Sun, Sand and NEW Safety

robot cleans on a solar penal

The sun has heated up the air and the ground throughout the day, and looking into the distance, you can only see a haze over the asphalt. This is not an uncommon sight, especially on warm summer days. The power of the glowing celestial body is enormous, despite the fact that it's almost 150 million kilometers from the Earth. This energy is used by solar power plants. In addition to hydrogen and wind turbines, generating energy using the power of the sun is regarded as an important measure in reversing climate change. Especially in sunny regions, large-scale photovoltaic systems with areas covering several thousand meters squared are therefore being developed to achieve the highest possible yields. The downside of this, however, is the time-consuming cleaning these large-scale installations require. This is especially applicable in dry regions or areas near agriculture where sand, dust, and dirt particles contaminate the solar panels. This dirt not only reduces energy yield, but also damages seals and surfaces. Regular cleaning is therefore required to optimize the energy yield and increase the longevity of photovoltaic systems.

hyCLEANER GmbH & Co. KG, headquartered in Gronau, Westphalia, has taken on the task of supporting plant operators and cleaning companies in this process, and has developed the hyCLEANER solarROBOT® pro. Originally designed for glass roofs, the innovative solarROBOT pro is now being adopted for cleaning large-scale solar plants with its partially automated and robot-supported system—contributing to greater energy yield and efficiency, and increasing safety during maintenance.

Effective Cleaning on different solar penal inclination

Further the solarROBOT is able to clean all the different solar penals inclinations with innovative ultrasonic sensors from Pepperl+Fuchs. In addition to efficiency and high-performance cleaning, another aspect was also very important to the creators during the conception: "The impetus for the development of the solarROBOT was not only to make the work easier, but also to increase safety for people and the environment," explains Celina Kneiber, Managing Director at hyCLEANER.

potential of solar power

The sun is a gigantic source of energy. What arrives on earth every year could cover the world's energy demand of 150 billion kilowatt hours millions of times. The fact that direct solar energy use only contributes a small part to this is due to the relatively low power density. On the other hand, the sun gives us a whole list of benefits – from free energy to good breathing air. Get to know the many possible uses of free and healthy solar energy. We have divided them into active and passive, direct and indirect forms of use.
