dc.description.abstractA photovoltaic system consists of an array, a storage medium and elements for power conditioning. Many photovoltaic systems operate in a stand-alone mode and the total energy demand is met by the output of the photovoltaic array. The output of the photovoltaic system fluctuates and is unpredictable for many applications making some forms of energy storage or backup system necessary. The role of storage medium is to store the excess energy produced by the photovoltaic array, to absorb momentary power peaks and to supply energy during sunless periods or during night. One of the storage modes is the use of electrochemical techniques, with batteries and water electrolysis as the most important examples. In this paper, we report the optimal design for a stand-alone hydrogen system with the volume of hydrogen produced against current as regards the concentration of electrolysis cell. Operating characteristics of a small capacity solar hydrogen system have been determined and also demonstrated that the I-V characteristics of the batteryphotovoltaic module and electrolysis cell are influenced by variations in the concentration of the electrolysis cell, which in turn determines the amount of current that flows through it. A 50W photovoltaic panel rated as 17.4V, 2.87A yielded a maximum volume of about 8.6ml per minute for 1.0M cell concentration. Numerical simulation was used to compare the experimental results and also the possibility of increasing the cost-effective yield of hydrogen.
