Rough estimate of 72 cell panels at 2m² and 500W per panel puts this at a peak performance of 25kw. More than twice the average home installation.

I feel like it could be great for running cooling systems on trailers and stuff like that, not sure if it would be worth the hassle for adding range.

Even on a purposely designed solar car like the lightyear one it really only works because they used all the weight saving and aero tricks possible, which you can't really do with a truck that's supposed to haul cargo.

Yeah. the one good use I see is reefer trailers. Since some times they have to sit long times, with still the coolers running to keep the cargo within demanded thermal limits to keep the cold chain uninterrupted.

Most cooling is obviously needed when it is hot... so in summer and thus sung light time. So the panels would probably nicely run the coolers instead of having a fuel burning generator keeping the coolers going.

During winter, when there is no light. Well it's probably cold enough ambient the reefer isn't using lot of cooling anyway.
