Energy, Environmental and Economic Study of Different Solar Water Heating Systems in Different Moroccan Climate Zones

This article focuses on the prediction of thermal, environmental and economic performance of forced circulation solar water heating systems applied to residential buildings in different climates of Morocco to evaluate the favorable collector technology for each climatic zone. The proposed analysis concerns two thermal collectors marketed in Morocco (flat plate collectors (FPC) and evacuated tube collectors (ETC)). Annual simulations are performed using the TRNSYS and MATLAB software by considering a typical meteorological year (TMY) for all zones. The energy and environmental performance of the two systems was compared to monthly and yearly basis. It is found that high values of solar fraction and collector efficiency can be reached in almost the studied regions with the preference of using (ETC). All Moroccan climatic zones have a significant potential in the application of SWH systems and that ETC technology is more suitable from an energy, environmental and economic point of view.
