On July 28, 2026, the European Union published a revised CE compliance guide through the Official Journal of the European Union, OJ L 205/2026, explicitly bringing intelligent photovoltaic cleaning equipment within the scope of the IEC/EN 62443-3-3 cybersecurity standard. According to the information disclosed, starting in January 2027, relevant equipment with IoT remote control, cloud platform access, or firmware OTA upgrade functions will be required to undergo a cybersecurity assessment by an authorized NB body and bear the CE+Cyber mark. This change deserves close attention from photovoltaic cleaning equipment manufacturers, export trading companies, and teams responsible for certification and delivery, as it directly affects EU market access, certification arrangements, and product development schedules.

What compliance requirements have been clarified by this adjustment?

The confirmed information shows that the European Union published a revised CE compliance guide in the Official Journal of the European Union, OJ L 205/2026, on July 28, 2026, further clarifying the applicability of the IEC/EN 62443-3-3 cybersecurity standard to intelligent photovoltaic cleaning equipment.

According to the summary, starting in January 2027, equipment with IoT remote control, cloud platform access, or firmware OTA upgrade functions must undergo a cybersecurity assessment conducted by an authorized NB body and bear the CE+Cyber mark after meeting the relevant requirements.

The information provided also indicates that these changes will affect the certification pathways and development cycles of Chinese manufacturers exporting to the EU.

The impact will not be limited to the certification process itself

Export-oriented equipment manufacturers will face pathway adjustments first

From an industry perspective, photovoltaic cleaning equipment manufacturers directly targeting the EU market will be affected first, because the new requirements target products with networking, remote control, or OTA capabilities. The main impacts will be reflected in product definition, certification preparation, testing arrangements, and launch schedule management. Of particular importance is that companies can no longer understand CE solely as a matter of traditional safety or electrical compliance. Models with intelligent functions will also involve cybersecurity assessment requirements.

Foreign trade and channel teams need to reassess delivery schedules

For direct trading companies, overseas sales teams, and channel partners, the impact is more likely to arise in customer communication, order commitments, and delivery scheduling. Based on the analysis, once a product requires an additional assessment by an authorized NB body, the existing certification and shipment arrangements may need to be brought forward. This is particularly relevant to project-based deliveries for EU customers, where greater attention will need to be paid to whether equipment function descriptions, certification status, and delivery documents are consistent.

The importance of R&D and firmware management will increase

For teams responsible for hardware design, control system development, cloud connectivity, and firmware upgrade functions, this change is not simply “one more certification.” Based on current observations, as long as equipment has remote control, cloud platform access, or OTA upgrade capabilities, these functions themselves will become key boundaries in compliance determinations. Accordingly, R&D, testing, firmware release, and version management will all need to be reviewed in greater detail around whether assessment requirements are triggered.

Coordination pressure on certification services and the supply chain will also increase

For teams responsible for certification coordination, project management, supply chain services, and export documentation, the new requirements mean that the complexity of cross-departmental coordination may increase. The main impacts will be reflected in document preparation, assessment coordination, prototype management, consistency of delivery documents, and customer acceptance communication. Particularly when multiple models are exported in parallel, which models are applicable, when assessments are completed, and how the marking is implemented will all become key practical issues.

What practical issues should companies focus on now?

First define which products fall within the applicable scope

Based on the information currently available, equipment with IoT remote control, cloud platform access, or firmware OTA upgrade functions will be directly applicable. For companies, the first task is not to discuss the impact in general terms, but to define the product boundaries and confirm which existing export models, models under development, and models planned for upgrades have already triggered the relevant requirements.

Include certification scheduling in development and shipment plans

The confirmed facts show that, starting in January 2027, equipment will need to pass a cybersecurity assessment by an authorized NB body and bear the CE+Cyber mark. Based on this timeline, companies need to arrange certification preparation and assessment submission earlier in practice, avoiding situations in which compliance work is found to be necessary only after development is completed, thereby compressing the delivery window.

Distinguish between policy wording and the gap to business implementation

Based on the analysis, the guide has provided a clear direction, but at the implementation level companies still need to translate the policy requirements into specific actions, including document preparation, consistency of function descriptions, customer version confirmation, and implementation of the marking. In other words, the policy signal is already clear, but when applied to different models, customer orders, and delivery batches, each item still needs to be checked individually.

Prepare communication guidelines for customers and partners in advance

For export sales, project delivery, and after-sales support teams, the current focus should not be limited to internal compliance; consistency in external communication is also important. Whether equipment for EU customers falls within the applicable scope, whether the authorized assessment has been completed, and when the CE+Cyber mark can be applied may directly affect purchasing decisions and delivery confirmation.

This is more like an extension of the market-access logic

Based on current observations, this information should not be understood merely as the addition of a separate certification procedure. It is more appropriate to view it as a further extension of the EU’s market-access logic for intelligent equipment. It does not target all photovoltaic cleaning equipment, but rather equipment types that already have networking, remote control, and upgrade capabilities.

At the same time, this change already has a clear timeline and is therefore not merely a long-term signal. However, in terms of actual industry implementation, the degree of impact on different companies will still depend on their product configurations, the proportion of their EU business, and their existing certification preparations. Based on the information currently available, the more appropriate assessment is that the regulatory direction is clear, while the specific implementation impact still needs to be continuously monitored in light of each company’s products and order structure.

For the industry, the focus is on reorganizing processes in advance

Overall, the core message released by this revision to the CE compliance guide is clear: once photovoltaic cleaning equipment has intelligent capabilities such as IoT remote control, cloud platform access, or OTA upgrades, compliance issues should no longer be handled solely according to the approach used for traditional equipment when entering the EU market. For the companies concerned, this information is more appropriately understood as a regulatory change that has already established clear requirements and needs to be incorporated into R&D, certification, and delivery processes in advance, rather than as a generalized trend that can be addressed later.
