Worry-free Use
Yang Ming Photovoltaic Technology regards quality as its life and adheres to the 'Three Zero Principles': zero-defect design, zero-tolerance testing, and zero-distance service. Using aerospace-grade materials + nano-composite technology, all products have passed 12 international certifications such as SGS, and 15 automated production lines guarantee millimeter-level precision. With continuous technological innovation, we have fulfilled our quality promise of '20 years of worry-free use'.

TESTING & QUALITY INSPECTION

Raw Material Control
Establish a "raw material ID card" traceability system. Each batch of resin substrates must pass 6 core index tests such as density, melting point, and impact resistance to ensure that they meet aerospace-grade material standards and eliminate quality risks from the source.
Smart Production
The entire line is equipped with an SPC process control system. 27 QC control points are set at key nodes of 15 automated production lines. The tile molding accuracy is monitored in real time through online detectors to control the defective rate within 0.3‰.
Extreme Verification
5000 hours of accelerated aging test in a low temperature of -40℃ to a high temperature of 85℃, and fire-grade combustion tests and acoustic performance tests are carried out simultaneously to ensure that the product can withstand extreme working conditions.
Precision Testing
Introduce AI visual recognition + three-coordinate measuring instrument to perform micron-level geometric accuracy testing (up to 0.02mm) and surface defect screening on finished products, and cooperate with acoustic laboratories to verify sound insulation performance.
Global Certification
Each batch of products must pass the CNAS certified laboratory test and obtain ISO9001 quality management system certification at the same time, comply with 12 international standards such as EU CE and US ASTM, and smooth global access channels.
Safe Delivery
Double-layer packaging with earthquake-resistant wooden box + moisture-proof inner film, 1.2-meter drop test before leaving the factory, equipped with intelligent logistics tracking system to ensure the safety of products from workshop to construction site.
