1. The challenge
A withering-and-drying factory 14 km from the nearest reliable feeder, running on two diesel gensets.
Operating since February 2025
Off-grid · Industrial
220 kWp off-grid system for a tea estate factory
41,000 L diesel avoided per year — Tea estate & processing unit, Sylhet.
- Capacity
- 220 kWp + 600 kWh

2. Our approach
220 kWp ground and rooftop mix, 600 kWh LFP bank, genset kept as last-resort backup under automatic control.
3. The result
Gensets now run under 300 hours a year. Diesel purchases fell by roughly 41,000 litres annually.
