The walls are stone, as you can see, and are very uneven. Alot of faffing will possibly be needed to get them to lie exactly on a 90° plane, and not at 95 instead, so it is a very good point that even laying at 85° would be better.
I plan to use unistrut, so could definately use a smaller rail above and bigger below.
I would then have to take the possiblity of a little slither of panel to panel shading in play, so will look into it.
If that is the case, slightly smaller panels would give a better gap between the top and bottom panels
The planning officer here, when i enquired 2 years ago about the possibility, said 200mm extrusion from the house, so definatly possible to maximise tilt
Yes, the 2 horizontal can be flipped to vertical and take up the same spacing.
Not quite sure why i decided on horizontal, but i thought, with the bar split in the middle, it would look more "window ish" that way, compared to the other.
Horses for courses i think.
If i did go with the smaller panels, they would definately be put vertically, so.... the real answer is, just a quirk of my brain i guess
