Varying spatial orientation of photoelectric panels as method of managing graph of electric energy generation

Abstract

One of the main issues in the determining layout of photovoltaic installations is choosing optimal parameters for photovoltaic panels and auxiliary equipment and duplicating energy sources, which makes it possible to justify economically the electrical energy generation. Regularity of solar radiation variation for the studied geographical point throughout the year, and the influence of atmospheric phenomena, as well as the dynamics of daily and seasonal electrical energy consumption must be considered, which will help to predict the operation mode of the plant, and match generation and consumption schedules. Variation of tilt angle of the photovoltaic module receiving surface relatively to horizon and cardinal points makes it possible to manage the schedule of power generation at solar plant and to match it with the load curve, due to the maximum possible convergence of them, as change in the spatial orientation of the photovoltaic panel surface makes it possible to shift the maximum of solar radiation flux in time. The results of the experimental research also revealed the dependence of the current produced by the photoelectric panel on its spatial orientation due to the change of the incoming solar radiation flux on it.
