“…The purpose of this study was to find out the effect of a windy area on the power production of a photovoltaic (PV) plant. An air flow study shows that in the under‐examination hilly area, hills play a significant role for wind farms (WFs) as they tend to increase the wind speed (compared with the incoming air flow) because of the obstructions on the incoming wind and therefore are usually preferable in order the power output to be increased (speed‐up effect) . In coastal hilly areas, the speed‐up effect accompanied with the sea breeze phenomenon, which usually affects coastal areas, has a positive impact on the wind speed results of the area, something which accents hilly peninsular sites as suitable for WF development.…”

In this paper, a detailed exergetic analysis based on the variation of meteorological parameters was performed for a solar power generation system. All wind and solar energy and exergy characteristics were examined in order to identify the variables that affect the power output of the photovoltaic (PV) system. Atmospheric variables such as air temperature, humidity and wind speed and their effects, shadow effects, tracking losses, and low radiation losses of the PV power output were investigated aiming at identifying the real and net solar energy output. It was shown that some usually disregarded atmospheric variables in planning new PV plants, in fact, do play a significant role on the plant's overall exergetic efficiency as wind chill temperature. The solar potential around a windy coastal hilly area was studied and presented on the basis of field measurements and simulations. Understanding atmospheric parameters variation appears to be of great importance for estimating correctly and trustworthy the energy yield, and special focus was given to that in this paper.
