Optimal coupling of a PEM electrolyser to a PV generator: Case of Adrar

Abstract

An optimization method is proposed and applied to study a PV-electrolyzer system consisting of Solarex MSX60 modules and PEM electrolyser H-Tec StaXX7 stacks. A total of 41 series-parallel combinations of PV modules and electrolyser stacks were analyzed. The configuration of 05 stacks of electrolyser in series connected with 04 PV modules in series is identified as optimal configuration for the site of Adrar. This configuration presented a value of 0.2 % in terms of annual energy losses and an annual production of hydrogen of 125 m3.
