Fleetguard Filters, a provider of filtration solutions for automotive, industrial, and engine applications, has commissioned a 1.055 MW rooftop solar system at its plant in Pune, Maharashtra.

Executed under an operational expenditure (OPEX) model by B. U. Bhandari Energy, the project is designed to curb grid power purchases and shrink the company’s carbon footprint without incurring upfront capital expenditure.

The company’s pre-solar consumption averaged approximately 450,000 kWh per month. With the new system online, Fleetguard Filters expects electricity bills to decrease by approximately 40–50%, resulting in immediate savings compared to prevailing grid tariffs.

The system uses high-efficiency TOPCon modules from Goldi paired with Solis K5G Pro 110 string inverters. The string architecture supports granular MPPT control across multiple roof blocks and orientations, helping stabilize output under partial shading and typical brownfield constraints. Standard protection, earthing, and remote monitoring enable performance tracking and alerts.

Safety and logistics were central to execution on an active industrial site. Work-at-height protocols, mandatory PPE, certified fall-arrest systems, and clearly demarcated zones were enforced, supported by daily toolbox talks. Lift planning and material movement were coordinated to avoid production interference and maintain safe access throughout the build.

B.U. Bhandari Energy reported zero incidents, emphasizing clean cable management and high-quality workmanship.

Under the OPEX arrangement, the developer is responsible for operations and maintenance, including routine cleaning, preventive checks, and remote diagnostics to minimize downtime. The component selection and string-level visibility are intended to support reliable generation over the system’s service life, though performance ratio targets and carbon-avoidance estimates were not provided.

Fleetguard has also entrusted B.U. Bhandari Energy with the installation of a 1 MW rooftop solar project at its Jamshedpur plant.

B.U. Bhandari Energy has earlier commissioned a new solar installation totaling 620 kW for Zensar Technologies in Pune. This project consisted of a 350 kW rooftop system and a 270 kW solar carport, collectively generating approximately 900,000 kWh of clean energy annually, which offset a significant portion of the company’s power needs.

Mercom India hosts a multicity ‘C&I Clean Energy Meet’ series designed to provide commercial and industrial energy buyers with the knowledge and tools they need to adopt clean energy solutions and lower their power costs. The next C&I Clean Energy Meet will be held in Bhubaneswar on November 14, 2025.
