1 General Information
1.1 MLD technology
DEGER’s patented MLD Control allows for accurate, quick and power-saving operation in orienting the
dual-axis DEGER systems to the position that has the most energy. This grants the MLD Control the
capability to obtain the greatest yield possible for a dual-axis mechanism. Two MLD sensors determine
which place in the sky has the greatest yield and move the module surfaces into this position. With the
DEGER system mechanism, the control can align the module surfaces to the sun accurately at all times
throughout the entire year. Not only does the control take into account the sun’s irradiation, it also accounts
for reflected light, for example, from snow, water or light-coloured rock, and for the diffuse irradiation
penetrating the clouds – and it does this individually for each system. In practice, this means that if clouds
move in from the west in the afternoon on an otherwise sunny day, the module surface will turn back to
face east based on irradiation. When there is full cloud coverage, the module surfaces will move either into
the horizontal position or into a position with higher irradiation so that the best yields can be obtained in any
weather situation. The control is designed to work in the most efficient way possible, and it moves only for
the purpose of directly increasing the yield.
Sunshine: The DEGER system directly faces the sun all day.
Varying light conditions: Because of different levels of cloudiness, the light conditions in solar parks vary for each DEGER
system. The individual control makes sure every DEGER system is optimally oriented to the brightest source of irradiation.
This guarantees the highest energy yield possible.
Reflecting surface: The DEGER system
uses direct solar irradiation as well as
energy from reflected light.
Partly clouded: In addition to the direct
solar irradiation, diffused light is also
used to maximize the effects.
Overcast sky: The DEGER
systemcatches all the diffused light by
moving to a horizontal position.
