Measurement the Performance and the Current Variations of anExperimental Solar Cell System in Al-Marj City

In this research, we formed a solar cell system which consists of three solar panels inclined off the horizon at a 300 angle, and the eastern and western panels inclined at a 450 angle, then these panels were connected to a computer via a connection card that converts analog signals (resulting from cell panels) to digital signals that are collected in excel files. The variations of the current, resulting from the panels, are measured according to the whole year. The collected data are taken, then the results are compiled starting from January 2020 to December 2020 based on the studies we conducted, July was determined as the best month of the year in terms of the efficiency of the solar cells. In addition, this work confirms that the studied region in particular and Libya in general represents a good incubator for renewable energies research, especially solar energy, and a promising and encouraging future in these fields.
