Solar Roadways is a meme company for a reason. Paving with solar panels is a nightmare on pretty much every axis: installation, maintenance, cost, reliability, efficiency, safety, all of it. And while tessellating every surface with little panels gets more energy than not (and is the only option if that's all the land you own, like people adding panels to their own houses), it's dramatically easier and cheaper to lay out 1MW of panels in one 100m X 100m square, than 1000 hetrogenous 1kW panels mishmashed over dozens or hundreds of buildings. For large buildings, then, yes, it's a pretty clear win. The IKEAs in London have large arrays on their roofs, for example.
