201 kW rooftop solar across five locations for a top ranking car dealership in Kerala
At a glance
Established in 1984, the top-ranking car dealership has built a strong reputation and presence across Kerala. To reduce electricity costs, the organisation partnered with DE under a Power Purchase Agreement (PPA).
After successfully completing three rooftops in Phase 1, the customer explored adding more systems independently but faced execution challenges and lower-than-expected savings. They subsequently re-engaged DE for Phase 2, adding five additional rooftops to the portfolio. This model enabled the dealership to adopt clean energy with no upfront investment, while DE continues to manage performance, operations, and maintenance across all live sites.
Performance
Challenges and solutions
1. Voltage instability challenge
Unstable voltage levels from the Kerala State Electricity Board (KSEB) caused repeated inverter tripping, affecting plant uptime and generation.
DE installed a high-capacity voltage stabilizer, ensuring steady input voltage, protecting all inverters, and enabling uninterrupted generation.
2. Difficulty realising savings independently
After Phase 1 (three rooftops), the customer tried adding more systems independently but faced execution challenges and lower savings.
DE was re-engaged for Phase 2, using its engineering expertise and performance monitoring to deliver five additional rooftops with reliable performance and clear savings.
Impact and benefits
28% annual cost savings on electricity bills.
2,43,007 kWh clean energy generated so far; 176 tonnes CO₂ offset, equal to 123 tonnes of coal saved or 38 cars taken off the road.
DE provides full performance monitoring, preventive maintenance, and real-time reporting.
“Working with Distributed Energy has been a really smooth experience for us. Their team handled the installations across our sites without any hassle, and we're already seeing the drop in our electricity costs. It feels good to know we're doing our bit for the environment too.”
Senior Manager, Operations, Car Dealership (Kerala)This 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.
