Calculate wind load on photovoltaic bracket

What is the wind loading over a solar PV panel system?

Jubayer and Hangan (2014) carried out 3D Reynolds-Averaged Navier–Stokes (RANS) simulations to study the wind loading over a ground mounted solar photovoltaic (PV) panel system with a 25 ° tilt angle. They found that in terms of forces and overturning moments, 45 °, 135 ° and 180 ° represents the critical wind directions.

Why do we need a wind load analysis for floating PV systems?

This information will be useful for the system designer of the floating PV system who wants to know the detailed wind loads on solar panel arrays. Furthermore, this economic analysis could be used for the systems which are installed with regular intervals structures in harsh wind loads.

How important are wind load calculations?

With hurricane-force winds becoming ever more prevalent, wind load calculations are increasingly valuable knowledge for contractors and engineers to have, particularly in the southeast of the US. Solar America Board for Codes and Standards Recommendation

How does wind load affect a floating PV system?

Effect of wind loads on the solar panel array of a floating PV system: (a) forward direction, and (b) backward direction. Furthermore, many studies simply measured the local pressure distributions, however, they have limitation that they could not suggest the better options on the economic aspect.

Why is wind load important for a Floating photovoltaic system?

The wind load is especially important for floating photovoltaic systems. Fig. 2, a floating photovoltaic system is above the sea or a lake. A floating body supports the solar panels by the buoyancy force, which is balanced with the weights of the solar panel and itself.

Does a guide plate affect the wind load on a solar panel?

However, they analyzed the effects of the guide plate in the single solar collector. Bitsuamlak et al. numerically analyzed the wind load on a solar panel array and observed the maximum wind load at an inlet angle of 180°. Thus, they proved that wind load on the 180° should be considered more importantly than other flow directions.
