It is known that, the available power from a photovoltaic system is unpredicted and
differs with climatic changes, so it has an intermittent nature, in other words it is unable to
supply the load continuously and steadily. Because of that, storage
methods of its energy
must be studied to use it again in a way that could be predicted. Hydrogen production is
one of these methods by connecting the PV system to water electrolysers, and this stored
hydrogen could be used either in fuel cells or burning it to get thermal energy. This study
focuses on PV system and the available energy taken from it, and the electrolysers and its
requirements and products. Making a mathematical model would be done and plotting the
curves that represent the system by programming it using MATLAB. A simple numeral
example that clears the system would be calculated. By this way, the energy efficiency
would be between 23 to 67 % according to the way the produced hydrogen is used.
