> Saudi Arabia has plenty of sun This could be a problem as above 25c panels can lose efficiency so temps in the middle east could drop panel efficiency quite

  Given a constant level of illumination, solar cells perform better at lower temperatures. But for higher total generation it's better to install panels in hot-and-sunny regions than cool-and-cloudy ones, even if the panels in the latter region convert a higher percentage of light to electricity. Cold-and-sunny conditions are harder to come by, but on (e.g.) a clear winter day at noon, with cold air temperature and plenty of sun, panels can perform beyond their nameplate ratings.

    So where is the most efficient place for solar panels, given that the solar panels are heated by the sun, they could be coated to reflected IR. A cooler climate could help heat be convected away. High altitude deserts like the Atacama might be ideal, but there's less atmosphere for convective heat transfer. I do love an optimisation challenge.
