FAQ Technology

The single-axis DEGER 8.5 and S60H tracker also the dual-axis DEGER D60H and 3000HD tracker are ideal for building integration.

There are different foundation possibilities for a DEGER tracker:

Round or square concrete foundation for dual axis tracking systems:

The size of the concrete foundation depends on the system used and the mast length employed. The foundation can be optionally a surface or underground installation. In the case of underground foundation, a longer mast is needed, in order to allow the required ground clearance. A reinforcement plan or optionally a pre-assembled reinforcement cage can be provided for each foundation.

Driven pile foundation for single axis tracking systems:

The driven pile foundation is delivered with the including ramming piles. The driven pile foundation is individually adapted to local ground conditions on the basis of a geological survey.

Concrete foundation for single axis tracking systems:

The foundation can be optionally a surface or underground installation. In the case of underground foundation, a longer pile is needed, in order to allow the required ground clearance. A reinforcement plan or optionally a pre-assembled reinforcement cage can be provided for each foundation.

All DEGER trackers have factory-installed double protection using electrical limit switches for stopping the motors. The single-axis DEGER tracker in addition, have a mechanical end stop. The DEGER NT-series and HD-series have an optional mechanical end stop.

DEGER are statically calculated and dimensioned in accordance with EUROCODES and German norms for a wind pressure of

1. Up to 102 km/h for DEGER 3000NT, 5000NT and D100 tracker
2. Up to 110km/h for DEGER S100-DR tracker
3. Up to 120km/h for DEGER S100-SR tracker
4. Up to 130 km/h for DEGER 8.5 and D80 tracker
5. Up to 140km/h for DEGER S100-SR tracker
6. Up to 160km for DEGER S100-SR tracker
7. Up to 170 km/h for DEGER D60H and 3000HD tracker

The tracking systems are designed in accordance with DIN 1055-4 (3/2005). With higher wind load stressing, the systems can be adapted by reducing the module surface.

As with fixed systems, the spacing must be such as to prevent the units from shading themselves as far as possible. The spacing is determined substantially by the latitude, because here the degree of possible shading differs in intensity. You can obtain related planning documentation on request.

DEGER can support you with module layout plans and will also provide you with detailed information on your module type/your configuration when you place your order.

DEGER can provide you with an overview for an exemplary number of current solar modules. You can do calculations using a 10% tolerance to obtain a preliminary calculation. Please note that the maximum number of modules can be limited by regional wind load stressing. DEGER offers a planning tool for detailed calculations.

We recommend implementing a sufficient protection against overvoltage and lightning. Each solar park and each system has a unique configuration. The protection against lightning does require a verification of the local conditions and a site specific implementation of the protection system. A suitable solution can be provided by local specialists which also take into consideration the local requirements and specifications.

No wind monitor is required for the DEGER 8.5 tracker because its structure has been designed so that it is storm-safe in any position. (e.g. up to a maximum 45° in the East-West direction). In stormy weather it is normally cloudy and this would bring the DEGER 8.5 tracker in the safest middle position anyway.

The wind guard is pre-wired to the CCB with a 20 m cable. This cable can be extended up to 200m with a suitable cable in case it is not long enough.

The wind monitor positions the module surface in the safe horizontal position when the wind speed exceeds 12 m/sec. This ensures that the safe position is assumed in time before a storm occurs.

The CCB as well as the EC5 and EC6 are weatherproof (IP55). Normally, the EC5 and EC6 are installed directly to the rotating head. The CCB is also suitable for outdoor but should not be accessible to unauthorized people in order to prevent the joystick from moving the DEGER tracker manually.

In virtue of the flexible adjustment of the carrier frame, all current PV modules can be mounted on a DEGER tracker.

The frost depth in the concrete foundation must not be adhered to, i.e. the concrete foundation can be underground or on the surface. For underground foundations, the pole length needs to be determined. The DEGER Steel Foundation must be installed underground.

The precision of the MLD-Sensors is less than1°. l.e. the system will be tracked every 3-4 min. in case of direct sunlight.

No, because the optimal direction for each tracker can vary due to cloudy weather or reflections.
