“…The efficiency of these PV systems decreases drastically when the crystalline structure of the modules is damaged by climatic conditions such as the wind [4]. PV systems often require careful structural considerations, especially when mounted on building rooftops where module racking systems and anchoring into the roof structure is required.…”

An investigative study was performed on the Shangri-La Hotel in Toronto in order to determine the impact of local wind conditions on the glass balcony guard failures seen in Toronto in the last five years. An accurate CFD simulation model was developed for external flow applications through a wind tunnel validation study. The simulation was used to analyze average wind conditions and extreme (gust) wind conditions at the balcony guard failure locations, as well as identify potential areas of concern on the Shangri-La Hotel. A strong correlation between failure location and common wind conditions was established, however it was concluded that wind loading was likely not the primary cause of failure.

“…Authors observed that 50% of cracks are parallel to the busbar, whereas diagonal, dendritic and several direction cracks are responsible of around 15% of the cracks. Kilikevičius et al [86] studied the effects of dynamic loads, such as vibrations or wind, on the performance and crack apparition of PV modules. They achieved that the maximum fracture occurred at 16 Hz, with a maximum amplitude of 7mm at 20 Hz.…”

The sustainability of the global energy production systems involves new renewable energies and the improvement of the existing ones. Photovoltaic industry is growing thanks to the development of new technologies that increase the performance of photovoltaic systems. These systems are commonly subject to harsh environmental conditions that decrease their energy production and efficiency. In addition, current photovoltaic technologies are more sophisticated, and the size of photovoltaics solar plants is growing. Under this framework, research on failures and degradation mechanisms, together with the improvement of maintenance management, becomes essential to increase the performance, efficiency, reliability, availability, safety, and profitability of these systems. To assess maintenance needs, this paper presents a double contribution: an exhaustive literature review and updated survey on maintenance of photovoltaic plants, and a novel analysis of the current state and a discussion of the future trends and challenges in this field. An analysis of the main faults and degradation mechanisms is done, including the causes, effects, and the main techniques to detect, prevent and mitigate them.

“…The PV panels are subjected to static as well as dynamic loads in the field [51], but the IEC 61215 test [50] only covers static load conditions [25,47]. The studies [52,53] recommended to consider static as well as dynamic characteristics of PV modules. Therefore, dynamic loads are also considered in present study to simulate their effects.…”

Thermo-mechanical loads induce stresses in photovoltaic (PV) modules, leading to crack formation.In this context, the understanding of module's thermo-mechanical behavior is important. To investigate the thermo-mechanical behavior of smart wire connected technology (SWCT) and busbar PV modules throughout their entire life, the present study is conducted that probes the stress distribution and deformation during production, transportation, and subsequent mechanical and thermal loading stages in a consecutive step-by-step manner using finite element modelling approach.Pre-stresses and non-linearities are considered in simulation models. Stresses and displacements experienced by different parts/layers are examined, and crack sensitive regions are identified. In addition, the SWCT and busbar modules are compared, and it is found that SWCT interconnection is relatively a less stress inducing process and less susceptible to thermal and dynamic affects. During production stage, stresses of 39.3 MPa and 40.4 MPa are generated in SWCT cells and copper wires ACCEPTED MANUSCRIPT 2 respectively; while, stresses of 60 MPa and 87 MPa are generated in busbar cells and busbar respectively. Similarly, lower stresses are induced in SWCT PV modules during subsequent stages.The comparison results show advantages of SWCT module in terms of mechanical stability which can lead to improve the performance and reliability of PV modules.
