Trina Solar Limited announced a new frame design across its full range of 72-cell monocrystalline and 60-cell polycrystalline modules. The frame thickness has been reduced from 40mm to 35mm, with products becoming immediately available. The thinner frame profile delivers a 5% reduction in weight, making modules substantially easier to handle and reducing the time needed to complete projects. Trina Solar's 72-cell monocrystalline modules now weigh only 14.9 Kg, down from 15.6 Kg, and 60-cell polycrystalline modules now weigh 18.6 Kg, down from 19.5 Kg. Furthermore, this slimmer profile enables an 18% improvement in shipping container efficiencies, with associated reductions in the carbon footprint and transport costs. Modules with the new thinner frames feature enhanced rigidity and torsional strength. By optimizing the heat treatment process and the aluminum alloy, and introducing an automated corner-key production process, Trina Solar is able to deliver a thinner frame without compromising the mounting flexibility or overall strength of the system. Modules with the new frames meet both IEC and UL requirements for static mechanical load pressure, such as snow loads of 5,400Pa or 550Kg/m(2).
