Abstract: This study designs and sizes several rooftop mounting systems for photovoltaic panels, taking into account the different wind and snow loads that impact these structures across a range of locations. In order to model these photovoltaic panel support structures, made of aluminium or steel, both geographical location and panel tilt angle were incorporated through the engineering software CYPE. The final step was to evaluate the advantages and disadvantages of the various structures designed with different materials and dimensions. Aluminium mounting systems were found to be more resistant and are also 80% lighter than steel ones; however, their price is 20% higher than those structures made of steel.
