Plastic components manufacturer Pune Polymers has installed two rooftop solar systems totaling 705 kW across its manufacturing facilities in Maharashtra, aiming to reduce grid dependency, lower peak demand charges, improve cost predictability, and enhance reliability.

The installations are expected to generate over 910,000 units of electricity annually, helping reduce power bills by approximately 30–40%. The move is projected to deliver annual savings of ₹7.3 million (~$78,603) to ₹9.1 million (~$97,984).

The project, executed by B. U. Bhandari Energy, comprises 400 kW at the company’s Chakan facility and 305 kW at its Waluj plant. The system has been deployed under a capital expenditure model and is integrated with net metering, enabling the company to optimize solar energy consumption while exporting excess power to the grid.

Plant-wise, the Chakan system is expected to generate approximately 531,182 kWh annually at a specific yield of 3.6, while the Waluj system is expected to generate approximately 385,210 kWh at a specific yield of 3.4.

Pune Polymers, established in 1991, manufactures plastic molded components and has diversified beyond its initial association with Bajaj Auto into sectors such as automotive, defense, electrical, telecommunications, healthcare, and pharmaceuticals. The company operates six manufacturing units with energy-intensive processes that require continuous and reliable power.

The solar installation is expected to significantly reduce the company’s reliance on grid electricity, particularly during high-tariff periods under time-of-day pricing mechanisms. In addition to cost savings, the project is estimated to offset around 751 tons of carbon dioxide emissions annually.

B.U. Bhandari Energy customized the system based on the company’s load profile to ensure optimal performance. The installations use Waaree Energies modules and Growatt inverters and are equipped with real-time monitoring to track generation and system performance.

The project was completed within the planned timeline without disrupting ongoing operations at either facility.

B.U. Bhandari Energy had earlier installed a 1.055 MW rooftop solar system for Fleetguard Filters. It also commissioned a 620 kW solar installation for Zensar Technologies in Pune.

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 options for adopting renewable energy. The next event will be held in Mumbai on April 16, 2026.
