Photovoltaic mounting system Photovoltaic mounting system Photovoltaic mounting systems (also called solar module racking) are used to fix solar panels 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 BIPV). The solar array of a PV system can be mounted on rooftops, 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
Support of a module the word "support". Most properties of the support generalize from modules to quasicoherent sheaves word by word. For example, the support of a coherent sheaf (or more generally, a finite type sheaf) is a closed subspace of "X". If "M" is a module over a ring "A", then the support of "M" as a module coincides with the support of the associated quasicoherent sheaf formula_18 on the affine scheme Spec("R"). Moreover, if formula_19 is an affine cover of a scheme "X", then the support of a quasicoherent sheaf "F" is equal to the union of supports of the associated modules
