Solar options for standing seam roof

[flanagaj]

After some deliberation, I think I am going to ask the architect to submit a variation of condition for solar PV in the south facing roof.  We have a 17m * 4m roof which is going to be standing seam.  I did consider Catnic Solar, but I think the cost will be way too much and I was wondering whether there are any other options to have solar integrated into the roof.  I am not a fan of the panels being fitted on top of the roof as I think it looks clunky.  Has anyone installed solar PV with standing seam and if so, what did you go with.  Pictures would be great.

Not installed yet, but we're planning to use GSE trays to make the panels more or less flush with the standing seam 

 

The solar company have said there is no extra cost of the GSE trays vs clamps and rails to put the panels on top of the standing seam.

 

We haven't finalised the tinsmith yet. We've spoken to one who has said they've worked with the GSE trays before so we know it's all doable. In theory a saving as there will be no standing seam under the panels. The tinsmith will have all of the flashing details to do around the GSE trays though. (I find somehow things are never cheaper!)
