Due to the current energy crisis in Brazil and in the world, it is important to explore renewable energy sources, such as photovoltaic systems. Considering this, this research analyzes a responsive capture system called Girassol, which seeks better efficiency in energy production. Tests were performed on the mechanism to assess the advantages and disadvantages of using the solar tracker compared to fixed systems. The tests were carried out using the physical prototype and computational tools to compare the results. The methodology used was Design Science Research, which has to develop and improve affordable solutions, based on experiments and computational simulations. Compared to the physical prototype it was possible observe that there is a greater energy upgrade of the Girassol mainly in the initial and final moments of the daylight hours.
