Schletter presents a solar tracker with a locking mechanism without solar damper

With a width of four metres, this single-axis tracking system not only allows a ground cover ratio that few other systems can match thanks to its patent pending locking mechanism. It also has the same level of stability as a fixed mounting system, promises Schletter.

According to the company this tracker slewing drive combines the benefits of Schletter’s fixed mounting systems with the additional yields of a tracking system. Easy assembly and servicing were also key aspects when designing the system. An innovative drive concept is at the heart of this new tracker. It requires no hydraulic solar dampers and completely avoids the dangerous ‘galloping effect’ under wind loads.

While most other tracking systems use hydraulic solar dampers or similar supporting structures to mitigate the vibrations and torsional forces caused by the wind, this Schletter system works with a self-locking mechanism. Each post is equipped with a mechanical locking element which automatically locks as soon as has stopped slewing drive moving
