9th Performance Modelling and Monitoring Workshop

The 9th PV Performance Modeling Collaborative (PVPMC) Workshop to be held in Weihai, China on December 5th and 6th 2017, is co-organized by the Solar Research Institute of HIT, Fraunhofer ISE and Sandia National Laboratories. SmartCalc.CTM and selected cell-to-module anaylsis results will be presented by Max Mittag. The workshop brings together solar PV professionals and researchers to learn about and discuss PV performance modeling. It is an interactive workshop that provides valuable information for modelers, model developers, and other users of PV performance model results.

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.

Publication in Photovoltaics International

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.
