Panel installatiy

[Johandup]

Gents, I’ve bought 14 panels and need to install them. 
On inspecting my old farmhouse with a corrugated roof I found that the brandering spacing too be totally unsuitable for the rail spacing. 
I have 4 lines, one at the top and one at the bottom with 2 in between lines at 1,5m apart. The brandering is 50mm  depth x 70mm wide. 
My intention is to do a portrait installation. 
Do we have to put the solar cable inside conduit pipes inside the ceiling?
Anybody ever had to fix a situation like this?

Any comments and suggestions will be welcome.

I can help with the solar cable answer, there is absolutely no need to put PV cable inside a conduit. Especially in the ceiling when they are well protected against weather elements
