Photovoltaic system the outer edge. Electrically connected and mounted on a supporting structure, solar modules build a string of modules, often called solar panel. A solar array consists of one or many such panels. A photovoltaic array, or solar array, is a linked collection of solar modules. The power that one module can produce is seldom enough to meet requirements of a home or a business, so the modules are linked together to form an array. Most PV arrays use an inverter to convert the DC power produced by the modules into alternating current that can power lights, motors, and other loads.
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
