Snow sensor

The snow sensor serves the purpose of detecting snow and ice on the modules. It is mounted at the bottom edge of the module surface.
If both the module surface and the snow sensor are covered with snow and the sensor measures a snow or ice layer, which could be critical for the statics when exceeded, the DEGER will be moved to the maximum vertical position. Snow and ice can now slide down. Once the snow sensor is free again, the DEGER will return to MLD-operation.

The snow sensor can be used with all DEGER and due to the surface it is obligatory for DEGER D80 and D100.


  • Snow free module surface in the winter, i.e. PV-yield after snowfall without any efforts (clearing the module surface).
  • Low static snow load

Scope of delivery:

The snow sensor consists of a sensor installed in a stable sheet metal housing, with 5 m cable, mounting brackets and fastening material.

CCB III with windguard advanced, heatable for heavy duty

The CCB III (Central Control Box) provides the possibility to control the DEGER manually via joystick, and to connect the safety sensors (wind sensor, snow sensor and insolation sensor).

Each individual system or each solar park requires one CCB for up to 100 DEGER. When operating the joystick, all connected systems will move. In order to avoid damage caused by high wind loads, the integrated and heated wind monitor unit "Advanced" will move the DEGER to the safety position, when the wind speed reaches 12 m/s. The anemometer is insensitive against wind gusts and will only trigger wind alarm in case of permanently applied strong wind.


  • manual control (e.g. to be able to mow the lawn under the trackers)
  • one CCB for 100 systems
  • protection against too high wind loads
  • robust heated anemometer
  • insensitive against gusts

Scope of delivery:

The CCB III consists of a central control and the wind monitor unit incl. anemometer Standard or Advanced with 20 m cable, mounting bracket and assembly accessories.

Pendulum for windguard

All DEGER require a wind monitor to protect against storm damage. It moves the module surface of the systems to horizontal position, when a preset wind speed is reached. The wind monitor is typically mounted on a mast, so that it can sense the actual wind speed at the appropriate height.

The pendulum holder gives you the possibility to fasten the wind monitor directly to the module surface of the tracking system. Due to the pivot mounted pendulum with a counterweight fastened on the nodal bar, the nodal bar will always rotate to vertical position at any position of the DEGER. This makes sure that the anemometer of the wind monitor is always optimally exposed to the wind and will never be in the slipstream of the DEGER.

Alignment tool for tracking systems

The alignment tool is an aid to align the DEGER under an exactly 90° angle to the sun. The photovoltaic module reaches its highest yield when it is aligned under an exact right angle to the light source.

The patented Maximum Light Detection sensor technology has been developed for a permanent realignment of the DEGER to the brightest spot in the sky. By eliminating any possible alignment faults of the MLD sensors, the system works even more efficiently and produces a higher yield.


Higher yield by correction of possible alignment faults.


The DEGER Mini is particularly suitable for use at exhibitions and has been developed for quick, simple and understandable demonstration of the function of a DEGER. Just like the real dual-axis tracking systems, the MLD sensor recognizes the location of maximum illumination and turns the module surface through both axes to make sure that the illumination is vertical to the module surface. A torch is typically used as light source for the DEGER Mini. The model is operated with 230 V/AC mains voltage.
The packaging has been designed for re-use, thereby ensuring safe transportation to trade shows and exhibitions.
