We live in a very sunny climate and have a very bright and sunny house. We had UV coating put on all of our main floor windows to protect the furniture and carpeting. We purchased UV film from Lowe's and installed it on the two garden level windows in my sewing room which is a walk-out area of the basement. It was not difficult to do. We had it installed on the main level because of high windows and the need for tall ladders. In the past, in another house, we experienced sun fading. We had a sun room in a house we bought that had sun faded carpet. We re-dyed the carpet and had the windows professionally coated. We lived in the house 15 years and never had the carpet fade again. However, I made a quilt for the bedroom and it faded (and rotted) where the sun hit it.
