I'm guessing the chart is based on insolation only. When you factor in political stability, the Sahara region will look much less attractive. All that ocean in red will have some other drawbacks, too.

Solar insolation values are highest where the wear and tear on solar panels are the highest. Solar panel delamination and power storage costs are killers in hot areas. Unfortunately, costs per kilowatt hour for solar is very high in these very "suitable" areas.
