Energy Yield of Solar Panels in the System of their Position Control

Abstract:

The contribution deals with the climatic conditions in which a solar rotatable structure with flat solar panels was placed on the roof of the building in which the Department of Process Technique is located. There was designed a control system of the structure in order to achieve an increase in efficiency of solar panels. Presented are three ways of the rotatable structure positioning. During the first measurements, the data were obtained and recorded with a fixed position of the solar panels, the second measurements were carried out while the solar panels were rotating along the ecliptic without being dependent on the actual value of the solar radiation intensity, while with the third measurements the rotation was initiated depending on the intensity of the incident solar radiation on the collectors surface. The archived data obtained from individual measurements are presented in the graphs which show the advantage of solar panels rotation in terms of achieving higher temperatures of a solar fluid and a heat transfer medium of an accumulation tank.
