Indeed PV is much more expensive now. The lowest I have seen is 25 Eurocents/kWh over 20 years, and that was a MW-scale project - private units are more like the double of that.

For scale, here are the German feed-in tariffs for 2004:

capacity	< 30 kW	30 kW << 100 kW	100 kW <
field		45.7 c/kWh
rooftop	57.4 c/kWh	54.6 c/kWh	54 c/kWh
other building-integrated	62.4 c/kWh	59.6 c/kWh	59 c/kWh

Except for the 5 c/kWh bonus for building-integrated non-rooftop (e.g.: windows, walls) units, for new units these tariffs are reduced every year by 5%, thus for example this year:

capacity	< 30 kW	30 kW << 100 kW	100 kW <
field		43.42 c/kWh
rooftop	54.53 c/kWh	51.87 c/kWh	51.3 c/kWh
other building-integrated	59.53 c/kWh	56.87 c/kWh	56.3 c/kWh
