It is the only solar mirror construction that forms a solid flat structure.
This is the basic requirement for the huge sun-protected oases - sun cities.
Fresnel - Solar mirror
The DESERT-VISION solar mirror fields are fully AI-supported and operate
completely autonomously.
During the night, the mirrors rotate 180 degrees into a protective and parked position.
In this position, an autonomous robot moves beneath the mirrors, performing both
cleaning and measurement in a single operation. The robot cleans the mirrors
thoroughly using a special, contactless process, while simultaneously conducting
optical measurements to assess mirror efficiency and identify any defects. Thanks to
an innovative recycling process, the cleaning requires virtually no water. Damaged
mirrors can be replaced within minutes.
This fully automated operation of the entire mirror field makes the operation of
DESERT-VISION power plants exceptionally cost-efficient. The simple and robust
linear system technology allows for particularly straightforward and cost-effective
installation. Additionally, the flat arrangement of the mirrors enables dual usage of the
installation area – a unique advantage compared to other technologies.
The decision to use linear mirror systems is based on decades of experience with
various solar mirror systems. The use of automated linear mirror fields is what makes
the economical operation of large-scale solar mirror fields possible, establishing a
pioneering model for the sustainable operation of solar power plants.
Tower power plant
Thousands of individual mirrors - so-called heliostats - are set up around the tower.
Over 1000°C working temperature makes the receiver at the top of the tower very
vulnerable to repair.
Requires a lot of space
Heliostats Solar Mirrors
Very complex tracking mechanism for each of the thousands of mirrors
Very susceptible to mechanical failure and defocusing
Extremely high maintenance
The frequent and resource-intensive cleaning of solar mirrors poses a significant
challenge, particularly in arid regions where water scarcity is a critical issue.
Traditional cleaning methods often consume thousands of cubic meters of water
annually to maintain the reflectivity and efficiency of the mirrors. This excessive water
usage is not only unsustainable but also impractical in areas with limited or non-
existent water resources, such as desert environments.
