Does wind affect solar photovoltaic panels?
Many previous studies have determined the impact of wind on solar photovoltaic panel arrays, but mainly on land, mountain, or roof solar photovoltaic panels. However, the wind load conditions on the ocean are harsher than those on land, mountains, or lakes, and the flow conditions are more complicated.
How does wind pressure affect a front-row photovoltaic panel?
Pressure distribution along the solar panel profile line. In addition to SP1 being subjected to the main wind load, the wind pressure attenuation of the rest of array a is obvious. Hence, the structure needs to focus on strengthening the structural strength of the front-row photovoltaic panels.
What is the pressure distribution of a solar panel?
Pressure distributions When the wind passes through the solar panel, this exerts a pressure load on the surface of the panel. The pressure load can be described by the following coefficient: (8) C p = 2 F p ρ u 2 S where Cp is the pressure coefficient.
What does a mean in a photovoltaic panel?
A is the projected area of the panel along the pressure direction. ρ is the density of air. u is reference velocity and Fp is pressure measured at the panel. Surface pressure distribution of the average C p on the upper and lower surfaces of the array photovoltaic panels are shown in Fig. 13.
Which area of a photovoltaic panel has the highest wind load?
Obviously, the second area with the highest wind load always occurs at the leading edge of the first reverse-mounted photovoltaic panel (Fig. 12). This mean that pressure distribution on the surface of each photovoltaic panel is largely related to the installation direction of the photovoltaic panel.
Why do photovoltaic panels have lower C p values?
It is observed that the wind load on SP4–6 is significantly reduced since a low-speed region is formed due to the turbulence effect after the wind flows through the SP3, which can be found in Figs. 9 c–e. Therefore, SP4–6 have lower C p values on the surface of the photovoltaic panel due to the weakened wind load.
