In this study, wind tunnel tests were conducted to systematically investigate the wind loading characteristics of solar panels on the square roof of a tall building. Both the isolated and 3 × 3 arrayed panels (nine zones on the roof) were studied by analyzing the mean and peak pressure/panel force coefficients.
It is important to mention that such velocity fluctuations are lower due to the presence of the roof-mounted solar panels, and note that the presence of the solar panels does not affect significantly the wind flow below the threshold TI =0.15 in comparison with the empty roof.
Solar panels are mounted on building roofs worldwide due to the advantage of harnessing solar energy close to consumers without requiring additional land. In the past, solar panels were mainly installed on grounds , , , , , , and roofs of low-rise buildings , , , , , .
The shading effect of the photovoltaic panels makes the roof temperature in the shading area higher than that in the unshaded area. This is because the photovoltaic panels store a certain amount of heat during the day when the irradiation is abundant, radiating heat with the shading area at night, causing its temperature to rise.
However, the roofs of tall buildings are characterized by large wind speeds and complex turbulent flows, which may severely damage solar panels. Therefore, the assessment of the wind loads on solar panels is of great importance for design purpose , , .
In the absence of photovoltaic (PV) panels, the heat absorbed by a cool roof (characterized by high reflectivity) is reduced by 65.6% compared to a conventional roof (with low reflectivity). However, once PV panels are installed, the disparity in heat gain between roofs with varying reflectivity levels is narrowed to approximately 10%.

Due to the complementarity of solar energy and PV wind panel, the capacity is 600 kW, and with 8 turbines is 95 kW. Wind speeds are higher in winter than in summer, so it partially compensates for the reduction in power generation from the PV panel. During the summer, when wind power generation is lower, it offsets the PV panel. The annual electricity …

The efficiency (η PV) of a solar PV system, indicating the ratio of converted solar energy into electrical energy, can be calculated using equation [10]: (4) η P V = P max / P i n c where P max is the maximum power output of the solar panel and P inc is the incoming solar power. Efficiency can be influenced by factors like temperature, solar irradiance, and material …
