This project designed a ground-mounted photovoltaic (PV) system combined with energy storage in Kibbutz Mefalsim, located in southern Israel. The system includes approximately 19.5MWp of DC capacity using bifacial panels and advanced inverters. It is aligned with a 15MW AC production license, allowing surplus energy to charge batteries. Energy storage uses AC-coupled LFP battery containers, enabling a four-hour discharge at 50% of the licensed capacity. Simulations and calculations were performed to optimize system layout, panel configuration, and storage capacity. Equipment selection incorporated inverters, transformers, and protection components suited to local grid and site conditions. Final design considerations included voltage drop analysis, fault protection, cable selection, and compliance with Israeli standards. PVsyst simulations evaluated system performance, with inspection procedures to ensure safety and reliability.

The project focused on designing and implementing an electrical system for a high-rise building including three basement floors and 35 residential floors. The power supply is a hybrid system integrating the national electricity grid (Israel Electric Corporation) with photovoltaic (PV) panels to enhance energy efficiency. In its design, the system followed the Electricity Law and its regulations, ensuring compliance with safety and performance standards. The process included a detailed analysis of electrical loads, planning of high-voltage and low-voltage systems, selection of protection measures, and lighting design. Additionally, system resilience to short-circuit currents and related electrical phenomena was assessed to ensure reliability and safety.
