    EVA / Glass / Back Sheet / Aluminum Frame / Junction Box

    EVA

    Reliable quality, high transparency

    Excellent anti-PID and anti-UV performance

    Back Sheet

    Reliability and stability guaranteed through a low water vapor permeability of the fluorine-containing back sheet in extreme environmental conditions

    Junction Box

    Best diode suppliers to reduce the formation of hot-spots

    High-quality sealed junction boxes guarantee the sealing

    Glass

    Glass surface with a closed nanostructure of the surface  of our anti-reflective coating improves the durability and stain resistance of the module

    Reliable quality and highest light transparency

    Excellent scratch resistance

    Alu-frame

    Top-quality surface treatment and higher Leitungsdichte guarantee outstanding corrosion resistance and mechanical strength of the modules

    Certified salt mist and ammonia resistance

  • Tests and certifications

    Manufacturing Process Inspection / Mechanical Test / Long-term Reliability Tests / Environment Endurance Tests

    Leading quality-management-system and excellent quality assurance of products

    100% automated in-house module manufacturing to guarantee product quality and performance

    The laboratories of JA Solar’s module manufacturing facilities are TÜV SÜD- and ETL-certified. The manufacturing processes and quality are tested by having our module manufacturing facilities inspected by independent institutes like PI-Berlin and Solar-IF.
