Modern inverters don’t just convert power; the ‘brains’ of the solar system have evolved into intelligent, multi-tasking hubs. They are increasingly becoming active participants in grid management, not following the grid, but forming it.
Batteries are equally critical. Solar batteries are key to breaking the glass ceiling that limits further solar growth in advanced solar markets, unlocking their potential to deliver energy not just when the sun shines, but also at different times.
As part of his keynote presentation at the TaiyangNews Inverters & Battery Storage Conference, Hank Zhao, CTO of ESS Europe at CATL, will be speaking on the topic: ‘CATL’s BESS Solution for the European Market.’
Sponsored by JinkoSolar, the Conference will bring top experts together to explore how advanced inverters and battery storage are shaping resilient, future-proof solar energy systems.
The Conference is scheduled for tomorrow, Tuesday, December 16, 2025. Register for free here.
Trinasolar’s National Key Laboratory of Photovoltaic Science and Technology announced that a large-area 210 × 105 mm² perovskite/crystalline silicon tandem solar cell, jointly developed with the Huairou Laboratory, has achieved a record conversion efficiency of 32.6%, as certified by Fraunhofer ISE CalLab. The company claims this result establishes a new world record for tandem cells of this size.
Based on this cell technology, Trinasolar has also integrated a 3.1 m² industrial-standard tandem module, which was certified by TÜV SÜD. The module delivered a power output of 865 W, setting a new power output record.
China’s Ministry of Industry and Information Technology (MIIT) has released the country’s first list of national-level manufacturing pilot test platforms, which is the first nationwide selection of internationally advanced platforms to accelerate the commercialization of major indigenous innovations.
Tongwei’s Advanced Photovoltaic Device Pilot Test Platform is one of 21 platforms selected from more than 2,400 candidates and is said to be the only PV-related platform on the list.
According to Tongwei, the platform is based at the company’s Global Innovation and R&D Center and features a gigawatt-scale heterojunction (HJT) pilot line, the ‘world’s largest’ intelligent module reliability laboratory, and integrated R&D workshops. It focuses on pilot-scale development of high-efficiency crystalline silicon cells, modules, and frontier technologies, covering TOPCon, HJT, THL, BC, and perovskite/crystalline silicon tandem cells and modules.
Recently, Tongwei’s Jintang County manufacturing base passed the PCCC product certification and the Green Product Certification supervision and extension audit conducted by the Power Certification Center (Beijing) (see China Solar PV News Snippets).
Xinjiang has initiated the second round of mechanism-based electricity price bidding, with a total eligible power volume of 19.83 billion kWh.
Of this total, 6.76 billion kWh is allocated to solar projects, including PV and concentrated solar power (CSP), and 13.06 billion kWh for wind power projects. All projects in this round will bid within a price range of RMB 0.15 to RMB 0.262 per kWh, with a 10-year execution period.
In the previous round held in October this year, Xinjiang allocated 3.60 billion kWh of mechanism-based electricity to PV projects at a price of RMB 0.235 per kWh, and 18.50 billion kWh to wind power projects at RMB 0.252 per kWh (see China Solar PV News Snippets).
According to the latest monthly statistical bulletin from China’s National Bureau of Statistics, large-scale industrial enterprises – defined as those with annual main business revenue of RMB 20 million or more – produced 73.49 GW of solar cells in November, down 3% year-on-year but up 5.55 GW from 67.94 GW in October (see China Solar PV News Snippets).
Cumulative solar cell output from January to November reached 760.57 GW, representing a 9.9% year-on-year increase.
The bulletin also showed that China’s total power generation from large-scale industrial enterprises amounted to 8,856.7 billion kWh in the first 11 months, up 2.4% year-on-year. Solar and wind power generation reached 529.1 billion kWh and 949.9 billion kWh, respectively, up 24.9% and 9.6% from the same period last year.
