Could you elaborate on that solar cell setup? Where can I buy one? I'm
having a slow leak problem that no mechanic can seem to diagnose. After
about a year, the battery won't crank after sitting up overnight. I
installed a battery cutoff switch to disconnect the battery overnight so
that my car can always start the next day. But I like your solar
solution better if it can keep my battery charged. Thanks.

The sun doesn't shine at night. I'm not trying to be a smart ass. The
solar trickle chargers usually put out 5 to 10 watts. Assuming you have
reliable sunlight they are useful if your car sits for days. Many new
cars have onboard electronics that pull a few mills all the time and the
solar charger offsets those.

If your battery is draining down overnight you have a problem a solar
charger won't fix.
