I was surprised last night when I left work to see that the station at my building had completely disappeared! Well, not completely. It turns out they'd moved it about half a block to where there's a gap between buildings. I'm guessing they did that so the solar panels would get more direct sunlight. That could have been why the kiosk was acting flaky when I first tried my American Express. It kept resetting itself. Maybe there wasn't enough juice.
I'm not an expert in photovoltaics so I might run it by some guys at work but the panels they're using seem undersized. If they're having trouble in June, it doesn't bode well for November.
