Recently, a number of media platforms have exposed a heavy news, saying that according to reliable channels, the size of the rectangular silicon wafers of photovoltaic modules has been unified. The news pointed out Jinko, Longi, JA, Trina, GCL, Tongwei, Chint, Sunrise, a leading nine photovoltaic companies, said that after full discussion and voting, the nine agreed on the standard size of 72 or 66 pieces of the medium version of the module is 2382*1134.
After multiple verification, the reporter did have this news, or officially announced in recent days. This news can be described as breaking the stone, the 182 and 210 camps sit together for the first time, to reach an agreement on size standardization! Calls and movements for uniform sizes have been around for a long time; After unification, it will greatly benefit the industry and reduce the burden of the industrial chain.
These news also mentioned that the 9 do not unify the rectangular component size, the mounting hole, but also set a regular communication and coordination mechanism, if true, the photovoltaic industry will usher in unprecedented harmony and unity! In May 2021, the China Photovoltaic Industry Association organized an online meeting to discuss the dimensions and installation hole technical specifications of photovoltaic modules, and the component dimensions and installation hole positions of 210mm batteries have been agreed to form a group standard.
In September 2021, Jinko Energy, JA Technology, and Longi Green Energy jointly announced that they would unify the 182 component size and installation hole spacing standards. Regarding the size of the rectangular silicon wafer components focused by the nine companies, it is also possible to go back to April last year, when Trina Solar launched the innovative silicon wafer product “210R”, opening the door of rectangular silicon wafer innovation in the whole industry. Since then, seeing the value of rectangles, many manufacturers have followed up, but each size is different. For example, the rectangular silicon wafer of Longi Green Energy uses the 183.75*182mm specification, Jinko Energy uses 186.8*182mm, JA Technology uses 185*182mm specification, and 192*182mm, which can be described as a mountain. However, the size of the chaos will bring cost increases, first of all, let the upstream production overwhelmed, including raw material procurement, inventory management, capacity planning, equipment automation rate, so that the overall supply chain management and downstream applications are messy and tired. Seeing this mess, Trina Solar first took the lead in fully disclosing 210R product solutions and industrialization feasibility paths to the industry in March this year. Based on product design, power maximization, container loading rate and other dimensions, TRW first proposed the standardization of silicon battery module size, proposed 2384*1134mm the optimal rectangular size, but also by the association, design institute, as well as silicon, batteries, components, equipment and other industrial chain of all links unanimously recognized. Combined with the above news, the size of the nine rectangular silicon wafers is unified to 2382mm, which is only 2mm different from the 2384mm proposed by TRW before, completely within the tolerance range. Through the disclosure of this technology and the sharing of product parameters, Trina Solar has substantially promoted the industry enterprises to achieve the unification of the long side size of the medium-type rectangular silicon wafer components to 2384mm or similar sizes with practical actions. Industry-wide agreement is finally on the horizon. In the medium type rectangular silicon wafer assembly, the uniform size has become the norm. In the small version and large version size, combined with the comprehensive sharing of Trina Solar’s “golden size” design concept recently, and Jinko and JA have followed up the launch of the small board type 1762mm, and the large size 210mm has long been unified, which shows that industry enterprises also show a comprehensive unified trend in the small version and large version size. No matter how tortuous the process, the result is good. Once unified, it will benefit the entire industrial chain. The uniform size will improve production efficiency, reduce manufacturing costs, bring large-scale development, fully release industrial value, and also help optimize the industrial chain supporting, form a mature ecology, reduce the cost of electricity, and promote the maximum value of the application side.
This decision has major implications for the photovoltaic industry and manufacturers of solar mounting systems. Before this agreement, different companies used different sizes and dimensions of solar panels, causing compatibility issues. Manufacturers must design and produce different mounting systems to accommodate different panel sizes, leading to increased costs, inefficiencies and reduced scalability of solar projects.
Impact on Solar Mounting Systems
The unified standard size of rectangular silicon wafers solves the compatibility problem of different photovoltaic modules. Manufacturers of solar mounting systems can now develop standardized solutions compatible with panels produced by the nine leading PV companies mentioned above. This standardized approach brings several advantages.
1. Cost-effective manufacturing: With uniform panel sizes, solar mounting system manufacturers can simplify their production processes and achieve economies of scale. Standardized component sizes allow for mass production and bulk procurement, reducing overall manufacturing costs. These savings can benefit consumers and make solar power more accessible and economically competitive.
2. Improve installation efficiency: The standardized size simplifies the installation process of the solar mounting rack. Installers no longer need to customize the system for different panel sizes, as the same design can be applied to all panels adhering to the unified standard. This simplifies the installation process, reduces labor requirements, and reduces project time.
3. Improved quality and durability: Standardization facilitates the development of robust and reliable solar mounting systems. Manufacturers can focus on improving the strength, structural integrity and overall quality of the system because they no longer have to accommodate various panel sizes. This promises a safer, more reliable installation, ensuring long-term performance and customer satisfaction.
4. Accelerated expansion of solar energy projects: Unified standard scale is conducive to the scalability of solar energy projects. Manufacturers can now produce more standardized panels, speeding up the installation and commissioning of solar farms. This standardization will lead to an increase in installed solar power generation capacity, supporting a larger transition to clean and renewable energy.
The agreement between leading photovoltaic companies to establish a uniform standard size for rectangular silicon wafers for photovoltaic modules is a major milestone for the solar industry. This decision will have wide-ranging benefits, including reduced manufacturing costs, improved installation efficiency, improved quality and accelerated expansion of solar projects. The unification of panel size will not only simplify the design and installation process of solar panel bracket, but also help to promote the adoption of solar energy globally. As we move forward, let us look to a future where renewable energy becomes a mainstream source of electricity, mitigating climate change and ensuring a sustainable future for future generations.
