Established in 1992, this Pune-based precision engineering manufacturer produces high-accuracy components for sectors such as automotive, railways, power, and hydraulics. With a strong reputation for quality and reliability, the company has maintained a commitment to operational excellence and sustainability.
To reduce its energy expenditure and transition toward cleaner power, it partnered with DE to commission a 1030 kW rooftop solar plant under a PPA model, enabling cost-effective renewable energy consumption without upfront capital while DE manages the plant's operation and maintenance.
Performance
Challenges and solutions
1. Access-related delays
Site access and the client's internal timeline for extending the main electrical bus bar caused installation delays.
DE created a revised phased schedule and held daily meetings with the client's facilities team to align readiness with crew deployment and reduce downtime.
2. Roof shading from adjacent structures
Shading from neighboring buildings and parapet walls reduced the effective solar window on portions of the roof.
DE conducted a detailed shadow analysis and redesigned the array orientation and mounting heights to ensure maximum generation.
Impact and benefits
54% annual cost savings on electricity bills.
12,13,313 kWh clean energy generated so far; 839 tonnes CO₂ offset, equal to 616 tonnes of coal saved or 190 cars taken off the road.
DE provides full performance monitoring, preventive maintenance, and real-time reporting.
“From material delivery to final commissioning, every step was managed with proper coordination and documentation. The team was approachable, quick to respond, and ensured that the project moved ahead without delays. We truly appreciate their commitment to both quality and timelines.”
Management, Precision Parts Manufacturer, PuneThis project demonstrates how DE empowers institutions to achieve measurable savings while advancing their sustainability goals. By combining flexible financing, reliable operations, and data-driven performance monitoring, DE enables businesses to switch to solar without upfront investment.
