What do they do? 2012 Fisker Karma Solar Panels

What do the rooftop solar panels on a 2012 Fisker Karma do anyways? Charge the 12v battery? Extend the range? Something else?

That’s absolutely stupid. Add 5-10k to the price of your car so that your fan can run?

I wonder if they had other plans for it 12v or HV pack but couldn’t work it out in time for production.
