Solar panel Solar panel Photovoltaic solar panels absorb sunlight as a source of energy to generate electricity. A photovoltaic (PV) module is a packaged, connected assembly of typically 6x10 photovoltaic solar cells. Photovoltaic modules constitute the photovoltaic array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions (STC), and typically ranges from 100 to 365 Watts (W). The efficiency of a module determines the area of a module given the same rated output an 8% efficient 230 W module will have twice the
Localization of a module of flatness in algebraic geometry, saying in particular that the inclusion of the open set Spec("S""R") into Spec("R") (see spectrum of a ring) is a flat morphism. In terms of localization of modules, one can define quasi-coherent sheaves and coherent sheaves on locally ringed spaces. In algebraic geometry, the quasi-coherent "O"-modules for schemes "X" are those that are locally modelled on sheaves on Spec("R") of localizations of any "R"-module "M". A coherent "O"-module is such a sheaf, locally modelled on a finitely-presented module over "R". Any textbook on commutative algebra covers this topic, such as: Localization of a module In
