A 1 hectare receiving plant taking in 2kW/square metre won’t be burning any cities, but generate 120MWh continuous base load even with just 25% efficiency.

Dial that up tenfold and I suspect you’ll be fine - especially with the plant in the desert (nothing to burn)

1GWh/y/ha. That’s a 4,000 ha requirement for the US electrical needs, about 10 square miles.
