Sunlight, engineered for rail.
A curved, aerodynamic solar panel formed to the exact profile of a coach roof — so every train can generate its own clean electricity, at speed, in any weather.
Brushed 6000-series shell
2.60 × 1.79 m footprint
A moving fleet
is a moving grid.
India runs one of the largest rail networks on earth. Every coach carries square metres of unused roof through hours of direct sun.
VANDHE turns that surface into onboard generation — trimming diesel, easing the grid, and powering lighting, fans and HVAC straight from daylight.
Curved to fit.
Built to belong.
Most solar is flat — bolted onto racks that catch the slipstream. VANDHE is roll-formed to the camber of the roof, so it sits flush with the coach line.
Aerodynamic. Low-profile. Invisible from the platform.
Roll-formed to the coach camber
Five parts,
one surface.
Every layer is engineered to survive the mainline — from the laminated cells to the seam that clamps it down.

Made for 160 km/h
and all the sky throws.
An aerospace-grade brushed shell, vibration-qualified for rail, sealed to IP68 and finished with an anti-glare, low-soiling coat.
Validated from desert heat to monsoon downpour.

Figures indicative — replace with certified test data.
One panel.
Every coach.
Retrofit an existing rake or factory-fit a new build — the seam system clamps on without piercing the roof.
Clean power,
compounded.
Multiplied across a fleet, rooftop generation adds up fast.
