"Low E" window tint or film offers a lot of reduction to heat in sunrooms. The higher the reflectivity, the better the heat reduction.

We had a kitchen on the south side of the house with a lot of windows and no room for a practical awning for shade. It was so bright in that kitchen it looked like a Spielburg movie and it got hot in there every summer day. No amount of redirecting A/C airflow would solve it. Rather than reflective tint I added exterior screens that blocked 80% of the light and heat. I put them up in June and it greatly reduced summer heat and the overabundance of light in that room. You could still see fine through it as we did have a nice view of the city, but it reduced heat in the kitchen by 10*F. In October I would take down the screens, wash the windows and we benefitted by the light and heat gain during winter months.

Just another option.
