SolarWorld modules receive top grade "very good" in PV+Test


The Sunmodule Plus SW 245 poly achieves the top grade in module durability from TÜV Rheinland and Solarpraxis

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 SW 245 poly 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.

The PV+Test testing system allocates grades according to the German grading system used in schools: A maximum of 100 points are allocated. A minimum of 90 points are required to receive the grade "very good", and at least 50 points are required to receive the grade of "adequate."
