Photovoltaic mounting systems (also called solar module racking) are used to fix on surfaces like roofs, building facades, or the ground. These mounting systems generally enable retrofitting of solar panels on roofs or as part of the structure of the building (called ). As the relative costs of solar photovoltaic (PV) modules has dropped, the costs of the racks have become.

The solar array of a can be mounted on , generally with a few inches gap and parallel to the surface of the roof. If the rooftop is horizontal, the array is mounted with each panel aligned at an angle. If the panels are planned to be mounted before the construction of the roof, the roof can be designed accordingly by installing support brackets for the panels before the materials f.
