Ltd.) --- Case Study · Industrial · Rooftop # Super Smelters: 1980.3 kWp Rooftop Solar Plant A 1980.3 kWp rooftop solar power plant, about 2 MW, on the open roofs of Super Smelters Ltd., described by the local press as the largest industrial unit in the Jamuria industrial area of West Bengal. The Project ## About the Super Smelters, West Bengal project The plant was built in collaboration with Tata Power Solar, with Arrays Ingenieria as implementation partner. It was inaugurated by Super Smelters' director, Sanjay Singhania, with Lt. Gen. Ashish Ranjan Prasad (Retd) of Arrays Ingenieria present. Super Smelters issued Arrays Ingenieria a letter of appreciation for the project, and the inauguration was covered by Sanmarg and other Hindi dailies. In 2024 Tata Power Solar engaged Arrays Ingenieria for the installation & commissioning of the 1980 kW sheet-roof plant, the BOS materials and additional cabling, cable trays and earth excavation, the earthing strip, and the supply and service of the module cleaning system. ### Our scope of work - Installation & commissioning of the 1980 kW sheet-roof plant - Balance-of-system (BOS) materials and additional cabling - Cable trays and earth excavation - Earthing strip and self-drilling fasteners - Module cleaning system: supply and services - Testing and commissioning ### In the news [Newspaper: **Sanmarg**1980.3 kWp solar plant installed for environmental protection at Super Smelters](https://arraysingenieria.com/recognition/#sanmarg-supersmelters)[Newspaper: **Hindi daily, Jamuria**1980.3 kWp rooftop solar power plant inaugurated at Super Smelters](https://arraysingenieria.com/recognition/#supersmelters-rooftop) ### Photos ## Project facts Capacity: **1980.3 kWp (about 2 MW)** Plant type: **Industrial rooftop** Location: **Jamuria (Asansol), West Bengal** Client: **Super Smelters Ltd.** Partner / programme: **Tata Power Solar Systems Ltd.
