      That’s why I added an order of magnitude to the total land area requirement

      From a few seconds of googling (so the figure may be wrong), in the UK the average solar panel output per m² is 186kWh per year, about half of the NT figure.

      So if everywhere was the UK, we’d need 0.6 percent of total land area.

      Because we don’t have a grid that stretches from the northern to southern hemisphere, you’d need ~5 times the amount in winter (already included in the annual average figure used, but we’re looking for a very conservative estimate), so 3 percent of total land area if everywhere was the UK.
