“…Dust deposits on solar panels are known to have a severe detrimental effect on the efficiency of photovoltaic systems (Goossens and Van Kerschaever, 1999;Hamou et al, 2014;Mejia et al, 2014;Rao et al, 2014;Sulaiman et al, 2014;Ilse et al, 2016), with its adverse effects depending on mineral composition and atmospheric conditions (Supplement B).…”

Abstract. Mineral dust is the most abundant aerosol, having a profound impact on the global energy budget. This research continues our previous studies performed on surface soils in the Arabian Peninsula, focusing on the mineralogical, physical and chemical composition of dust deposits from the atmosphere at the Arabian Red Sea coast. For this purpose, aerosols deposited from the atmosphere are collected during 2015 at six sites on the campus of the King Abdullah University of Science and Technology (KAUST) situated on the Red Sea coastal plain of Saudi Arabia and subjected to the same chemical and mineralogical analysis we conducted on soil samples. Frisbee deposition samplers with foam inserts were used to collect dust and other deposits, for the period December 2014 to December 2015. The average deposition rate measured at KAUST for this period was 14 g m −2 per month, with lowest values in winter and increased deposition rates in August to October. The particle size distributions provide assessments of < 10 and < 2.5 µm dust deposition rates, and it is suggested that these represent proxies for PM 10 (coarse) and PM 2.5 (fine) particle size fractions in the dust deposits.X-ray diffraction (XRD) analysis of a subset of samples confirms variable amounts of quartz, feldspars, micas, and halite, with lesser amounts of gypsum, calcite, dolomite, hematite, and amphibole. Freeze-dried samples were resuspended onto the Teflon ® filters for elemental analysis by X-ray fluorescence (XRF), while splits from each sample were analyzed for water-soluble cations and anions by ion chromatography. The dust deposits along the Red Sea coast are considered to be a mixture of dust emissions from local soils and soils imported from distal dust sources. Airborne mineral concentrations are greatest at or close to dust sources, compared to those through medium-and long-range transport. It is not possible to identify the exact origin of deposition samples from the mineralogical and chemical results alone. These aerosol data are the first of their kind from the Red Sea region. They will help assess their potential nutrient input into the Red Sea, as well the impact on human health, industry, and solar panel efficiency. These data will also support dust modeling in this important dust belt source area by better quantifying dust mass balance and optical properties of airborne dust particles.

“…In their experiment, tow PV modules setup on the roof, where one PV was clean and the other one was covered with dust. The performance of the PV modules was analyzed by recording the I-V curves under different solar radiation [15]. The result of this experiment was that the dust deposition on the PV surface does not affect the open circuit voltage of the panels.…”

“…Instead the power loss of the dusted panel which was 5 to 6 % of the maximum power output. Losses recorded on the dusted panel depended on the density of dust deposited on the panel [15]. For example, if the dust surface density is 1.4 g/m 2 then loses of PV power is 5-6 %, while the power loss is between 45-55% if the dust density is 7.1 g/m 2 .…”

Solar energy is a clean energy, environmental friendly, abundant and also free. There are various commercially available forms to capture solar energy such as photovoltaic panels (PV), solar thermal electricity and solar panels. Due to high energy consumption in the buildings and to the laws imposed by European Union to reduce the energy consumption, PVs are ideal solutions for residential houses and commercial buildings in regions with a high solar irradiation levels. This paper presents a case study of the influence of environmental factors (i.e. ambient temperature, snow and dust) the PV performance. The evaluation consists in temperature measurements, infrared (IR) imagines taken with a thermovision camera and visual inspections of PV. Measurements performed on the PV system were recorded during one year period.IR mapping of the heat dissipation in a PV module.

“…Several experimental studies (Appels et al, 2013;Kaldellis and Kapsali, 2011;Kaldellis and Kokala, 2010;Kalogirou et al, 2013;Rao et al, 2014;Zang and Wang, 2011) were devoted to exploring and quantifying the effects of dust deposition in term of power production losses for PV systems and single modules. Dust accumulated on PV panels can vary dramatically according to a number of parameters, such as module tilt angle, exposure time period, climate conditions and dust chemical and physical characteristics, such as composition and particle dimension (Lorenz et al, 2013).…”

Several studies have assessed the influence of soiling deposition on Photovoltaic (PV) modules front-cover with regards to performance losses over time. In fact, soiling phenomena in PV systems are ascribed as responsible for medium and long-term yield reduction up to 16% over the first-year of outdoor exposure. Provided that PV technology is a low yield energy production source, maintaining module initial power output declared values is of the outmost importance to ensure that the return time of investment matches project calculations. The scope of this work was a detailed investigation on self-cleaning coating application as a viable retrofit option on already installed modules, or on newly built PV systems, to avoid soiling build-up on front-covers and guarantee threshold performance level in time. The aim is to provide system designers with a consistent alternative to manual cleaning, without losing effectiveness in terms of yield maintenance. The use of self-cleaning coating instead of acting on panels on a regular basis is more convenient in terms of operation and cost. These issues were analyzed through a set of experiments performed both on commercial size modules and laboratory assembled samples. Results prove product compatibility with PV components and its effectiveness in preventing soiling and dust deposition. Outcomes are presented in terms of maximum power output (P max ) variation according to measurements performed in Standard Test Conditions (STC) at different time steps. In addition, a parallel comparison with uncoated modules exposed to the same outdoor conditions is also proposed to allow for P max variation monitoring performed on a reference sample.
