Self-locking tracker for bifacial modules to be presented at Intersolar

Higher yields with smart assembly solutions – this is at the forefront of the Schletter Group’s presence at Intersolar Europe 2019 this week.

The reverse side of the tracking systems was modified so that the modules can be installed without shading.

Among other innovations, the Schletter Group, the globally active producers of solar mounting solutions present their tracking system, which has been optimised for bifacial solar modules. “Yield optimisation for PV systems is the hot topic in the industry at the moment. This is underlined by massive demand for bifacial modules,” Cedrik Zapfe, Co-Managing Director and Chief Developer of the Schletter Group emphasises. “With our new and further developed mounting solutions, we are making a crucial contribution to leverage previously unused yield potential.” By way of examples, Cedrik Zapfe then cites the integration of bifacial modules, material savings based on new high-performance materials, faster planning and assembly due to smart design solutions and, last but not least, easy handling of system components on the part of resellers.

Tracking system for bifacial modules

The Schletter Group presents its 2018 tracking system, which has been sold in Europe, Africa and Australia in a new version that is optimised for bifacial modules. For this purpose, the reverse side of the module tables was modified so that the modules can be installed without shading, i.e. without any disturbing metal struts or the like. Unlike most single-axis tracking systems, the Schletter Tracker does not require a central torque tube at the pivot point of the table. This allows for greater flexibility when it comes to module arrangement and the use of bifacial modules in particular.

“This does not change the key design advantage of the Schletter Tracker,” Christian Salzeder, CSO Tracker at Schletter adds. The system works with a patented physical self-locking mechanism, i.e. there is a mechanically locking element on each post, which locks automatically if the row is not moved. This eliminates all wind-induced vibrations (so-called galloping effect) for the entire row. When in the resting position, the system therefore has the characteristics and resilience of a fixed installation, suitable for wind speeds of up to 260 km/h.

The upper assembly group with the drive unit is delivered pre-assembled. This means that the system can be installed almost as quickly as a fixed installation. The Schletter Tracker is already being used with bifacial modules at a project in Bavaria. (mfo)
