Solar wafer and module manufacturer HY Solar has rolled out its first HT 3.0 high-efficiency 4-cut module from its Jiangyin facility in Jiangsu Province.
The module integrates HY Solar’s proprietary n-type TOPCon 3.0 cell technology, which the company said has achieved cell efficiency of up to 27.5%.
HY Solar said the 4-cut design, combined with tightly packed cells and high-density, small-gap encapsulation, improves power generation per unit area. The smaller cell structure is also designed to improve reliability by reducing the risk of micro-cracks and limiting the impact of individual cell anomalies on overall output.
The company added that the optimized ‘parallel-series-parallel’ circuit design reduces hot spot risks and enhances performance under high-temperature and shaded conditions.
In March, HY Solar announced that its self-developed slicing equipment produced ultra-thin wafers measuring 40 μm (see China Solar PV News Snippets).
Major energy group Shenergy has issued a tender to procure 1 GW of high-efficiency PV modules for projects planned for 2026-2027.
The tender covers BC and TOPCon modules, with deliveries required within 1 month of contract signing. The framework agreement will remain valid through December 31, 2027, while bid opening is scheduled for May 28, 2026.
In February, Shenergy announced plans to issue up to RMB 2.0 billion in convertible bonds to fund renewable energy projects (see China Solar PV News Snippets).
Integrated solar manufacturer TCL TZE has received TÜV Rheinland’s 2PfG 2926 Anti-Shading Performance ‘A+’ certification for its self-developed multi-split TOPCon modules.
According to TCL TZE, this certification – a first in the industry – evaluates module performance under shading scenarios such as bird droppings, dust accumulation, and structural shadows. Test results showed power loss of -6.4% under single-point shading conditions, compared with -11.7% for conventional half-cut modules.
Under multi-point shading conditions, TCL TZE’s modules recorded a power loss of -19.6%, versus -26.2% for half-cut products. The company said the modules have demonstrated 3% to 6% gains in power generation in actual projects.
On the financial side, in March, TCL TZE reported increasing revenues and a narrowed net loss for FY2025 (see TCL TZE Improves FY2025 Revenues; Narrows Net Loss).
China and Tajikistan have agreed to deepen cooperation in renewable energy, including PV, wind power, energy storage, and related technologies, equipment, and standards.
The agreement was signed during Tajik President Emomali Rahmon’s state visit to China from May 11 to 14, 2026, where he met with President Xi Jinping.
The joint statement also emphasized cooperation under the Belt and Road Initiative framework, covering industry, trade, investment, and communications.
