Do you have references for how much a solar plant costs to build and maintain? A breakdown of costs would be good.

> Operations & Maintenance must include fuel costs…

I presume this was done to make section 5.4 "Fuel cost sensitivity" easy.

> Rooftop solar however only supplies the grid with power after the houses needs are met which is a significantly narrower area.

What about if people are over-specifying their solar PV system to make use of net-energy-metering (or high feed in tariffs) to reduce their annual bill (for instance in California)?

Don’t just think about what happens when these systems are at 100% output. At 5% output that home is sucking power from the grid while the solar far is providing the grid with power. Which means even if every home and business adds panels a solar farm will still supply some electricity directly.
