High-Strength Steel Frame Modules | Lower Costs, Higher Efficiency, Safer and More Profitable PV Systems

In recent years, the increasing frequency of extreme weather events such as typhoons and snowstorms has placed greater demands on the safety, stability, and performance of photovoltaic power plants. Distributed PV systems in coastal and high-wind areas often face challenges from strong winds. To address these conditions, ZNSHINE Solar has leveraged years of technical expertise to launch its high-strength steel frame PV modules. With the adoption of new materials and optimized structural designs, these modules perform exceptionally well under high-load environments, significantly enhancing the safety of PV systems. At the same time, they lower system costs and deliver more reliable, high-value solutions to the global market.

^{Reduced Costs, Enhanced Returns}

The introduction of high-strength steel frame modules delivers notable reductions in both material and installation costs while maintaining superior structural strength and weather resistance, ensuring long-term stable operation. These modules utilize S550GD zinc-aluminum-magnesium coated steel, known for its excellent mechanical properties and corrosion resistance, providing high system stability. Benefiting from the raw material cost advantage, these modules offer greater overall cost competitiveness.

In addition, ZNSHINE Solar has optimized the installation method with a flexible clamp structure, simplifying the installation process and significantly improving construction efficiency. This not only reduces initial investment costs but also increases the overall profitability of PV power plants.

During installation, the modules feature a pre-installed nut design, enabling workers to lock components using single-handed power tools. This reduces operational complexity, shortens installation time, and lowers labor costs. Compared to conventional module installation methods, the high-strength steel frame module offers easier, more stable deployment, greatly improving project yield. Thanks to the frame’s exceptional corrosion resistance and structural strength, long-term operation and maintenance requirements are also minimized, further enhancing the lifecycle return on investment for PV plants.

^{Enhanced System Safety}

In terms of safety, the structural strength and durability of the high-strength steel frame module have been comprehensively upgraded to ensure stable operation under extreme weather conditions. Compared with conventional modules, the frame boasts a yield strength of up to 550 N/mm² and a tensile strength of 670 N/mm², representing performance increases of 229% and 258%, respectively. This remarkable improvement equips the modules with significantly higher wind pressure resistance and structural stability. Under challenging weather scenarios such as strong winds, heavy snow, and high loads, the high-strength steel frame can effectively withstand external impact forces, prevent damage, and reduce economic losses from natural disasters—providing investors with solid and reliable protection.

Additionally, the frame adopts a zinc-aluminum-magnesium coating process, delivering outstanding corrosion resistance. In long-term PV system operation, modules must endure conditions such as sand, wind, and salt spray. ZNSHINE Solar’s high-strength steel frame modules have passed 5,000-hour neutral salt spray tests and continue to exhibit excellent protective performance. Their enhanced weather resistance ensures 30 years of rust-free operation in outdoor environments. This advantage makes them especially suitable for offshore PV, coastal power plants, and high-humidity, high-salinity regions—helping investors build more stable and reliable energy assets.

As the global energy transition accelerates, the PV industry is moving toward a future of greater efficiency, safety, and sustainability. ZNSHINE Solar remains attuned to market demands, continuously driving photovoltaic innovation and striving to deliver more efficient and reliable solar solutions. The launch of the high-strength steel frame module, with its outstanding economic and safety benefits, not only optimizes the investment returns of PV plants but also offers the industry a sturdier and longer-lasting component option. Looking ahead, ZNSHINE Solar will continue focusing on product upgrades, supporting the development of global clean energy with superior quality—and making green power more accessible around the world.
