Rooftops can be a good choice for installing solar systems in the commercial and industrial sector, thanks to their large rooftop spaces and fewer shaded areas.

One such example is Oswal Soap Group, a soap manufacturer, which has saved ₹5 million (~$56,484.5) annually by installing a 162 kW rooftop solar system at its Jaipur factory in Rajasthan.

The Oswal Soup Group specializes in the manufacture of detergents, bath soap, and other daily-use items, including tea, spices, and sanitary products.

With high power needs, the soap manufacturer incurs an annual power expenditure of ₹7.5 million (~$84,726.8). To reduce its power costs, the company invested ₹4.5 million (~$50,836) to install a rooftop solar system on its premises.

The rooftop system generates approximately 648 kWh per day and 19,440 kWh per month.

Rajasthan-based rooftop installer TechSun Solar Power commissioned the project in October 2025. The installation was completed in a month.

The system was set up using Vikram Solar’s 600 Wp bifacial TOPCon modules, coupled with two 50 kW inverters and another 60 kW inverter from Solis India.

The rooftop system is set up as a behind-the-meter project.

The rooftop system includes a flash mount to prevent water leakage, a fiberglass-reinforced plastic walkway to avoid module breakages, and a water facility for cleaning the modules.

With this installation, Oswal saves nearly 70-80% on its monthly power costs.

The company has also installed a 60 kW rooftop system at its other factory that manufactures Indian masalas.

Companies in the C&I sector are increasingly turning to rooftop solar to reduce power costs and make their operations more sustainable. 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 at Nagpur on December 12, 2025.
