The research aims to identify and evaluate the availability of solar energy in the four seasons of the year as a function of the different inclinations and orientations of the roofs of urban buildings in the city of Cascavel - PR, determining the variability of the solar energy incident on the surfaces studied. The work was carried out considering three types of roof coverings (ceramic, fiber cement and metal), the corresponding slope at which they should be installed and the cardinal direction. The four seasons were also taken into account to determine seasonal variations. Daily solar radiation data for Cascavel was used to determine the solar energy available on each roof according to slope and cardinal orientation. The results determined the effect of roof inclinations and orientations on the availability of solar energy incident on the roof surface, with the aim of using this energy for photovoltaic generation. The main considerations led to the conclusion that the most effective arrangement of solar panels is one that maximizes efficiency while maintaining an affordable cost. This is achieved through the most suitable installation, with a North orientation being preferable, followed by West, East and South. The choice is also influenced by the slope of the roof, where ceramic roofs result in greater energy generation when facing north, compared to metal or fiber cement roofs. However, for other directions, metal and fiber cement materials outperform ceramic due to the smaller reduction in productivity throughout the day.
