Investigation of orientation impact on electrical power of bifacial solar elements

Purpose To develop the integrated mathematical model for definition of bifacial solar element rational power operation in the various operation conditions caused by orientation of solar panels and power influence. Methodology. We have proposed the method of definition of bifacial solar elements irradiation and temperature mode and also electric power production at various orientation of panels. Results. We have made analytical investigations of temperature operation conditions of solar elements and their influence on electrical power for various panels orientation in space. Features of irradiation of the forward and back parts of solar panels, conditions of a temperature operating mode and its influence on electric power production are shown. Possibilities of rational conditions of spatial panels orientation are considered. Originality. We have suggested and proved the model of definition bifacial irradiation solar panels and thermal conditions of electric power production and also rational conditions of spatial orientation of panels. Practical value. The developed by us methodology as well as results of its application, allows to choose rational architecture of a solar power station with high efficiency.
