A Rs 75 lakh CSR project is now providing assured power supply round-the-clock to 300 households in four hamlets of Devarakonda Mandal. The Indian Institute of Technology, Madras (IIT-M) has developed this solar technology, which was transferred to and commercialized by Cygni Energy Private limited, an IIT-M incubated firm, which also carried out the installations.

Verizon Data Services India provided financial assistance under Corporate Social Responsibility (CSR) for this project.

Ramunigundla Thanda, Kesya Thanda, Jogi Thanda and Mantriya Thanda are four rural hamlets of Devarakonda Mandal predominantly dependent upon paddy and cotton farming for livelihoods, are about 100kms from Hyderabad. These hamlets together have around 300 households, most of which fall under 'low income' category. They have been suffering from frequent power outages, especially during monsoons and 'peak-demand' times.

The inverterless system, comprising a 125Wp Solar Panel, a 1kWh battery, an inverterless 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.

The project was implemented under the aegis of Professor Ashok Jhunjhunwala, principal advisor, Ministries of Power and New and Renewable Energy, Government of India, and Professor (On Sabbatical), IIT-M.

"Today, millions of homes in India either do not have grid connectivity, or suffer from power outages for large fraction of the day. This is a very serious challenge as majority of these homes fall under low-income category and cannot afford power even with some subsidy. Solar DC Inverterless technology deployed in the 300 homes of Devarakonda, Telangana tackles this problem and shows how, with a small 125W solar panel on the home rooftops, the dynamics of electricity in India could be transformed. This project heralds India's move towards a solar powered future, without compromising on efficiency or affordability," said Jhunjhunwala.
