49kW Solar Installation at Joy Products by SolarLogix
SolarLogix successfully designed and executed a 49 kW industrial rooftop solar power plant for Joy Products, a manufacturing unit in the toys industry, located in Purba Bardhaman district, West Bengal.
The project was implemented to reduce high daytime manufacturing electricity consumption, control rising power costs, and support the company’s move towards clean and sustainable energy, while ensuring safe grid-compliant operation and long-term system reliability.
This installation serves as a reference rooftop solar project for small-to-mid scale manufacturing units in West Bengal.
