Global solar potential is badly skewed: deserts are a lousy place to put solar panels. Their only advantage is that overcast is rare. The best sites are tropical and sub-tropical calm fresh water with limited overcast, to float panels on. It is probably worth making a reservoir to float them on, even in a desert. Nobody knows how long floating panels will last, because there hasn't been time. Warranties assume they are very hot all day.
