EN The work presents the design and the physical construction of a test stand consisting of a two-axis tracking installation with astronomical positioning and a fixed structure with the specific surface inclination angle (determined through the power efficiency optimization process) and the azimuth angle. On the basis of the analyses as well as the model tests performed, the control type and the components, such as: the power inverter, monitoring devices, and external radiation power density sensors were selected. The system makes it possible to perform measurements of electric energy generation throughout the year and to estimate the efficiency of the tracking structures used in the conditions specific to the city of Poznań in Wielkopolska.
