Canton Fair Phase III Closes: TOPCon/HJT Modules Lead New Energy Appliance Orders

From May 1–5, 2026, the third phase of the 139th Canton Fair concluded with notable transaction activity for TOPCon and HJT photovoltaic modules in the New Energy Appliances exhibition zone—accounting for over 42% of total PV-related order value. With 45% of buyers originating from Belt and Road Initiative countries—and multiple national delegations explicitly requesting compliance with IEC 63202-1:2025 hot-spot endurance certification and measured bifaciality ≥85%—this development signals a shift: overseas white-goods brands are integrating high-efficiency solar modules into appliance-grade quality control frameworks. Stakeholders in photovoltaics, home appliance export, international certification services, and supply chain logistics should monitor this trend closely, as it reflects evolving technical and procedural expectations at the intersection of energy and consumer electronics.

Event Overview

The third phase of the 139th Canton Fair took place from May 1 to May 5, 2026. During this period, TOPCon and HJT photovoltaic modules emerged as the leading成交品类 (primary transaction category) in the New Energy Appliances exhibition zone, representing more than 42% of total photovoltaic-related order value. Buyers from Belt and Road Initiative countries accounted for 45% of procurement activity. Several national buyer delegations specifically requested documentation confirming compliance with IEC 63202-1:2025 (hot-spot endurance) and verified bifaciality test reports showing ≥85%.

Industries Affected

Direct Export Trading Enterprises: These firms face tightening technical preconditions for market access—particularly in Belt and Road markets where certification alignment is now being treated as a de facto entry requirement, not just a competitive differentiator. Impact manifests in longer pre-sale validation cycles, increased documentation burden, and potential order delays if conformity evidence is incomplete or outdated.

Module Manufacturing Enterprises: Manufacturers supplying to new energy appliance OEMs must now treat module-level certifications—not just cell or system-level ones—as part of core product specifications. The demand for verified bifaciality ≥85% and IEC 63202-1:2025 compliance directly affects production testing protocols, lab capacity planning, and technical datasheet accuracy.

Certification & Testing Service Providers: Demand is rising for accredited testing against IEC 63202-1:2025 and standardized bifaciality measurement under real-world irradiance conditions. Providers must verify whether their current scope covers the 2025 edition of the standard and whether their reporting format meets procurement delegation requirements (e.g., signed test reports with traceable calibration records).

Supply Chain & Logistics Operators: Documentation integrity becomes operationally critical. Shipment releases may now require concurrent submission of certified test reports alongside commercial invoices and packing lists—especially for consignments destined for national procurement programs tied to Belt and Road infrastructure-linked appliance deployments.

Key Focus Areas and Recommended Actions

Monitor official updates on IEC 63202-1:2025 adoption timelines

While the standard was published in 2025, national regulatory transposition status varies. Exporters should track announcements from target-market national standards bodies (e.g., SAC in China, BIS in India, SASO in Saudi Arabia) to distinguish between voluntary buyer requests and imminent mandatory requirements.

Prioritize verification of bifaciality test methodology and reporting consistency

IEC 63202-1:2025 does not prescribe a single bifaciality measurement method. Buyers’ “≥85%” requirement refers to measured values—not simulated or nominal figures. Firms should confirm whether their test labs use rear-side irradiance conditions aligned with IEC TS 60904-1-2 and whether reports specify test setup (e.g., albedo, mounting height, rear-side sensor placement).

Distinguish between procurement delegation preferences and enforceable regulatory mandates

The 45% Belt and Road buyer share reflects observed purchasing behavior—not legal harmonization. Current requirements stem from buyer-led technical specifications, not binding import regulations. However, repeated inclusion in delegation briefings suggests early-stage standardization momentum; firms should treat these as leading indicators, not isolated incidents.

Update internal technical documentation workflows ahead of Q3 2026 tender cycles

Many Belt and Road national appliance procurement programs align bidding windows with fiscal calendars. Preparing certified test reports, updating product datasheets with compliant metrics, and training sales teams on standard terminology (e.g., “hot-spot endurance rating” vs. “thermal stability”) should be completed before August 2026 to support Q3 bid submissions.

Editorial Perspective / Industry Observation

Observably, this Canton Fair outcome functions less as a discrete commercial milestone and more as a procedural inflection point: it confirms that high-efficiency PV modules are no longer evaluated solely as energy components but are increasingly subject to the same verification rigor applied to integrated consumer appliances. Analysis shows the convergence is occurring at the specification level—not through formal regulation yet, but via coordinated buyer expectations across multiple national delegations. From an industry perspective, this signals growing technical interoperability pressure across traditionally siloed sectors (PV manufacturing and white-goods OEMs), where component-level compliance now influences system-level qualification. It is currently best understood as a strong market signal—not yet a binding compliance threshold—but one that is gaining institutional traction through repeat procurement language and cross-border delegation coordination.

This development underscores a broader shift: international buyers are treating module performance and reliability not as abstract technical parameters, but as embedded product attributes subject to end-use verification—akin to safety or EMC testing for household devices. Sustained attention is warranted because such alignment tends to precede formal regulatory codification by 12–24 months in emerging markets.

Conclusion: The 139th Canton Fair’s third phase highlights an accelerating integration of photovoltaic module specifications into white-goods procurement frameworks—driven primarily by Belt and Road market demand. This is not yet a regulatory mandate, nor a universal requirement across all export destinations. Rather, it is a focused, buyer-led technical expectation emerging in specific high-potential corridors. Current interpretation should emphasize preparedness—not panic—and prioritize verifiable, documented conformity over generalized capability claims.
