One of the most striking features of the REC TwinPeak Series is its use of smaller cells. These are in fact, regular 156 mm (6 in) cells cut in half. The smaller size reduces internal resistance, increasing output, and has allowed REC to take a new approach with the layout, removing one cross connector, which enables greater inter-cell spacing and an increase in captured light. The removal of the cross connector is aided by a three-effect of this is to split the cell strings into two, i.e., six strings in total,controlled by three bypass diodes as shown below (fig.1). With this,the module takes on a diff which can help achieve an increase in overall energy yield.
