    Sunway High Effciency 550W Half Cell Solar Panel - Sunway Solar
    INMETRO certification is a mandatory legal requirement for importing, selling, and installing solar panels in Brazil, ensuring compliance with safety, performance, and quality standards (Ordinance No. 004/2011). Panels are rated from 'A' (best) to 'E' based on energy efficiency, with popular compliant models including high-efficiency bifacial, TOPCon, and half-cell technologies ranging from 530W to 590W. 
    Key Aspects of INMETRO Solar Panels 
    • Mandatory Standards: Panels must adhere to international standards (IEC 61215/61730).
    • Performance Labeling: Panels come with the Etiqueta Nacional de Conservação de Energia (ENCE) label, which denotes the efficiency rating from A–E.
    • Fire Safety Regulations: As of late 2023, INMETRO intensified safety requirements (Ordinance No. 515) regarding fire prevention in photovoltaic systems.
    • Inspection Intensity: Following the discovery of fraudulent power ratings on some panels, INMETRO announced heightened inspection efforts and laboratory testing for the 2025–2026 period to ensure compliance.
    • Certified Brands & Models: Major brands (e.g., Jinko, Longi, Trina) produce INMETRO-certified 550W–590W bifacial/monocrystalline modules tailored for the Brazilian market. 
    Certification Process
    The certification is a "Type 5" process, which involves: 
    1. Product Testing: Laboratory assessment of safety and performance.
    2. Factory Audits: Evaluation of the manufacturing quality management system.
    3. Recertification: Necessary every four years. 
    Ensure that any solar modules purchased for projects in Brazil have the official INMETRO label and are verified against their active product list to guarantee, as mentioned in, safety and high performance, as mentioned in.
