India’s textile industry has always been energy-intensive. But with rising power costs and growing pressure to reduce carbon emissions, textile manufacturers are increasingly turning to solar power as a practical business solution.

A recent rooftop solar installation at Dhanish Cotton Mills in Punjai Puliampatti, Erode, Tamil Nadu, shows how clean energy is becoming an important part of industrial competitiveness.

Skyparc Energy India installed and commissioned a 424.96 kW rooftop solar power project for Dhanish Cotton Mills. The project was completed in just 45 days.

The installation uses high-efficiency Credence Bifacial N-Type TOPCon solar modules and Fronius inverters, including three Fronius Tauro 100 kW inverters and one Fronius 50 kW inverter.

The project is expected to generate nearly 1 million units of electricity annually. Based on the estimated generation and prevailing power costs, the annual savings are expected to be around ₹7 million (~$73,250).

For a textile manufacturer, rooftop solar offers a compelling combination of cost savings, sustainability, and energy security.

Skyparc, with a portfolio of around 150 MW of rooftop projects, completed the installation at Dhanish Cotton Mills without major execution challenges.

Industrial consumers often face higher electricity charges during peak periods. In Tamil Nadu, the peak charges are around ₹9.37 (~$0.0981)/kWh. Rooftop solar generation during daylight hours helps offset a portion of expensive grid power, yielding significant savings on electricity expenses.

Dhanish opted for rooftop solar installation after considering regulatory and operational challenges. It also evaluated the ground-mounted solar option, but issues with open access, deviation settlement mechanism regulations, and energy adjustment in Tamil Nadu led them to opt for rooftop solar.

For Dhanish Cotton Mills, rooftop solar offered a more direct and practical solution. The company could use its existing roof space to generate on-site electricity and reduce power costs without relying on more complex power adjustment mechanisms. More and more industrial clusters in Tamil Nadu and across India are adopting rooftop solar, underscoring growing acceptance among commercial and industrial customers to cut power costs and accelerate sustainable development.

Mercom had earlier reported about a New Delhi-based textile mill, RMP Group, opting for a 433-kW rooftop solar installation at its Faridabad facility to reduce power costs. RMP Group expects to cut power costs by 83% with this installation.

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 clean energy adoption. The next event will be held in Hyderabad on August 21, 2026.
