Why did DESERT-VISION choose the FRESNEL technology?
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. Parabolic solar mirror power plant Parabolic solar mirror Very complex mirror construction Complex assembly Defocusing due to wind loads Fragile movable receiver tube Very prone to errors Extreme maintenance costs 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.
