Trina Solar Ltd. has created a new frame design across its full range of 72-cell monocrystalline and 60-cell polycrystalline modules. The frame thickness has been reduced from 40 mm to 35 mm.
According to the company, 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 14.9 kg, down from 15.6 kg, and the 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, Trina adds. Modules with the new thinner frames also 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 was 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.
Modules with the new frames are immediately available, Trina says.
