Integrated PV manufacturer Tongwei has announced that it is collaborating with the World Wide Fund for Nature (WWF) on Arctic conservation and renewable energy development. The partnership aims to enhance the resilience of Arctic ecosystems, aligned with global climate action and biodiversity protection objectives. The joint effort will span multiple areas, including long-term monitoring of ‘multi-year sea ice’ zones, promoting sustainable human-Arctic coexistence practices at the community level, and advancing scientific monitoring and decision-support tools.
Tongwei noted that it has become the first Chinese private enterprise, and the first PV company engaged in long-term climate and energy cooperation, to join WWF’s Arctic protection program.
Last month, MSCI upgraded Tongwei’s ESG rating for 2025 to BBB (see China Solar PV News Snippets).
Float glass manufacturer Shanghai Yaohua Pilkington Glass Group (SYP) has announced plans to upgrade and modify production lines at its 2 facilities in Dalian and Tianjin. The facilities involve a total investment of RMB 404.75 million, of which RMB 300 million will be raised via a private placement. After the upgrades, the lines will produce high-end products such as smart automotive safety glass and TCO-coated glass for perovskite and CdTe thin-film solar cells.
In its fundraising documentation, SYP highlighted the rising demand for thin-film PV in BIPV applications and underscored the essential role of TCO glass in thin-film modules. The company added that the upgraded production lines will enhance the technical performance of TCO glass, enabling better suitability for BIPV and improving alignment with customer requirements.
Last month, SYP announced the completion of the furnace energy-efficiency upgrade and automation renovation of its float glass production line at the Dalian factory (see China Solar PV News Snippets).
The Municipal Housing and Urban–Rural Development Commission of Chongqing City has issued a new policy on renewable energy integration in buildings, setting minimum PV installation requirements for new constructions.
For new residential buildings, accessible rooftops are recommended to allocate over 50% of available area to solar PV or solar thermal systems. Non-accessible rooftops or sloped roofs should target over 80% coverage.
For new public buildings, the combined area for PV or solar thermal systems must account for a minimum of 15% of the building’s applicable area. For specific categories, such as hospitals and schools, the requirement increases to a minimum of 50%.
For new industrial facilities, rooftop PV coverage must be at least 50%.
