There are a few suppliers that sell solar scavenger panels for charging
vehicle batteries while parked outside the workplace, there are certainly
car ones that sit on the dashboard and possibly permanent one's that can
be
bonded onto the roof, I believe there are also motorcycle types available.
If you make a home brew panel, don't forget you need a blocking rectifier
to
stop the battery discharging into the solar cell when there's no sunlight
and the forward volt drop of the rectifier has to be taken into account
when
specifying the solar panel voltage.
