“We are pleased to announce that our Series 3 Black Module is the first thin-film module in the world to pass two of the most difficult and strenuous independent tests with module durability and reliability, the Thresher test and the even more harsh long-term sequential tests, both evaluated by TUV Rheinland,” noted Hughes.

First Solar had introduced the Series 3 Black Module earlier in 2013, noting its harsh environment capabilities as well as improved performance characteristics.

“First Solar's success in these test places us among an exclusive list of only four other module manufacturers to demonstrate this market leading capability,” added Hughes in the call. “It also emphasises that while we continue to make significant investments in the redesign of our modules to increase efficiency and reduce cost, we don't sacrifice quality and performance in order to do so. Instead, we are creating a unique market offering that maximises value while minimising risk.”

China-based PV module manufacturer, Seraphim Solar System, was the first to receive the new Thresher certification, conducted by TÜV SÜD, followed quickly by JA Solar, using the same testing house.

According to a recent announcement from TÜV SÜD, three Chinese module manufacturers had been issued Thresher certificates, without identifying the companies.
