DAS Solar, a China-based PV module manufacturer, has unveiled high-strength steel-framed modules designed for harsh desert conditions as the “Three-North PV Sand Control Plan” neared its 253 GW goal. DAS said the steel structure was chosen to reduce upstream emissions while enhancing the life-cycle durability of large-scale installations. DAS Solar stated that steel frames with zinc-aluminum-magnesium coatings are desined to improve corrosion resistance, withstand sandstorms and maintain structural integrity under dramatic temperature conditions. DAS Solaradded that the fully recyclable design supported circular material flows, while stronger physical performance allowed arrays to stabilize soil, slow erosion and create favorable micro-climates in arid regions. DAS Solar added that these features strengthen long-term project value by improving technical resilience and environmental suitability.
