Chinese photovoltaic giants are shifting from selling single solar components to providing integrated "solar-plus-storage" system solutions powered by artificial intelligence, driven by grid stability challenges from renewable energy influx. During the 19th International Photovoltaic Power Generation and Smart Energy Conference and Exhibition (SNEC) in Shanghai, companies including Longi Green Energy Technology, Envision Group, and Trina Solar showcased technologies signaling a trend toward solar, storage, and AI integration. Envision Energy launched an AI-driven solar-plus-storage system using weather and energy large language models for real-time forecasting, trading, and grid-forming controls, coordinating wind, solar, storage, and hydrogen assets. Envision said it delivers an integrated smart middle office dynamically coordinating solar string inverters, wind turbines, and its 12.5 megawatt-hours AI energy storage systems. This follows Envision's deployment of a 12.8 gigawatt-hour battery storage cluster in Inner Mongolia, where localized AI agents achieved top-tier trading forecast accuracy and boosted project lifecycle returns by over 20 percent. Longi unveiled its "Longi ONE" full-stack strategy integrating high-efficiency back contact solar technology with a storage framework, enhancing system round-trip efficiency to 93 percent and extending thermal runaway prediction windows to over three months. According to the National Energy Administration, China's total installed solar power capacity reached 1.24 billion kilowatts by the end of March, a 31.3 percent year-on-year expansion.
