A standardising for the dimensions of rectangular silicon wafer modules to 2382x1134mm has been reached following a consensus by module manufacturers.

Nine module manufacturers, including Trina Solar, reached the consensus standardising the dimensions on 7 July 2023, with the module based on Trina’s 210R modules that were launched in April 2022.

The nine companies have called for current and future designs for the 210mm series modules to adhere to the specifications for module dimensions and mounting holes outlined by the China Photovoltaic Industry Association.

In April it presented the comprehensive value of its 210R modules at a module-size workshop that the association organised. These advantages include design concepts maximising container utilisation, achieving a rate of 98.5%, increased customer value, manufacturability and proven safety and reliability, with cumulative shipments exceeding 30GW+.

Trina proposed that dimensions of 2384x1134mm be adopted as a universal industry standard, a suggestion that was agreed upon by the association and participating companies.

At this year’s SNEC exhibition in Shanghai, the dimensions of 2384/2380x1134mm were adopted by major module manufacturers in their products. Now, with the other eight companies, Trina will continue to push for an industry standard.

Trina has been at the forefront of the industry, leading standardisation with its Golden Size design concept and products. Trina has thus laid a solid foundation for the standardisation of module dimensions across the entire industry.

Regarding the dimensions of large-format modules, promoted by Trina, in May 2021 the China Photovoltaic Industry Association established industry standards for 60-cell modules with overall dimensions of 2172x1303mm and mounting hole locations based on a 210mm cell as well as for 66-cell modules with overall dimensions of 2384x1303mm.

Wafer technology in 210mm has shown strong advantages, especially Vertex 600W+ modules. Based on its advanced 210 technology, with the integration of n-type technology, Trina leads the industry to embrace 700W+. With this joint initiative, the PV industry takes a step further toward 210mm technology.

Throughout the various stages of development, the trend toward larger formats and higher power output has been a key driver for advancing and upgrading the industry. Behind this progress, standardisation of module dimensions plays a crucial role.

Trina Solar believes that the latest joint initiative represents an end to the historical variation in module sizes, highlighting a clearer trend of 210mm modules with ultra-high power and higher performance which will have significant benefits for the photovoltaic industry globally.
