That’s true of everything you build. The cost of land has to be taken into account, but land is much cheaper in some areas than others.
replyYou are assuming that land is expensive and forgetting that building and maintaining panels over long a canal is harder than building over a large plot.
replyHarder but obviously not physically impossible either. From the image I can't imagine what the showstopper would possibly be. Technician on a little dinghy instead of a stepladder doesn't seem like a big deal. Presumably they make it where you can pull the panel off easily if you need to.
