I. The Big Picture: A Paradigm Shift, Not a Cyclical Swing

The central signal coming from the solar and storage industry right now is not that "storage is hot." It is that the entire competitive logic of the new energy sector has undergone a fundamental shift.
Over the past two decades, solar won on scale and cost reduction , driving the levelized cost of electricity from several yuan per watt down to fractions of a cent, making clean power cheaper than coal. That mission is complete. The question for the next phase has changed: how do you make cheap electricity dispatchable, manageable, and capable of supporting an increasingly complex modern grid?
The answer is the combination of solar-storage integration, grid-forming technology, and AI-driven dispatch , in other words, system capability, not the optimization of any single product's specifications.
The fact that storage has now eclipsed solar in industry visibility is not a coincidence. It is a direct reflection of a fundamental restructuring of the industry's underlying logic. Solar companies collectively "embracing" storage is not some grand industrial vision , it is simple survival arithmetic. In 2025, 15 major Chinese solar supply-chain companies recorded combined net losses exceeding RMB 56 billion, while Sungrow's storage business generated RMB 37.2 billion in revenue, and Canadian Solar's storage systems carried a gross margin of 28.6%. Storage margins, are still positive.
But the logic of solar-storage integration goes beyond profitability. The higher the share of solar generation, the greater the pressure on grid stability. LONGi founder Li Zhenguo put it plainly: "Cheap electricity has a ceiling on its value if it cannot be reliably fed into the grid and used flexibly." Storage is no longer an optional add-on , it is a hard requirement for the power system.
GCL Group chairman Zhu Gongshan recently declared: "The old development paradigm and industry narrative have completely broken down." The first half of the solar story was AI plus energy; the second half is space energy. The starting gun for the next phase has already been fired.

II. New Application Technologies: Six Directions Worth Watching

1. Grid-Forming Technology , From "Following the Grid" to "Building the Grid"

This is the most important technical keyword in the industry right now , not a marketing claim, but a hard system requirement for grids with high penetrations of renewable energy.
Traditional inverters and storage systems are "grid-following" , they do whatever the grid tells them to. But once the share of renewables exceeds a certain threshold, the grid itself becomes unstable, and grid-following systems have nothing to follow.
Grid-forming technology enables power electronics to behave like synchronous generators: voltage and frequency support, inertia emulation, primary frequency response, black-start capability, and weak-grid operation. Sungrow's PowerMatrix inverter gives every solar-storage generation unit the external characteristics of a synchronous machine. Huawei's string-type grid-forming storage system achieves stable grid formation at the plant level, across all operating conditions and time domains, with a round-trip efficiency of 97.8% , a new industry benchmark. CRRC Times Electric's Yunqu 2.0 grid-forming PCS has a reactive power start-up time under 5 ms.
The inverter is evolving from a power conversion device into an energy control node within the new power system.

2. AI-Data Center Power Coordination (AIDC) , Storage's Newest Demand Driver

"AI-data center power coordination" has become one of the most frequently discussed concepts in the industry. The reason: GPU clusters in data centers experience millisecond-level power fluctuations, placing extreme demands on supply-side stability and response speed , comparable, as one industry insider put it, to "caring for a cardiac patient."
The combination of solar, storage, and power electronics is well positioned to meet that demand: millisecond-level dynamic response, grid-forming capability, and high efficiency. Huawei has extended its grid-forming capability to AI data center loads; Sungrow (上能电气) has launched a full-scenario AIDC solution; JinkoSolar has introduced its "Starcloud No. 1" 680W module designed specifically for AIDC applications. Conservative estimates put the new solar capacity driven by data centers at 85–100 GW between 2025 and 2030.
AI is not only pulling storage demand from the consumption side , it is fundamentally restructuring how storage systems are operated.

3. AI-Native Energy Dispatch , From Monitoring Dashboards to Energy Agents

The "digital platforms" of the past were essentially monitoring systems with dashboards. The real change now is that AI is moving from "seeing the system" to "understanding the system" and "operating the system": generation forecasting, battery state-of-health assessment, charge/discharge strategy optimization, spot market trading decisions, and autonomous operations and maintenance.
Envision Energy has launched what it calls the world's first AI-native solar-storage integrated system, driven by dual AI models , "Tianji" for meteorological forecasting and "Tianshu" for energy management. Solis (三晶) is accelerating AI capability development; the industry widely expects AI capability to become the primary criterion by which customers select products in the next cycle.
The future core competency of an energy system is not hardware efficiency but software dispatch capability. Those who can connect solar forecasting, storage control, load management, and power market trading into a single coherent platform are best positioned to move from "selling equipment" to "selling energy services."

4. Native Solar-Storage Integration (DC-Coupled Architecture)

True solar-storage integration is not about putting solar panels and battery cabinets in the same project, nor is it a physical assembly of "modules + inverter + battery enclosure." It is the coordination of generation forecasting, battery state, inverter control, grid constraints, and electricity price signals.
LONGi's LONGi ONE strategy has been brought to market as an integrated solar-storage solution: native integration from BC solar cell technology through the full 5S storage system stack (BMS, iCCS, EMS, TMS, PCS), achieving a round-trip system efficiency of 93% and improving project IRR by 2–4 percentage points. (Stitched-together solar-storage systems typically underperform their nameplate efficiency by more than 4 percentage points.) Infineon Source's all-liquid-cooled solar-storage-charging integration solution puts solar, storage, and EV chargers on a shared DC bus, improving overall system efficiency by 2–5%.

5. Long-Duration Storage (8 Hours and Beyond)

As the "duck curve" deepens , solar flooding midday grids and pushing prices to zero, while evenings see price spikes with no solar supply , long-duration storage is becoming essential infrastructure for grid security.
Hithium has launched what it describes as the world's first native 8-hour long-duration storage solution: 6.9 MWh in a 20-foot container, using 1,300 Ah cells, with a design life of 25 years. The primary technical challenges are the exponential increase in thermal management difficulty and the extended safety validation cycles for large-format cells.

6. V2G and Distributed Storage Networks

Infineon Source began developing V2G technology in 2015 and has now brought a mature solution to market: converting the battery capacity of millions of electric vehicles into distributed storage resources, offering a complete package of standardized core modules, intelligent operations platforms, and electricity trading strategies. This is one of the most structurally significant long-term directions in the storage industry.

III. Materials and Technology: The Efficiency Ceiling and Next-Generation Pathways

Perovskite Tandems , Efficiency Breaks 30%, Space Applications Lead Commercialization

Perovskite technology has seen a wave of recent milestones. GCL's 2,042 cm² large-area perovskite-silicon tandem module achieved a certified efficiency of 30.23% , breaking the 30% barrier for the first time. JinkoSolar's perovskite/TOPCon tandem cell set a new world record for the 33rd time, reaching a certified efficiency of 34.82%. Across the industry, 12 manufacturers have now launched 18 perovskite products.
Notably, the space solar market is emerging as the first viable commercial pathway for perovskite technology. Space applications require light weight, radiation resistance, and high efficiency , precisely the core advantages of perovskite. The space market also features small production volumes, high added value, and relatively high cost tolerance, making it an attractive high-value niche for perovskite before large-scale terrestrial commercialization matures. The primary remaining obstacles for ground-level scale-up are: stability, moisture/oxygen encapsulation, and yield at larger cell areas.

Space Solar , From Concept to Real On-Orbit Validation

In 2026, space solar has moved from concept to genuine industrial deployment:
· GCL has signed a strategic on-orbit testing agreement with Ziwei Technology, with a perovskite cell space-flight experiment planned for within 2026
· Junda's flexible heterojunction crystalline silicon cells have entered orbit aboard the "Youxi" satellite (launched by the Lijian-1 rocket) for in-orbit validation under extreme environmental conditions
· JA Solar has launched a "Space Energy Technology Ecosystem Alliance," with product specifications of 60-micron ultra-thin silicon + perovskite tandem at a power-to-weight ratio exceeding 2 W/g
GCL's Zhu Gongshan estimates the commercial horizon at five to ten years. Within that window, the synergy between China's commercial space sector and its solar industry could establish a meaningful first-mover advantage.

BC / xBC Technology , Representing the Efficiency Ceiling

Fifteen manufacturers have now introduced xBC modules. Aiko Solar's ABC cells reach a peak efficiency of 26%, with targets of 30% by 2030 and 35% by 2035. Gaojing Solar has become the third company to achieve BC module mass production. BC technology represents the direction of the efficiency ceiling for ground-based solar, but key patents remain concentrated in a small number of holders, cost gaps with TOPCon persist, and market adoption is still building.

Sodium-Ion Batteries , Economics Under Pressure, Awaiting a Truly Compelling Use Case

CATL has launched a "one housing, dual chemistry" sodium-lithium compatible platform; Rept Battero has introduced a 320 Ah sodium-ion cell with a cycle life exceeding 20,000 cycles. However, lithium carbonate prices have fallen from a peak of RMB 600,000/tonne to below RMB 200,000, substantially eroding the cost advantage of sodium's "no lithium" proposition. The sodium-ion supply chain remains far less mature than lithium-ion, and reaching energy density parity with LFP is still described as a "three-year" horizon. Sodium-ion has a future , but it needs a genuinely compelling application where it is the only viable option to prove itself.

Silver Reduction and Application-Specific BOS Materials

Rising prices for silver, copper, and aluminum are pushing the industry toward "reduced-silver" and "silver-free" cell architectures. Module balance-of-system components are differentiating rapidly: anti-soiling surfaces, anti-glare coatings, hail resistance, lightweight and flexible designs, BIPV integration. Modules are no longer standardized panels , they are being redefined around specific application requirements.

IV. Market Dynamics: Structural Changes at the Micro Level

Hybrid inverters disrupting the C&I storage PCS market. At least 15 companies have recently introduced hybrid inverter products above 125 kW. Hybrid inverter solutions offer clear advantages in commercial and industrial storage applications , eliminating intermediate conversion stages and reducing system losses , and are displacing traditional distributed modular PCS architectures in what amounts to a structural redefinition of the product category.
The C&I storage price war approaching its end game. Six hundred companies are competing, with PCS average selling prices compressed to RMB 0.10/W and some bids as low as RMB 0.06/W, even as component and copper costs have risen approximately 10%. Fewer than 20 companies are likely to survive; the determining factors are cash flow and channel capability, not technical differentiation.
Consolidation accelerating in utility-scale storage. The average bid success rate for large-scale storage projects fell from 23.5% in 2023 to 12.8% in Q1 2026. Procurement thresholds are rising rapidly , including requirements for 220 kV and above integration commissioning reports and new national standard thermal runaway propagation tests , reinforcing a winner-takes-more dynamic.
The divergence between "selling hardware" and "selling returns." Hiboou (2025 revenue RMB 11.61 billion, storage shipments 24 GWh up over 100% year-on-year, overseas gross margin >36%) and Narada Power (holding RMB 8.9 billion in storage orders yet suffering a collapsed cash position and 157 frozen accounts) represent two extreme outcomes within the same market. The dividing line is whether a company has transformed storage from hardware into a service , one that earns returns for asset owners in the spot electricity market.
Diverging overseas strategies: operational efficiency vs. local manufacturing. Deye's gross margin has consistently exceeded 50%, built on supply chain efficiency and global scale economies rather than brand premium. The collapse of GivEnergy in the UK (which ceased operations within 48 hours) illustrates the counter-lesson: manufacturing localization does not build a moat , operational efficiency does. The productive path, as demonstrated by Megarevo, Ginlong (Solis), and Aiswei, is multi-country certification combined with deep channel development.
Virtual power plants and energy service operations reaching scale. Pino Technology has obtained qualification as a virtual power plant operator and load aggregator in Guangdong Province and has deployed multiple operational AIDC power coordination projects. Infineon Source offers a complete electricity trading strategy platform. Hiboou's AI cloud platform optimizes spot market charge/discharge decisions. The underlying thesis: storage is not an energy cost , it is an energy asset.
Trade barriers reshaping the global installation map. India's ALMM battery cell list took effect June 1, potentially pushing India's 2026 installation forecast down to 35–40 GWac. US Section 232 tariffs are expected to take effect as early as late Q2 or Q3 2026. For Chinese manufacturers, localizing overseas production capacity , in Southeast Asia, the Middle East, and Europe , is becoming increasingly critical.
China's 2026 solar installations: short-term contraction, long-term intact. New installations in January–April totaled 50.91 GW, down 51% year-on-year; April alone was down 79%. However, China's 14th Five-Year Plan (2026–2030) identifies northern wind and solar bases, green computing power, and distributed energy development as long-term demand drivers. Grid absorption constraints will take time to resolve, but the short-term contraction does not change the long-term thesis.

V. China's Role: From World Factory to System Architect

In the next phase of the solar and storage industry, Chinese companies will occupy four overlapping roles:
Full-stack system architects. Sungrow, Huawei, BYD, and Envision have evolved from equipment manufacturers into full-chain solution architects spanning solar, storage, inverters, AI, and grid interfaces. This means Chinese companies are not merely winning contracts , they are shaping the technical standards and system frameworks that define the industry, shifting from "filling orders" to "writing the rules."
The world's dominant storage system exporters. China holds supply chain advantages across utility-scale, commercial and industrial, and residential storage. With domestic margins under pressure (utility-scale gross margins around 16%), overseas expansion has become the primary growth path , with rapid progress in Europe, Australia, Southeast Asia, and Africa, where margins are substantially higher than in the domestic market.
Exporters of new power system technology. Chinese companies now command a complete technology stack: grid-forming capability, solar-storage integration architecture, and AI energy dispatch platforms. As high renewable penetration spreads globally, other countries' grids will face challenges similar to those China is navigating today. This technology stack will travel with Chinese companies into international markets, creating a form of competitive moat rooted in technical standard-setting.
Pioneers of the space energy supply chain. GCL, Junda, JA Solar, and JinkoSolar have begun positioning in space solar, forming deep partnerships with China's commercial space sector (Galaxy Space, Ziwei Technology, the Lijian rocket program). As Chinese commercial launch costs fall rapidly, the synergy between the space and solar industries could produce a distinctive first-mover advantage within five to ten years.
