The objective of the paper is the assessment of the wind load applied to a real photovoltaic (PV) platform installed on a site situated in Brasov, which belongs to the Transilvania University. The platform has a double-tracking axis mechanism which allows the rotation of the platform disk depending on the sun position, in order to gather the maximum solar yield to produce electricity. The study was performed by numerical simulation using COMSOL Multiphysics, a finite element method based computer code, using a common solver for the study of several problems that require resolution of partial differential equation systems. The simulation results are outlined in the form of pressure distribution graphs over the platform disk. The model we created can be used in the case when a more complete study of wind effects on the platform for other incident directions is needed, allowing numerical modelling of air flow around the platform, as well as pressure distributions on it to be computed accurately.
