One problem with solar in Europe, especially in Northen and Eastern Europe, where heating in the winter dominate consumption, is that almost all solar potential is in the summer, when less electricity is needed. This is basically a result of the Northern latitude of Europe (Madrid and NY has about the same latitude). For wind it is the opposite. Wind is strongest in the winter when the consumption is highest. This makes wind a much more attractive option in Europe than solar, given that electricity can't be stored easily at grid level.
