1. A system for estimating photovoltaic energy through irradiance to irradiation equating with the aid of a digital computer, comprising:
at least one computer processor configured to:
provide with a set of irradiance observations that have been recorded for a location at which a photovoltaic plant can be operated with each irradiance observation in the set being separated by regular intervals of time;
provide with a set of clear sky irradiance with each clear sky irradiance in the set corresponding to one of the irradiance observations;
estimate a set of normalized irradiation with each normalized irradiation estimates in the set corresponding to one of the irradiance observations, wherein each of the normalized irradiation estimates is equal to one of the irradiation observations;
form a time series of clearness indexes with each clearness index in the time series corresponding to one of the irradiance observations, each clearness index comprising a ratio of the irradiance observation's corresponding normalized irradiation estimate and the irradiance observation's corresponding clear sky irradiance; and
forecast photovoltaic energy production for the photovoltaic plant in the computer as a function of the time series of the clearness indexes and photovoltaic plant's power rating.
