We apply very strict standards to the careful quality checks that all our components undergo, and to the power measurements carried out on our finished modules. Our in-house testing labs, which include two stations for testing cells delivered from our suppliers, provide a solid basis for producing top quality modules. Our customer complaint rate, based on all the units produced in our factory, currently stands at just 0.0045%.
Integrated quality and environmental management system in line with DIN EN ISO 9001 and 14001, and with OHSAS 18001
We don’t compromise on quality.
Continuous full process control and frequent spot checks using valid testing procedures mean that our customers can always be sure of extremely high quality standards.
Our supplier selection process is designed to make sure we get quality right from the outset. The companies undergo a rigorous audit and regular checks, and we conduct thorough inspections of all incoming goods. This approach ensures that our components always deliver the very best features. If you want to learn more about how we manage our suppliers, let us know and we will be happy to arrange a meeting with you.
