“…It is noteworthy that the experiments were focused on the hottest three-hour interval, where temperature effects are highest [4]. This is also verified by previous studies where this particular interval corresponded to simultaneously the peak temperature, peak PV power, and peak energy demand in Qatar [4].…”

“…In this study, a mono-crystalline panel setup was used, which was available in the research facilities. Nevertheless, similar or even more pronounced results could be expected if poly or amorphous PV cells were used, because it was seen in another study that polycrystalline solar cells are more prone to temperature effects than mono-crystalline [4]. Overall, cooling by water has several advantages, such as collecting more irradiance due to refraction through water, dropping the panel temperature, removing light pollutants from the surface, and providing hot water.…”

“…Consequently, the proposed method avoided the appearance of hot spots, because it cooled the panel uniformly on both sides. Further data about the panel monitoring system and climatic conditions of Qatar can be found in a previously-published article [4]. It is noteworthy that the experiments were focused on the hottest three-hour interval, where temperature effects are highest [4].…”

“…Quantitatively, due to the heating effect, the efficiency drops by 0.1%-0.5% for each 1 • C gained by the cell surface, depending on the manufacturing technology [2,3]. In Qatar, during the summer season, the surface temperature of the PV panel reached around 80 • C, which could be the same case for the Arabian Gulf and other Middle East countries [4].…”

The abundance of solar energy is a blessing in the Arabian Peninsula, where more than 2000 kWh/m 2 density has been recorded annually. This has resulted in sincere consideration of PV harvesting in the energy matrix and smart grid. However, artefacts such as degradation of PV efficiency due to the high temperature effect have to be addressed. This paper presents a novel design of a PV cooling system using water to mitigate the effect of high temperature. Several experiments have been conducted, and the results have been analyzed. It has been found that the collected water from the panel after 40 min of cooling gained a temperature of 10 • C approximately, during December 2016. Eventually, the efficiency was improved by 10.35% (without using MPPT) using water at ambient temperature (24 • C) compared to the non-cooled panel. Moreover, the temperature of the panel during solar peak hours dropped from 64.3 • C to 32 • C and from 59 • C to 27 • C in 3 min for the back and front surface, respectively. These results, which are the first of their kind in Qatar, constitute good incentives and pave the way for further investigation to enhance PV efficiency in harsh environments. This would be of paramount significance, especially for scaling up PV deployment, as is planned in Qatar and GCC countries in their 2030 vision.

“…This type of intervention was not carried out in the installation, so this type of loss could not be evaluated. To do this, it is necessary to compare the performance, in situations where only the sensor is cleaned, with those in which both sensors and PV modules were cleaned [77].…”

Abstract:The starting point of the operation and maintenance tasks in photovoltaic plants is the continuous monitoring and supervision of its components. The great amount of registered data requires a major improvement in the ways this information is processed and analyzed to rapidly detect any potential fault, without incurring additional costs. In this paper, a procedure to perform a detailed graphical supported analysis of the operation of photovoltaic installations, based on inverter data, and using a self-developed application, is presented. The program carries out the automated processing of the registered data, providing their access and visualization by means of color maps. These graphs allow a large volume of data set to be simultaneously represented in a readable way, enabling operation and maintenance operators to quickly detect patterns that would require any type of intervention. As a case study, the operation of a grid-connected photovoltaic plant located in southern Spain was studied during a period of three years. The average daily efficiency values of the PV modules and inverters were in the range of 7.6-14.6%, and 73.5-94% respectively. Moreover, the presence of shadings, as well as the hours and days mainly affected by this issue, was easily detected.
