“…Essentially, the performance of a PV system is defined by its ability to generate electricity by converting sunlight energy within a specific period compared to the system's power output rate under laboratory or standard test conditions (STC) [9]. The STC represents conditions with an irradiance of 1000 W/m2, panel temperature of 25 °C, and air mass of 1.5 (AM1.5) [10]. In operational conditions, the power loss of a PV system is attributed to natural factors and the specifications of the PV cell (such as the temperature coefficient, inverter clipping, string faults, and power factor).…”

Floating solar photovoltaics (FPV) are increasingly favored for solar energy harnessing, necessitating a thorough grasp of performance-influencing factors, notably weather conditions. This study delves into the statistical scrutiny of humidity’s impact on FPV performance within tropical settings, focusing on Jakarta’s urban context. While humidity’s effect on solar cell performance, particularly voltage output, is acknowledged, its influence in urban pond settings remains underexplored. Thus, an experiment was conducted, placing a floating PV system over a 24 m2 pond to directly assess humidity’s impact. Additionally, ambient temperature and irradiance levels were analyzed to comprehensively understand their interconnected effects on system efficiency. Moreover, the study investigated airflow’s role in humidity variation and overall environmental dynamics. The experimental setup comprised two strategically positioned solar panels over a 1.5-meter-deep pond. Regression and analysis of variance (ANOVA) techniques were employed to scrutinize humidity’s impact on the FPV system. Results revealed an inverse relationship between humidity and voltage, with humidity also contributing to ambient temperature reduction, thereby enhancing the microclimate. These findings underscore the intricate interplay of factors, where humidity, driven by evaporation, negatively influences irradiance levels while indirectly benefiting PV cell temperature by lowering ambient temperature. This research provides crucial insights for optimizing FPV performance in tropical urban settings, emphasizing the importance of nuanced approaches that account for humidity’s impact on floating photovoltaic systems.

“…IEC-61215-2016 is limited to flat plate modules, specifically c-Si and thin-film technologies. Within the 18 Module Quality Tests outlined in IEC-61215, only five modules tests (MTs) are applicable for assessing the passing standards of PV modules under hot and humid conditions [75]. IEC-62804 states that the PID test standard calls for negative 1000 V to be applied to the short-circuited terminal of module for 96 h at 85 • C and 85% humidity.…”

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.
