Local and overall wind pressure and force coefficients for solar panels
Three model panels equipped with pressure taps on both surfaces (36 in total) for point and area-averaged pressure measurements were used. Pressure and force coefficients were
The pressure at the top is minimal, averaging 100.78 kPa, while at the bottom, it is highest, averaging 102.48 kPa. Additionally, lower pressure is observed on the sides of the solar photovoltaic panel.
When considering factors such as solar irradiance angles and wind direction and force, it may be beneficial to consider installing solar photovoltaic panels facing the wind at angles of 30° and 45°, or at a 60° angle facing the leeward direction, to minimize the impact of wind loading on the solar photovoltaic panels.
In general, the pressure distribution on the solar photovoltaic panel is affected by multiple elements, such as the supporting structure, the method of installation, and the surrounding environment. The rational design and optimization of these factors are capable of enhancing the stability and durability of the solar photovoltaic panel.
In order to measure the wind loads applied on the solar panels, 36 pressure taps in total were attached on the panels measuring the pressure on the upper and lower surface of the panel. Each panel was equipped with 12 pressure taps, 6 on each side connected with tubing that passed inside the building through the roof.
