I am too!
Thanks Steve,
Yes I know they are very different and have been speaking with a company which installs solar farms (one of my customers) who has been in the business a long time, im still learning and just want to do the job safely which I'm confident i will.
I wasn't expecting anyone to tell me exact prices, just a rough guide which Darren helped with, there is no way I could get away with charging £1 a panel on this job as there is 814 of them with easy access , was thinking around 45p a panel.
