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.

Localization of a module primes or maximal ideals are trivial. By the very definitions, the localization of the module is tightly linked to the one of the ring via the tensor product This way of thinking about localising is often referred to as extension of scalars. The corresponding "S""R"-module structure is given by formula_6. As a tensor product, the localization satisfies the usual universal property. From the definition, one can see that localization of modules is an exact functor, or in other words (reading this in the tensor product) that "S""R" is a flat module over "R". This fact is foundational for the use
