On June 3, the opening day of the SNEC International Photovoltaic Power Expo in Shanghai, DMEGC’s booth (6.2H-B160) saw heavy visitor traffic, with its differentiated new products becoming the center of attention. Among them, the steel-frame modules drew particular interest. Compared to traditional aluminum frames, steel frames offer higher mechanical strength, a lower thermal expansion coefficient, reduced carbon emissions, and lower risk of galvanic corrosion. This time, the steel-frame modules feature a new open-frame design that significantly reduces rear-side shading. Combined with cell optimization, this enables a bifaciality rate of over 85%. Additionally, the high-reliability mounting solution supports a maximum wind load of 4,000 Pa.
Right next to the steel-frame modules, the composite-frame modules also attracted a crowd. Made of polyurethane and fiberglass, these frames offer outstanding weather resistance against heat, humidity, acids, alkalis, and salt spray, making them ideal for harsh corrosive environments such as coastal areas. The composite frame has an axial tensile strength approximately five times that of conventional aluminum extrusions, with 100% rebound after elastic deformation. Its thermal expansion coefficient is very close to that of glass, making it an ideal supporting carrier for glass and cells, and helping to withstand long-term environmental stress. This product has already been validated in GW-scale coastal projects.
In the module display area, DMEGC’s previously mass-produced INFINITY RT 3.0 650W module also made an appearance. Featuring high-density packaging technology and an advanced insulation sealing solution, this module delivers comprehensive upgrades in efficiency, high-temperature and high-humidity resistance, and safety. It has passed several industry-leading rigorous reliability tests, including IEC TS 63209-1 and TÜV Rheinland’s 2PFG 2940. Also on display was the next-generation 4.0 ultra-high-efficiency 670W module, which further adopts quarter-cell technology to minimize line losses and achieves an efficiency of up to 24.8%.
For rooftop PV systems, DMEGC showcased lightweight modules. While maintaining strength and reliability, these modules achieve a lightweight design of just 7.5 kg/m²—a 39% weight reduction compared to conventional modules of the same size. This addresses the pain point of insufficient load-bearing capacity in some commercial and industrial rooftops, eliminating the need for costly structural retrofits. Also exhibited was DMEGC’s Greenhouse agrivoltaic rooftop model, which offers various customization options in frame design and module transmittance. The system integrates PV power generation, roof waterproofing, and crop photosynthesis, providing a more convenient and practical solution for the development of green agriculture.
During the exhibition, Kiwa PVEL, a leading权威 PV testing institute, presented DMEGC with the 2026 Top Performer trophy and certificate, once again confirming the company’s leading position in module reliability and technical strength. Global PV media outlet TaiyangNews also awarded DMEGC its annual Top Module award, recognizing the INFINITY RT module’s consistent outstanding performance in mass-production module efficiency rankings over the past year.
