Photovoltaic Module/ Component/ Material Testing

The National Center for Quality Inspection and Testing of Solar Photovoltaic (PV) Products (referred to as the "National PV Center") is an accredited testing laboratory by CNAS and CMA, as well as a CB laboratory authorized by the IECEE (IEC System for Conformity Assessment Schemes for Electrotechnical Equipment and Components). The National PV Center has established comprehensive testing facilities and a professional technical team. It possesses capabilities for a range of environmental reliability tests on PV modules, including mechanical load, wet leakage current, insulation performance, ground continuity, humidity-freeze, thermal cycling, damp heat, and more. It can also perform power measurement, EL (Electroluminescence) defect detection, temperature coefficient analysis, IAM (Incidence Angle Modifier) performance evaluation, and PAN file testing for various types of PV modules, as well as other key inspections. Furthermore, we provide comprehensive testing and certification services for key products such as PV inverters, committed to offering high-standard, international technical support and quality assurance for the PV industry in China and globally.
