Case Study
850 kWp Rooftop Plant for a Textile Unit
A metal-sheet rooftop plant offsetting a large share of the factory's daytime load.
Project capacity
850 kWp
Location
Howrah, West Bengal
System type
On-Grid · Metal-sheet rooftop
Commissioned
November 2025
Energy generation
11,90,000 kWh / yr
Customer savings
₹95.00 L / yr
Client: Textile manufacturer (SAMPLE)
The challenge
The client's ageing metal-sheet roof and three-shift operation required a lightweight structure that wouldn't void the roof warranty and a phased install that wouldn't stop production.
Our solution
We designed a rail-less, seam-clamped structure with no roof penetrations, split the plant into four blocks for phased commissioning and integrated it with the existing HT panel and DG synchronisation.
Results
- Commissioned in 9 weeks with zero production downtime
- Payback estimated under 4 years
- ≈ 860 tonnes of CO₂ avoided every year
