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 ideals) then the localization is denoted "M" instead of ("R"\"p")"M". The support of the module "M" is the set of prime ideals "p" such that "M" ≠ 0. Viewing "M" as a function from the spectrum of "R" to "R"-modules, mapping this corresponds to the support of a function. Localization of a module at primes also reflects the "local properties" of the module. In particular, there are many cases where the more general situation can be reduced to a statement about localized modules. The reduction is because an "R"-module "M" is trivial if and only if all its localizations at
