220kW Solar Installation at MR Enterprises by SolarLogix
SolarLogix successfully designed and executed a 220 kW industrial rooftop solar power plant for MR Enterprise, a cold storage facility under the food processing sector, located at Bijayrampur near Ramchandrapur, Sutahata, Haldia, West Bengal.
The project was developed to address high continuous power demand, reduce electricity and diesel generator costs, and ensure stable, uninterrupted energy supply for temperature-sensitive cold storage operations, while maintaining advanced safety and grid compliance.
This installation stands as a reference rooftop solar project for cold storage and food processing units in West Bengal.
