Solar-powered undies – Dollar Industries installs 4 MW solar array


West Bengal-based underwear manufacturer Dollar Industries has announced the commissioning of a 4 MW solar plant at its manufacturing facility in Tirupur, Tamil Nadu. The array—part of the company’s Green Mission initiative—is expected to generate 75 lakh units of electricity annually.

The solar plant will help Dollar Industries reduce costs and make its spinning unit at Tirupur sustainable and self-reliant.

With each kilogram of cotton yarn manufactured having an energy cost of INR27-28, the solar plant will provide almost half the spinning unit’s daily power. The array will also curb CO2 emissions by 9,000kg per day, according to Dollar.

Coimbatore-based Indway Power Energy commissioned the solar plant as engineering, procurement and construction services provider. 

The power generated from the array will primarily be used for the spinning unit with any excess power fed to the dyeing unit at SIPCOT Industrial Park, in Perundurai.

Dollar Industries Ltd has invested INR18 crore in the solar plant and the payback period is expected to be five years.
