Its 2 145 watt panels in parallel. A Sunforce controller. Some wire, and Big batteries.
I 've had them on my Motorhome for years. Joe took em off and set them up to charge his batteries. About a 10 minute swap to put em back on the Mhome.So amazon had a set of these with a parallel cable for about 230 bones. Sound about right? Ive nit sourced a controller yet tho. Just looking at panels. I think a cool gig would be to mount them on my plane trailer roof. Maybe have like a removable mount deal.
