The testing center of solar module frame manufacturer Yonz Technology’s Research Institute has received accreditation from the China National Accreditation Service for Conformity Assessment (CNAS) under registration number CNAS L23913. With this accreditation, the laboratory has gained the authority to certify the credibility of testing data, which is internationally recognized (covering over 60 economies and 50+ mutual recognition agreements). Test reports issued by CNAS-accredited labs serve as a ‘passport’ for entering global quality systems. Yonz’s accreditation scope covers aluminum alloy composition analysis, mechanical property testing, metallographic inspection, chemical analysis, and salt spray testing.
In April, Yonz started construction on its new 100 GW aluminum frame manufacturing base in Baotou City, Inner Mongolia (see China Solar PV News Snippets).
The Shanghai Municipal Development and Reform Commission has released the competitive allocation results for 2.1 GW of offshore solar PV projects.
The Lingang No. 2 Offshore PV Project (650 MW) will be led by Shenergy
Shanghai Electric Power will lead the Fengxian No. 1 Offshore PV Project Phase II (500 MW), Donghai Bridge No. 2 (164 MW) and Donghai Bridge No. 3 (36 MW) projects
China Datang will head the Donghai Bridge No. 1 Offshore PV Project (199.8 MW)
China Three Gorges will lead the Jinshan No. 1 Offshore PV Project (553.5 MW)
According to the release, electricity prices for these projects were determined through a voluntary bidding process. For projects totaling 1.15 GW, the proportion of mechanism-based electricity eligible for fixed tariffs is capped at 90% of annual generation, while the cap is 70% for the remaining projects.
A metro track solar PV project, invested and developed by a subsidiary of China Railway Construction Corporation (CRCC), has officially commenced construction in Hefei, Anhui Province. The project will have an installed capacity of 21.6 MW and is expected to generate 22.98 GWh of electricity in its first year of operation.
TCL Solar, the module production arm of TCL TZE, is supplying its back contact (BC) solar modules for the project. The company stated that, in addition to high performance, BC modules offer an aesthetically pleasing, busbar-free front design that helps them better integrate into the city’s transportation landscape.
At SNEC 2025 in June, TCL Solar promoted its G12R-66P series double-glass BC module, rated for up to 680 W power and 25.2% efficiency (see TCL Solar’s Upgraded 25%+ Efficiency BC Module At SNEC 2025).
China’s State Administration for Market Regulation (SAMR) has released its first dedicated implementation rules for product carbon footprint label certification, covering 17 product categories, including solar PV modules.
The PV module-specific rules stipulate that certification bodies use GB/T 24067-2024 (Requirements and Guidelines for Quantification of Product Carbon Footprint) and SJ/T 11926-2024 (Product Category Rules for Carbon Footprint of PV Modules) as the basis for certification. Certification will follow a process that includes an initial inspection, verification of the product's carbon footprint, and post-certification supervision. Solar modules will be certified by model specification, with each combination of manufacturer, production site, product type, and specification constituting one certification unit. Any changes in these factors require a separate certification unit.
Earlier this month, SAMR and the Ministry of Industry and Information Technology (MIIT) jointly issued the 2025-2026 Action Plan for Stabilizing Growth in the Electronic Information Manufacturing Industry (see China Solar PV News Snippets).
