Neeed more pics from different viewpoint to help understand.

Is this the front or the back of the house? Any chance we could get a wider shot of the property and maybe an around pointing do the direct south, so we can figure out what angle we need to cut the sun off at.

If this is the back of the property, have you considered an awning?

Have this product on my eBay watch list. Provides 85% screening. See these made as roller shades all over the place. Believe there's a large selection of colors plus multiple places you can purchase. Another bonus, you wouldn't use the window film, which you'd take off in winter to allow the sun to help warm the porch. HTH, Rosie

Thanks for all the responses! Please find a wider picture attached with 11:45am sun. Awnings can look nice, as replies have demonstrated, but I'm concerned initial and storm costs. I'll be sure to get some estimates before I install the film, though.

What about a fairly tight cluster, or grove (3 or 5) of Pindo Palms? They grow fairly fast but mature at around 20' ht. The fronds get a decent reach ... and no leaves in the pool at all! In a group they will produce shade. Shield the patio side with a root barrier if roots concern you.

It is the front-and-center palm in the picture.)

Well this might be a far-fetched idea, but if you don't actually need that space to be enclosed, you might consider removing the windows to make it an outdoor room with or w/o screens, put in several ceiling fans, make it more a part of the outdoor living, which I am guessing you are in Miami and so you are outdoors year-round. Being from New Orleans, I can relate quite a bit. The windows are what is making the sunroom into a greenhouse, I am guessing.

How about a Japanese Fern Tree (Filicium decipiens) for shade and then palms, banana leaf with expanded mulch for additional shade and landscaping. Fern trees are evergreen and shouldn't cause much, if any debris. They grow about 25-30ft with an expansive and dense canopy.

Closing the loop on this topic: By tinting the windows of the rooms I wanted to protect with the awning, they are now livable all year long! The tint doesn't make every day look dreary as I had feared, and am happy with my course of action. Cooling costs have reduced noticeably, but only enough to pay for tinting over 5 years.

Specifically the tint was "solar gard true vue 15" for large windows and 30 (lighter tint) for skinnier windows in more common rooms.

Also, I'm putting Pindo Palms front and center in my driveway loop (not pictured).

Thanks to all for the advice and proof of concepts!
