Abstract:In the 21th century, one of the biggest problems that the world faces is energy provision. Today, the way that most countries use for energy production is not clean and continuous. The most obvious proof for that is the change in the climate. The amount of CO 2 (carbon dioxide) that is caused by fossil fuel burning increases day by day and this situation creates the greenhouse effect and change in the climate. The sun is one of the best solutions to this problem. It is not only clean and continuous, but also available anywhere, anytime. However, the efficiency of a photovoltaic system is directly related to the amount of solar energy acquired by the system which means that, it is necessary to follow the sun to have a high efficient system. There are two types of trackers that follow the sun and there are several ways to build them. In this paper, solar tracker designs are examined and a new dual axis solar tracker design is given.

“…3, it can be seen that more voltage is produced and more power is obtained by using the designed system compared to classical methods. A low-cost and programmable system which tracks the sun on both azimuth and altitude angles in real time and which does not require photo sensors was developed in the present study [9]. The PV panel tracking system, which was developed as a microcontroller-based system, was tested in Diyarbakir province in Turkey and it was seen that more energy was obtained from the sun in the developed system when compared to fixed systems.…”

Abstract-In this study, we investigated the efficiency of our own two-axis solar tracking photovoltaic system which designed by us according to a fixed system. The system's energy consumption was minimized by using tipper motor in the two-axis solar tracking system. Both systems were mounted in the same place to compare two-axis tracking system's efficiency with fixed system's efficiency fully and used the same breed panels, charge regulator, measurement device and battery. It was observed that Two-axis motion system efficiency was more than fixed system 31.67% over an annual average. This efficiency was measured on some days up to 70% during the winter months and up to 11% during the summer months.

Concentrator photovoltaic modules are a promising technology for highly efficient solar energy conversion. This system presents several advantages due to additional degrees of freedom that has been provided by the spectral separation such as cost and mass reduction, increase in the incident solar flux on PV cells and performances. This paper has proposed a unique photovoltaic solar cell system that consists of semi-Fresnel lens convergent structure and a novel two axis sun tracking module to enhance the efficiency of solar cell by using less cell area and energy losses. The grooves of this lens are calculated according to the refraction and convergent angles of the light easy for perpendicular incidence angle. The update time interval during tracking causes misalignment of the lens' optical axis versus the sunrays. Then an inventive sun-tracking method is introduced to adjust the module so that the incident rays are always perpendicular to the module's surface. As a result, all rays will be refracted with the predetermined angles. This way the focus area is reduced and smaller cells can be used. We also mentioned different module connections in order to provide compensation method during losses, for networks and power systems. Experimental results show that using semi-Fresnel lens, along with the sun-tracking method increases the efficiency of PV panel.
