AQM award for Stäubli proves the outstanding PV connector quality


Allschwil/Switzerland, September 11, 2023 − Stäubli’s MC4-Evo 2 connector wins prestigious AQM (All Quality Matters) Award 2023 for exeptional performance and durability provided by TÜV Rheinland China.

Renewable energy is continuing to make strong inroads into the global energy supply. Photovoltaics are leading the way with substantial annual growth of more than 20 % ahead of all renewable energy sources. The efforts and commitment on the part of manufacturers to make solar power production safer are therefore even more important. A decisive factor here is the quality of all components of a system.

The AQM award by TÜV Rheinland China

As the world’s leading technology and service provider with over 40 years of experience in the photovoltaic industry, TÜV Rheinland tests and certifies technical components for safety, reliability, and durability. For nine consecutive years, the organization has hosted the AQM Solar & ESS Congress “All Quality Matters” in China with awards in various categories. The AQM Award is recognized for its objective and credible evaluation process and authoritative neutral selection mechanism. The samples to be tested are randomly selected from mass production. In China, the largest photovoltaic component manufacturing country, the AQM Award is the most prestigious industry award. The country’s component production accounts for about 71 % of the world’s total capacity.

Stäubli, the leading provider of innovative and reliable connectivity solutions, is proud to announce that its original MC4-Evo 2 PV DC connector passed the testing procedure for the award with distinction as the best product in the category PV connector.

The performance tests included:
