Not all Solar Panels are the same – and in fact there can be big differences in performance between panels with similar specifications.
It pays to ensure the panels you buy not only perform as they should but also that they will continue to do so over an extended period of time.
When it comes to selecting a module manufacturer, investment security acts as a decisive factor. In order to provide orientation during this selection process, Solarpraxis AG together with TÜV Rheinland introduced the comparison test “PV+Test”. This test answers the question as to how reliably a module achieves the level of performance estimated in its calculation of return on investment.
The Sunmodule Plus poly solar panel from SolarWorld is the only module to achieve a perfect “very good” grade according to current testing regulations.
The test evaluates aspects such as durability, electrical safety, production quality, installation instructions, ease of installation and guarantee. The SolarWorld module achieved the highest grade in temperature performance and low-light performance. Especially when it comes to production quality, which is a decisive factor in the durability of the module, the testers’ assessment was definitive: Completely fault-free.
“This result serves as further proof of the fact that trusting in SolarWorld quality pays off for customers,” says Dr.-Ing. E. h. Frank Asbeck, CEO of SolarWorld AG, of the test results. “And it validates our strategy of consistently relying on first-class “Made in Germany” technology,” continues Asbeck.
The modules to undergo testing are purchased discretely by TÜV Rheinland and Solarpraxis through normal purchasing channels, and testing spanning a timeframe of several months follows at TÜV Rheinland’s solar laboratory in Cologne. Ongoing performance measurements, which are done before testing is begun as well as after each testing phase, are especially important, as performance is crucial for a good return on investment – especially after mechanical demands and a longer service life.
