Why? Thermal solar panels don't need direct sunlight to work, you get more
energy collected on bright sunny days but you stiill get some on dull
overcast ones. Any decent system will circulate a antifreeze mixture so
you don't have to drain it down in the winter...

Ours doesn't. We don't need to drain it.
