Shingled Modules now possible with SmartCalc.CTM

Modules with shingled solar cells can now be analyzed with SmartCalc.CTM and paralell string interconnection is now available. The interconnection of solar cells by shingling increases the active cell area in photovoltaic modules. Cell-to module (CTM) gains and losses for this design change significantly compared to standard modules. At the IEEE PVSEC in Washington models were presented to calculate these gains and losses for shingled cells. These models are now also implemented in SmartCalc.

The key to efficient and powerful modules is an optimal cell-to-module (CTM) ratio. Interconnecting solar cells and integrating them into a solar module comes along with different optical and electrical effects. A profound understanding of all factors which influence the module efficiency is essential to derive methods to decrease the losses or to increase the gains caused by module integration. Several CTM calculation methods have been published in the past, mostly not available to a wide number of users in the form of a user-friendly tool.
