500kW Solar Installation at Mahashakti Narayani Polytex LLP by SolarLogix
SolarLogix successfully designed and executed a 500 kW industrial rooftop solar power plant for Mahashakti Narayani Polytex LLP, a manufacturing unit engaged in poly pack production, located in West Burdwan, West Bengal.
The project was developed to manage very high industrial power demand, reduce grid electricity costs, and minimise diesel generator dependency, while ensuring advanced safety, grid compliance, and long-term operational reliability.
This installation stands as a reference large-capacity rooftop solar project for the plastics and packaging manufacturing industry in West Bengal.
