By the end of 2008, cumulative PV installations in Spain are expected to exceed 800 megawatts, twice its original 2010 goal.
I also found a vague referece in another of my sources [pdf!] about quadrupling capacity in Spain in 2007:
In Spain, existing uncertainty on future legislative developments fostered unsustainable growth of 300% in 2007.
It is difficult to keep track of the multitudes of small projects. Some try to do it via official permissions, some via distributors, some via sellers, some via producers. A year ago, industry and politics agreed in Germany to put in place some registering system to be up to date (after just the ministry estimation for 2005 has been corrected upwards by something like 100% cumulatively over a course of two years), I don't know what became of that. *Lunatic*, n.
