November 1, 2026 will become an important turning point for photovoltaic cleaning equipment entering large-scale ground-mounted power station projects in Brazil. With INMETRO updating the scope of application of Portaria 249/2023, fully automatic rail-mounted photovoltaic cleaning equipment will be brought under mandatory certification management, while EMC immunity testing and Portuguese-language manuals will also be newly required. This change deserves close attention from equipment manufacturers, export companies, purchasers, certification and testing service providers, and parties involved in project delivery, because it is now directly linked to whether products can enter the tender lists for large-scale ground-mounted power station projects in Brazil.

What confirmed matters are covered by this regulatory adjustment

The confirmed information indicates that on August 2, 2026, the Brazilian National Institute of Metrology, Standardization and Industrial Quality (INMETRO) issued an announcement expanding the scope of mandatory certification under Portaria 249/2023 to fully automatic rail-mounted photovoltaic cleaning equipment, covering systems composed of fixed rails and mobile cleaning units.

At the same time, the new requirements include electromagnetic compatibility (EMC) immunity testing and localized Portuguese-language manuals.

The new regulation will become mandatory on November 1, 2026. According to the information provided, products without certification will currently be unable to enter the tender lists for large-scale ground-mounted power station projects in Brazil.

The initial impact will fall on the coordination of market access, procurement, and delivery

Equipment suppliers shipping to Brazil

For manufacturers and export companies, this change will first affect market access requirements. Fully automatic rail-mounted models that were previously outside the scope of mandatory certification now need to be reassessed in terms of product definition, test preparation, and documentation completeness in accordance with the updated certification requirements. The main business impacts will be reflected in certification arrangements, technical document preparation, shipment schedules, and compliance documentation for project tenders.

From an industry perspective, these companies now need to focus on verifying whether their products fall within the newly covered scope and whether the EMC immunity testing and Portuguese-language manual requirements will affect their existing documentation systems, prototype preparation, and delivery schedules.

Owners and integrators involved in project procurement and tenders

For purchasers, general contractors, or parties involved in tender organization for large-scale ground-mounted power station projects, this update affects supplier selection and the boundaries of tender eligibility. Since uncertified products will be unable to enter the tender list, preliminary procurement reviews, technical bid coordination, and qualification document verification may all become correspondingly stricter.

From an analytical perspective, procurement teams need to focus not only on equipment performance descriptions, but also on certification status, the definition of applicable product categories, and whether supporting technical documentation meets the new requirements, so as to avoid inconsistencies in compliance conditions during the tender or award stage.

Certification and testing services

For certification-related companies and testing service providers, the direct impact of this change is the expansion of the service scope, along with the newly specified requirement for EMC immunity testing. Relevant business activities may focus on product classification confirmation, test item matching, document review, and localized manual support.

These organizations will subsequently need to pay greater attention to whether the implementation criteria are further clarified, particularly how fully automatic rail-mounted integrated systems are classified, how the corresponding documentation should be prepared, and how specific steps in the certification process should be coordinated.

Delivery and after-sales support

For service providers responsible for project delivery, installation coordination, or after-sales support, the new Portuguese-language manual requirement means that the preparation of accompanying materials, operating instructions, and delivery documents must be adjusted accordingly. Although the available information does not provide more detailed implementation rules, language compliance for documentation has shifted from an ancillary matter to part of the actual access requirements.

This means that when preparing shipment and delivery support, relevant companies need to include manual localization in their preliminary checks rather than waiting until close to delivery to handle it as a supplementary task.

Several practical points that require closer attention at this stage

First confirm whether the product falls within the newly covered scope

The first task for companies is not a general interpretation of the policy, but rather a determination of product boundaries. The information provided clearly states that fully automatic rail-mounted photovoltaic cleaning equipment, as well as integrated systems combining fixed rails and mobile cleaning units, have been included in the scope of mandatory certification. For companies with relevant models in their product portfolio, this step will directly affect subsequent certification, quotation, tender, and delivery arrangements.

Prepare testing requirements and technical documentation simultaneously

The new EMC immunity testing requirement means that companies cannot determine eligibility for market entry solely on the basis of existing equipment documentation. From an analytical perspective, greater attention should be paid to whether test preparation and technical document organization are progressing simultaneously. Otherwise, even if the product design itself has not changed, gaps may arise during tender documentation or access reviews.

Do not treat manual localization as a post-delivery task

This update also introduces a requirement for localized Portuguese-language manuals. For companies, this is not merely a translation task; it also concerns the consistency of accompanying documents, the completeness of delivery documentation, and their correspondence with certification materials. Since the current information does not provide specific review criteria, it is more appropriate to regard this as an item that should be included in the documentation review checklist at an early stage.

Monitor subsequent changes to tender documents and implementation criteria

Since the confirmed facts already point to restrictions on eligibility for tender lists, companies need to continue monitoring whether relevant project documents, supplier qualification requirements, and the submission methods for certification evidence will be further refined. At this stage, it is not advisable to regard all implementation outcomes as fully determined, but moving certification status forward into commercial and delivery decisions is already an operational necessity.

This is more like a clear implementation signal than a matter for general monitoring

From an observational perspective, this information is better understood as an access-related change that has entered the implementation stage, rather than merely a regulatory trend for market reference. This is because the information provided includes not only an expanded scope of application and new requirements, but also a clear mandatory implementation date, directly linked to tender lists for large-scale ground-mounted power station projects.

At the same time, it should be recognized that the currently available public information focuses mainly on the scope expansion and the new requirements themselves. More detailed certification procedures, how project parties will conduct specific verifications, and how different participants will coordinate documentation remain matters requiring further observation. Therefore, the industry's understanding of this information should not remain at the news level, but should be implemented in practical arrangements for product classification, certification preparation, document management, and tender response.

The practical implications for market participants are becoming clearer

Overall, the core message conveyed by this INMETRO update is relatively clear: Brazil's compliance boundaries for photovoltaic cleaning equipment are extending to fully automatic rail-mounted models, and certification, testing, and localized documentation requirements are now directly linked to market access.

Viewed rationally, this does not automatically mean that all related business activities will immediately be affected to the same extent. However, for equipment suppliers and procurement-related parties planning to enter large-scale ground-mounted power station projects in Brazil, this is no longer a regulatory development that can be deferred. At present, it is more appropriate to understand this information as a compliance signal with a clearly defined implementation date, while continuing to monitor subsequent certification criteria, changes to tender documents, and market implementation feedback.

Basis of this article and directions for follow-up verification

This article was generated based on the information title, event date, and event summary provided by the user. The key basis includes information on INMETRO's expansion of the scope of application of Portaria 249/2023, the mandatory implementation date of November 1, 2026, the EMC immunity testing requirement, the requirement for localized Portuguese-language manuals, and the statement that uncertified products cannot enter the tender lists for large-scale ground-mounted power station projects in Brazil.

For events of this type, continued verification should normally be conducted against official announcements, publications by regulatory authorities, standards or certification documents, project tender documents, industry association information, and reports from authoritative media. Since no specific official source links were provided in this input, the relevant links and more detailed implementation requirements still require ongoing verification.
