Hi Stuart thank you for taking the time to reply, I don’t know about the panels you mentioned, I was really interested to know which of the 3 I have listed was the best choice as the total price is going to be about the same. The price includes an imerser (not sure how you spell that). I am happy with the installers, have chosen them as they did a local fit a few years ago and came recommended. They do a lot of schools and industrial fits locally, it is the choice of kit that I am not sure about. Thanks
