What are the benefits of solar energy?

Reduces electricity bills Lowers carbon footprint Increases property value Promotes energy independence

Wear resistant products 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.
