Indian Institute of Technology, Madras (IIT Madras) and Verizon Data Services India have come together to take solar technology to rural Telangana. IIT Madras, in collaboration with Southern Power Distribution Company of Telangana Limited (TSSPDCL) and Rural Electrification Corporation, has taken up this project to provide uninterrupted power using solar technology to 300 households spread across four hamlets in rural Telangana.
IIT Madras developed this Solar Technology, which was technology transferred to and commercialized by Cygni Energy Private limited, an IIT Madras-incubated firm, which also carried out the installations. Verizon provided financial assistance of Rs.75 lakh under Corporate Social Responsibility (CSR) for this project.
Ramunigundla Thanda, Kesya Thanda, Jogi Thanda and Mantriya Thanda are four rural hamlets of Devarakonda Mandal in Nalgonda District, Telangana. Predominantly dependent upon paddy and cotton farming for livelihoods, the hamlets are about 100 kms from Hyderabad, located on Nagarjunsagar Road near Mallepalli.
These hamlets together have around 300 households, most of which fall under the “Low- Income” category. They have been suffering from frequent power outages, especially during monsoons and “peak-demand” times.
The Inverter-less System, comprising a 125W Solar Panel, a 1kWh battery, an Inverter-less controller unit and DC loads operating on a 48V DC internal distribution line, were installed in all houses. It powers a DC fan, a DC tube light, two DC bulbs, a DC mobile charger, a DC power socket and a remote controller to operate the fan and tube light.
Installations were completed by June 2017 and everything has been working flawlessly. The performance and health of all the installed systems are being monitored remotely, with data being collected via mobile phones and synchronized to a central server.
The project was implemented under the aegis of Prof. Ashok Jhunjhunwala, Principal Advisor, Ministries of Power and New and Renewable Energy, Government of India, and Professor (on Sabbatical), IIT Madras.
Commenting on the project, Kalyani Sekar, Vice-President & Managing Director, Verizon Data Services India, said, “At Verizon, our commitment to empower communities around us is rooted in the firm belief that technology has the power to make lives better. Verizon India’s collaboration with IIT Madras to implement the Inverter-less Solar System for “near off-grid” areas in Telangana are a reaffirmation that we share our success with the community to make the world in which we work better than it was yesterday.”
