As commercial and industrial (C&I) consumers across India increasingly turn to rooftop solar to manage rising electricity costs and ensure long-term energy reliability, manufacturing companies are emerging as key adopters of on-site renewable energy.

Rooftop solar systems are enabling factories to offset a significant share of their daytime power consumption and improve sustainability performance without disrupting core operations.

Kanpur-based Geeta Polymers has reduced its monthly electricity expenses by around 30% to 40% after commissioning a 350 kW rooftop solar system at its manufacturing facility, marking a significant shift in how the company manages its energy requirements.

Operating under a continuous production load, the company previously incurred electricity bills ranging from ₹700,000 (~$7,770) to ₹800,000 (~$8,880)/month.

Following the installation of the rooftop solar system, the company’s reliance on grid electricity, particularly during daytime operating hours, has significantly reduced, resulting in sustained cost savings.

The company has an average energy requirement of about 400 kW to 450 kW, driven by manufacturing, processing, and auxiliary equipment operations. On average, solar energy meets 40% to 45% of Geeta Polymers’ daily electricity requirement during operational hours, while during peak daytime periods, the contribution rises to 50% to 60%.

This has improved energy planning at the plant and reduced exposure to rising grid tariffs.

Abhimanyu Arora, Director at Geeta Polymers, said, “We decided to install a solar power system to manage rising electricity costs and reduce our dependence on grid power, and the reduction in our monthly bills has been both measurable and consistent.”

Apart from direct financial savings, the company has cited operational and environmental benefits from the solar installation. The system has been operating reliably, supporting smoother plant operations.

Arora also stated that the shift to solar energy has helped Geeta Polymers lower its carbon footprint, align with sustainable business practices, and strengthen compliance with environmental norms.

The rooftop solar project was designed and executed by Grun Power, which engineered the system to maximize energy generation within the available rooftop area. The on-grid solar project uses high-efficiency TOPCON bifacial solar modules.

Ashish Tak, Co-founder at Grun Power, said, “By combining efficient system design with high-performance modules and structured operation and maintenance support, we were able to deliver a rooftop solar plant that meets a large share of Geeta Polymers’ energy demand while delivering clear financial savings.”

The installation was completed, with routine aspects such as rooftop load assessment, layout optimization, and coordination with ongoing manufacturing operations, all managed through detailed planning.

Grun Power is also providing comprehensive post-installation operation and maintenance services.

“Based on the current system’s performance and future production growth, the company is open to expanding its solar capacity to further increase renewable energy usage,” Arora said.

Mercom India hosts a pan-India ‘C&I Clean Energy Meet’ series, bringing renewable energy developers and commercial and industrial power consumers together to discuss options for adopting renewable energy. The next event will be held in Coimbatore on February 5, 2026.
