Motion plastics for the photovoltaic industry

Strong UV radiation, heat, wind, dust: solar plants have to operate under extreme environmental conditions. igus offers different and customised solutions that meet these exact requirements. Our motion plastics are absolutely ideal with their long service life, freedom from maintenance, lubrication and low costs. Application scenarios for dirt-resistant and lubrication-free plain and spherical bearings are:

• Tracking systems,
• Floating photovoltaic plants (floating PV) 
• Cleaning systems.

igubal® solar pillow block bearings convince in the lab test

In the company's own 3,800 square metre igus® test laboratory, the service life, wear resistance and load capacity of igubal® pillow block bearings for solar modules were examined under real loads of the daily motion sequence, simulated in a time-lapse.
 
The number of movements achieved under a load of 1.5 tons corresponded to a service life of 72 years.

25 years of service life in dust, heat and UV radiation, in the best case without failures and with minimised maintenance requirements: in this white paper, you can read about the requirements placed on the bearings of single-axis solar trackers and the solutions we offer for this.

Reliable tracking with igubal pillow block bearings

To ensure that solar unit daily tracking movement works perfectly, the company uses our robust igubal ESQM pillow block bearings – a "fit and forget" solution, since they are maintenance-free throughout their 25-year service life.

Withstand all weather conditions: plain bearings in PV trackers

Tracking systems from TecnoSun Solar Systems score highly in terms of cost efficiency thanks to their low installation height. iglidur P plain bearings are used in the traction ring. They withstand all weathers, are dirt-resistant and can easily withstand high loads caused by snow.

Clean bearing solutions for solar panel cleaning equipment

The remote-controlled cleaner from TG hyLIFT removes fine dust, bird droppings and lichen from solar surfaces. Media-resistant iglidur P plain bearings are used in the wheels and self-aligning igubal fixed flange bearings in the rotating brush, which work without any problems with prolonged contact with water and cleaning agents.
