| Abstract This paper presents the design and implementation of an experimental study of a two-axis (Azimuth and Altitude) automatic control solar tracking system to measure the solar radiation in an inexpensive way by a tracking solar PV panel according to the direction of the beam propagation of the solar radiation from dawn to dusk. The designed tracking system consists of four sensors (LDR) and a programmable logic controller (PLC) which controls two DC servomotors with control software designed for this purpose to move the system panel according to the information from the input sensors, keeping the panel always perpendicular to sun rays. The designed software contains also a backup program (override part of the software) which controls the tracker in adverse weather conditions (cloudy or partly cloudy). To investigate the effect of using two-axis sun tracker system in measuring the solar radiation, an experimental study is carried out to evaluate its performance in the territory of Mosul Technical Institute. | ||
