Integrated solar PV & ESS manufacturer Trinasolar has signed a technology cooperation agreement with Singapore’s Nanyang Technological University (NTU) to advance AI-based energy storage solutions. The collaboration is being carried out through NTU’s Energy Research Institute (ERI@N) and Centre for Power Electronics (CPE) and focuses on key technologies and applications related to energy storage planning and energy management.
The partnership covers the entire lifecycle of smart energy storage solutions, from initial investment estimation and system design to long-term operation and maintenance. Trinasolar stated that by integrating AI-driven smart energy solutions, the company will work closely with NTU to deliver superior energy storage solutions for global customers.
Recently, the China Green Supply Chain Alliance PV Committee launched the ‘world’s 1st’ fully recycled solar module, an effort led by Trinasolar (see China Solar PV News Snippets).
Integrated solar PV manufacturer Tongwei has commenced construction of a 350 MW wind-solar-storage integrated green electricity silicon production project in Baotou, Inner Mongolia. The project includes a high-purity industrial silicon powder production facility with an annual output of 119,800 tons, along with a by-product output of 168.2 tons of fine industrial silicon powder.
Tongwei has allocated 350 MW of renewable energy capacity to power the project, consisting of 300 MW of wind power and 50 MW of solar power, along with an 80 MW/6-hour molten salt energy storage system. This facility is said to be China’s 1st fully self-consumed wind-solar-storage integrated green silicon project, with a renewable electricity utilization rate exceeding 50%.
Recently, Tongwei Solar's Jintang base photovoltaic testing center received the CNAS Laboratory Accreditation Certificate (see China Solar PV News Snippets).
Solar paste supplier DKEM has released its 2024 annual report, reporting revenues of RMB 15.3 billion ($2.11 billion), a 59.85% year-on-year (YoY) increase. However, its net profit attributable to shareholders declined by 6.66% to RMB 359.96 million ($49.59 million).
DKEM reported solar PV conductive silver paste sales of 2,037.69 tons for the year, up 18.91% from the previous year. Sales of full-set conductive silver paste products for n-type TOPCon cells reached 1,815.53 tons, accounting for 89.10% of the company's total PV silver paste sales.
Looking ahead to 2025, DKEM plans to continue advancing the development and application of low-silver pastes, high-copper pastes, and copper pastes, while actively investing in metallization solutions for HBC and perovskite/crystalline silicon tandem cells. The company also aims to introduce advanced module interconnection and encapsulation materials.
Sharing his views on Day 4 of the 4-day TaiyangNews High Efficiency Solar Technologies 2024 Conference, DKEM’s New Technology Development Director Fangqing Guo said that fine-line printing is one approach to reducing silver costs (see DKEM: N-TBC & HBC Have Highest Future Growth Potential).
20 companies, including Canadian Solar, LONGi, Huasun, Astronergy, DAS Solar, Maxwell, Cybrid, and Autowell, have jointly signed the Initiative on Actively Promoting Independent Innovation and Original Technology Development in the PV and Energy Storage Industry in Suzhou City, Jiangsu Province. Key aspects of the initiative include:
PV and energy storage enterprises should enhance their independent innovation capabilities by increasing R&D investment, encouraging researchers to explore new technological pathways, and embracing risk-taking to cultivate original achievements.
Universities and research institutions should closely collaborate with enterprises, focusing on industry demands to conduct transformative and forward-looking research, thereby providing theoretical support and talent reserves for original technology development.
Industry associations should strengthen communication platforms to facilitate knowledge sharing and technological cooperation, creating a favorable environment for original technology advancement.
Regulatory authorities should enhance protections for independent innovation and original technologies, introduce supportive measures, and promote the healthy and orderly development of the PV industry, fostering a fair and competitive market landscape.
The National Energy Administration (NEA) has released the 2025 Energy Work Guideline, outlining key tasks such as accelerating the development of a new energy system, enhancing energy security, and advancing the green and low-carbon transition, laying the foundation for future energy development.
Some of its key points include:
China’s total installed power generation capacity is set to reach 3.6 TW in 2025, with an annual additional 200 GW of new renewable energy capacity.
The share of non-fossil fuel power generation capacity will increase to 60%.
Accelerated development of large-scale wind and solar bases in desert, Gobi, and wasteland areas, as well as integrated projects combining hydropower, wind, and solar energy, alongside offshore wind power projects.
Expansion of pumped hydro storage capacity to 62 GW.
Optimization of wind and solar power distribution, enhancement of green electricity consumption, and promotion of PV-based desertification control and solar thermal projects.
Support for breakthroughs in smart grid, energy storage, and hydrogen energy technologies, including fuel cells and green hydrogen production.
Strengthened cross-border cooperation on oil and gas, as well as wind, solar, and hydrogen energy projects under the Belt and Road Initiative.
Advancement of international green certificate recognition and encouragement of domestic institutions' participation in global energy standard development.
