950kW Solar Project For Central Cable Ltd., Nagpur
Client Name: Central Cable Ltd.
Location: Hingna, Nagpur, Maharashtra
Total Project Capacity: 950 kW Rooftop Solar System (Installed in 2 Phases)
The Story, How This Project Was Won
Every great project begins with trust. Chirayu Power's journey to Central Cable Ltd. begins not in Hingna, but at Simplex Chemopack — where Chirayu Power's work spoke louder than any sales pitch.
Chirayu Power completed Simplex Chemopack's solar installation in two phases — 1 MW in Phase 1 and 1.9 MW in Phase 2 — delivering on every promise, from energy savings to engineering excellence. Simplex Chemopack was delighted with the quality, precision, and after-sales support that Chirayu Power is known for. And in Nagpur's industrial belt, satisfied clients talk.
"Results don't just generate energy — they generate confidence. And confidence is the most powerful referral letter in the world."
That confidence brought Central Cable Ltd. directly to Chirayu Power — a leading manufacturer of PP bags and industrial packaging solutions in Hingna, Nagpur. They entrusted Chirayu Power with the design and complete installation of a 950 kW grid-tied rooftop solar system, executed in two phases to suit their operational and financial planning — making it one of Chirayu Power's most significant industrial solar installations to date.

Key Challenges Faced During Installation
One of the primary engineering challenges in this project was executing a phased installation plan across different years while ensuring full system compatibility and seamless integration in Phase 2 with the existing Phase 1 infrastructure.
The Chirayu Power engineering team carefully designed the Phase 2 system to complement the existing 500 kW installation — ensuring both systems operate independently and optimally without grid compliance issues.
Export limiter configuration was a critical aspect, ensuring that combined generation from both phases does not exceed MSEDCL grid export limits at any point of time.
Project Outcome
The successful phased installation of this 950 kW rooftop solar system has helped Central Cable Ltd. take a significant step toward energy independence, operational sustainability, and long-term cost savings.
With world-class components from Jinko Solar, SolarEdge, Sungrow, and Triana — combined with Chirayu Power's in-house structural engineering and precision installation — the system is built to deliver reliable, high-efficiency generation for 25+ years.
The installation covers the complete rooftop with optimised panel layouts, safe walkway access, full protection infrastructure, and a real-time monitoring system that keeps the client informed of live generation performance.
Conclusion
The commissioning of the 950 kW rooftop solar power plant at Central Cable Ltd., Hingna, Nagpur — executed in two phases in 2022 and 2025 — demonstrates how a strategically planned, phased solar investment can progressively transform electricity costs into long-term savings.
Chirayu Power Pvt. Ltd. remains committed to delivering high-quality, engineering-first solar installations that help industries achieve sustainability, energy efficiency, and financial stability — one project at a time.
Central Cable Ltd. trusted Chirayu Power — and so can you. Whether you're planning a 100 kW or a 1 MW installation, Chirayu Power brings the same engineering excellence, world-class components, and after-sales commitment to every project.
