I use 10% almost all the time the view is just fine and you are choosing the dark color which also makes the view better.

Instead of solar shades, we use Phifer super solar screens on the exterior of windows. The view of outdoors is above average and it allows us to decorate without using solar shades.

It's always best to keep the heat outside instead of trying to manage it inside. Once it's inside, your air conditioner has to deal with it.

Thank you, Brushworks.
