Verizon Data Services India and the Indian Institute of Technology (IIT), Madras, have provided off-grid solar systems to 300 houses in rural villages in Nalgonda district, Telangana.
The systems, which do not include inverters, pair a 125 W solar panel with a 1 kWh storage battery. They operate on a 48 V (DC) internal distribution line and can be used to power fans, lights and mobile phone chargers.
Cygni Energy installed the systems in the villages of Ramunigandla Thanda, Kesya Thanda, Jogi Thanda and Mantriya Thanda, according to The Economic Times. The villages are located about 100 km south of Hyderabad, the state capital.
The IIT developed the off-grid PV systems, which do not feature inverters. Cygni said that it chose DC systems over AC equipment because they are more efficient.
Verizon Data Services India provided INR 7.5 million ($117,000) of financing, in cooperation with the Southern Power Distribution Company of Telangana (TSSPDCL) and Rural Electrification Corp.
In mid-2016, the IIT collaborated with the Indian Ministry of Power to electrified 4000 rural houses in Rajasthan as part of the “GO-SOLAR DC” plan.
