The Vipra Multipurpose Souharda Credit Cooperative Society, located at Vinobha Nagar here, has not only attained self-sufficiency in its electricity needs by successfully tapping the solar energy, but also planned to project it as a model for revenue generation.

Frequent power outages in recent times had affected the day-to-day functioning of the cooperative society. A.R. Prasanna Kumar, president of the society, told The Hindu that when the duration of power cut was too long, even the uninterrupted power supply (UPS) system installed at the society used to stop functioning. As a solution to this problem, it was decided to tap the solar energy.

Two mini-solar energy plants of 5-kW capacity each were installed on the roof top of the building of the society. An on-grid inverter that converts direct current (DC) into alternating current (AC) was also installed.

After catering to the local load, the surplus power was imported to the grid.

The cost of installation for the two mini-solar plants was Rs 10.5 lakh and they were commissioned in September. Around 1,400 (700x2) units of power is being generated from the two plants, every month.

The average monthly electricity consumption of the society was around 400 units and the remaining 1,000 units were sold to the Mangalore Electricity Supply Company (Mescom at Rs. 9.56 a unit. Apart from saving the electricity charges of around Rs 4,000 a month, the society was earning around Rs. 9,000 a month by selling the surplus power.

To ensure optimum power generation during low-light conditions, copper indium diselenide solar cells have been installed in the panels. Barring the wiping of dust that gets accumulated on solar panels, there was no other maintenance cost involved, he said.
