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
Galois module is only with respect to the discrete topology on "V", thus making the situation more algebraic in flavor. Galois module In mathematics, a Galois module is a "G"-module, with "G" being the Galois group of some extension of fields. The term Galois representation is frequently used when the "G"-module is a vector space over a field or a free module over a ring, but can also be used as a synonym for "G"-module. The study of Galois modules for extensions of local or global fields is an important tool in number theory. Let "K" be a valued field (with valuation
