“…It was observed during the last three years that many old PV modules affected by hotspots, most frequently, are affected by microcracks. In contrast with [111] results, it was observed by [118][119][120][121] that the hotspots' temperature distribution was strongly dependent on various conditions including (1) the integration of the MPPT, (2) day-to-night temperature variations, (3) day-to-night irradiance variations, and, most importantly, (4) the amount of partial shading affecting the hotspotted PV modules.…”

Solar photovoltaic (PV) energy has shown significant expansion on the installed capacity over the last years. Most of its power systems are installed on rooftops, integrated into buildings. Considering the fast development of PV plants, it has becoming even more critical to understand the performance and reliability of such systems. One of the most common problems faced in PV plants occurs when solar cells receive non-uniform irradiance or partially shaded. The consequences of shading generally are prevented by bypass diodes. A significant number of studies and technical reports have been published as of today, based on extensive experience from research and field feedbacks. However, such material has not been cataloged or analyzed from a perspective of the technological evolution of bypass diodes devices. This paper presents a comprehensive review and highlights recent advances, ongoing research, and prospects, as reported in the literature, on bypass diode application on photovoltaic modules. First, it outlines the shading effect and hotspot problem on PV modules. Following, it explains bypass diodes’ working principle, as well as discusses how such devices can impact power output and PV modules’ reliability. Then, it gives a thorough review of recently published research, as well as the state of the art in the field. In conclusion, it makes a discussion on the overview and challenges to bypass diode as a mitigation technique.

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.

“…In order to address this issue, scholars have made much effort before particularly in the field of the condition monitoring of solar PV panels. The recent efforts and advances on PV panel condition monitoring have been reported in detail by several recently published review papers, such as Daliento et al (2017), García et al (2022), Kandeal et al (2021a), Herraiz et al (2020), and Ramirez et al (2022). To keep a concise context of the paper, herein it is not necessary to repeat the detailed description of all of these techniques.…”

“…More details can be found from Toledo et al (2019). The practice has shown that the IRT is effective in condition monitoring PV panels, especially in detecting those incipient faults that are difficult to find from the appearance (Herraiz et al, 2020). Another advantage of using the IRT is that the infrared thermal images of all PV panels in a solar power plant can be quickly and easily obtained with the aid of drones or other type unmanned products (Tsanakas et al, 2016).…”
