“…PV corrosion is the damage to the PV modules caused by exposing them to humidity and thermal cycling as a result of altering the temperature between day and night [105] . Also, deterioration due to salty water can occur when solar panels are subjected to salty water or salty mist which can oxidize the metal components and damage their operation and efficiency.…”

“…One of the major reasons for this issue is poor production, installation, or maintenance. The delamination of PV can cause bubbles or pleats on their rear surfaces because of air and water vapor passing through the layers of the PV panels [105] . Consequently, internal corrosion occurs, and the modules′ efficiency and lifespan are reduced.…”

In recent years, floating photovoltaic (FPV) technologies have gained more importance as a key source of clean energy, particularly in the context of providing sustainable energy to buildings. The rise of land scarcity and the need to reduce carbon emissions have made FPV systems a cost‐effective solution for generating electricity. This review article aims to explore the rapidly growing trend of floating PV systems, which can be a practical solution for regions with limited land areas. The article discusses the structure of the PV modules used in FPV plants and key factors that affect site suitability choice. Moreover, the article presents various techniques for cooling and cleaning FPV to keep optimal performance and discusses feasible trends and prospects for the technology. Finally, this paper proposes the potential integration of FPV systems with other technologies to enhance energy generation efficiency and discusses other research aimed at the advancement of the technology. By examining the various features of FPV systems, this review article contributes to understanding the advantages and challenges associated with using this sustainable energy technology in different regional contexts.

“…Similar to corrosion, LID and LeTID have continued to receive special attention lately, due to their frequency and contribution to global PV degradation rates [7]. LID is characterized by a premature and significant loss of cell efficiency during the first hours of light exposure with an energy greater than the material bandgap [93,94].…”

“…Recognized as a cheap and sustainable option, renewables including solar and wind energy technologies provide clean energy options that contribute heavily to the reduction of ecological problems globally, particularly CO2 emission [1][2][3][4][5]. Solar as well as wind technologies are projected to be the major energy source by the year 2025, with solar energy production contributing 60% of the capacity additions [6,7].This projection is highly feasible provided that the reliability, accessibility, and performance issues are continuously monitored and resolved. In recent years, the installation of solar photovoltaic (PV) modules, both at utility-scale and residential roof-top systems, has increased geometrically majorly due to factors which include their well-known affordability, scalability and long-term warranty, and most importantly, the continuous reduction in the levelized cost of electricity (LCOE) of solar PVs worldwide [8][9][10][11].…”

Solar Photovoltaic Modules’ Performance Reliability and Degradation Analysis—A Review

2022

View full text Add to dashboard Cite

The current geometric increase in the global deployment of solar photovoltaic (PV) modules, both at utility-scale and residential roof-top systems, is majorly attributed to its affordability, scalability, long-term warranty and, most importantly, the continuous reduction in the levelized cost of electricity (LCOE) of solar PV in numerous countries. In addition, PV deployment is expected to continue this growth trend as energy portfolio globally shifts towards cleaner energy technologies. However, irrespective of the PV module type/material and component technology, the modules are exposed to a wide range of environmental conditions during outdoor deployment. Oftentimes, these environmental conditions are extreme for the modules and subject them to harsh chemical, photo-chemical and thermo-mechanical stress. Asides from manufacturing defects, these conditions contribute immensely to PV module’s aging rate, defects and degradation. Therefore, in recent times, there has been various investigations into PV reliability and degradation mechanisms. These studies do not only provide insight on how PV module’s performance degrades over time, but more importantly, they serve as meaningful input information for future developments in PV technologies, as well as performance prediction for better financial modelling. In view of this, prompt and efficient detection and classification of degradation modes and mechanisms due to manufacturing imperfections and field conditions are of great importance towards minimizing potential failure and associated risks. In the literature, several methods, ranging from visual inspection, electrical parameter measurements (EPM), imaging methods, and most recently data-driven techniques have been proposed and utilized to measure or characterize PV module degradation signatures and mechanisms/pathways. In this paper, we present a critical review of recent studies whereby solar PV systems performance reliability and degradation were analyzed. The aim is to make cogent contributions to the state-of-the-art, identify various critical issues and propose thoughtful ideas for future studies particularly in the area of data-driven analytics. In contrast with statistical and visual inspection approaches that tend to be time consuming and require huge human expertise, data-driven analytic methods including machine learning (ML) and deep learning (DL) models have impressive computational capacities to process voluminous data, with vast features, with reduced computation time. Thus, they can be deployed for assessing module performance in laboratories, manufacturing, and field deployments. With the huge size of PV modules’ installations especially in utility scale systems, coupled with the voluminous datasets generated in terms of EPM and imaging data features, ML and DL can learn irregular patterns and make conclusions in the prediction, diagnosis and classification of PV degradation signatures, with reduced computation time. Analysis and comparison of different models proposed for solar PV degradation are critically reviewed, in terms of the methodologies, characterization techniques, datasets, feature extraction mechanisms, accelerated testing procedures and classification procedures. Finally, we briefly highlight research gaps and summarize some recommendations for the future studies.
