Correlation of fluctuating wind pressures acting on photovoltaic panels installed on a flat roof

Abstract

In the case of installation on an existing building, the wind load of the photovoltaic panels acts on the fixed part of the roof at the same time as the normal wind load, but as a result of examining the simultaneity of the two loads, it was shown that the maximum value of both loads does not occur at the same time, and that it is sufficient to design a combination of the maximum value of the load on the roof surface and about 0.65 times the load on the panels.
