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.
Radical of a module dual analogues for soc("M"). Radical of a module In mathematics, in the theory of modules, the radical of a module is a component in the theory of structure and classification. It is a generalization of the Jacobson radical for rings. In many ways, it is the dual notion to that of the socle soc("M") of "M". Let "R" be a ring and "M" a left "R"-module. A submodule "N" of "M" is called maximal or cosimple if the quotient "M"/"N" is a simple module. The radical of the module "M" is the intersection of all maximal submodules of "M", Equivalently,
