Plastic products manufacturer Kay Plast Product has installed a 1 MW rooftop solar system at its facility in Kanpur, Uttar Pradesh, helping the company reduce high electricity costs and secure reliable, sustainable power.

Executed by Grun Power, the project uses Waaree 590 W N-Type Topcon modules, Sungrow inverters, and an aluminum mounting structure for long-term durability and performance.

Before switching to solar, Kay Plast’s energy consumption averaged 15,000 to 16,000 units per day or around 480,000 kWh monthly.

The rooftop system is expected to cover approximately 25% of the company’s monthly electricity costs, with a payback period of three and a half years, after which the savings will continue throughout the project’s life.

Kay Plast’s product range includes plastic containers, packaging materials, household items, and customized plastic components.

Installation posed challenges, including space optimization, logistics, and compliance with local policies. Grun Power worked with the local distribution companies and the Electrical Safety Department to secure timely net metering and approvals. A unique solution involved using raceways for table-to-table DC cable laying instead of flexible pipes or PVC conduits, which helped avoid monkeys from attacking the cables and ensured long-term reliability.

“The micro, small, and medium enterprises sector is the backbone of India’s economy, and high energy costs remain a challenge. At Grun Power, we are addressing this with customized rooftop solar solutions,” said Ashish Tak, Co-Founder at Grun Power.

Commercial and industrial (C&I) entities, large institutions, and residential apartment buildings are all seeking clean energy solutions at a lower cost than traditional grid power tariffs. Rooftop solar, being the most cost-effective and environmentally friendly energy source, presents an attractive option for C&I businesses aiming to reduce their operating expenses.

Mercom India hosts a multicity ‘C&I Clean Energy Meet’ series designed to provide C&I energy buyers with the knowledge and tools they need to adopt clean energy solutions and lower their power costs. The next Clean Energy Meet event will be held in Jaipur on September 19, 2025.
