2015 A-S Burford Duo

Well, here I go again. I've bought yet another Auto-Sleeper, I just can't keep away from them. This time it's a 2015 Burford Duo. I went way way across country yesterday and did a great deal with the dealer, in fact both they and I were happy. We hope to collect it in two weeks time. She who must be obeyed has just asked me if we need to get a solar panel fitted!!!!! Why didn't I look yesterday? So, would someone in the know please let me know if a solar panel is fitted when new. it'll save me harrasing the dealer in the morning should it have one fitted as standard. I know it has rood air-con which is a bonus. 
Regards,
David and Val.
