Qualifying and Certifying Photovoltaic Modules for You
High-quality photovoltaic (PV) modules are subject to a number of requirements. First, they have to deliver the guaranteed rated power reliably, while withstanding an extremely wide range of environmental conditions. They must also be safe and durable, ensuring the system’s high yield over the long term. And, they should also be able to generate the total amount of energy that was used to manufacture them in the shortest possible time. To top things off, they need to be commercially viable. But, with testing services from TÜV Rheinland, you can fully certify the quality of your PV modules. We can carry out comprehensive tests in our test laboratories that comply with applicable national and international standards.

Qualification and Certification of Photovoltaic Products
We test your standardized PV systems and PV components – including PV modules, grid-connected systems, power inverters, frames, cables, and connectors – according to national and international standards. If no applicable standards exist, our experts can carry out tests based on TÜV Rheinland specifications.
In addition to laboratory testing, certification of PV modules and PV components also covers the manufacturing facilities.
In our accredited laboratory, we test selected samples to determine whether your products satisfy applicable standards. The test criteria – transparent to customers at all times – are documented along with the test results.
Our experts carry out additional periodic quality and product audits at your production facilities. That way, we can ensure that all PV modules are manufactured with the same materials and processes as the samples tested in the laboratory and that product quality is consistent.
