Maybe today, but basically everywhere south of Canada solar is so high ROI that it's just a question of time before sunlight hours have electricity so much cheaper that the primary daytime parking locations become the favored (slow-)charging spots.

For you to prefer charging there your employer only has to charge you less during the day than your utility charges during the night, so the day/night rate arbitrage can easily pay for the metering hardware and installation (at the next opportunity to install without having to dig the parking lot up just for the chargers), with the rest being profit to incentivize the managers to install/offer this.
