While the sun appears to be directly overhead, that’s where it was 8 minutes ago. Aim 2 degrees to the West (where the sun is at the moment you fire the laser). Once you fire, the movement of the Earth will not alter the path of the laser light.
So I don’t think this is right. The sun isn’t actually moving (relative to us), so when its light hits us, the light is coming from exactly where the sun has been and will continue to be. Just aim right at it!
