The most powerful yield enhancement available in solar mounting technology. The Vlux Single-Axis Tracker follows the sun from east to west on a north–south axis — capturing 20–25% more energy than an equivalent fixed tilt system. Designed for utility-scale projects where yield premium drives return on investment.
A single-axis tracker rotates solar panels on a horizontal north–south axis throughout the day, continuously optimising the angle between the panel surface and the sun's position. The result is dramatically higher energy capture — particularly during morning and afternoon hours when fixed panels are less efficient.
Vlux Single-Axis Trackers are engineered for Indian utility-scale conditions — including high wind zones, laterite and black cotton soil foundations, and dense panel rows. Our tracker design uses a torque tube backbone with driven pile foundations and motor-controlled rotation via a central controller, with +99% tracking uptime by design.
Single-axis trackers deliver the highest ROI when the cost premium over fixed tilt is justified by the yield increase. This is typically the case for projects above 1 MW in flat terrain locations where land cost is low and the cost per kWh generated is the primary financial metric.

Every feature listed here is a deliberate engineering decision — not a marketing bullet point. Here is why each one matters for your project.
The tracker rotates continuously from an east-facing position at sunrise to a west-facing position at sunset — maintaining the optimal panel angle throughout the day and capturing morning and afternoon energy that fixed tilt installations miss entirely.
In Indian conditions with 5.5–6.5 peak sun hours, a single-axis tracker adds 20–25% more energy per installed kW compared to the same panels on a fixed tilt structure. On a 10 MW project, that's 2–2.5 MW of additional capacity — for free.
Vlux trackers use a multi-unit controller system with real-time tracking, remote diagnosis, and intelligent fault detection. The system automatically stows panels in a flat position when wind speeds exceed a set threshold — protecting the structure during storms.
The torque tube is the structural spine of our tracking system — a continuous HDG steel tube running the length of each row, transferring the rotational force from the motor to every panel in the row simultaneously with minimal mechanical complexity.
Standard single-axis tracker foundations use driven steel piles — no concrete, no curing time, no waiting. Pile driving is 3–5x faster than concrete footings and allows immediate structure erection after soil testing confirmation.
Our tracker controller includes backtracking algorithms that adjust each row's angle during low-sun-angle periods to eliminate inter-row shading — maximising energy capture across the entire array even on large, dense installations.
Every Vlux project follows a structured 4-stage process that eliminates surprises — from the first site visit to final commissioning sign-off.
