“…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]. The findings that both the highest yield and loss, due to temperature, are linked with bi monocrystalline modules while poly-Si modules generally showed higher yield du combination of temperature effect and soiling effect on the samples.…”

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.

“…On one hand, the level of radiation received by 90° modules was lower than that in the other tilt angles, which resulted in low current and less overheating (Figs 2 and 3). And, on the other hand, the modules in this angle had better ventilation [6]. We estimated the average monthly soiling loss by assessing the tc-PR increase after each cleaning event using the calculated tc-PR.…”

“…Some research groups have studied how soiling affects the energy yield and efficiency of different types of modules in arid climates. One of these groups carried out 1-year monitoring of six types of PV technologies: monofacial and bifacial monocrystalline silicon, polycrystalline silicon, glass-glass poly-Si, copper indium gallium selenide (CIGS), and cadmium telluride (CdTe) modules [6]. They installed the modules in a desert site, facing south, and with three different tilt angles (5°, 25°, and 90°), and found that the modules with 25° tilt had median monthly soiling losses between 2.76% and 6.15% and the modules with 5° tilt had losses between 5.09% and 8.15%.…”

This paper assesses the performance of photovoltaic (PV) technologies integrated into buildings in the desert climate and the factors that affect energy yield. Cadmium telluride (CdTe) and standard monocrystalline silicon (c-Si) modules were installed facing south, in the three more common tilt angles used in the Building Applied Photovoltaics (BAPV) and Building Integrated Photovoltaics (BIPV) applications at the Dubai latitude (90°, 25°, and 0°). We monitored the energy production, the temperature of the PV modules, irradiance on each tilt angle, and the meteorological parameters for a full year. We then calculated the performance ratio for the six modules to evaluate the different factors, including temperature and soiling losses, following IEC 61724-1. The 25° modules, usual PV rooftop angle, had the highest and more consistent energy yield throughout the year. Conversely, the energy yield of the 90° modules, typical angle for facades, vertical shading devices, and guardrails, had the lowest yield and showed wide variations. This is expected as the 90° angle is more affected by the seasonal changes of the solar altitude. The soiling losses on these modules were lower than 1%. However, at 0°, the soiling loss was more evident, with an average reduction of 10.79%. The c-Si module at 25° generated the highest normalized energy yield of 402.02 kW h/m 2 , which was 23.5% more than that of CdTe module with the same tilt angle.

“…Ventilation is an essential component in BIPV, especially in countries with hot climate conditions. A retrofit case study in Madrid [5] observed a nominal PV temperature difference of 12°C between naturally ventilated and non-ventilated crystalline silicon (c-Si) BIPV façades, which has resulted in an improvement of 2.5% of its efficiency. An experimentalnumerical study in Azmir found that the assessed the performance of a c-Si PV façade showed that natural ventilation increased the electricity output by about 2% yearly [6].…”

“…To determine the performance of different PV technologies in arid climates, researchers from the DEWA R&D Center carried out a study to assess six types of PV modules in three different tilt angles, 5°, 25°, and 90° [5]. The bifacial monocrystalline modules showed the highest normalized yield in comparison with conventional poly-Si and mono-Si modules, glass-glass poly-Si, and CIGS and CdTe thin-film modules.…”

This paper presents a test and validation research on the energy performance of photovoltaic solutions integrated as opaque, ventilated façades in the harsh desert climate of Dubai, UAE. We have assessed the performance of copper indium gallium selenide (CIGS) and monocrystalline silicon (c-Si) modules in the three most suitable orientations for Dubai's buildings (south, east, and west), over one full year. Additionally, we investigated the effect of modules' temperature on the energy yield. The normalized energy yield of c-Si modules was continuously higher than the CIGS modules, across all orientations, with an average annual difference of 13.6%. Throughout the whole period, the south-oriented modules produced more energy than those in the east and west. During the period from October to February, they produced up to 48.5% more than the other orientations. The east and west façades, on the other hand, produced up to 40.9% more energy than the south in the period from April to August. Furthermore, although the annual irradiance on the west was only 1.7% lower than the east, the annual production of the west modules was more than 12% less. These modules start to receive direct solar irradiation in the afternoon when ambient temperatures reach their highest values, and after they accumulated heat during the morning.
