The "Super Event" of the global photovoltaic industry—SNEC PV&ES 19th International Solar Photovoltaic and Smart Energy & Energy Storage and Battery Technology and Equipment Exhibition—will be held from June 3 to 5, 2026, at the National Exhibition and Convention Center (Shanghai). According to official introductions, the exhibition covers all segments of the photovoltaic industry chain, including photovoltaic production equipment, materials, cells, modules, photovoltaic engineering systems, energy storage, and mobile energy. It serves as a crucial window for observing trends in photovoltaic manufacturing and smart energy equipment.

As the photovoltaic industry shifts from simple capacity expansion to efficient, low-carbon, and intelligent manufacturing, the application scenarios for photovoltaic pumps are continuously expanding. From silicon material production, slicing and cleaning, cell texturing, acid-alkaline etching, and wastewater treatment, to electronic chemical delivery, cooling circulation, and energy storage thermal management, pumps have become indispensable fluid transport equipment in photovoltaic manufacturing systems. Particularly in systems involving high-purity chemicals, highly corrosive media, high-salinity wastewater, and ultra-clean circulation, the stability of pumps directly impacts product yield, environmental compliance, and continuous production capacity.

The future development trends for photovoltaic pumps begin with corrosion resistance and cleanliness. In processes such as texturing, cleaning, and etching, media like hydrofluoric acid, hydrochloric acid, nitric acid, sodium hydroxide, and hydrogen peroxide are commonly involved. Pump body materials need to upgrade toward lined fluoroplastics, PVDF, PFA, PTFE, silicon carbide ceramics, and high-purity plastics to reduce metal ion precipitation and media contamination. Next is leak-free design. For highly corrosive, toxic, or high-purity media, magnetic pumps, canned motor pumps, and double mechanical seal pumps will become important choices to reduce leakage risks and maintenance costs.

The third trend is energy efficiency and intelligence. Photovoltaic factory production lines operate continuously, with a large number of pumps for cooling water, circulating water, wastewater lifting, and chemical liquid circulation running for extended periods, making their energy consumption a non-negligible factor. New products should be equipped with efficient hydraulic models, variable-frequency motors, and online monitoring interfaces to enable real-time monitoring of flow, pressure, temperature, vibration, current, and leakage status, meeting the demands of smart factories and predictive maintenance. Companies like Huawei also emphasized at SNEC 2026 that the photovoltaic and energy storage industry is entering a phase of digitalization, intelligence, and full-scenario solutions, placing higher intelligence requirements on supporting pump equipment.

Therefore, the design direction for new photovoltaic pump products should focus on: high purity and cleanliness, strong corrosion resistance, leak-free operation, low particle precipitation, energy-saving variable frequency, modular maintenance, and intelligent monitoring. For pump manufacturers, it is no longer sufficient to provide single pumps. Instead, they must form systematic solutions—including cleaning pumps, chemical liquid pumps, wastewater pumps, cooling circulation pumps, ultra-clean pumps, and energy storage thermal management pumps—tailored to different sections of the photovoltaic production line. Only then can they better meet the high-quality development needs of the photovoltaic and smart energy industry.
