Mine faces West also and I took a few different steps to resolve this. Because we also have a pool, I didn't want to block all the sun as that helps heat the pool. So shrubs up to about 5 feet for privacy, extra fan, and an umbrella in a movable stand to provide shade where I want it. The problem with special screens and large trees is they also block the sun in the winter months when you really want the extra light and heat source. The tilting movable umbrella solves that issue. With that and the fan, even in July and August it is very comfortable on the lanai. I am considering an awning that will run the length of the lanai that is motorized and can be extended as needed. For now the umbrella works fine and is a very low cost solution. I got both the umbrella and stand from overstock.com for less then $100. It is 9 feet high and 8 feet across and tilts at the top when opened all the way. The stand is filled with bricks and sand so is very heavy and stable even in high winds.
