Classroom Lighting and Increasing Efficiency With an Energy System Consisting of Different Types of Solar Panels, Batteries and the Grid

Abstract

In the study, three objectives were achieved. The first purpose; To ensure minimum energy consumption in lighting a classroom at Afyon Kocatepe University Dazkırı Vocational School. The illumination levels of ten different points in the classroom and the outside environment were measured. The most ideal illumination level for learning in the classroom was set. For this purpose, algorithm design and implementation were carried out in order to benefit from ambient lighting as much as possible. Second purpose; It is a comparison of the energy production of Monocrystalline, Polycrystalline and Thin film solar panels at the location where the work is carried out. It is to determine the most suitable solar panel type. The final purpose: In the energy production system consisting of Monocrystalline, Polycrystalline, Thin-film solar panels, battery and grid, the best use of the produced energy is ensured by providing energy flow control. Different algorithms have been used to control the energy flow. A control card was designed to implement algorithms. With the designed control card, the current, voltage, and power produced by each of three different PV modules were measured. In addition, the current, voltage, and power used by the lighting system were also measured. PIC18F4550 microcontroller was used to provide USB connection to the computer on the control card. Thus, all data in the system is sent to the computer via a USB port. An interface was designed with C# to evaluate and instantly monitor this data. With the designed interface, all data is displayed instantly and saved to the Access database at 10-second intervals. The system can be controlled manually with the designed interface. When the records in the database were examined, 83% of energy savings were achieved with the lighting algorithm and energy flow control algorithms. With the work done, optimal lighting was provided in the classroom. In this way, many effects that would hinder education, especially visual headaches, are prevented. The effect of training is increased by increasing visual comfort.
