A cotton mill in the south of India has installed a PV system, enabling it to reduce its reliance on a diesel generator during power grid outages.
Mumbai-based Chemtrols Solar has installed an hybrid system on the roof of the factory in a suburb of Tirupur in Tamil Nadu, which includes SMA Sunny Tripower inverters and an SMA Fuel Save Controller.
Lengthy power cuts in the area are an everyday occurrence, and the new 1MW system will reduce the need to use the diesel generator at these times.
Dhananjay Nandedkar, assistant to the vice president of solar projects at Chemtrols Solar, said: “For factories that suffer power outages and are dependent on diesel generators for their power supply, a hybrid system is the perfect solution as it increases the utilisation of the PV power plant significantly and thus reduces payback time.”
Until now, the cotton mill operator, Alpine Knits, had used a diesel generator to supply power during the power outages, which led to increasing production costs.
The installation in Palladam is SMA's second hybrid system to use the SMA Fuel Save solution, following the installation of a system last year in a South African chrome ore mine.
Roland Grebe, chief technology officer at SMA, said that diesel generators currently provide more than 20GW of power to industry in India. He added that with more than 300 sunny days a year, India was in a prime location for PV power.
He said the firm was planning further installations in collaboration with Chemtrols.
“In sunny regions, the SMA Fuel Save Solution is an economical and ecological alternative to increasing diesel prices and high CO2 emissions,” he added.
