For solar bearing, UHMWPE exhibits superior wear properties and has a coefficient of friction comparable to that of PTFE. Compared with PA6, UHMWPE is 20% lighter and is also capable of taking high loads. Finally, a price comparison would also show that solar tracker bearing made of  UHMW  is a more cost-effective solution.

Photovoltaic (PV) applications require durable materials that can perform outdoors for long durations, often up to 25 years. Photovoltaic systems and components include solar tracking systems and their tracker bearing components. These tracking systems allow PV panels to follow the sun throughout the day, generating maximum energy. The key component that allows these systems to move is the solar tracker bearings.  The materials required for these applications should have low-friction and be able to maintain its toughness and other properties under weatherable conditions for long durations of time.

The world’s demand for solar energy is rapidly increasing. Generating as much power as possible while minimizing costs is critical. Solar tracker which is a device that orients solar panel toward the sun can increase solar panel’s efficiency by as much as 40%. Bearings for solar tracker must be reliable to maximum availability and productivity.
