Abstract/Summary:

---

When sizing the components of renewable energy systems to be able to cover the load with a certain security of supply the selection of the data meant to represent the meteorological conditions governing the systems performance plays a decisive role. Current approaches comprise either to select or construct years assumed to present typical statistical properties or years assumed to present the most challenging conditions in view to assure a high degree of load coverage by the renewables up to a 100%. When aiming at systems approaching the complete load coverage by renewables it is obvious that long-term data sets must be considered to identify those condition. Here, a long-term data set is applied to examine the lay-out of a PV system assisting the electricity system of the Faroe Islands. For this example, the identification ot the most chalanging conditions in a 56-years set and the conseqences of the use of incomplete sets in view of the occurence of deficit situations is discussed.
