Unless you park it for a few weeks between uses, solar cells don't come
close to providing enough power to make it a viable charging option.

Ooops. My bad. I meant the roof of my house.

So you charge it at night from the solar panels?

Or perhaps you charge batteries in the house on good weather days, and
then transfer to your car at night?

Sunlight
(with losses) Solar panel on house
(with losses) Battery in house
(with losses) Battery in car
(with losses) motor.

This is pretty green?

How many good weather days will it take to drive to work once?

I could live quite happily without freeways. In fact, given my 6 mile
(round trip) commute each day, I'm considering an all-electric car as
my next vehicle.

All-electric cars have the problem of limited range. I'm thinking of
a plug-in Prius for my next car. It's an electric car for short trips,
and a hybrid for long ones. With solar panels on the roof to charge it,
it becomes pretty green.


Have you researched the process of making solar panels? Things aren't
as "green" as they seem...

"Green" is a religion, in which party-hack politicians are the gods.

Personally, I prefer a religion in which the only God is more perfect than
any human could even be or even imagine.

What voltage do those cars use? I assume it's more than 12V. If so,
you'll have to series connect several solar panels to match what you
need. And then, if it's an oddball voltage, you'll have to build your
own charge controller to keep from overcharging. And then, does the
battery type used require a constant voltage or constant current to
charge them. If constant current, you will have to build your own
current source. None of this is un-doable, just some dinking around.
If the voltage required is quite high, you will have a fair investment
in solar panels...

The current crop of electric hybrids use about 4,000 AA
Li-ion batteries in series-parallel to get 800-1000 VDC for
the motors.

The specs I've seen on the Honda Accord hybrid
show 120 NiMH cells giving 144 volts at 6.0 Ah

The Prius also uses NiMH cells, a total of 168
and a peak voltage of 201 volts and 6.5 Ah.

Of course in the US that voids your warranty. In Europe they have a
button on the dash to use it as an all electric when around town and
then go to hybrid for longer trips. Instead of just shy of 50 MPG
they are running in the neighborhood of 100 MPG.

The reason for not having the button in the US is the battery
warranty.
