Sweden is testing a semi-truck trailer covered in 100 square meters of solar panels::A Swedish manufacturer wants to harness green energy from a cargo trailer’s free real estate.
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.
20kwc capacity: nice also add 20kwh lithium storage at 200kg weight and it could help in few instances like cooling perishable cargo or driver’s cabin when engine shut off, but definitely not to expand range
