CSIR-CMERI develops world's largest solar tree

CSIR-CMERI has developed the world’s largest solar tree, which has an installed capacity of more than 11.5 kWp and an annual capacity of 12,000-14,000 units. The solar tree is installed at CSIR-CMERI Residential Colony, Durgapur.

“The installed capacity of the solar tree is above 11.5 kWp. It has the annual capacity to generate 12,000-14,000 units of clean and green power,” Harish Hirani, director, CSIR-CMERI, said while elaborating on the technology. 
The solar tree has been designed in a manner to ensure least amount of shadow area beneath and maximum exposure of each solar PV panel to sunlight. There are a total of 35 solar PV panels in each tree with a capacity of 330 Wp each. The inclination of the arms holding the solar PV panels are flexible and can be adjusted as per requirement a feature not available in roof-mounted solar facilities. The energy generation data can be monitored either real-time or on daily basis.
“The CSIR-CMERI developed solar tree besides being the world’s largest also has certain customisable features for application at diverse sites. The solar trees were designed in a manner to ensure minimum shadow area, thus potentially making these solar trees available for widespread usage in agricultural activities such as high capacity pumps, e-tractors and e-power tillers,” Hirani explained.
“These solar trees can be aligned with agriculture for substituting price-volatile fossil fuels. Each solar tree has the potential to save 10-12 tonnes of CO2 emissions that fossil fuels used would have released into the atmosphere as greenhouse gases. Besides, the surplus power generated can be fed into an energy grid.
“This agricultural model can provide a consistent economic return and help the farmers counter the effects of the uncertain variations in agriculture related activities, thus, making farming an economic and energy sustainable practice,” he added.
Each Solar Tree will cost Rs7.5 lakh and interested MSMEs can align their business model with the Pradhan Mantri Kisan Urja Suraksha evem Utthan Mahabhiyan (PM KUSUM) Scheme for farmers, for developing a renewable energy based energy grid.
The solar tree has the capability to incorporate IOT based features, ie, round-the-clock CCTV surveillance in agricultural fields, real-time humidity, wind speed, rainfall prediction and soil analytics sensors. The CSIR-CMERI developed solar powered e-Suvidha Kiosks may also be connected to the solar trees for real-time access to the vast majority of agricultural database as well as to the eNAM, ie, National Agricultural MarketPlace for instant and real-time access to unified online market.
