Photovoltaic mounting system at the same angle as the latitude of array's location to maximize the annual energy yield of module. For example, rooftop PV module at the tropics provides highest annual energy yield when inclination of panel surface is close to horizontal direction. A study in the tropics showed that the orientation of low-slope rooftop PV has negligible impact on annual energy yield, but in the case of PV external sunshade applications, east façade and panel slope of 30–40° are the most suitable location and inclination.

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
