Thanks for your prompt comments, much appreciated. I take your point about mixing portrait and landscape panel mounting, but looks are not that important to me (they are to my wife though!) - what bothers me is that if I'm shelling out such a massive sum to have an array installed I want to be damn sure that I am maximising the benefit of doing so! Due south is to the side of my house, so there isn't really the opportunity to see them at a distance to appreciate the true ugliness of a mixed orientation of panels...
On the gap to the edge side of things, my roof is slate - which I understand is not a favourite of PV installers! But that does mean that nothing's cemented in, other than the ridge tiles. I am happy to accept the wind loading argument, but I'd like to know whether it's 2 or 300mm...
Some installers say 200mm and some say 300mm, I suppose it depends on who they studies with. I was personally told that 200mm from top to allow for wind loading and 200 mm from bottom because if it rains you want the water to drip into your gutter, not over the side of your roof.
We may all have different views.
