4. 1 PV Module Design, Manufacture, Performance and Reliability
Summary / Abstract:
The use of photovoltaic technologies is increasing rapidly worldwide. PV modules are required to pass several standardized mechanical tests to ensure their long-term performance under various climate conditions, with often challenging snow and wind loads. These tests are costly and take a long time, it is therefore beneficial to use numerical approaches in order to reliably model the mechanical strength of PV modules while under design phase. The choice of module components; e.g. framed vs. frameless, double-glass vs. glass-backsheet have consequences on the structural strength of modules, just as the conditions of their fixation to their fixed-tilt or tracked support.
