Does my single skewed purlin roof need re-inforcing before installing solar?
I've been told that I might need to reinforce my roof before I can install a solar PV because it has just one Purlin.
What type of reinforcement would be needed and is this normal?
Ask the installers if they have an inhouse Structural Engineer, if not then you will probably need one to assess the existing roof timbers and supports, plus the additional weight going on the roof.

Most times you can get away with not re-inforcing, but check with the installers first. If your installer says 'no' you need proof on paper from the company that the installion will comply with building regs.
