The CHN Energy Yellow Sea No.1 project, China’s first semi-submersible integrated offshore wind-solar-fishery platform, has been completed. The project is located in Sheyang, Yancheng, Jiangsu Province, within an offshore wind farm area, and was independently developed and built by Longyuan Power, a subsidiary of CHN Energy. It pioneers an integrated model combining wind, photovoltaics, energy storage, and aquaculture.
The platform utilizes an innovative anchoring system, using 4 suction caissons and chains to withstand rough sea conditions, and supports aquaculture in a water volume of 11,500 m³. A 50 kW solar array and modular energy storage system are installed on top of the platform, enabling 100% clean energy self-sufficiency throughout the aquaculture process.
In September, CHN Energy completed the country’s first demonstration project of a ‘grid-generation-storage-railway’ integrated energy supply system (see China Solar PV News Snippets).
China’s National Energy Administration (NEA) has issued the Guidelines on Promoting the Integrated Development of Coal and New Energy Industries. The document calls for leveraging resources in coal mining areas to vigorously develop new energy projects and to implement clean energy substitution in a phased manner. By the end of 2030, China aims to establish a series of clean and low-carbon mining zones.
The guidelines emphasize accelerating the deployment of PV and wind power industries in mining areas, developing large-scale solar bases, and promoting diversified PV+ business models. It supports PV deployment in reclaimed mining zones alongside agriculture, forestry, and livestock farming to enable spatial integration. The policy also encourages floating PV installations on water surfaces formed by mining subsidence and the expansion of integrated PV-aquaculture-crop cultivation applications.
Integrated PV manufacturer JA Solar has signed a strategic cooperation agreement with energy storage producer Cornex. Under the agreement, the 2 companies aim to jointly develop and commercialize key energy storage products, including DC-side systems, outdoor cabinets, and battery units, with a focus on overseas markets. JA Solar stated the partnership aims to establish a robust, efficient, and globally competitive energy storage supply chain that will support JA Solar’s international expansion and strengthen global strategic presence for both companies.
JA Solar recently released its Q3 and 9M 2025 financial results, reporting revenues of RMB 12.90 billion for Q3 2025 (see China Solar PV News Snippets).
Solar tracker manufacturer Arctech reported a steep decline in both revenue and profit during Q3 2025. Previously, the company had reported a 35% year-over-year (YoY) decline in the first half of 2025, but a 20% growth in revenues. During Q3, its revenues plunged 48.54% YoY to RMB 1.34 billion, while adjusted net profit fell 119.5% YoY to RMB 37.47 million.
As a result of weak Q3 results, Arctech’s revenues for the first 9 months of 2025 declined 10.11% YoY to RMB 5.38 billion, with adjusted net profit down 74.78% to RMB 103.26 million.
As of the end of September, the company had total orders worth about RMB 7.20 billion, including RMB 6.01 billion for trackers and RMB 1.11 billion for fixed-tilt structures.
Laser equipment manufacturer Han’s Laser, a major PV laser equipment supplier, reported strong performance growth in Q3 2025, continuing the momentum from H1 2025. The company reported revenues of RMB 5.10 billion, a 35.14% increase over Q3 2024. Adjusted net profit was up 98.47% to RMB 307.33 million, nearly doubling from the same period last year.
For 9M 2025, Han’s Laser recorded revenue of RMB 5.10 billion, representing a 25.51% YoY increase, while adjusted net profit reached RMB 307.33 million, up 51.46% YoY.
