Even wind power still turns a generator, but solar is just completely different than everything else

They’re actually quite similar to thermoelectric generators. But the potential difference between two semi conductors is created by a heat differential rather than by photon excitation.

Thermoelectric generators have been used on various rovers and deep space probes as well as in remote lighthouses.
