The cost sounds about right but depends on the size. The pricing I received was ~ $1200/window for 5'x6'. Keep in mind that cost is also driven by qty of motors so for your windows circled in red you probably don't need 4 separate shades. Talk to your Dealer/Installer but you can probably buy 2 large shades to cover all 4 and that way you're only buying 2 motors which is a big difference than 4. I don't know your dimensions but making a guess based on scale. I have one large window in front of our kitchen sink that is 10' wide x 4' tall. I have one shade that covers it, thus one motor (and it's quiet). From discussions with Lutron I believe max size for one shade is 12' x 12'. I've been holding off on getting the shades for our Great Room but it's inevitable. We have pretty good privacy so we've been on the fence but ultimately my wife would prefer the shades. It's a series of 8 glass panels, each 4' wide with the middle 2 panels are doors that slide away from each other. So when I set out for pricing I was thinking many individual shades but as it turns out the proposal is for 3 sections (thus 3 motors), at widths of 12'/8'/12'. So I could open only the center for walking in/out and have the rest down. I have the pre-wiring because I want to ease of mind to open/close them 100x/day without worrying about batteries. Also, if it's not too late consider building pockets in the ceiling for them to disappear when closed. It's a clean look.
