The new modules have four more cells than the former 50-cell panels of the S-Class Excellent series and can be fitted by one person. The chosen layout of the cell matrix means the efficiency has been given a considerable boost. The modules achieve an output of up to 225 Wp.
With the relaunch, the company says it is responding to customer calls for a high-output photovoltaics (PV) module with compact dimensions. The new version module is wider and shorter, resulting in improved statics and greater torsional rigidity on the roof. For the installation engineer, the new dimensions mean greater ease of handling during the installation process, shortening the overall fitting process.
The module now comprises 6 x 9 cells instead of the previous 5 x 10. The extra row of cells permits an efficient wiring concept that reduces the modules' internal resistance and thus improves yield. The S-Class Excellent module series is built at the group's own production plant at the company's Sonnenstromfabrik in Wismar, Germany. The first 54-cell modules will become available from the fourth quarter of 2010.
Following their market launch in Germany, they are also scheduled to go on sale in Spain, Italy, France, the Netherlands and Greece.
