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.

Do you have any numbers :-) ?

I have a sunroom, what sort of numbers are you asking for? It's a partly cloudy day, about 22C in the room, without heat. And about 7C outside.
