Design, Manufacturing and Reliability of Shingle Matrix Modules

Fraunhofer ISE, in collaboration with M10 Solar Equipment GmbH, addresses the demand for efficient, visually appealing and shading resilient solar panels by introducing and developing the shingle matrix technology. The matrix technology also ensures efficiencies surpassing those for ribbon-connected modules due to the increased cell packing density. This study demonstrates significant progress in advancing shingle matrix technology towards com-mercial viability. Optimization of shingle cutting, shingle placement precision, and electrically conductive adhesives (ECAs) curing conditions were successfully realized in this study to establish a reliable automated interconnection. Eleven full size shingle matrix modules were produced by industrial scale processes and underwent IEC 61215-2:2021-based climate chamber tests and tests addressing the electrical safety under combined environmental stresses according to IEC 61730. The modules showed performance degradations < -3.4% aligning with IEC 61215-2 criteria. These efforts ensure matrix technology's stability and safety, facilitating broader industry acceptance and demonstrate the commercial potential of this innovative technology.
