Chemtrols Solar Private Limited has unveiled India's First MW scale PV-Diesel Hybrid Solar Power plant in Tamil Nadu. A spinning mill in Tirupur District of Tamil Nadu has the distinction of having a MegaWatt (MW) Scale, Roof Mounted, Grid-Connected Solar power plant with unique DG synchronization capabilities, the first of its kind in India, and only the second in the World. The 1 MW Solar plant installed on the sloping roof of Alpine Knits (India) Private Limited at Palladam in Tirupur has been designed, engineered and constructed on a turnkey basis by Chemtrols Solar Private Limited, headquartered in Mumbai.

The Rooftop Solar plant synchronizes with the incoming 11KV utility grid and provides energy to the spinning mill for captive consumption during daytime. Importantly, even when the utility grid is not available during frequent power cuts, this solar plant has the capability to synchronize with the in-house 1.25MVA Diesel Generator to provide up to 65% of the energy required by the Alpine Knits factory, thanks to the recent 'Fuel Saver' technology developed by SMA Solar Technology AG of Germany, the global market leader in the field of Solar Inverters and related technologies.

During grid failure, when the DG set is put into operation, the 'Fuel Saver' device constantly monitors the DG set electrical parameters, the available load at the factory and optimizes the Solar Power Plant output to provide substantial fuel (diesel) saving at any point in time. The Fuel Saver also provides protection to the DG Set and to the Solar Power Plant against reverse power as both are power generating devices.
