Your Modern Louvered Pergola can be built with Fixed louvers that do not move or you can have Mobile, fully functional louvers that open and close to any degree you like.
Mobile Louvered:
The Mobile, fully functional louvers are made to stay put in any substantial wind - so if you set them closed, they will stay closed. They are operated with a matching finely finished wood stick that you use to reach up and push the individual louver sections to the desired degree of opened or closed:

Fixed Louvered:
The Fixed Louvers are set at vertical and do not move. They are much easier to build and are less expensive eventhough the have the same design lines and also provide a great amount of shade and visibility:
