• We were not doing it the wrong way, but we were having a different financial calculus: the goal used to be to maximize the revenue per m² of solar panels, but they have become so cheap that now we try to optimize the revenue per m² of land.

    It used to be profitable to motorize panels to follow the sun. Now it is more profitable to have two panels suboptimnally placed but maximizing output per m² of land.

  • Another idea that this sparked in me was that it might be a lot easier to combine these vertical panels with green roofs. I’m a big fan of these to slow storm water, cool buildings, and add biodiversity to our otherwise fairly barren cities. Normally there is a bit of a conflict between solar panels and green roofs but I wonder if this could allow you to have both?
