Today marked the beginning of the practical phase of the course, where engineers provided a detailed explanation on how to connect solar energy systems and determine the appropriate number of solar panels according to the electrical load capacity and the type of system being used. They also discussed the function of inverters and their role in converting energy from direct current (DC) to alternating current (AC), along with an explanation of the different types of inverters and their applications in residential, commercial, and hybrid systems. The practical session also included hands-on applications on real solar system models, where participants conducted initial design calculations and learned the steps of safe interconnection between panels, batteries, and inverters, in addition to analyzing system performance and interpreting technical results. Participants expressed great enthusiasm for benefiting from the practical training, which allowed them to combine theoretical knowledge with real-world application, thus enhancing their technical skills in designing and implementing solar energy projects. This activity comes as part of the Solar Energy Hackathon competition organized by the center, which aims to prepare a generation of qualified individuals capable of creating sustainable solutions in the field of renewable energy, supporting the shift towards clean energy in line with the Sustainable Development Goals (SDGs).
