Leading vertically integrated PV manufacturer LONGi and Mingyang Thin Film Technology, a subsidiary of Mingyang Smart Energy, have signed a strategic cooperation and framework agreement covering building-integrated photovoltaics (BIPV) and zero-carbon parks. The cooperation will cover joint project development, solution collaboration, and sharing business opportunities.
Mingyang Thin Film Technology holds engineering qualifications including general contracting for power engineering construction, along with capabilities spanning project investment and development. LONGi will contribute its PV product R&D and system-solution expertise through its BIPV systems business unit. The companies plan to jointly develop projects including zero-carbon parks.
In February, Mingyang announced plans to invest more than RMB 3.5 billion in Zhongshan, Guangdong Province, to develop six clean energy-related projects, including a GW-scale BIPV perovskite production line (see China Solar PV News Snippets).
Perovskite PV manufacturer GCL Perovskite has signed a strategic cooperation agreement with Wuhan Lingyun Building Decoration Engineering Co., Ltd., covering perovskite BIPV curtain walls and PV windows. The partnership will span joint R&D, product supply, EPC contracting, and market development.
GCL Perovskite will provide its GW-scale production capabilities and BIPV product portfolio, while Wuhan Lingyun will contribute its design, manufacturing, and construction capabilities in architectural curtain walls. The companies plan to develop perovskite PV curtain wall and window products for green-building applications, including low-carbon public buildings and ultra-low-energy buildings.
CL Perovskite is leading the drafting of a group standard for single-junction perovskite solar modules for space applications (see China Solar PV News Snippets).
PV wafer-cutting equipment manufacturer and silicon wafer processing service provider Gaoce reported revenue of RMB 1.58 billion in the first half of 2026, up 9.06% year-on-year. However, its net loss widened to RMB 489.89 million from RMB 88.55 million a year earlier, while net loss excluding non-recurring gains and losses increased to RMB 526.38 million from RMB 121.83 million.
Gaoce attributed the wider loss to low utilization rates across the PV supply chain and continued low product prices. In its interim report, the company said mainstream n-type wafers for TOPCon cells are currently about 130 µm thick, while heterojunction (HJT) wafers are typically around 110 µm. It is also conducting R&D and testing on 50 µm ultra-thin wafers for flexible HJT cells.
For FY2025, Gaoce Technology reported revenue of RMB 3.65 billion, down 18.43% year on year (see China Solar PV News Snippets).
The Shandong Provincial Development and Reform Commission, Shandong Energy Administration, and other authorities have issued a notice supporting co-located energy storage at renewable energy plants. For operating and planned PV projects adding storage, the total power rating of co-located storage will be temporarily capped at 50% of the PV plant’s installed capacity, while the limit for wind projects will be 30%.
Lithium-ion battery storage projects must be completed and grid-connected within one year of being included on the project list, while projects using sodium-ion, flow, solid-state, or semi-solid-state batteries will have up to 18 months. Projects adding storage duration without increasing power can be submitted at any time under simplified procedures. The same applies to storage mainly used for auxiliary power and improving output-curve accuracy, provided its power rating does not exceed 5% of the renewable plant’s installed capacity.
Shandong will also support renewable energy plants and co-located storage in jointly participating in the spot electricity market. Where storage is charged using electricity from the associated wind or PV plant, the corresponding discharged electricity will be treated as wind or solar generation for settlement. Existing renewable energy plants that fail to meet their committed storage obligations will face priority output reductions during renewable energy curtailment periods.
