It IS a stunt, in the sense that the solar feature is technically independent of the charging stations. The message is clear, but there is no necessary link between the solar elements and the place you go with your electric car to charge up. Placing them there is probably a worse decision that placing them optimally. That's makes it stunt.
And there is also a strong argument that the manufacturing and installation costs of solar farms has a long payback. They are a battery in that sense - energy invested in them slowly comes back out. PRobably petro-energy. So intially solar is a net negative in eco-impact. Same with wind.
