Ignoring clouds, the daily average insolation for the Earth is approximately 6 kWh/m2. [1] So you get about 0.25 KWe averaged daily per m2. Solar has serious land use issues. It is estimated that 1% of the UK would need to be given over to solar to deliver the current power needs. [2]

Noor II CSP delivers 0.66 TWh and is 6.8km2 (200 MW - peak?)

Ringhals Nuclear Power Plant delivers 23 TWh annually (3955 MWe)

A solar plant using the tech of Noor II and the power delivered of Ringhals would be 237km2 - twice the size of Paris.
