“…Researchers carried out a study to determine the influence of dust in the aggravated environment of the Greek capital, Athens, and considered that the dust effects are site-specific (Kaldellis and Kokala 2010). Similarly some researchers carried out fundamental studies on dust fouling effects on PV module glass cover (Said and Walwil 2014).…”

In the present study, a detailed investigation on air dust particles effect on photovoltaic (PV) model performance has been carried out. The scanning electron microscope analysis of the collected dust samples was being carried out, and the obtained images were being analyzed in order to observe the character and topography of the dust sample particles. The data for dust samples of different weights with change in power loss in a PV module at three solar irradiations levels of 650, 750 and 850 W/m 2 have been collected. In present study, the effect of environmental dust particles on power loss in PV module has been evaluated by measuring the electrical performance index such as voltage, current and power. The minimum power value of 3.88 W has been observed during the accumulation of rice husk on PV module.

“…The reasons for a lack of cleaning in these types of projects are that the PV modules are not accessible to the villagers and there is no formal maintenance program (Ismail et al, 2012). Kaldellis and Kokala (2010) estimate the income loss associated with not cleaning panels to be almost 40 €/kWp (US$ 42.44) on an annual basis. Solar farm owners pay a maintenance cost for cleaning panels in order to prevent the losses due to power degradation and maximise income.…”

The contribution of dust to performance degradation of PV modules in a temperate climate zone

This research investigates the contribution of dust to the long-term performance degradation of various photovoltaic (PV) modules that have been operating for almost eighteen years without any cleaning procedures at the Renewable Energy Outdoor Testing Area (ROTA), Murdoch University, Perth, Australia. A solar module analyser was used to assess the PVs'electrical performance, while a combination of spectrophotometer, scanning electron microscope, electron dispersive spectroscope and X-ray diffraction were used to exam the properties of the dust on the panels. The study found that the degradation of the PV modules' power output, ranged from 19% to 33%. The degradation is mostly due to non-dust related factors such as corrosion, delamination, and discoloration, which account about 71% to 84%, although the contribution of dust is still significant at 16% to 29%. Anova analysis shows that the dust has a fairly uniform impact on the performance degradation of all PV technologies at ROTA. This is in line with the results of spectral transmittance curves for different dust density samples that essentially flat over the wavelength range of the PV modules. An investigation of the properties of dust revealed that dust particles deposited on PV modules' surface at ROTA were dominated by fine particles built of large amounts of quartz (SiO 2 ), followed by calcium oxide (CaO) and some minors of feldspars minerals (KAlSi 3 O 8 ), which are the main factors in transmittance losses that affect PV module performance.

“…Selecting the correct components is of fundamental importance to a PV panel, keeping in mind the numerous internationally accepted standards. The assumed components of the PV panel are summarized in Table 3. -Air pollutant parameters, PM10 (dust accumulation on the PV panels' surface) Although solar radiation is the most important parameter affecting the output of the PV panel, there are other parameters that affect energy production [56][57][58][59][60]. Some of the major parameters include cell temperature (≤10%), angle of incidence (≤10%), spectral distribution (≤3%), uncertainty in the manufacturer's ratings (≤5% or more), ageing (≤5% over lifetime), mismatch losses (≤2%), losses due to blocking of diodes and wiring (≤3%) [56][57][58], and dust deposition on the solar panels (≤5%) [59].…”

This paper addresses an economic study of the installation of photovoltaic (PV) solar panels for residential power generation in Santiago, Chile, based on the different parameters of a PV system, such as efficiency. As a performance indicator, the Levelized Cost of Energy (LCOE) was used, which indicates the benefit of the facility vs. the current cost of electrical energy. In addition, due to a high level of airborne dusts typically associated with PM10, the effect of the dust deposition on PV panels' surfaces and the effect on panel performance are examined. Two different scenarios are analyzed: on-grid PV plants and off-grid PV plants.
