The Brief
Three village clusters in a hill district shared one winding road to the district market town. After dark the road was effectively closed — buses stopped running, and two fatal accidents in as many years pushed the district office to act.
Constraints that shaped the design:
- 14 km of road with no grid infrastructure along most of its length
- Steep switchbacks requiring an articulated-lift installation crew
- Monsoon reliability: lights must ride out week-long overcast stretches
- Maintenance reach: the nearest technician is a full day’s drive away
Our Solution
The TR408-A all-in-one was chosen for exactly this profile — one SKU, one unit per pole, nothing to wire together on site.
- 180 units at 30–35 m spacing through the populated stretches
- Battery bank sized for 5 days of overcast autonomy
- Helicopter-free logistics: all units packed on pallets deliverable by 4WD truck
- Local electricians trained on-site during installation; spare-parts kit left with the district office
Numbers
- 180 units / 14 km commissioned in 5 weeks
- 100% uptime through the first monsoon season
- Bus service extended by 2 evening departures
- Reported night-time incidents on the road: zero since commissioning
