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.

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:
• Thermal shock
• Weather resistance test, cold impact test, IP protection and dielectric strength
• Lower temperature test, dry heat test, IP protection and dielectric strength
• Temperature rise test, bending test, IP protection and dielectric strength

The outstanding MC4-Evo 2 characteristics
The Stäubli MC4-Evo 2 connector is a highly dependable photovoltaic connector with several outstanding features that set it apart from the competition. One of its most outrageous features is its ability to withstand extreme weather conditions. Its innovative design allows the connector to operate reliably over the long term at temperatures up to at least 105 °C, at elevations up to 5000 m a.s.l., and below water for seven days at a depth of 1m. Such characteristics make it one of the most resilient PV DC connectors in the market.

Weigang HONG, Director Stäubli Electrical Connectors China comments: «We are very honored to have been awarded. This AQM Award confirms our world-leading position as a supplier of high-quality PV DC connectors and the success of our Original MC4 product portfolio which is the most installed worldwide with more than 50 % of the globally connected capacity. At the same time the AQM Award also underlines our total commitment to high quality in all aspects to make the PV industry safer. Because, PV safety matters.»
