Astronergy’s ZBB-TOPCon module passes TÜV Rheinland and TÜV Nord testing
Chint Group company Astronergy has announced that its ZBB-TOPCon 78 bifacial module has successfully passed the Level 2 hot spot testing under stringent conditions by TÜV Rheinland and TÜV Nord. The testing was conducted in accordance with the IEC63126-2020 standard. The company said that its module was tested in temperatures above 70°C, as against a 50°C standard hot spot test temperature. After extensive testing, the ZBB-TOPCon 78 module showed no significant appearance changes and a degradation rate of only 0.60%, far below the 5% test standard. Astronergy stated that the zero busbar module, built with its in-house TOPCon 4.0 cell, demonstrated excellent leakage current performance. Additionally, the module’s interconnection between the tabbing ribbon and the cell is further enhanced through a carrier film, ensuring the module's reliability, said the company.
Astronergy displayed its latest TOPCon 4.0 technology-based product offerings for residential and utility applications at the SNEC 2024 event in Shanghai (see Astronergy’s TOPCon 4.0 Module Portfolio On Display At SNEC 2024).
Hunan Energy Investment Group starts construction on 3 GW solar base
Hunan Energy Investment Group has announced the commencement of construction on the 1 GW 1st phase of its 3 GW solar PV composite power generation project. Located in Hongshibao District, Wuzhong City, Ningxia Hui Autonomous Region, the 3 GW project is being built for a total investment of about RMB 12 billion ($1.68 billion), capable of producing 5.9 billion kWh of power annually.
