Abstract: Energy demand overall the world increases rapidlyin various sectors, one of the highest energy consumption sector is thebuilding sector. Installation of PV systems is one of the solutions to coverthis demand and will serve in promoting energy efficiency in the Palestinianmunicipalities in decreasing the electricity bill, and using the saved money inconstructing new projects and improving the level of services provided tocitizens. In this work, Al-Dahriya municipality has been taken as a case study.The municipality installed 20 KW of photovoltaic panels on the roof of the mainbuilding in 2015. The cumulative values for one year after installation the PVsystem represent a total consumed electricity by the main building was 71,506 kw,while the total generated power by the PV system that transferred to buildingwas 32,664 kw, and 5323 kw exported to the grid with total generated power byPV system was 37,987 kw. The participation of energy that produced by the photovoltaic system is53.12 of the total power demand of the building. The value of generated powervaries between the summer months and winter months through the difference ofthe solar radiation intensity and the number of shinning hours, the largestreading of solar radiation intensity is in thesummer months. The study ensures the importance of applying selected thermalinsulation materials in order to decrease the heat transfer through theboundary wall of the building. Furthermore, this study covers the otherbuildings and utilities of municipality and recommended with certain issues in order to promote energy efficiency.
