The 2025 Shanghai Photovoltaic Exhibition (also known as the 18th SNEC International Solar Photovoltaic and Smart Energy Exhibition), as a grand event in the global photovoltaic industry, has attracted numerous enterprises to showcase cutting-edge technologies and innovative products. The following are the core highlights and industry trend analyses of this exhibition:

1.The exhibition profiles 

Time and Place: June 11th to 13th, 2025, National Exhibition Center (Shanghai).

Scale and Participation: Over 3,500 companies participated, with nearly 400,000 square meters of exhibition space. The proportion of international exhibitors reached 30%. It is estimated that the number of visitors will exceed 500,000.

Industry Position: As one of the most influential photovoltaic exhibitions in the world, SNEC has become an important platform for enterprises to showcase their technical capabilities and expand their markets.

2.Core technology and product display

(1) Efficient Photovoltaic Cell Technology

Competition between TOPCon and BC Technologies: Companies such as Jinko Energy and Zhengtai New Energy showcased TOPCon battery modules, such as Jinko's TigerNeo 3.0 series (power 670W, conversion efficiency 24.8%); while companies like Aixue Co., Ltd. and Longi Green Energy launched BC technology products, such as Longi's Hi-MO 9 modules (battery efficiency 27%, module power 670W).

Breakthrough in Perovskite Technology: Suntech Technology exhibited perovskite single-junction modules (conversion efficiency 19.04%) and tandem modules (26.36%), and launched the world's first GW-level large-sized perovskite tandem module production base.

(2) Smart Energy and Energy Storage Systems

AI Empowering Energy Management: Heng Intelligent launched the PANGU 3.0 smart energy management platform, supporting monitoring of up to 100,000 points, and integrating SaaS services such as virtual power plants; Trina Solar showcased the GainCube AI smart operation solution, increasing photovoltaic and energy storage benefits by 5%-10%.

Diversification of Energy Storage Technologies: Companies showcased technologies such as compressed air energy storage, pumped hydro energy storage, and flywheel energy storage, as well as EPC engineering solutions for energy storage stations.

(3) Expansion of Photovoltaic Application Scenarios

Building-Powered Integrated Photovoltaic (BIPV): Longi Green Energy launched Hi ROOF S building products, suitable for various roof tile types, promoting the integration of photovoltaic with buildings.

Industrial and Commercial Green Energy Solutions: JA Solar showcased energy solutions for industrial and commercial sectors, such as photovoltaic+, charging piles, and zero-carbon parks.

3.Industry trends and challenges

(1) Diversification of technical routes

Although the TOPCon and BC technologies are in fierce competition, the industry is gradually calling for the end of the debate and moving towards next-generation technologies such as perovskite tandem cells. Companies like Trina Solar and Xinxin Group have set up pilot production lines for perovskite, and the efficiency has significantly improved.

(2) Enterprise transformation and business diversification

Photovoltaic enterprises are actively expanding new businesses such as energy storage and hydrogen energy, and exploring new application scenarios such as building-integrated photovoltaics to cope with industry fluctuations. For example, Xinxin Technology has expanded its second growth curve by selling silane gas.

(3) Opportunities in the industry downturn

Although the photovoltaic industry suffered losses in 2024 and the first quarter of 2025, the exhibition enthusiasm remained high, and enterprises sought breakthroughs through technological innovation and market expansion.
