Hmm. I would argue the main use for a large STATIONARY charging station, as opposed to a potentially-portable generator, would be if it charge vehicles, and do so with less hassle than jumper cables.
Compared to putting solars on the vehicle itself, this would be dubious unless the station had some degree of power storage and the ability to output charge faster than the panels can take it in. From a realism perspective, it might be a bit dubious, however…
From a gameplay perspective, I can see this having one big benefit: it could be used as a way to make electric scooters and other small electric vehicles, the ones without panels (and without the space for a sustainable number of panels), more viable as-is.
As it is, non-solar electric vehicles are worthless as-is because there is no efficient way to charge them. Adding a charging station could be useful by being a “flavor” item that compliments an existing flavor item, and combined serve a valid gameplay niche.
