1. Exhibition Overview: In-depth Perspective of the Global Photovoltaic Industry

From June 11 to 13, 2025, the 18th International Solar Photovoltaic and Smart Energy (Shanghai) Conference and Exhibition (SNEC) was grandly opened at the Shanghai National Convention and Exhibition Center. As one of the largest and most influential industry events in the global photovoltaic field, this exhibition attracted more than 3,600 companies from nearly 100 countries and regions to participate in the exhibition, presenting the latest achievements of the entire industrial chain of the photovoltaic industry from upstream materials, midstream equipment manufacturing to downstream applications, and becoming an important window for insight into the development trend of the global photovoltaic industry.

 

Although the photovoltaic industry is currently in a period of deep adjustment and the market is facing multiple pressures such as overcapacity and price fluctuations, the exhibition site is still hot, especially the booths of leading companies are very popular. Compared with previous exhibitions, this year’s corporate exhibition strategy has changed significantly. Large-scale advertising and eye-catching means of publicity have been significantly reduced. Companies pay more attention to the in-depth display of product technology content, the exchange and discussion of cutting-edge industry technologies, and the conversion of actual orders. This change profoundly reflects the development trend of the industry gradually returning to rationality in the face of difficulties and focusing on core technologies and improving product competitiveness.

III. Industry Trends and Outlook: Rationally Respond to Challenges and Seize Development Opportunities

 

(I) Technological Innovation: The Core Driving Force for Industrial Upgrading

New battery technologies represented by perovskite stacking and BC technology have shown strong development potential at this exhibition. Although they still face many challenges in terms of stability, mass production yield and cost control, with the continuous investment and innovation in technology research and development, they are expected to break through the existing technical bottlenecks in the future and lead the photovoltaic industry into a more efficient era. At the same time, mature technologies such as TOPCon are also being continuously optimized and upgraded to improve performance and reliability, and will continue to occupy an important position in the market for some time to come. In addition, the innovation of inverter and energy storage technology and the intelligent integration of system solutions will further improve the comprehensive utilization efficiency and market competitiveness of photovoltaic energy, and technological innovation will continue to be the core driving force for the upgrading of the photovoltaic industry.

 

(II) Capacity Clearance and Market Reconstruction: The Inevitable Trend of Industry Adjustment

At present, the photovoltaic industry has a prominent problem of overcapacity, and the capacity of polysilicon, components and other links is seriously in excess of demand, resulting in a sharp drop in market prices and increased operating pressure on enterprises. Against this background, capacity clearance has become an inevitable trend in the development of the industry. Leading enterprises actively promote government-enterprise linkage and industry self-discipline, accelerate the withdrawal of inefficient production capacity from the market, and optimize the industrial structure. It is expected that the next year will be a critical period for the supply-side reform of photovoltaics. As production capacity is gradually cleared, the market supply and demand relationship will be improved, and industry competition will shift from pure price competition to competition in technology, brand, service and comprehensive solution capabilities, and the market structure will also be reconstructed. Enterprises with technical advantages, cost advantages, brand influence and good market channels will stand out in future competition and occupy a dominant position in the market.

 

(III) Diversified application scenarios: Expanding the space for industrial development

With the continuous advancement of photovoltaic technology and the continuous reduction of costs, the application scenarios of photovoltaic energy are becoming increasingly diversified. In addition to traditional large-scale ground power stations and distributed photovoltaic projects, the “photovoltaic +” model is constantly innovating, and its integration with agriculture, fisheries, construction, transportation and other fields is becoming increasingly in-depth, giving rise to a variety of new formats such as agricultural photovoltaic complementarity, fishery photovoltaic complementarity, BIPV (photovoltaic building integration), photovoltaic transportation facilities, etc. At the same time, the development of energy storage technology has effectively solved the problems of intermittent and volatility of photovoltaic energy, and promoted the widespread application of photovoltaic storage integration in household, industrial and commercial and large-scale energy projects. The expansion of diversified application scenarios not only opens up new market space for the photovoltaic industry, but also provides more possibilities for achieving energy structure transformation and promoting sustainable development. In the future, with the further expansion and innovation of application scenarios, the photovoltaic industry will play a more important role in the global energy system.
