Renewable energies with wind energy and photovoltaics

Here you will find news for the developers of Renewable energy Industries with photovoltaic systems, wind power plants and hydropower. We report on products, systems and technologies for geothermal energy, solar technology, biomass, heat and hydropower plants - everything you need to know to develop a CO₂ friendly power engineering.

Renewable energies are winning under the sign of Energy transition and thanks to their government funding increasingly important. In 2019 the Power generation from biomass, wind, heat, hydropower and photovoltaics almost 43% of the annual electricity consumption in Germany. The share grew by almost 5% from 38,2% in 2018. Above all, renewable energy is important for downstream industries such as Automotive industry. Because an electric car only makes sense if the electricity from renewable electricity generation is used. 

Brand new renewable energy technology

We report on supplier components for the construction and development of systems for energy generation using wind power, solar energy, hydropower and biotechnology.

From the gondola to the tower of the wind turbine

01.09.2023 | heli cable has a versatile range of products for the electrical equipment of wind turbines. From flexible aluminum cables that can be seamlessly integrated into the tower to heat-resistant cables for generator connections - the solutions cover all aspects of the wind industry. The portfolio includes light and flexible aluminum cables, which can be pulled into the tower in one length without costly interfaces.

Photovoltaic park in Franconia supplies Schaeffler plants

Schaeffler has a Photovoltaics Park in the Franconian town of Kammerstein (Roth district) from BayWa re AG, a global leader in renewable energies. The photovoltaic park extends over a total area of ​​10,7 ha and generates a total output of 9,9MW peak. This covers the electricity requirements of around 2% of the German locations.

Dynamic inclination sensor for wind turbines

With the Inclinometer IMU F99 from Pepperl + Fuchs the rotational speed of wind turbines can be determined or the acceleration rates of rotor blades can be monitored. These in turn are subject to fluctuations as soon as unwanted icing occurs rotor blades deposited. In this way, the rotational speed can be regulated and predictive maintenance of the wind turbine can be implemented. 

New evaluation logics on safety relays for wind turbines

Schmersal presented on the SPS 2022 new variants of its multifunctional safety relays Series SRB-E. These product lines come together with the compact safety controller ProtectSelect for a high level of security, which is easy to use and highly flexible. This makes the products very suitable for elevators in wind turbines.
