Abstract:

This paper investigates the performance of a 22.8kW PV solar system for the eco-house in the Higher College of Technology in Oman. The house is located in Muscat at 23.579°N, 58.432°E. Data measurements from October 2017 to September 2018 were used to analyze different ambient temperature conditions, wind, daytime, and solar irradiation. The soiling and dust effects were also considered. The solar system is grid-connected, and the total annual net energy out of the imported and exported energy is calculated and found equal to 1540kWh, which shows a positive net-zero house compared to the traditional Omani house. The average monthly generated solar energy varied between 1800kWh and 4500kWh at the optimum weather and clean solar panels case. The annual average efficiency of the solar system was found equal to 5.44%.
