This project focused on designing a high-voltage electricity generation system for a facility at Moshav Sde Zvi in the northern Negev, utilizing solar panels to produce energy and conserve conventional resources. The goal was to develop a ground-mounted photovoltaic system generating 10 MVA/13MWp, which involved incorporating collectors, inverters, and transformers, with high-voltage and low-voltage rooms. The system converts low DC voltage from solar panels to AC via inverters, using DC collection boards (DCCBs) to optimize efficiency. Energy is then transformed to high voltage through transformers and switchgear per Israeli regulations. The final step was connecting this system to the Israel Electric Corporation (IEC) grid. Our project thus included site planning, safety compliance, component calculations, protection design, and system testing to ensure reliable, cost-effective operation with maximum power output.

The “Dganit Ein Bar” bread factory, founded in 1952, today spans 15,000 m2 and produces approximately 100 tons of baked goods daily. This project focused on designing a modern electrical system that meets the factory’s production, cooling, and storage demands. Key loads include ovens, mixers, and cooling systems, requiring careful load distribution for system reliability. The design includes energy-efficient LED lighting suited to various work areas, emergency lighting, and backup generators for operational continuity during power outages. The system complies with Israeli and international standards, improves energy efficiency, and allows flexibility for future expansions. Ensuring safety, reliability, and sustainability was crucial to this electrical system design project.
