As the implementation of China’s “Three-North PV Sand Control Plan” accelerates toward its 253 GW goal, vast stretches of desert and arid land are being transformed into energy hubs. However, these regions present extreme challenges, including high winds, intense sandstorms and dramatic temperature shifts, all of which test the structural resilience of solar infrastructure. With the industry also facing growing pressure to decarbonize across the full value chain, DAS Solar has launched a high-strength steel frame module, designed to deliver exceptional environmental and economic value by combining superior mechanical strength with circular, low-carbon manufacturing.
As the structural backbone of a module, the frame material has a significant impact on the product’s carbon footprint. Unlike conventional aluminium frames, DAS’ steel frame solution redefines sustainability starting at the source, studies showing that steel frames produce 80% less carbon emissions per unit compared to aluminium during manufacturing. This crucial upstream decision enables the company to embed sustainability into the DNA of its products, with the steel frames treated with an environmentally friendly zinc-aluminium-magnesium alloy coating throughout the manufacturing process, reducing energy use and improving weather resistance. Once the module reaches its end of life, the steel frame is 100% recyclable and can re-enter production loops without any loss in performance.
Within the structural protection offered by the steel frame system, the synergy between solar generation and environmental restoration becomes possible. Electricity generated onsite powers smart irrigation and environmental monitoring systems, enabling the restoration of drought-tolerant vegetation.
This dual capability of low-carbon performance and ecological restoration translates into tangible business value. Projects equipped with DAS Solar steel frame modules gain advantages across financing, permitting and long-term environmental credibility. The fully recyclable structure and strong environmental profile enhance appeal to ESG-conscious investors, while the ecosystem co-benefits strengthen community and policy support.
