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. Photovoltaic mounting system Photovoltaic mounting systems (also called solar module racking) are used to fix solar
Serial module turns out that a serial ring "R" is a finite direct sum of homogeneously serial right ideals if and only if "R" is isomorphic to a full "n"x"n" matrix ring over a local serial ring. Such rings are also known as primary decomposable serial rings . Serial module In abstract algebra, a uniserial module "M" is a module over a ring "R", whose submodules are totally ordered by inclusion. This means simply that for any two submodules "N" and "N" of "M", either formula_1 or formula_2. A module is called a serial module if it is a direct sum of
