After the residential sector, industrial installations accounted for the second-highest share of India’s 3.8 GW of rooftop solar capacity additions in the second quarter of 2026, according to Mercom’s Q2 and 1H 2026 India Rooftop Solar Market Report.

The assurance of regular power supply at affordable costs has been pushing the commercial and industrial (C&I) sector towards rooftop solar projects, especially factories which depend on continuous power for efficient production.

A plywood factory in Kanpur, Uttar Pradesh turned to rooftop solar to meet its need for continuous power supply while reducing its grid dependence.

Executed by Grun Power, the project involved installing an 897 kW rooftop solar system. The project was commissioned in April 2026.

Waaree 615Wp modules and Luminous inverters were used in the project.

The rooftop solar project is projected to yield around 1.25-1.34 million units of electricity per year. The plywood factory expects to save around ₹10 million (~$104,400) to ₹10.8 million (~$112,752) annually in power costs after installing the rooftop solar project.

On the challenges faced while executing the project, Grun Power said its team had to install the system in an operational factory without disrupting production. The team worked while ensuring safe movement of workforce and materials in a busy industrial environment to execute the project.

In March, Grun Power executed a 659 kW rooftop solar project for Uttar Pradesh-based Kedarnath Multigrains at its Shahajahapur facility. The installation used high-efficiency TOPCon bifacial solar photovoltaic modules to enhance output and long-term performance.

The company also executed a 350 kW rooftop solar project for a manufacturing facility in Kanpur in January 2026. With the installation, the facility cut down its monthly electricity expenses by around 30% to 40%.

On an average, solar energy meets 40% to 45% of the facility’s daily electricity requirement during operational hours, while during peak daytime periods, the contribution rises to 50% to 60%.

Mercom India hosts a multicity Clean Energy Meet series to bring renewable energy developers and vendors and, C&I energy consumers on the same platform helping them share insights on rooftop solar open access and other modes of clean energy procurement. The next event in the series will be held in Lucknow on October 9, 2026.
