    Also looks great.

    Buuuut it’s expensive and needs constant maintenance. It’s also a greater risk, there have been cases of trees being blown off of buildings like this, although if properly anchored with shitloads of netting this shouldn’t be an issue.

    I do wonder if it’s more practical to just put solar panels there though

      They work great together. Bifacial PV panels let enough light through for growing, and make excellent vertical edge barriers.
