And this technology is ideal for going over rail, road, parking areas and all that sort of stuff so of course it's likely to end up used in those places.

It's also almost certainly going to be painted onto truck roofs, RVs, trailers, boat decks, fencing, marquees, and just about everything else. We'll certainly see rolls of it carried in pretty much all groups that go camping or work in off grid locations - take the roll, steak out two corners then unroll it onto a sunny bit of ground and suddenly you've got twenty square meters of PV charging your vehicles, phones, laptops, and tools. Life boats with power to run desalination equipment and satellite communications will save many lives.

At a low enough price point it's worth it just to maintain charge in an ICE's starter battery when left idle and to power monitoring systems, for electric trucks it's a no brainer - free fuel and extended range for the cost of a paint job? It doesn't matter how little range it adds or how slow the fuel trickes in it'll become ubiquitous pretty much over night.
