“…Analysis of these data revealed that the sun tracker generated 39.2% more energy than the fixed slope system. When compared, the generated energy efficiency is slightly less than [20,21,23]. The total generated energy is high than [23] also consumed energy by DC motors higher.…”

“…Naturally, it is possible only solar noon every day. By adjusting the PV panel to the sun starting from sunrise to sunset, the PV panel output performance may rise up to 46% when compared with fixed slope PV panel [20]. Sun rays' incidence angle changes largely diurnally and slightly seasonally.…”

Many mechatronic systems have challenging control difficulties due to the high nonlinear structures and time-varying dynamic behaviors. In addition to these, there are external disturbances, which cannot be predicted and change according to uncontrolled working environments. Conventional controllers are insufficient to solve the aforementioned problems and to compensate the environmental disturbances. Therefore, adaptive controllers have been proposed as a solution to these inefficiencies of conventional controllers. Adaptive control is applied for solving the control problem of the mechatronic sun tracker that ensures the movement of the mechanism to harvest maximum energy coming from solar to the PV module surface during the sunshine duration. For this type of control problems, conventional controllers are very limited and they have a lot of deficiencies. The adaptive mechanism governed by an adaptation law is the heart of any adaptive controller. We establish the adaptation law for the plant control system using Lyapunov stability theory. This adaptation law is precise for a generic second-order system; hence, it is obviously applicable for adaptive control of other second-order systems in different realms, such as industrial production system, military, and robotics.

“…b. The literature presents some constructive solutions of tracking mechanisms, mainly for individual PV panels [10,14,18,19,23,28,30]. In the case of the arrays/groups of panels there are only summary descriptions of different producers for such systems, for simple topologies (line -string) and single-axis systems (M=1) [47].…”

This paper deals with a review on the solar trackers used for increasing the energetic efficiency of the photovoltaic (PV) strings. To begin with, the context from which the utility of the tracking mechanisms emerges is presented. The study continues with the systematization of the PV systems according to the structure that is oriented (i.e. the configuration in which the PV panels are disposed / arranged), presenting also the main advantages and disadvantages of the existing structures. Thus, it is retained as a solution for deepening the research that of the simultaneous orientation of the PV panels arranged in a string-like configuration. Afterwards, the study is focused on the main components that are taken into account in the design process of the tracking systems for PV strings, such as the tracking mode, the evaluation of the solar energy potential (involving the modelling of the solar radiation), the emplacement/disposing scheme of the panels in different array configurations, the mechanical and control devices of the solar trackers.

This paper investigates exergy analysis of a solar photovoltaic system that is designed, constructed and tested in Mechanical engineering department, Salahaddin University-Erbil 36°14″N, 44°01′E.Exergy analysis is used to estimate the exergy destruction losses during the PV module conversion process by using the second law of thermodynamics and to refine and predict the variations in solar photovoltaic behaviour. The electrical and operating considerations of a photovoltaic module include total solar irradiation, maximum generated power by the system, voltage, open-circuit voltage, current, short circuit current, cell temperature, and ambient temperature.To find sun's position in the sky LDRs (light dependent resistors) are used as an input feedback and rotate the PV module to track the sun using motors and actuators. Quantity of four LDRs mounted on the solar tracking system frame used to find the light intension difference between all four directions north, south, east and west. The system is automatically controlled by PLC system and is able to rotate the photovoltaic module to follow altitude angle of the sun between 0o to 90o using a 24 inches 36V DC actuator and a 12V high torque DC motor is used to rotate the photovoltaic module toward east and west to follow the sun's azimuth angle for 360 degrees.The results show that most of the solar irradiance value is dissipated and not entered to the PV module. However, this dissipation of energy results in decreasing the value of the energy and exergy input to the system. The increase in the value of the energy and exergy losses from the morning to about the noon time is because of increasing of the surface temperature of the solar module. From the output of this work, the authors suggested that the module should be reconstructed and redesigned which is suitable for the Kurdistan environment. The suitable one of the PV is to be designed in a way that the temperature rise within the module is not increased the standard level which is 25 ºC, however the temperature rise is will reach about 50 ºC in the summer. That is why the authors prefer to reconstruct the module.
