There're 7 major inspection procedures for Each piece solar panel during production :


A: 3 times EL testing to ensure panel without micro-break/invisible break(normal manufacturer only test 1 or 2 times);


B: 3 times appearance inspection to ensure panel without defect (normal manufacturer only inspect 1 or 2 times);


C:1 time power testing, power inspection tolerance +/-0.1watt(normal manufacturer's power inspection tolerance is +/- 1-2watt), we ensure each panel has enough power output; besides the standard inspection, each production procedure will inspect the upwards procedure;




TUV Quality assurance testing



l  Thermal cycling test


l  Thermal shock test


l  Thermal/Freezing and high humidity cycling test


l  Electrical isolation test


l  Hail impact test


l  Mechanical, wind and twist loading test


l  Salt mist test
