CONCENTRATOR TECHNOLOGY
DUAL-AXIS
PRECISION IN TRACKING
A MILESTONE IN
CONCENTRATED SOLAR TECHNOLOGY
CONCENTRATOR PHOTOVOLTAICS
(ABBREVIATED TO CPV)
Concentrated solar technologies, such as CPV, need modules to
be very accurately aligned towards sunlight. The mass-produced
DEGERtraker, in conjunction with the new DEGERconecterCT
control, provides an unbeatable price/performance ratio. The
high-precision tracking system is the product of 24 months of
research and development, and has achieved a tracking precision
of 0,03° under laboratory conditions. Nine systems have already
been subjected to long-running tests on the company‘s own test
grounds. Amongst the standard models, the DEGERtraker 3000CT
and 5000CT work with an accuracy of less than 0,1°.
For many years now the solar industry has worked with various
approaches involving concentrated solar radiation. The principle
is simple: In combination with precise tracking, solar radiation is
concentrated on special concentrator solar cells.
Concentrator technology is now facing a crucial breakthrough into
commercial use as well. DEGERenergie has responded to this
development and is now offering 2 tracking systems developed
exclusively for concentrator technology.
CPV, when combined with our CT models, has the greatest potential for reducing production costs and of being successfully used
with the highest levels of efficiency.
The success of CPV technology essentially depends on three
components: high-performance solar cells, optics and tracking.
DEGERenergie has developed a system specifically relating to
tracking that is competitive and based on years of experience in
the solar industry.

Precise tracking is crucial on tracking systems in order to use CPV
technology efficiently. The slightest deviations are immediately
reflected in the efficiency and yield. Structural modifications to
the supporting structures must be taken into account due to the
high weight of the new CPV technologies. The new CT models are
predestined for such high demands.

THE DEGERconecter
THE DEGERconecter
DEGERtraker’s
CONTROL SYSTEM
THE PATENTED
CENTREPIECE
ACCURATE ADJUSTMENT
The DEGERconecter always adjusts the solar installation to face
the brightest point in the sky. It includes the entire system control.
MAXIMUM POWER YIELD
During times of sunshine the module surface is accurately adjusted
to face the sun. During times of overcast weather, the DEGERconecter automatically adjusts to face the point with the strongest
global radiation. A control system to rely on. The patented DEGERconecter control was distinguished with the Innovator Award
of Baden-Wuerttemberg Prize in 2001, has been continuously
improved and has more than 50.000 units in operation.
DESCRIPTION OF DEGERconecter FUNCTIONS
Two sensor cells in the DEGERconecter supply reference values
which are evaluated by the logic device and which provide the basis
for the adjustments of the module surface in the course of the day.
A third sensor cell is attached to the back of the DEGERconecter to
reset the installation in the morning. Depending on the irradiation
intensity, a differential amplifier controls the transition from the
logarithmic characteristic curve during strong irradiation to a linear
characteristic curve during low currents in diffuse light. That
means that the logic device accepts a much higher value for the
linear characteristic curve than for the logarithmic characteristic
curve. This leads to improved adjustment accuracy in dim light.
A load is added to the differential voltage, moving the switch-off
threshold further into dusk, to approx. 30 W/m2.
DRIVE CONTROL
The drive is controlled directly – and without requiring additional
parts – by the MOSFET bridge circuit, which is integrated in the
DEGERconecter The bridge is characterised by a very low closing
resistance. To avoid overload 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 or blocked drives). As
soon as the drive works again, the system resets automatically.
TASKS OF AN ENERGY CONVERTER
The 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 with less
than one Watt power.
During dawn, the DEGERconecter recognises the brightest spot
in the sky and resets the installation. The power supply module
for the control system starts by producing 0,01 Watt or less, and
as soon as the DEGERconecter attempts to control the electric
08
BENEFITS
motor, the voltage on the solar module breaks down. To avoid the
DEGERconecter switching the drive on and off all the time and to
achieve quick resetting, DEGERenergie has developed the energy
converter. The energy converter collects even small power inputs
from the solar module (which are too small to be fed into the grid)
in a high performance condenser and makes this energy available
to the DEGERconecter. The DEGERconecter is thus able to reset
the installation to face the brightest spot even before the modules produce enough energy to be fed into the grid. To avoid both
drives from working simultaneously, the energy converter gives
the east-west drive priority over elevation. The energy converter
also ensures that not more than approx. 1 – 3 Watts is drawn from
the solar module while the drive is running. The control does not
use any energy during the night.
▶ 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
▶ Also bad weather is used efficiently
▶ Contrary to traditional control systems only movements
are performed, that lead directly to a yield increase.
