Oy vay! Denseness doesn't help, sir.
OK, you have a 4' wide center window and two 2' wide wrap-arounds (@
45 degrees) which bring the OAL to maybe 7', right? If you install a 7' or 8' long shade, it will shade all 3 windows from the sun--if the sun is at 90 degrees to the west-facing window. (Simply offset it to one side if it doesn't.) And if you get one which is 6' tall, it will shade more of the wall, too, adding to your comfort.Erm, that's nice.
P.S: What did you finally do with the redo of your flag driveway last year? IIRC, you were having loads of trouble finding laborers or contractors willing to do it for you.
