the PV modules are flexible and can be adjusted. This feature is not available in rooftop solar systems. The solar trees can be substituted with price-volatile fossil fuels for agricultural use. Each solar tree has the potential to save 10-12 tonnes of carbon emissions as compared to fossil fuel, and the surplus power generated can be fed into the power grid.
