Balcony solar panels can save 30% on a typical household’s electricity bill and, with vertical surface area in cities larger than roof space, the appeal is clear

    In the Northern hemisphere, in Winter the Sun is at a low angle, so vertically oriented panels might produce more. As an example, I have a sunroom and at Winter’s Solstice the sunlight reaches about 3-4 meters into the room. At Summer’s Solstice there is no direct sunlight in the room, as the Sun is overhead.

      couple of things to note:

      1. Not every balcony is southern facing
      2. Most older European homes don’t have A/C yet, so electrical costs are more during the winter months (that trend will change though I imagine)
      3. I think the numbers @Valmond@lemmy.world was asking about involved power output, that of course depends on the size of your array, daily/monthly/yearly differences in weather, and all sorts of little nuances that’s hard to say without averaging out years worth of data.
