Abstract

The paper takes an engineering point of view on the use of some basic climatic parameters as input data into energy models for the determination of the thermal performance of solar systems. The assumption behind the approach is that the climate of a given geographic location can be characterized by just three fundamental elements, that is the monthly daily average of the horizontal global radiation, the air temperature and the wind velocity. The advantage is that in addition to the location of the principal European observatories many local networks of simple meteorological stations where these three elements are measured and averaged can be included. The approach is to develop a synthetic month which is divided into three categories of typical days; sunny days, days with mostly diffuse radiation and fully cloudy days. Other aspects of the method are the utilization of LiU and Jordan correlations and the normalization of the measured solar radiations to the values of the extraterrestrial radiation. The method is illustrated mainly with weather data measured at Ispra but also with examples from other European stations. Applications of these synthetic months in solar energy system models are given with comparison of results obtained with real climatic data.
