Managing Spatial Orientation of Photovoltaic Module to Obtain the Maximum of Electric Power Generation at Preset Point of Time.

To evaluate the possibility of obtaining the maximum of electric power generation at a preset point of time by varying the spatial orientation of photovoltaic modules, its effect on the amount of utilized solar radiation was studied. The experiment was conducted by the example of Zernograd, Rostov oblast, Russia, with specially designed research equipment. The analysis of input of solar radiation to surfaces with different spatial orientation revealed that, owing to different combinations of spatial placement of the receiving site with respect to cardinal directions and the horizon line, it is possible to shift the maximum of power takeoff with photovoltaic modules relative to midday to the morning and evening time about by 4.5 h.
