KOLKATA, 27 NOV.: The roof top installation of solar panel seems to have become a hit with city academicians as they turned in large numbers to the national workshop on roof top and small PV power plants organised by the Renewable Energy School of the National Institute for Bioprocessing Research and Training (NBIRT) and center of excellence for green energy and sensor system, Bengal Engineering and Science University (Besu), at a city hotel today.
The state IT minister, Mr Debesh Das, inaugurated the workshop and said that promoting solar power would enable the country to have “energy independence”. He also said that the solar valley in Andal would enable integrator units to set up units there.
More than 41 city schools and colleges participated in the workshop and have shown eagerness to install solar panels in their campus. Several city colleges like Gurudas College and Asutosh College have already switched to solar power.
Mr Rupayan Bhattacharya, principal of Gurudas College, said that the 5 MW capacity panel installed in their campus suffices 60 per cent of the power consumption. “We need 7.2 KW of electricity and the five solar panels installed in save 60 per cent of our electricity bills. Also, solar panels are easier to maintain,” said Mr Bhattacharya. The cost of installation of the cells was Rs 10 lakh given by the local MLA.
Dr SP Gon Chowdhury, director of the West Bengal Green Energy Development Corporation Limited (WBGEDCL), said that the country seemed to missed the point that small rooftop plants of capacity 2 KW to 100 KW has huge potential. Also, through the regulatory committee, a net metering tariff order has come out which would bring down the electricity bill.
“If the initial installation cost of the unit is contributed by MPLAD fund or by a company as its corporate social responsibility (CSR), the savings in the electricity bill would become direct profit for the institute,” said Dr Gon Chowdhury.
Prof Ajoy Roy, Vice-Chancellor of Besu, said that if all of the sunlight in two hours is converted into electricity, that would be able to the energy demand of the country for one year. However, efficiency is a problem when it comes to solar cells and research is the need of the hour. He also said that land is a problem in the state, it is much more easier to go for roof top installations.
