The output power generated by the solar photovoltaic panel is directly proportional to the amount of solar energy it receives. Therefore, for maximum efficiency, a solar photovoltaic panel must be perpendicular to the sun. As a result of this, a tracking device is required to ensure that solar panels are always directly perpendicular to the direct component of the sun. Such a tracking device is referred to as a sun seeker. This research work describes the development of a single-axis sun seeker using three sensors. Light-dependent resistors are used as sensors. The light intensity received by two of the sensors is compared by two comparators and an appropriate signal is sent to the driving mechanism which moves the solar panel tray until the right and left sensors receive an equal amount of light intensity. The middle sensor was designed to activate the speed control unit of the system when it senses the required light intensity. The whole system runs on a 12V rechargeable battery. A battery charger circuit with automatic cut-off was incorporated to the design to keep the battery topped-up and to prevent overcharging.

Detailed analysis of microcontroller (μC)-based smart dual-axis automatic solar tracking system utilizable for different purpose is presented in this article. Working of the proposed smart tracking system is based on the automatic rotation of photovoltaic (PV) panel depending on the intensity of sunlight. It will help in maintaining the alignment of PV panels with the sunlight to obtain maximum solar power at any instance. Intensity of sunlight on a particular alignment of solar PV panel varies throughout the day. As the intensity of light on PV panel decreases, the proposed smart tracking system has the intelligence to automatically redirect the panel alignment to get maximum intensity of light. Four light-dependent resistor (LDR) sensors are placed on the surface of the PV panel to detect the intensity of light. Two servomotors are employed in the backside of PV panel system to align the panel with maximum luminous intensity. Design and construction of the proposed tracking system is presented to measure the efficiency over the fixed PV panel. Experimental results indicate that the power output of the PV system, using the proposed tracking system, is increased up to 19.73% when compared to the traditional fixed PV panel. The efficiency of the proposed design is considerably higher and comparable to the existing design which has an average efficiency of around 12-15%. 559

As a complement to the studies of industrial engineering,, students have the opportunity of making projects to improve their practical knowledge. In this case a sun tracker was built and controlled using and Arduino microprocessor. The main objective is to build an experimental plant that could be used by the students to practice in control courses. This project has been successfully used in various courses in the educational programs of teaching automatic control.
