This atlas contains tables and maps displaying monthly means of global, diffuse and beam solar radiation as well as sunhours for a large number of represenative sites in Europe. Tables show radiation on both horizontal and inclined surfaces. The political developments in the European Union and within neighbouring countries are considered. The text section provides an introduction to the systematics of solar radiation measurement and calculation. The solar data presented in this book is a useful source of information for the estimation of the energy harvest potential for solar systems. The data base is provided on two 3 1/2" disks for more ease in computer assisted design work.
