Concentrating photovoltaic and thermoelectric solar facilities base their operation on collecting the

Concentrating photovoltaic and thermoelectric solar facilities base their operation on collecting the
direct component of solar radiation. Given that the direct beam that reaches the Earth's surface varies
greatly in time and space, it is common to assist the bankability of projects with a solar resource
assessment. Sun-tracking collector plants are typically examined via a time series analysis of measured
weather data and test reference years. Such analysis, which considers the eventual presence of clouds,
may be complemented with the use of the synthetic clear-sky year assuring the maximum theoretical
availability of direct normal irradiance at a site. This work introduces for the first time the concept of siteadapted clearest-sky year (CSY) and provides a methodology for its generation. Three methods to build
the CSY and one algorithm to detect clear-sky moments are proposed. [--]
