“…It is reported in other studies that surface erosion evolves with particles impact speed (Sansom et al, 2013;Bouaouadja et al, 2000). To evaluate the effect of this parameter on mirrors erosion phenomenon, we simulate three different impact speed values (Table 3 above).…”

“…Wind speed and wind direction are the most influencing climatic parameters on surface erosion phenomena Sansom et al, 2013;Alhussein, 2010). The wind speed determines the particle's velocity in the air flow according to its properties (shape and density) (Magdich, 2011;Bagnold, 1965).…”

“…The geological parameters pertain to the erosive sand particles properties (size, shape and hardness). These parameters present an important influence on the magnitude and the characteristics of erosion generated upon mirrors surfaces (Caron, 2011;Wang et al, 2010;Sansom et al, 2013;Bagnold, 1965;Sarver et al, 2013).…”

“…This latter is caused either by mechanical contact cleaning or by direct impact of sand particles transported by wind (Zakhidov and Ismanzhanov, 1980;Caron, 2011). The present study will be focused on evaluating the effect of sand particles on mirrors' surface erosion, the phenomenon is inherent to CSP implantation plants sites, very often located in sandy deserts (Wang et al, 2010;Sansom et al, 2013).…”

“…The glass prevents the diffused rays to leave by performing "the greenhouse effect". Fragile glass can be replaced by some polymer film [13]. But the major disadvantage of these materials is the deterioration of their properties under the effect of the ultraviolet rays.…”

This study presents the modeling of a parabolic trough solar collector. The main objective is to show the influences of the parabolic trough sensor effective efficiency (concentrator optical efficiencies of transmission, reflection, geometrical and the receiver absorption coefficient), of its length, of the mass flow rate on temperatures distributions of the heat fluid and the receiver and on thermal global efficiency (solar conversion efficiency into energy usable). The atmospheric parameters are those of Senegal in April. A prototype existing in the CERER (Center of Studies and Research on Renewable Energies) (Dakar-Senegal) is given as example of application.

Sand erosion of solar glass: Specific energy uptake, total transmittance, and module efficiency

et al. 2017

Summary Surface roughness, RZ, normal transmittance, ΤN, total transmittance, ΤT, and photovoltaic (PV) module efficiency, ηS, were measured for commercial solar glass plates and PV test modules identically sandblasted with different loads of quartz sand (200–400 μm), impact inclination angles, and sand particle speed. Measured data are presented versus the specific energy uptake during sand blasting, E (J/m2). Cracks, adhering particles, and scratch‐like textures probably caused by plastic flow phenomena could be observed after sand blasting. Their characteristic size was much smaller than that of sand particles. After blasting and subsequent cleaning, the glass surface was still covered with adhering glass particles. These particles, cracks, and scratch‐like textures could not be removed by cleaning. For sand blasting with α = 30° inclination angle and E = 30 000 J/m2, normal transmittance, total transmittance, and relative module efficiency decreased by 29%, 2% and ∽2%, respectively. This finding indicates that diffusive transmission of light substantially contributes to PV module efficiency and that the module efficiency decrease caused by sand erosion can be better estimated from total than by normal transmittance measurements.
