Those cages will get hot in The Sun and so will the water in the drippers. I don’t recommend chameleons be kept outdoors unless enclosures are placed in shade or under shade cloth and there is suitable automated misting.
I’m NOT picking on you. Having them outdoors is great for them, but they don’t have enough options in small cages to escape The Sun and temperatures. You also need to bungee cord those down, in case of strong winds, just to be safe.
