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.

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:

• Wind: normal temperature, large physical forces/motors, no hasardous material
  
• Solar thermal: high temperatures, moderate to large physical forces (stirling engine or other), may be hasardous materials (to move heat)
  
• Solar PV: normal to moderate temperatures (they cool the PV cell if I understand correctly), no physical forces (just moving small mirrors on ground), no hasardous material.
