The data on the site may well be, howver the course if it stull runs was a good one. They used to run a 5 day PV design and survey course, and also a 2 day roofing installtion course and a 2 day survey course. The 5 day design and survey was very well done, including things like how to design strings, voltage drop etc etc - mind you that was 3 years ago!
Don't Ecoskies in Chesterfield do survey and sales training as well as installation training? Again, like Worcester I did my courses there a while ago but were very good.
