All true, but there's still the night. Perhaps paired with transcontinental energy transmission (like Australia is planning for Oceania/SEA, or the Gibraltar idea for Sahara->Europe transmission) we can route the excess energy away from the local grid and to places where it is night time. Whether this is better than local storage is another question.
