Chinese photovoltaic giants are shifting their business models from selling single solar components to providing integrated “solar-plus-storage” system solutions heavily powered by artificial intelligence, as a massive influx of renewable energy challenges grid stability and drives a pressing need for intelligent, long-duration energy storage.
During the recently held 19th International Photovoltaic Power Generation and Smart Energy Conference and Exhibition, or SNEC, in Shanghai, solar giants including Longi Green Energy Technology, Envision Group and Trina Solar showcased their latest technologies, signaling a definitive industry-wide trend toward seamless solar, storage, and AI integration.
Envision Energy launched its next-generation AI-driven solar-plus-storage system during the exhibition. Powered by advanced weather and energy large language models, the system embeds AI capability into real-time forecasting, trading and grid-forming controls to coordinate wind, solar, storage and hydrogen assets.
Rather than acting as a passive hardware supplier, Envision is delivering an integrated smart middle office that dynamically coordinates solar string inverters, wind turbines, and its massive 12.5 megawatt-hours AI energy storage systems in real time, it said.
This AI-centric approach follows Envision’s landmark deployment of a 12.8 gigawatt-hour battery storage cluster in the Inner Mongolia autonomous region, where localized AI agents have achieved top-tier trading forecast accuracy and boosted project lifecycle returns by over 20 percent.
By merging physical infrastructure with digital intelligence, the company is targeting multi-scenario applications ranging from zero-carbon industrial parks to advanced data centers.
Following a similar philosophy of native consolidation, Longi unveiled its “Longi ONE” full-stack strategy that integrates high-efficiency back contact solar technology with a comprehensive storage framework. The unified architecture enhances system round-trip efficiency to 93 percent and extends thermal runaway prediction windows to over three months, it said.
“Over the past two decades, the PV industry has succeeded in making solar power cheap,” said Li Zhenguo, founder and chief technical officer of Longi. “But as solar takes up a higher share of the generation mix, grid stability, dispatchability and energy storage synergy have become the new structural bottlenecks. Cheap electricity loses its value if it cannot be stably fed into the grid.”
According to data from the National Energy Administration, China’s total installed solar power capacity reached 1.24 billion kilowatts by the end of March, representing a robust 31.3 percent year-on-year expansion.
This unprecedented volume of intermittent green power has triggered a bottleneck in grid flexibility, forcing manufacturers to transition from simple hardware providers to holistic system architects.
Concurrently, the broader market is undergoing a profound transformation. The China Energy Storage Alliance forecasts a massive surge in global cumulative battery energy storage capacity, which is expected to grow by between 8 and 17 times from 2024 to 2035.
The industry, currently dominated by China, the United States and Europe, is transitioning from a period of explosive expansion into a “gear-shifting” phase, said Chen Haisheng, chairman of the CNESA and director of the Institute of Engineering Thermophysics at the Chinese Academy of Sciences.
Between 2026 and 2030, the compound annual growth rate is expected to reach approximately 20.7 percent under conservative estimates and 25.5 percent in ideal scenarios, Chen added.
