Finite element method (FEM) simulations of the physical product behavior of PV modules and their components can quickly reveal optimization potential with regard to design and the interaction of materials. This greatly reduces the need for prototype construction. In addition, root causes of failures occurring during operation can be analyzed in great detail.
We use FEM simulations to examine a wide range of physical influences on the PV module and its components, such as the module frame or the substructure. For example, we simulate thermomechanical stresses during production, in tests according to the IEC 61215 standard or under real environmental loads in order to identify and thus avoid potential defects already during development.
With FEM, PV modules can be developed and optimized widely computer-based. Through the interface with CAD programs and the use of a High Performance Computing Clusters (HPC cluster), we are able to simulate very complex and thus computationally expensive geometries and issues in the field of solar energy.
