Review of satellite-based surface solar irradiation databases for the engineering, the financing and the operating of photovoltaic systems

This paper explores the possibilities provided by satellite-based surface solar irradiation databases, for the attention of the photovoltaic actors, from the engineering and the financing to the operating of photovoltaic systems. First, the problematic of using meteorological ground stations for the determining of solar dataset or time-series is addressed with the example of the French national meteorological network and the focus made on the South-West part of France: the heterogeneity in terms of spatial and temporal representativeness along with the relevance of the delivered measurement are questioned. Then, an innovative synthesis of 16 satellite-based ISS databases available so far is presented through the distribution of their corresponding features within three categories: spatial and temporal representativeness, data type in terms of component and format, and finally operating mode for the retrieving of the data in terms of price and accessibility. The results of this review shall help photovoltaic actors making the correlation between the available satellite-based databases and their specific needs. (C) 2014 The Authors.
