I'm not completely discounting it, but 5h seems like a lot for trucks, even if you have more roof area. Tesla's Semi has a 1 MWh battery, which will be drained within a day by most firms, and I imagine Semi 2.0 will have a 2MWh battery. It's hard to imagine the solar panels would keep up with either of them. Even if the panels can generate 100 kWh a day for the trucks, that's still like 1/10 of the day, so more like an hour. But 100 kWh seems really unlikely, even in the future.
