Geometric method for assessing the shadowing of objects in solar power engineering

This paper describes a geometric model for assessing the effective area of solar panels with regard to their shadowing when the object is illuminated by the solar flow from a given direction. Using energy methods, the flow density, the irradiation created by it, and the exposure in radiant or effect...

description This paper describes a geometric model for assessing the effective area of solar panels with regard to their shadowing when the object is illuminated by the solar flow from a given direction. Using energy methods, the flow density, the irradiation created by it, and the exposure in radiant or effective units of measurement were determined. Both physical and mathematical formulation of the problem of assessing the energy efficiency of solar panels using the method of geometric modeling are described. To evaluate energy efficiency, a voxel geometric model was selected that discretizes the computational space. A significant difference in the developed voxel geometric model is that it is multivalued, i.e. uses not a 2-digit, but a 4-digit code. Such ambiguity allows the decisive algorithm to quickly “figure out” the origin of the shadow source when calculating the total effective area of solar panels. The described software implementation of the geometric model, graphical shell, and model verification results can be used in the optimization system for designing spacecraft and other solar energy facilities.
