“…Whilst in the auxiliary bifacial solar cell [15] systems, the bifacial solar cell senses and drives the tracker system to the desired position. Auxiliary solar cells (panels) connected directly to a permanent magnet DC motor are fixed to a rotary axle of the tracker and can both sense and provide energy for tracking.…”

“…In the second way, which is to track the sun, and hence change the angles, provides a higher electricity generation efficiency as the income angle can be more perpendicular [4]. The tracking system can be a single axis, changing only one angle, [5], [6], [7], or multi-axis, which changes both angles [8]. The control of the motors which change the angles can be open loop [9], in which a look-up table is used, or closed loop [10], [11], [12].…”

Turkish government has increased the importance of Konya-Karapınar region by making the area a pilot region for solar energy production. In the near future, the government plans to have a 1 GW solar energy plant in the area. According to this master plan, a pilot solar energy production system was established in the Necmettin Erbakan University campus. A 1000W two-axis tracking and 1000W fixed panels were implemented in this system. In this paper, the performance of these panels are compared and evaluated. 25 years of solar radiation data for Konya is taken from the state meteorology institute, and the produced energy is compared with the predicted values. Tracking panels are found to be approximately 25% more efficient than the fixed panels. However, the maintenance of the tracking panels is observed to be more costly. Moreover periodic cleaning and repairs are found to be very important and another cost factor for both systems. Using the insight from this pilot system, an economic analysis of a large scale 1MW solar energy plant to be established in the campus is performed. For this analysis, fixed panels are considered due to the low investment and maintenance costs and the simplicity of the maintenance work. It is found that the 1MW solar plant will recover the investment cost within 4-5 years and will provide almost 3M$ profit after 20 years.

“…Considering the movement capability, three main types of sun tracker can be found: fixed surfaces [8], single axis tracker [9] and dual axis tracker [10]. Single axis trackers usually use a polar mount for maximum solar efficiency [11].…”

“…This step angle is further magnified at the PV module to more than that which creates a problem that PV module may not be right angle to the sun at all the time. The designed mechanical gear system also removes the problem because at the end gear of the complex gear system, step angle of the motor is converted to a lower value about 0.25' [9]. This enables the PV module to remain always at right angle to the sun and the extracted power is always the maximum.…”

In this research paper, an automatic solar tracker based on gear system is designed and developed. The solar tracker follows the sun from east to west during the day. Driving software has been developed using FLOWCODE and then it is burnt into the microcontroller (PIC 16F72). An intelligent sensor board followed by a sensor circuit has been used to sense the position of the sun.The system has been programmed to detect the intensity of sunlight by a differential arrangement of two LDRs and subsequently actuate the motor to position the solar panel where it can receive maximum sunlight. The solar tracking system is a mechatronic system that integrates electrical and mechanical systems and computer hardware & software. The driving gear system and the structure of the PV module have been developed by using the locally available materials.In our research, the efficiency of this automatic solar tracker is 15% higher than the conventional tracker because of the designing automatic solar tracker and has got it successfully.This reveals that our system is compatible with the additional energy production.
