Abstract:

The article focuses on the selection of the components that make up the photovoltaic system; the strategies for its installation; the safe operation and maintenance of the photovoltaic energy system.
The focus of the study is to develop soft skills in PV engineering students to excel in their professional career. These soft skills include clear and effective communication, organizational leadership and quick resolution of emerging conflicts.
Using the potential of engineering to solve the world's most complex problems involves a constant transformation of engineering education, oriented to the formation of skills for designing energy conversion and storage systems, for energy production from renewable energy sources, environmental monitoring.
The efforts of the authors of the article are aimed at forming creative thinking, responsibility, independence, correctness, efficiency, initiative, resistance to stress, motivation and striving for continuous improvement of professional suitability in the future bachelors in photovoltaic technology.
The purpose of the article is for the authors to share their experience of how students studying in the "Photovoltaic Engineering" specialty at the University of Plovdiv - Bulgaria gain knowledge about designing, specifying and modelling the performance of a 28 kW photovoltaic system. They learn to evaluate the effects of shading, module contamination, and snow cover. Most importantly, they form practical skills for installing a 28 kW PV system, which include basic construction, workplace safety, solar assembly and wiring, electrical safety, code compliance, safe commissioning, and system inspection practices.
The engagement of students in the practical work of installing a 28 kW photovoltaic system is expressed in their participation in the layout and placement of solar panels, commissioning and inspection of the solar installation.
The next stage of student engagement is an analysis of the system's power output to see if it meets the manufacturer's specifications and matches energy modelling predictions.
In the article, the methodology for conducting real-time measurements of the quality of the produced electricity is proposed. It assists students in working with advanced supervisory control and data acquisition (SCADA) systems that can be programmed to provide alerts when system performance deviates from expectations. This type of monitoring can detect early indicators of component deterioration, allowing better system maintenance planning and reducing system downtime in the event of necessary repairs.
The results and conclusions for the application of this type of training in photovoltaic engineering show an increase in the students' motivation to learn, as they gain experience in the field of:
- The modelling of a photovoltaic (PV) system for the production of electrical energy 28 kW;
- Photovoltaic (PV) system performance analysis, current-voltage and power-voltage curves for different radiation levels;
- Evaluation of solar resources using Meteonorm software database;
- Carrying out a comparative study of the photovoltaic system, to determine the optimal inter-row distance for each angle of inclination.
- Perform an analysis of the PV system installed at different tilt angles to find the optimal tilt angle for the proposed installation site.
