Statistical analysis and performance evaluation of Quaid-e-Azam solar park comparing with designed systems using PVsyst and PVWatts

Development of large scale solar power station is a vital step to counter energy crisis in Pakistan. This study is carried out to perform detailed analysis of solar energy harvested from installed solar system (Quid-e-Azam Solar Park Bahawalpur) having DC ratings 100 MW and comparing it with systems designed with different softwares keeping all important parameters same to ensure to reliability of designing. Keeping in view the outcomes of this study it can be concluded that output of solar panels is highly dependent upon various factors like air temperature, wind speed, daily average solar irradiance, humidity etc. Temperature above 25 °C can affect the efficiency 10% to 16% of rated power output. Ambient temperature is always less than module temperature so wind is helpful to draw heat away from panel. Humidity also has inverse relation on performance of solar panels. All results and outcomes are discussed accordingly.
