Résumé

Solar radiation at ground level is a necessary input for sizing and performance modelling of photovoltaic (PV) systems. This chapter deals with problems faced by users when accessing solar radiation data and outlines present and future solutions. Users generally need values of global daily or hourly irradiation with a spatial resolution from 1 km to 20 km. Relative errors of daily irradiation should be less than 20%. Spatial coverage (continent) and temporal coverage are of importance. The data must be available conveniently at low cost. In several regions, solar atlases have been made by interpolation of ground measurements, taking into account the local variation of climate. Satellite data offer an option to provide solar radiation maps from regular sampling of spatially-distributed data at a wide geographical coverage. Time-series are also obtained by weather forecast models. Digital atlases have been created as integrated information systems. They comprise a database and software for its exploitation. The co-operative systems are connected to other servers that provide necessary weather data to compute solar radiation quantities. This survey of databases and information systems shows that in a general case, there is a discrepancy between user needs and available information. This conclusion supports the efforts made in integrated information systems and co-operative systems to overcome the technical limits of measurements by using the information and communication technologies.
