     Well, here's a dumb question:
     I understand that using a photovoltaic array on your car's roof
wouldn't provide enough power to charge a traction pack in reasonable
time, but could it provide enough of a "trickle" charge while parked
to prevent this sulfation and extend the battery's life? If not, can
someone explain why not?
