“…The degradation of PV modules can be categorized into four major categories, i) degradation of packaging material, ii) loss of adhesion, iii) degradation of module interconnects, and iv) degradation of the solar cell material (Sinha et al, 2020). Some of these degradations lead to visible changes in the module and can be detected by visual inspection of the module without doing any electrical characterization of the module (Meena et al, 2022). The images of the various visual degradations observed in our investigation are given in Figure 2, which are inline with other visual degradation studies in literature (Menoufi et al, 2017;Ingenhoven et al, 2019;Tanesab et al, 2020;Meena et al, 2022).…”

This study evaluates the degradation of mono, poly, and thin-film silicon solar photovoltaic (PV) modules through visual and electrical measurements in Dhaka’s tropical wet and dry climate conditions. For this, several sites of rooftop solar PV installations in Dhaka, aged at least 5 years, were selected for field investigation. A visible inspection for visual degradation followed by experimental testing on various electrical characteristics of the PV modules installed on the rooftop using a portable Seaward I–V Tracer for measuring the electrical degradation was done. The electrical data were used to evaluate the degradation of short circuit current, open circuit voltage, fill factor, and maximum power in the field as compared to the nameplate values. Experimental results showed the varying types of visual degradation types such as visible cracks, snail trails, moisture intrusion, front glass, and discoloration for the investigated PV modules. The degradation of PV modules in terms of short circuit current was 0.7%/year for 85Wp mono c-Si, 7.6%/year for 150Wp poly c-Si, and 9.7%/year for 105Wp silicon thin-film, respectively. We believe this study would guide the maintenance of the solar PV systems installed on Dhaka city’s rooftop buildings.

“…However, several of the degradation was specific to field-aged modules, such as junction box breakdown and busbar delamination. The maximum loss was observed in FF for modules subjected to the DH and TC tests, while the maximum loss was observed in I sc for accelerated aged modules subjected to the HF test [88]. In a study, it was observed that the moisture ingress had not achieved a steady state, even after 1000 h of accelerated test (followed by usual IEC standard) exposure [10].…”

Solar photovoltaic (SPV) systems installed on water bodies, i.e., floating solar PV (FSPV) and canal top solar PV (CTSPV), have gained significant propulsion in recent years, not only because of their enormous potential but also because of other additional co-benefits. This review article discusses the scope and potential of FSPV and CTSPV, an ambitious plan, and various upcoming FSPV projects in India. The review focuses on different degradation modes, failure mechanisms, characterization techniques and distinct factors influencing the degradation of SPVs operating in tropical climates. It was explored that potential induced degradation (PID) and materialistic degradation have a significant impact on the performance of SPV. The paper provides an overview of the test procedures outlined in IEC-61215 and IEC-62804 that pertain to SPV performance under hot and humid conditions. Additionally, it presents a comprehensive review of the various methodologies adopted for accelerated damp heat testing to predict the life of PV systems in such conditions, and their significant analytical and visual outcomes is elucidated. Also, till date, no simulation tool has been available to assess the long-term performance of SPV in a humid environment. As this energy generation technique is still in its infancy, this study will help many researchers and solar power developers recognize the impact of elevated and prolonged exposure to temperature and humidity on generation, degradation, and mode of failure for different SPV technologies.

“…However, the information provided by the manufacturers only allows an approximate sizing of the PV system. One of the major problems with PV systems is the degradation of PV modules when exposed to natural outdoor conditions [6][7][8]. PV module degradation is highly dependent on climate, but also on harsh environmental parameters, PV technology, exposure period, installation method, solar tracking system, solar radiation concentration mechanism, and the PV system voltage [9].…”

This study presents the measured data of the "Oued Keberit" PV plant over a period of four months (January to April 2022) after nearly 6 years of outdoor exposure to the climate of Souk Ahras, eastern Algeria, in order to evaluate the performance of the solar PV system. This evaluation includes the calculation of PV system performance variables such as module performance, final performance and performance of the module references, system losses, photovoltaic friendly efficiency, system efficiency, performance ratio and capacity factor based on measured data, allowing comparison of actual PV system performance and reference values determined by manifacturers. The results showed that the four-month average values of the parameters Eac, Yr, Yf, PR, h, CF are 1.06375125MWh, 4.08h, 4.25h, 1.06, 16.40%, 60.28% respectively. Also, the high efficiency of the photovoltaic system was obtained during winter, due to the low temperature and the sufficient amount of solar radiation. However, the photovoltaic system generates a lot of energy during summer, although there is less output than during the winter season. This is because summer has maximum values for sunshine duration and solar radiation.
