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.
Module (mathematics) to zero by "f". The isomorphism theorems familiar from groups and vector spaces are also valid for "R"-modules. The left "R"-modules, together with their module homomorphisms, form a category, written as "R"-Mod (see category of modules for more.) This is an abelian category. Finitely generated. An "R"-module "M" is finitely generated if there exist finitely many elements "x", ..., "x" in "M" such that every element of "M" is a linear combination of those elements with coefficients from the ring "R". Cyclic. A module is called a cyclic module if it is generated by one element. Free. A free "R"-module
