Those don’t exist.

No one said it does.

Generally speaking, solar panels aren’t optimized for near-constant traveling. As such, it’s “fairly involved from a technical point of view,” said Falkgrim. Despite only recently starting prototype testing on Sweden’s public roads, he explained the project is “about seeing if the solution makes sense, and so far we believe it does.” Although such a design isn’t expected to become widespread on roadways for a few years, Scania’s initial testing shows the tech is not only feasible, but promising.
