Supporting transition to renewable energies

KEYLIOS® Solar Tracker

Nexans Solar Tracker: a unique design for unique customer benefits

A revolutionary single axis tracker technology

  • A solar tracker is a rotating structure that optimizes the orientation of solar panels along the day to maximize energy output.
  • Solar Trackers allow 15% to 30% additional yield compared with fix-mounted solar structures
  • NST designed a robust and modular product that can be installed in areas not suitable for traditional trackers


Lightweight and robust lattice structure

  • Highly resilient design, insensitive to destructive aerodynamic phenomena
  • Capacity to operate under a wide range of conditions, even in strong winds
Easy to install

Two foundations only

  • Pre-assembled structure
  • Optimized onsite logistics Lower assembly cost



Modular Design

  • Optimized onsite logistics with industrialized assembly workshop
  • Pre-assembled structure
  • Lower assembly cost
  • High-speed assembly

Your challenge as Solar Developper

In some countries and regions, availability of terrains for solar development is becoming more critical. Developing competitive solar farms on terrains that are not suitable to trackers can be challenging: installation costs can be high due to various criteria such steep slopes; drilled foundations  can be expensive or even forbidden. Typical examples are former landfills, industrial wastelands, old quarries etc. but also hilly terrains or unstable grounds.

Our solution

  • Nexans Keylios 2V trackers come with a disruptive design that allows them to carry up to 40 modules per foundation.
  • They require 3 to 7 times less foundations that traditional trackers for a given ouput, depending whether you compare to 1V or 2V trackers, and whether you use drilled piles or concrete foundations.

Key benefits

  • Compatible with all foundation types, drilled or superficial
  • Up to 75% saving on installation cost
  • Possibility to develop competitively terrains that were previously unsuitable to solar trackers
