Notice that the anticipated scale of PV installations shrinks enormously in 2008.

The problem with very small PV installations is that they are primarily rooftop affairs.  They aren't going to fuel the creation of commercial scale energy, instead they're a subsidy to the construction industry.

The worst case scenario from the capacity factors given in the original legislation was 15.67% capacity factor.

So that's 1372.5 KwH for every KW of installed capacity.

At a guaranteed rate of 0.32 €/KwH, that's a €439.20 subsidy for every KW installed a year,  €439,200 per MW.  At that rate, you're looking at total payback in a matter of a very few years.

The rate's too high.
