Why is damping important for solar trackers?

In the posts of Atreydes Engineering, we have remarked the importance of damping for solar trackers (ξ) which allows delaying, mitigating or eliminating aeroelastic phenomena in the design of single-axis solar trackers.

Does a tracker have a linear damper?

Linear dampers need a fixed point to transmit the load generated by the tracker rotational speed, so it is only possible to damp the tracker under its pillars, which will be used to transmit the load. So, each outer pillar will have a linear damper.

Do trackers need torsional damping?

Since tracker structures cannot provide this damping by itself, linear dampers will therefore make this functionality, as they are cheap and easy to install components. It is important to remember that a tracker needs torsional damping which must be provided by linear dampers.

What are the physical dampers required for a tracker?

Here, the physical dampers required for this purpose will be defined according to the results of the equations to prevent torsional galloping and the performance of vortex shedding analysis to avoid resonance or at least excessive vibration introducing high stresses in the tracker components under design wind speeds.

What parts should a solar tracker include?

By now, you probably have an idea of which parts you have to prioritize: these can include solar panels, solar inverters, solar charge controllers, and solar batteries. But you have to add one more thing to that list, and that would be solar trackers. I. What Is A Solar Tracker? II. Top Manufacturers or Wholesalers of Solar Trackers in China III.

How does a PV tracking system work?

The tracking system is driven by a single engine. The P V modules rotate from East to West on a horizontal axis, following the Sun’s daily movement. This configuration has a limited range of motion angle (β max). This range depends on the manufacturer. Typical values are β max = ± 60 (°) .
