Abstract: A computer implemented method of estimating at least one solar irradiance component, the method comprising: obtaining a sensor measurement from an instrument to provide a measured global horizontal irradiance (GHImeasured), wherein the measured global horizontal irradiance (GHImeasured) consists of at least an estimated diffuse horizontal irradiance (DHIestimated) and an estimated direct normal irradiance (DNIestimated); providing at least one modeled component, wherein at least one of the modeled components is a modeled global horizontal irradiance based on an atmospheric model (GHImodel); calculating an irradiance estimate modifier (IMOD) in a computing device according to the measured global horizontal irradiance (GHImeasured) and the modeled global horizontal irradiance (GHImodel); and providing at least one estimated solar irradiance component by a computing device according to the irradiance estimate modifier (IMOD) and at least one modeled component.

Abstract: A computer processor implemented method of measuring, monitoring, comparing and diagnosing the power generated of at least two renewable power systems provided to at least two consumers and alerting at least one of consumers in the event of comparative underperformance, the method taking into account at least two diagnostic variables including weather and the renewable power system cover status (such as covered by snow), wherein the at least one data server determines comparative information for a predetermined geographic area based upon at least two diagnostic variables, and at least two normalized performances to provide a comparative value; and informing the consumer of the comparative value in the event of an underperforming comparative value.
