USD/kWh is not a retail price, it's the price of energy. It can be retail or wholesale. Using USD/MW is like quoting the price of water with respect to the diameter of the pipe - it makes little sense.
Because I don't have data for financing, maintenance and lifetime of the power plants which is needed to provide the retail price per kWh.
Well, my point is precisely that the items you don't have are very relevant and do drive the actual price of electricity for the various technologies. In one case they are included (and even oversized), and in the other they are ignored, or at least unknown. In the long run, we're all dead. John Maynard Keynes

That's why there's more to the diary than just the first two paragraphs :).
If you look risk and maintenance by small window of the scale of physical parameters in the plant:

page 88-90 it gives 2006 cost per installed effective Watt at 21.7 USD. It notes than if more than 10 MW/year are installed this cost would likely go down to 13 USD.
But the interesting line is their "Non-Fuel Fixed O&M" if you look at the tables you see that CPV are low compared to other solar tech (and projections for the future are even lower).
Amonix technical paper for 2006 has a section on maintenance of their CPV systems for the past years.
