When the 19th SNEC International PV Power Generation and Smart Energy Conference & Exhibition wrapped up in Shanghai on June 5, 2026, the most telling detail was not on any product display — it was in the floor plan. For the first time in the expo’s history, battery energy storage systems claimed more hall space than PV modules: six halls versus four. More than 97GWh in publicly announced deals were signed on the show floor before the doors closed.
Storage claims majority of SNEC 2026 floor space for the first time
The shift was hard to miss once you walked through the doors. Six full halls were dedicated to energy storage and four to PV modules—a rebalancing that would have seemed unlikely just a few years ago at an event built around solar. The oversized PV module billboards that once defined the expo’s aesthetic gave way to liquid-cooled BESS units, all-domain energy solution displays, and real-time zero-carbon park simulations running on screens throughout the floor. The visual change made the argument before anyone said a word.
Over 120 leading firms exhibited across both segments, including Sungrow, CATL, Huawei, BYD, Canadian Solar, Hithium, Chint Power, Linyang Energy, and REPT BATTERO. Their displays spanned power conversion systems, residential and commercial storage units, utility-scale BESS, and power solutions designed specifically for AI data centers.
Market economics and AI integration driving storage expansion
Industry participants were direct about what is pushing storage to the front: economic fundamentals, not policy mandates alone. The “duck curve”—the growing gap between excess midday solar generation and peak evening demand—is making long-duration storage less of an option and more of a grid stability requirement.
AI integration ran as a parallel theme throughout much of the exhibition. Huawei Digital Power anchored its presence around a “grid-forming + AI” strategy. Linyang Energy debuted two AI-powered platforms — an O&M Agent and a Virtual Trader 2.0 — designed to shift renewable asset management from manual processes to autonomous decision-making. GoodWe introduced its WE-AI energy operating system, which forecasts electricity prices and load conditions to put residential PV storage into what the company called an “autopilot” mode.
JinkoSolar was explicit about its trajectory, designating 2026 its “breakout year” for storage. Vice president Qian Jing stated that the firm currently holds 5GWh of confirmed storage orders, 5.3GWh of high-potential orders, and over 20GWh in the pipeline, with shipments expected to double year-on-year.
Key product launches: sodium-ion cells, long-duration systems, and higher-efficiency PCS
Several product debuts stood out for their technical specificity. CATL introduced a sodium-ion cell using the same packaging format as its lithium-ion cells, meaning it can be retrofitted directly into existing lithium modules. Already in mass production, the cell has been deployed in a megawatt-scale storage project in Tibet. CATL highlighted sodium’s abundant natural supply and lower cost as advantages for long-duration applications where high energy density is not the primary requirement.
Hithium unveiled the ∞Power 6.9MWh system—described as the world’s first “native” 8-hour long-duration storage solution, built from the ground up for LDES rather than adapted from shorter-duration designs. Product director Ye Zi tied the launch directly to the duck curve problem, describing long-duration storage as “new infrastructure to ensure the safe operation of power systems.”
Huawei Digital Power launched a 430kW string-type grid-forming PCS with a round-trip efficiency of 97.8% and a DC voltage operating range of 550V to 1500V, supporting both lithium-ion and sodium-ion cells. Sungrow introduced its PowerMatrix all-in-one inverter, integrating PV inversion, storage conversion, intelligent energy routing, and grid-forming control into a single device.
More than 97GWh in deals signed on the show floor
Deal activity on the exhibition floor was substantial, with total publicly announced agreements surpassing 97GWh across multiple signings during the event’s run.
EVE Energy led by volume, securing over 67 GWh of bulk storage orders with partners including Shanghai Electric Power Electronics, Jiangsu WETOWN Energy, and Brazil’s Genesis. Ganfeng Lithium followed with over 30 GWh in cooperation intentions spanning utility-scale, commercial and industrial, and residential applications—with partners including Clou, Deye, and GoodWe. CORNEX signed 12GWh in orders, including an 8GWh framework agreement with Dongfang Electric. SVOLT Energy secured 8 GWh with SOFAR Solar, Dahai Group, and Brazil’s BlueSun, while Sav-digitalpower formed a 10 GWh strategic partnership with Hubei EVE Power.
SNEC’s evolving role as a benchmark for the global storage industry
SNEC began as a solar-focused event. The 2026 edition reflects something more structural: energy storage is now a co-equal segment, not a supporting category. The product mix on display—covering utility-scale, commercial and industrial, residential, and AI data center applications—illustrates how broadly the end market for BESS has expanded in a short period.
The volume of on-floor deal signings also points to a shift in how procurement decisions are made. Buyers and suppliers are increasingly using SNEC to finalize agreements rather than simply survey the market, and the 97GWh-plus in signed deals suggests the expo has taken on a transactional function alongside its traditional showcase role.
For anyone tracking the energy transition, the takeaways from SNEC 2026 are straightforward: storage has structurally overtaken PV modules as the dominant physical presence at the industry’s largest annual expo; sodium-ion and long-duration systems are moving from concept to commercial deployment; AI-driven energy management is becoming a standard feature rather than a differentiator; and deal volumes on the show floor indicate that 2026 may mark the year storage economics became self-sustaining.
