150 MW Utility-Scale Solar Mounting Structures in Israel: Desert Wind Resilience and Zinc-Aluminum-Magnesium Durability

Set across the rocky terrain of the Negev Desert, this 150 MW utility-scale solar facility supplies clean electricity to Israel's national transmission network. Building expansive photovoltaic tracker and fixed-tilt arrays across arid desert topography introduces challenging structural constraints. Plant asset managers and EPC contractors focus heavily on long-term mechanical reliability and cost containment. They face three recurring field challenges: resisting high seasonal desert wind shears and thermal uplift without structural deformation, preventing underground galvanic soil corrosion and airborne sand abrasion over a thirty-year operating life, and avoiding installation delays across vast, uneven ground. Shijie Heavy Industry addressed these engineering demands by delivering a robust cold-formed steel mounting system. We utilized high-strength structural steel profiles coated with a specialized zinc-aluminum-magnesium alloy, providing self-healing corrosion resistance superior to standard galvanizing. Rammed C-channel posts were engineered with variable embedment depths to achieve solid mechanical anchoring in stony desert soils without concrete foundations. High-precision factory punching enabled rapid field bolting across miles of continuous tables. Completing mounting deliveries 30 days ahead of schedule allowed electrical installation teams to string modules smoothly.
