“…Considering the impact of PV technologies, assessment of the performan different roof mounted PV systems in Abu Dhabi was carried out [50], and it was f that poly-Si types have a higher annual yield than the mono-Si types. The perform degradation of PV modules installed in Dubai for more than two years was investigated [51]. The results suggest that mono-Si PV modules have the lo degradation rate of 0.07%/year, compared to CIGS (3.9%/year) and Poly-Si (2.9%/y An experimental study on six (6) different types of photovoltaic (PV) modules i Dubai climate over a two-year period has also been carried out [44].…”

Sustainability in architecture engages a wide range of considerations in the light of the significant negative impact of buildings on the environment. One aspect of research in this parlance engages the technological and the social dimensions of building innovation, which promote the use of renewable technology as a mitigation strategy. The challenge, however, is that the end-users or building clients do not always have sufficient awareness and information regarding these technologies to guide their decision to accept it. Consequently, the diffusion of said innovations is slow, and the environmental or building problems they were invented to solve persist at the expense of both humanity and the environment. This study, therefore, focuses on a quantitative investigation to ascertain the level of awareness and interest of residents in the United Arab Emirates (UAE) on Building Integrated Photovoltaics (BIPV) as an example of renewable energy-based building technology. In this study, 289 residents participated, following the distribution of a questionnaire to demographically distinct individuals. This distinction was used in the analysis to highlight different groups such as, gender, generations, and occupational background of the respondents. The findings of the study show, firstly, that there is a high level of awareness of BIPV in the sample. The study also shows that comparing awareness with each of these demographic variables produced a second layer of findings. For example, the statistical analysis showed that there is no significant difference between the level of awareness and any of the demographic characteristics of the study participants. However, there is a significant statistical difference (p = 0.000) between awareness and interest in BIPV. In concluding this study, recommendations for further research that elaborates other statistical variables and tests, as well as a follow-up qualitative investigation are planned and outlined for future studies. The findings of this investigation may be of benefit to researchers, policy makers, as well as energy companies and marketing agencies within and outside the region.

“…United States of America (USA): When amorphous silicon (a-Si) modules first became commercially available, the National Renewable Energy Laboratory (NREL) reported degradation rates higher than -1.0%/year [7]. In [8] and [9], similar results of the PV degradation were found in small (<10 kW) size PV installations exhibiting an annual degradation rate of approximately -0.8% to -1.25 %/year.…”

This article presents the degradation rates over eight years for 3000 PV installations distributed across the UK. The study considers three PV cell technologies, namely, monocrystalline silicon (Mono-Si), polycrystalline silicon (Poly-Si), and thin-film Cadmium Telluride (CdTe). The available raw data undergoes three key stages: normalization, filtering, and aggregation, before the degradation analysis of the considered installations. This algorithm can be considered as one of the paper contributions. Results show that a maximum degradation rate of-1.43%/year is observed for the CdTe type, whereas Poly-Si and Mono-Si PVs have annual degradation rates of-0.94% and-0.81% respectively. Moreover, this article exploits the monthly mean performance ratio (PR) for all the examined PV sites. The highest PR value of 87.97% is calculated for the Mono-Si PV installations, while 85.08% and 83.55% is calculated for Poly-Si and CdTe installations, respectively.

“…Therefore, when data shows decrease in the output power, it can be sometimes assumed that the inverter, maximum power point (MPPT) unit 7,8 , or the PV power optimiser 9 is not 100% efficient. (2) To date, the existing PV degradation estimation models such as 10,11 are not very accurate when all the PV-relevant parameters are unavailable. For example, the NREL model 11 requires the input of solar irradiance.…”

As the adoption of renewable energy sources, particularly photovoltaic (PV) solar, has increased, the need for effective inspection and data analytics techniques to detect early-stage defects, faults, and malfunctions has become critical for maintaining the reliability and efficiency of PV systems. In this study, we analysed thermal defects in 3.3 million PV modules located in the UK. Our findings show that 36.5% of all PV modules had thermal defects, with 900,000 displaying single or multiple hotspots and ~250,000 exhibiting heated substrings. We also observed an average temperature increase of 21.7 °C in defective PV modules. Additionally, two PV assets with 19.25 and 8.59% thermal defects were examined for PV degradation, and results revealed a higher degradation rate when more defects are present. These results demonstrate the importance of implementing cost-effective inspection procedures and data analytics platforms to extend the lifetime and improve the performance of PV systems.
