The effect of dust on solar photovoltaic systems
Soiling is the accumulation of dust on solar panels that causes a decrease in optical efficiencies of CSP systems. However, geographically widespread data is only available for solar photovoltaic (PV) systems. The changes in efficiency of a large commercial site (86.4 kWdc) was quantified during the summer dry period over the course of 2010 with respect to rain events observed at a nearby weath...
متن کاملDust Measurements in the Outer Solar System
Dust measurements in the outer solar system are reviewed. Only the plasma wave instrument on board Voyagers 1 and 2 recorded impacts in the Edgeworth-Kuiper belt (EKB). Pioneers 10 and 11 measured a constant dust flux of 10micron-sized particles out to 20 AU. Dust detectors on board Ulysses and Galileo uniquely identified micron-sized interstellar grains passing through the planetary system. Im...
متن کاملInterstellar Dust in the Solar System
The Ulysses spacecraft has been orbiting the Sun on a highly inclined ellipse almost perpendicular to the ecliptic plane (inclination 79◦, perihelion distance 1.3 AU, aphelion distance 5.4 AU) since it encountered Jupiter in 1992. The in-situ dust detector on board continuously measured interstellar dust grains with masses up to 10−13 kg, penetrating deep into the solar system. The flow directi...
متن کاملSeasonal variations of the solar radiation scattered from the putative dust rings of Mars: a possible basis for photometric searches
The continuous bombardment of the Martian moonlets Phobos and Deimos by the interplanetary flux of micrometeoroids is believed to produce ejecta, a part of which could be introduced on long-lived circummartian orbits and form tenuous dust rings around the planet. This view is supported by a number of theoretical studies which yield a detailed space structure of the dust rings. There is, however...
متن کاملA study on solar dust ring formation based on fractal dust models
Using the fractal aggregate model for circumsolar dust grains, the nature of the circumsolar dust clouds is examined. As a fractal dimension of the aggregate decreases, the porosity of the aggregate increases. Consequently, its temperature becomes independent of its size, and approaches that of its constituent particles. This evidence suggests that the fractal aggregates with different sizes an...
