Photovoltaic power station Photovoltaic power station A photovoltaic power station, also known as a solar park, is a large-scale photovoltaic system (PV system) designed for the supply of merchant power into the electricity grid. They are differentiated from most building-mounted and other decentralised solar power applications because they supply power at the utility level, rather than to a local user or users. They are sometimes also referred to as solar farms or solar ranches, especially when sited in agricultural areas. The generic expression utility-scale solar is sometimes used to describe this type of project. The solar power source is via photovoltaic modules that
Injective module number of results are known, . Let "S" and "R" be rings, and "P" be a left-"R", right-"S" bimodule that is flat as a left-"R" module. For any injective right "S"-module "M", the set of module homomorphisms Hom( "P", "M" ) is an injective right "R"-module. For instance, if "R" is a subring of "S" such that "S" is a flat "R"-module, then every injective "S"-module is an injective "R"-module. In particular, if "R" is an integral domain and "S" its field of fractions, then every vector space over "S" is an injective "R"-module. Similarly, every injective "R"["x"]-module is an
