On June 24th , 2009 Sunfilm AG (Großröhrsdorf, Germany) announced that all its larger size thin-film solar modules have now also received IEC 61646/EN 61730 certification. These larger size modules include Model F (2.6 x 2.2m), Model L (2.6 x 1.1m) and Model W (1.3 x 2.2m). Earlier this year Sunfilm had already received IEC certification for its Model SN2 (1.7 x 1.1m) and Model Q (1.3 x 1.1m). IEC certification means that the module performance specification has been verified by one of Germany¡¯s TÜV institutes (InterCert, Bonn), considering certain mechanical, electrical and environmental test conditions.   For the Models F, L, W and Q, all critical thin film coatings are performed on large (2.6 x 2.2m) glass substrates. Depending on customer requirements, these large substrates are then used at full size or cut down to half-size or quarter-size substrates and further processed to fully functional photovoltaic modules. Model SN2 is directly produced on 1.7 x 1.1m substrate.

"The IEC certification of our larger size modules is very significant, because it means our customers now have a selection of five certified module formats that allow them to choose a module size that best fits their application. Such size-optimization can result into considerable project cost savings", says Dr. Sicco Westra, Sunfilm's Chief Business Development Officer.
