Deger Energie's new tracking system Deger Energie, located in the German city of Horb am Neckar, presented a reconfigured and export-ready version of its 1997 Sol-Traker tracking system at the Middle East Electricity fair in Dubai in February.
The Sol-Traker 1000 EL works with all standard solar
module types and can handle a total module surface area of up to 10 m²
and a maximum weight of 300 kg; the Sol-Traker 1200 EL can handle 12
m² and 350 kg. The biaxial tracking system is steered independently by
sensors. In rainy or foggy weather, the system automatically tips the
module surfaces into a horizontal position to best exploit the
incoming diffuse light.
In contrast to the original Sol-Traker series, which
was composed of three separate pieces, the new system consists of
seven parts and is 100 kg lighter, so that Deger Energie can reduce
shipment costs for the customer while maintaining the product price.
The complete system consists of a 3 m long mast, a drive mechanism,
the steering electronics, and the structural design. Wholesale prices
for both systems are between €1,500 and E€1,900 ($1,300 and $1,650).
Hence, if one wants to maximize the energy yield per invested euro, it
is still more practical to purchase additional solar modules, at least
in Germany offering a high feed-in tariff for PV.
