Theoverall system efficiency is determined by measuring the solar irradiance as thesource of the input energy, and the amount of hydrogen produced as the source ofthe output energy. Hence, the losses through the Photo-Voltaic (PV) cell,connecting wires, and the water electrolyzer, are all considered in the presentstudy. Moreover, the effects of the gab width distance and the separators' types,on the overall system efficiency are also presented. It is found that, the higher theelectrolyzer efficiency, the higher is the overall system efficiency at almostconditions. The significant reduction in system efficiency may be due to losses ofthe energy conversion through the PV cell and the electrical losses in theconnecting wires. Though, the electrolyzer efficiency reaches 90% and themaximum overall system efficiency of 1.7% is barely achieved. %U https://amme.journals.ekb.eg/article_34983_7fcba692ff543b67b7c8ea25d7b84717.pdf
