This report presents a detailed technical analysis and design of a grid-connected photovoltaic (PV) system for individual consumption. It encompasses a comprehensive overview of the installation process, including the selection of solar panels (Sharp NU180E1 monocrystalline), their arrangement (18 strings, 216 panels), and the optimal inclination angle. The report addresses the use of array junction boxes, DC and AC isolator switches, string inverters, and LV boards, providing a complete system layout. Data from PVSYST software, including sun path and irradiation data, is incorporated to simulate system performance. The analysis includes an evaluation of voltage generation, solar irradiation, and system efficiency, with data presented in tables and charts. The study compares AC and DC voltage data, and the report provides insights into the efficiency of the system and potential areas for improvement. The report also includes PVSYST simulation results to validate the design and assess the system's performance, with references to relevant sources.
