Simulation and Evaluation of The Solar Energy Systems in The Public Buildings in The City of Tripoli-Libya : Mosques Sector

Abstract

Mosques are classified as one of the most attractive places for the Libyan people during prayer times, where electrical power converted into many energy types. Hot water is required for ablution during the cold season, which occupies 5 months per year approximately. Where electrical power is utilized to provide hot water demand, the reduction of electricity use of mosques is the target of this work.This paper, represents a study of ten mosques in Tripoli, Libya to examine their suitability for alternative energy applications that includes solar thermal water heating and photovoltaic electrical power generation applications in collaboration with the General Authority of Islamic Affairs and CSERS states. Therefore, a detailed study is performed for site shading probability during the year using Climate Consultant 6.0 software, and Sketchup Make 2017. Furthermore, the solar water heating system is designed by (T*SOL Pro 5.5) design and simulation software. The resultant has illustrated that the employing of forced circulation solar water heating systems for their high capacities. where thermosyphon systems could fail to fulfil water heating load in the studied mosques, due to the presence of the surrounding buildings shade among winter and the high water heating load of such crowded mosques. However, the operation of the critical electrical loads is performed by standalone PV system.
