With a properly designed house your roof overhangs should already take care of that: https://images.squarespace-cdn.com/content/v1/5e5e91c81d669b...

I feel like we design houses like we design cars and many other modern things, form over function and fix the problems by adding a ton of overcomplicated technologies.
If you have huge openings and no overhangs I'd go for something like that: https://www.youtube.com/watch?v=iPNMp6pMJjk
What about houses with more than one level? The overhangs help not at all on the ground-floor.
SOUTH (or NORTH) is doing a lot of the heavy lifting there!
