Solar power adoption in India’s commercial and industrial (C&I) sector is accelerating as companies seek to manage rising electricity costs, meet sustainability targets, and ensure long-term energy security.

One such company is Honeywell Industrial Automation, which has installed a 332.30 kW rooftop solar system at its facility in Dehradun. While the first post-solar electricity bill has not yet been generated, the company expects annual savings of ₹3.33 million (~$37,548).

Honeywell provides advanced solutions that help process industries operate more efficiently and safely. The company develops world-class sensor technologies, automation and control systems, and digital solutions that streamline industrial operations.

Honeywell’s total energy requirement at the facility is approximately 780 kW per day. Due to contractual demand limitations, the rooftop solar system capacity was capped at 332.30 kW, demonstrating the role of on-site solar in significantly offsetting grid power consumption for industrial units. The system includes Navitas 590 Wp TOPCon solar modules for this project, paired with two Sungrow 125 kW inverters.

Despite this restriction, the installation is expected to supply around 42.6% of the facility’s total energy needs. Honeywell’s annual energy charges are estimated at around ₹8 million (~$90,233) based on existing consumption patterns.

Maharashtra-based renewable energy solutions provider, Artha Energy Resources, in partnership with Blink-Infra Projects, commissioned the project on November 27, 2025.

Animesh Damani, the Founder and Managing Partner of Artha Energy, said, “The project faced site-specific challenges due to the hilly terrain, including the requirement for manual earthing and heightened safety considerations. We deployed additional skilled manpower and worked closely with a safety-conscious client team to ensure compliance, safety, and timely execution.”

The company stated that its prior experience with rooftop solar projects across diverse geographies helped it address these challenges without delay. The initial coordination issues arose from multiple stakeholders involved in the rented infrastructure, but they were resolved during commissioning.

Artha Energy will provide maintenance and asset management services for 25 years, ensuring the system’s long-term performance and reliability.

The company noted a broader surge in solar adoption across the C&I sector, driven by sustainability commitments, cost pressures, and supportive government policies.

To raise awareness among businesses about the benefits of transitioning to solar, Mercom India has been hosting nationwide ‘C&I Clean Energy Meets’ that bring solar developers and companies intending to adopt clean energy sources under one roof.

The next event will be held in Nashik on January 9, 2026.
