Your innovative contact for all kinds of solar power plants

Solar tower power plants

Heliostats are used to reach higher temperatures. They focus the sunlight onto solar towers, concentrating the sun’s rays. Intelligent systems ensure that the heliostats follow the sun’s movements – maximising the yield. HYDAC is always at your side as a partner with expertise in development and systems. Global yet local support.

Parabolic trough power plants

Indirect electricity generation thanks to curved parabolic reflectors – the thermal oil in the parabolic trough is heated by the concentrated sunlight. The steam generated as a result of this drives a turbine in the parabolic trough power plants. To ensure that this solar thermal process runs smoothly, we support you with our innovative solutions for turbines, solar tracking and sensors. Based on decades of expertise in power plant technology.

Photovoltaic power plants

Photovoltaic systems are used to directly convert solar energy into electrical energy. This cost-effective technology is already being used extensively in sun-rich desert regions and land areas. Pioneering components and systems from HYDAC enable you to increase your solar park's availability. Benefit from our expertise in sensors, cooling and temperature control.

Other solar thermal power plants

As one of the renewable energies, solar thermal energy offers the widest range of applications. This dynamic industry doesn’t stand still: new ways of using the sun’s energy sustainably and making solar cells more efficient are constantly being developed. Whether it’s dish Stirling, linear Fresnel or other types of solar thermal power plants (commonly called CSP power plants) – HYDAC will be at your side to support you with the technologies of the future.


Solar thermal power plants and large photovoltaic systems are playing a central role in the transition to renewable energy and are showing great potential. HYDAC supports you on this journey with systems and components such as optimised filter systems and lubrication systems. For a longer service life of your components, increased availability and sustainable conservation of resources.
