The sun tracker is single-axis to simplify the mechanics and control and uses a north–south inclined axis with tilt equal to latitude, which is the type of single-axis sun tracker that provides the best energy gains with respect
1 Introduction. In the first utility-scale photovoltaic (PV) installations, the cost of the PV modules clearly exceeded 50% of the total cost of the installation. [] For this reason, two-axis solar tracking systems allowing the optimal perpendicular

The axial direction of a flat uniaxial tracker is generally the north-south axis. The basic principle of its operation is to ensure that the module is at a right angle to the sun''s rays in the east-west
system. The advantage of the dual axis tracker over the single axis is 5 W, while both tracking systems continue to perform 60 W above the fixed. In phase I of this study, it was determined
To simplify the structure and control, single-axis trackers are used more for building integration. Regarding the control method, sun trackers are classified into sensor driver systems, microprocessor driver systems, open-closed loop driver systems, intelligent driver systems, and a combination of any of these systems mentioned.

e usually higher late in the day, when tracker kWh production is much higher than fixed rack kWh production. Among horizontal single-axis tracker , single-row trackers are often preferred over multi-row trackers because they ofer good access for cleaning. Wi hout regula cant losses to specific production in some regions. (Figure 3.)F
A fixed south-oriented PV module (same manufacturer and model to those installed on the tracking structure) was installed close to the sun-tracking prototype with the same tilt as the tracker axis to compare the irradiation collected by the tracking and the fixed system ( Figure 13 ).
A 3-position north–south inclined single-axis sun tracker was designed and tested in [ 14 ], and a low concentration ratio reflector was incorporated to increase the collected irradiation. The experimental results showed an appreciable energy gain compared to a fixed system at an affordable cost.
