Products used for renewable energy

What is renewable energy?

Renewable energy is collected from renewable sources, such as wind turbines and solar panels. Generating energy, especially from renewable energy sources, requires reliable and durable technological solutions.

In the process, the different systems are often exposed to extreme environmental conditions, such as UV radiation, fluctuations in temperature, strong winds, dirt and dust, and have to withstand these for years.

Tailored to the specific system, we offer you special solutions made of high-performance polymers, which can help you improve your technology, optimise your system and reduce costs.

Requirements for the bearings of single-axis solar trackers

The bearings of single-axis solar trackers are exposed to adverse environmental conditions over a period of 25 years, ideally without failures and with as little maintenance as possible. The bearings' load profile includes UV radiation, high and low temperatures as well as dirt, sand and dust. Under these conditions, a pillow block bearing made of high-performance plastic with incorporated lubricant proves its worth.

Withstand all weather conditions: plain bearings in PV trackers
Tracking systems by TecnoSun Solar Systems AG convince due to their cost efficiency thanks to low installation height. For the traction ring, the company required low-maintenance bearings that would withstand decades of operation in all sorts of weather conditions. At igus, they found what they were looking for: dry-running iglidur P plain bearings are maintenance-free, resistant to dirt and extreme weather conditions and withstand heavy loads, should they be covered in thick layers of snow.

Clean bearing solutions for solar panel cleaning equipment
TG hyLIFT GmbH has developed a remote-controlled cleaner, which rolls along up to 100-metre long solar panels, removing fine dust, bird droppings and lichens. In the wheels, the engineers relied on media-resistant iglidur P plain bearings. In the rotating brush, wear-resistant igubal fixed flange bearings are used as they compensate for alignment errors and operate reliably, even when in continuous contact with water and detergents. Due to their dry operation, igus components are practically maintenance-free.
