DEGERconecter Control System for the DEGERtraker

Accurate adjustment ...The DEGERconecter always adjusts the solar installation to face the brightest point in the sky. It includes theentire system control. ... Maximum power yieldDuring times of sunshine the module surface is accurately adjusted to face the sun. During times of overcastweather, the DEGERconecter automatically adjusts to face the point with the strongest global radiation. A control system to rely on. The patent-protected DEGERconecter control was awarded the inventor’s prize of the federal state ofBaden-Württemberg in 2000.Description of DEGERconecter functionsTwo sensor cells in the DEGERconecter supply reference values which are evaluated by the logic device, andwhich provide the basis for the adjustments of the module surface in the course of the day. A third sensor cell isattached to the back of the DEGERconecter to reset the installation in the morning. Depending on the irra-diation intensity, a differential amplifier controls the transition from the logarithmic characteristic curve duringstrong irradiation to a linear characteristic curve during low currents in diffuse light. That means that the logicdevice accepts a much higher value for the linear characteristic curve than for the logarithmic characteristiccurve. This leads to improved adjustment accuracy in dimming light. A load is added to the differential voltage,moving the switch-off threshold further into dusk, to ca. 30 W/m2.

Drive controlThe drive is controlled directly - and without requiring additional parts – by the MOSFET bridge circuit, which isintegrated in the DEGERconecter. The bridge is characterised by a very low closing resistance. To avoidoverload of the motor and the DEGERtraker’s structure, a current limiter was integrated into the system.This current limiter functions dynamically, i.e. the motor is switched off as a response to overload (e.g. frozen orblocked drives). As soon as the drive works again, the system is reset automatically.

Benefits- No computer with high energy consumption required- no rotation angle potentiometer, relay, step motors ... required- no networking with data lines required- the automatic drive does not contain any electromechanical parts- little cabling required for large solar parks- simple, easy-to-use control technology- efficient utilisation even during cloudy weather- only makes movements which directly lead to increased power yield.

Tasks of an energy converterThe energy converter exploits wide voltage ranges of solar modules, battery systems and the grid for the DEGERconecter.The power for the control and drive systems may also be supplied without a battery, by direct connection to solar modules withbelow one Watt power.

During dawn, the DEGERconecter recognises the brightest spot in the sky and tries to reset the installation. The power sup-ply module for the control system starts by producing 0.01 Watts or less, and as soon as the DEGERconecter attempts tocontrol the electric motor, the voltage on the solar module breaks down. To avoid the DEGERconecter switching the driveon and off all the time and to achieve quick resetting, DEGERenergie has developed the energy converter. The energy con-verter collects even small power inputs from the solar module (which are too small to be fed into the grid) in a high perfor-mance condenser and makes this energy available to the DEGERconecter. The DEGERconecter is thus able to resetthe installation to face the brightest spot even before the modules produce enough energy to be fed into the grid. To avoid bothdrives from working simultaneously, the energy converter gives the east-west drive priority over elevation. The energy conver-ter also ensures that no more than ca. 1-3 Watts is taken from the solar module while the drive is running. The control does notuse any energy during the night.

Power supply- directly from the solar module or string,- from a battery for stand-alone-sytems,- from the AC grid,- or from an additional 1-5 Wp solar module for self-sufficient systems.


DEGERconecter: the new control system forthe DEGERtraker.

During times of sunshine, the module surface is accurately pointed at the sun. During times of overcast weather, theDEGERconecter adjusts the module to face thepoint with the strongest global radiation.

A high-yield solar electric power station ...With this system it becomes a reality. If you use of TOPtraker tracking systems, you have acknowledged the

signs of our times: Apart from thinking and acting in accordance with environmental protection and nature, you

also profit from increased yields and the associated amortization.

Maintenance-free. Long-lived. Recyclable.The systems designed to these exacting parameters are mass-produced in an ISO 9001-certified factory under

environmentally sound conditions. Altogether, the TOPtraker systems are 100% recyclable as true valuable

substances. In comparison to rigid systems, after conclusion of the useful life 25% less electrical scrap will occur!

The proven static design of the TOPtraker is based on DIN 1055-4 (3/05).

Short assembly time.Pre-mounted components and the low net weight permit an assembly time of less than 30 minutes.

Scope of deliveryComplete tracking system in optimised azimuth axis,DEGERconecter control electronics, aluminium solarmodule carrier system, to fit the respective moduletype, construction plan.

On principle simple.

The operating principleThe control unit DEGERconecter detects the brightest spot in the sky and rotates the module area into this direction. The DEGER TOPtraker has the mechanics of a single-axis tracking unit built in. During the daily and yearly course, lossangles result between module area and the sun. These cannot be completely counterbalanced with any mechanical method.However, by the available degree of freedom of the mechanics and the momentary position of the sun the DEGERconectercan calculate the smallest loss angle and then adjust the module area with the smallest possible deviation. This technologyworks also with cloudy sky, rain and fog; i.e. if on a day that at first begun sunny, in the afternoon clouds draw up from thewest, the module area will rotate slightly back toward the east according to the irradiation. With a totally cloud-covered sky,the module area is rotated into the direction of the strongest irradiation in order to make the best also from bad weathersituations.

BenefitsAs a result of the simple construction, the low weight, as well as pre-assembled components, the assembling time per systemwill usually be less than 30 minutes. Thus with almost identical costs an enormous yield increase is achieved with the TOPtraker.
