ACWA Power Tender Tightens LID Limit for TOPCon/HJT Modules

The exact time of the event is not explicitly stated in the source input, but the disclosed tender signal is clear: ACWA Power has introduced a stricter LID threshold in its global procurement for TOPCon and HJT modules, setting a maximum of 1.0% under a tightened application of IEC TS 63209-1:2026. For module manufacturers, upstream material planners, certification-related service providers, and project procurement teams, this is worth close attention because it shows how buyer-side technical requirements can move ahead of existing market reference thresholds and begin shaping qualification, sourcing, and delivery expectations.

What the tender document explicitly requires

According to the provided information, ACWA Power, described as a leading Saudi developer, issued a global request for proposals for TOPCon and HJT modules for the Al Shuaibah III photovoltaic project on June 30, 2026, under RFP Ref: ACWA-SOL-2026-07. The tender requires bidding modules to meet an LID degradation limit of no more than 1.0%.

The requirement is described as a tightened version based on IEC TS 63209-1:2026. The same input states that this threshold is stricter than the current 1.2% limit referenced for KATS in Korea.

The provided summary also states that this move is expected to accelerate a higher global quality benchmark for TOPCon and HJT modules and push leading Chinese manufacturers to prepare lower-LID wafer selection and encapsulation processes earlier.

Why this matters across procurement and delivery chains

Buyer specifications are becoming a practical compliance gate

From an industry perspective, the immediate impact is on procurement qualification rather than on public regulation alone. When a project owner sets a hard LID ceiling in a tender, technical compliance moves from a product performance discussion into a bid-entry requirement. Module suppliers pursuing such tenders may need to review whether their existing technical documents, test reports, and bid materials can demonstrate alignment with the stated threshold and the referenced testing basis.

Manufacturing decisions may face earlier scrutiny

Analysis shows that module makers, especially those supplying TOPCon and HJT products into international project tenders, may be affected at the process and material-selection stage. The reason is straightforward: an LID threshold that is tighter than another existing market reference can influence how suppliers prepare wafers, cell processes, encapsulation approaches, and supporting technical evidence. The effect is not limited to product design; it can extend into internal qualification, supplier coordination, and pre-delivery verification.

Testing and certification support may need closer alignment with tender language

Certification-related firms and testing service providers may also see a more specific documentation burden. What deserves closer attention is not only whether a module performs well in general, but whether the evidence package matches the exact tender wording, including the cited standard basis and the tightened performance condition. Where project bids depend on narrow technical thresholds, differences between general product literature and tender-specific compliance documentation can become commercially significant.

Export and project delivery teams may need tighter document control

For export-facing suppliers and delivery teams, the likely pressure point is the consistency of technical files submitted during bidding and execution. Observably, once a buyer defines a hard limit, questions may arise around report versioning, specification alignment, product traceability, and consistency between the offered module configuration and the tested configuration. Even without additional enforcement details in the provided input, this kind of requirement can affect bid readiness and downstream delivery confidence.

What companies should watch next

Check whether current bid documents support the 1.0% threshold

Analysis shows that suppliers targeting similar tenders should first review whether current technical submissions clearly support an LID value at or below 1.0% under the referenced basis. This includes product specifications, test summaries, declarations, and any tender annexes that may need exact wording consistency.

Track how low-LID process claims are evidenced

The provided summary points to earlier deployment of low-LID wafer and encapsulation approaches as a likely response path for leading Chinese manufacturers. It is more appropriate to understand this as a practical preparation signal rather than a confirmed market outcome. Companies should therefore watch how process-related claims are translated into verifiable documentation during bidding and supply qualification.

Monitor whether this remains project-specific or spreads through buyer practice

What deserves closer attention is whether the 1.0% requirement remains limited to this procurement event or begins to appear more broadly in future tenders and qualification frameworks. At this stage, the input supports a clear tender requirement, but it does not establish a wider mandatory rule across all markets or projects.

Prepare for closer coordination between sales, quality, and supply teams

Because the issue sits at the intersection of technical performance and commercial acceptance, companies may need tighter coordination across bid management, engineering, quality assurance, and supplier management. The key point is not to assume that a product accepted under one market reference threshold will automatically satisfy a stricter buyer-defined condition in another tender context.

How this signal should be read for now

Observably, this development is best read as an execution signal from a major project buyer rather than as a fully generalized regulatory shift. The confirmed fact is the tender requirement itself. The broader implication, by contrast, remains an industry interpretation: buyer-side procurement language may begin to function as an early mechanism for raising practical quality benchmarks before those expectations are uniformly reflected across all markets.

Analysis shows that the most relevant question now is not whether stricter LID expectations exist in the abstract, but how consistently they will be enforced in tender review, supplier qualification, and later delivery verification. That is why ongoing attention to future tender wording, technical review criteria, and market response will matter more than headline comparisons alone.

A stricter threshold, but still a developing market signal

In summary, the ACWA Power tender matters because it turns a tighter LID expectation into a concrete bid requirement for TOPCon and HJT modules. That has practical implications for manufacturers, procurement teams, testing support providers, and export delivery functions, particularly where compliance evidence must be tied closely to tender specifications.

At the current stage, it is more appropriate to understand this development as a meaningful procurement and quality signal with potential spillover into broader market practice, rather than as a settled cross-market rule change. The next phase to watch is how similar requirements appear in subsequent tenders, supporting documents, and supplier responses.

Basis of this article and points still requiring verification

This article is generated based on the user-provided news title, event timing note, and event summary. The specific official source link was not provided in the input, so the underlying document trail still requires continued verification.

For this type of development, relevant source categories typically include official tender notices, buyer-issued procurement documents, regulator or trade authority releases, standards organization materials, industry association communications, and reporting by authoritative trade media. Further observation is still needed on later rule interpretation, certification and testing application, changes to tender documents, industry feedback, and how companies implement related technical and delivery adjustments.
