Abstract
We present the analysis of the size and angle configuration of a solar photovoltaic (PV) plant connected to an alkaline electrolyzer without electrical storage nor support from the grid. Our approach is based on using the available energy in the most efficient way. To reach our objective, we allocated the available PV power to the stack and auxiliary components, then determined the produced hydrogen in one year. By defining 4 indicators, we determine that the PV plant should be oversized 1.6 times the rated power of the electrolysis stack. The orientation analysis of the PV modules shows that the optimal angles determined for maximum PV yield are not the same if other indicators are used and many of them are in conflict.
