That's what I thought at first, but upon second look, I do not see any A/C-type vents in the interior of the van, and the exterior does not have the hallmarks of an A/C system.
It looks to me that this is actually the solar system referenced in the description. From the passenger side, it looks like a rack with three stacked solar panels. From the driver's side, it looks like a single panel. Definitely something interesting going on there.
