A significant issue for both researchers and stakeholders within the photovoltaic industry is the use of solar tracker systems to gain the most efficient degree of solar irradiance, by following the movement of the sun. This paper introduces a complete view of the main parts of solar photovoltaic technology, focusing primarily on structural and geotechnical aspects. Firstly, it examines the role of geotechnical engineering, from the selection of an appropriate site to the properties of its soil layers and the establishment of secure foundations. Secondly, it introduces the most important factors related to the structural analysis of solar trackers (i.e. stability and reliability) to maintain the safety and performance of solar photovoltaic systems. The study considers the importance of geotechnical analysis to obtain optimal gains from solar irradiance. Moreover, it discusses the need for appropriate structural analysis to maintain optimal solar irradiance, as well as ensuring the safety of solar tracker systems in relation to their aerodynamic loads. It is found that proper geotechnical investigations to establish the presence of adequate soils with a high bearing capacity and low degree of settlement are vital for the selection of optimal sites for solar tracker systems.
