Well I found this great video, but I have not yet followed the instructions on it yet, it seems to be very thorough and is explained very well.

My plans for Angel Cottage Acadamy Garden include home-made solar panels running along the 16ft roof of the garden cabin in the back garden and possibly also angled on a frame at the front of the house.

I hope to use this design for the cabin roof and shed roof, but at a later date I want to create a design feature or photo-voltaic sculpture for aesthetic reasons.
 
I firmly believe that permaculture, organics and eco should also be artistic and not just functional. And that it is possible without losing functionality or too much valuable growing space.  I am not personally, very fond of straight lines, due in part to my permaculture training.
