Thanks Richard , Steve its just a £45 one off I have my standard public liability but not special solar insurance as this is the first time I have done one in 6 years and will most defo not be doing any in the near future so special insurance won't be needed , so Steve is Richard right or are you saying I must do it your way ? Pls advise
Turning off the inverters only does away with the AC. The DC still produces in the panel as RC says it does. However, the DC needs the AC to shock you. By turning off the inverters, the DC cannot shock you. With the inverters left on, it is conceivable that you can be on the receiving end of a potentially fatal shock.
Forget people saying they are sealed units, so are upvc windows and we all know they can go after 3 weeks or 8 years. Panels are the same. I'm sure you will be fine taking a chance on a one off job of this size, but there is no way on earth I would let myself or my lads do a commercial installation with the inverters left on. You won't know anything about a shock until you are lying on your back with your hair smoking!

Regarding insurance, I would still get it added to your policy. If you let your car insurance expire and thought you could get away with doing one journey, you could virtually guarantee the cops would pull you over that day! Please don't take offence, but because this is your first job too, there is a higher chance of something going wrong. Depending on who you are insured with, you can get the cover at no extra cost. For the sake of a phone call it is worth the peace of mind.
Hope this answers your questions.
