Are PV panels dead load?

What is the structural load of solar panels?

The structural load of solar panels refers to the weight and forces a solar system exerts on a building or structure. This can include the weight of the panels, mounting system, and other related equipment, as well as additional loads from wind, snow, or seismic activity.
