摘要： Location functionality to determine the geospatial location of a PV module is described. This functionality may be performed at the PV module site itself as well as remote from the PV module site. The location functionality may involve the analysis of data collected from the location of the PV module or modules being analyzed as well as data from locations of other PV modules, which are not being analyzed. This data, from other PV modules may be gathered, recorded, and used as a benchmark, or for some other purpose in embodiments.
