Ah makes sense. Won’t be long until you re smashing itThe 12 on the garage, are 10 degrees, the 28 on the house are at 30 degrees, the 3 on the rear wall IIRC are 84 degrees.
When the sun is low, I do suffer quite a bit of shading from neighbours and a tree, once the sun gets a bit higher in the sky it will really pick up.
