Because the efficiency of a PV module drops as the light hitting its surface is scattered, soiling can cause a significant power loss. The amount of soiling that a panel can withstand without any loss in power production is called the soiling factor. Webloss is 1.298% (less than 1.300% from STC). When arranging the total voltage, average current, and average power from the solar panel test data sorted by highest to lowest value it is found that the total voltage arrangement causes the electrical loss to be 1.297% (this is the only value is lower than the loss from the resistance of the open toshiba laptop

WebThe soiling loss that is applied is equal to the value given in the system loss settings (or values, if given monthly). Snow This is the loss in irradiance due to snow covering the modules. The snow ... the effect can change the power output of a module relative to its STC rating, it is typically modeled as a fixed loss factor. Soiling is typically caused by the deposition of airborne particles, including, but not limited to, mineral dust (silica, metal oxides, salts), pollen, and soot. However, soiling also includes snow, ice, frost, various kinds of industry pollution, sulfuric acid particulates, bird droppings, falling leaves, agricultural feed dust, and the growth of algae, moss, fungi, lichen, or biofilms of bacteria. Which of these soiling mechanisms are most prominent depends on the location.
