Currently, the accuracy of modeling a photovoltaic (PV) array for fault diagnosis is still unsatisfactory due to the fact that the modeling accuracy is limited by the accuracy of
EPJ Photovoltaics, an Open Access journal in Photovoltaics, which publishes original, peer-reviewed papers focused in the field of photovoltaic solar energy conversion Development and testing of light-weight PV modules based on
In the field of vehicle-integrated photovoltaics (VIPV), we identified 4 relevant norms that describe testing related to mechanical and thermomechanical failure modes. IEC 61215 for PV modules: thermal cycling (10.11), (static) mechanical load (10.16), hail test (10.17). IEC TS 62782 for PV modules: Cyclic (dynamic) mechanical load.
Herein, the current results could provide guidelines for lightweight PV module design (with a weight of 4.8 kg/m2) in the thermo-mechanical aspect. This research sheds light on the potential of lightweight modules specifically for VIPV applications. 1. Introduction
Adopted encapsulants have a significant impact on module efficiency, stability, and reliability. In addition, to ensure the unchanged performance of PV modules in time, the encapsulant materials must be selected properly.
The increased weight can cause deflection of photovoltaic (PV) module, which may lead to decreased cell efficiency. In this study, we developed a deep neural network (DNN)-based finite element (FE) surrogate model to obtain the optimal frame design factors that can improve deflection in large-scale bifacial PV module.
The encapsulant polymer-based materials in PV modules must provide proven mechanical stability, electrical safety, and protection of the cells and other module components from environmental impacts.
Schematic buildup of a lightweight module with reinforced encapsulant. Here, we replace the front glass with a polymer frontsheet, and provide additional strength by thickening and incorporating glass fibres (GF) into the encapsulant during the lamination of the laminate. This results in a total thickness slightly below 5 mm.
