Abstract
This paper aim to analyze the exerted pressions by the wind on photovoltaic panels installed on rooftops as well as perform analysis of tensions and deformations of supporting aluminum structures for photovoltaic panels. Computational simulations are performed in order to save time and obtaining them best solution. The wind intensity and directions exert pressures on the photovoltaic installation and its support structure resulting on the concentration of tensions on the fixing points on both structural components and roof’s attachment points.
