Study of the long-term performance of a solar water heater

Energy is the source of all human development, its use is indispensable for man, but its availability causes a great problem until now either its cost is high or its source is polluting and even limited. In recent years man has begun to develop renewable energy sources such as solar energy. The present work is part of the general framework of the study and realization of a test bench for solar water heaters. Based on climatic data in Algeria (BOUSMAIL) in order to have a good device to market on the Algerian market. In this sense, a numerical approach of modeling and analysis aiming at extracting information and performances for the prototype realized by using the software Meteonorm and SAM which are powerful tools of analysis. By comparing and interpreting the results, we must repair and improve anything that seems to be an obstacle to the proper functioning of the water heater.
