# DMEGC Launches Steel-Framed Solar Module Series New bifacial modules utilize zinc-aluminum-magnesium steel frames for enhanced structural durability and efficiency. - **Source:** [pv magazine](https://www.pv-magazine.com) - **Published:** 2026-11-10 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/d688deaa-1709-470e-a8a1-b13b9ae08ee5 ## Innovative Steel Frame Design DMEGC has introduced the Infinity RT 3.0 series, featuring bifacial glass-glass modules with zinc-aluminum-magnesium coated steel frames. This material choice provides nearly double the tensile strength of traditional aluminum alloys. The design aims to improve mechanical reliability while enabling the modules to withstand significant snow and wind loads in utility-scale installations. ## Enhanced Structural Performance The steel frames allow the modules to handle snow loads up to 6,000 Pa and wind loads reaching 5,000 Pa. Furthermore, the material possesses a lower coefficient of thermal expansion than aluminum. This property reduces mechanical stress and minimizes the risk of cell microcracks during extreme temperature fluctuations in outdoor environments. ## Optimized Rear-Side Generation The frame features a unique S-shaped cross-section designed to minimize vertical shading on the module's rear side. This geometry reduces shading by 76% compared to conventional frame designs, increasing the unshaded area by 3.6%. Consequently, the modules achieve a theoretical improvement in bifaciality of approximately 2.8% for higher energy yields. ## Technical Power Specifications The Infinity RT 3.0 series includes six models with power outputs ranging from 640 W to 665 W. These modules utilize 132 n-type monocrystalline half-cut cells and offer efficiencies between 23.7% and 24.6%. Each unit measures 2,382 mm by 1,134 mm and weighs 33.3 kg, featuring 2 mm heat-strengthened glass on both sides. ## Operational Efficiency Metrics The modules achieve a bifaciality factor of up to 85% and operate within a temperature range of -40 C to 85 C. Energy yield simulations suggest an annual generation of 2,078 kWh/kWp. This performance represents a 0.6% increase in generation revenue compared to conventional modules under the same simulated environmental conditions. ## Durability and Corrosion Testing DMEGC subjected the new series to rigorous testing protocols, including salt mist and ammonia corrosion assessments. These tests ensure the modules remain functional in harsh climates. The hardware supports a maximum system voltage of 1,500 V, while maintaining a temperature coefficient of -0.28%/C, ensuring stable performance across diverse global utility-scale deployments. ## Long-Term Warranty Coverage The manufacturer provides a 15-year product warranty alongside a 30-year linear power output guarantee. Degradation is limited to 1% in the first year, with a maximum annual rate of 0.35% thereafter. By the end of the 30-year period, the company guarantees a power output of at least 88.85% for the modules. ## Strategic Market Implications By transitioning from aluminum to specialized steel, DMEGC addresses common mechanical failure points in large-scale solar arrays. This shift highlights a broader industry trend toward material innovation to enhance durability. As utility-scale projects face increasingly volatile weather, such structural improvements become essential for maintaining long-term project viability and financial returns. ## Sources covering this story - https://www.pv-magazine.com/2026/11/10/dmegc-launches-steel-framed-solar-module-series/ — --- _Summary written by Brifing from the original reporting.
