Even more to the point- solar panels live quite easily on roofs, deserts, highway medians. Quite a bit tougher to put functioning agriculture in these places!

  Green roofs are a thing, though. https://en.wikipedia.org/wiki/Green_roof https://en.wikipedia.org/wiki/Green_roof

    A green roof is pretty. It has plenty of upside. It isnt a productive farm which is the appropriate comparison here

      >It isnt a productive farm which is the appropriate comparison here Why would 'vertical farming' be more productive then?
      • Misdicorl 6y ago
        Because productive farms require lots of expensive maintenance/equipment. A vertical farm lets you optimize for that use case since its the only use of the infrastructure and you can align everything towards maximum use of those scarce resources. Random roofs don't optimize for that usage pattern, and so you need to use them in an application where the primary cost is the install cost rather than an upkeep cost. Solar panels are a perfect fit. Farms are a terrible fit.
