Those A4 sized solar panels are great for keeping a car battery's charge
topped-up if you make only infrequent short trips in the car. And with
just a few cheap external components you can modify the charging current
to prevent the battery getting cooked on very bright days. Add just a few
more components on top and you can fit it and forget it - the car will
always be 'on the button' no matter how long you leave it standing.

even if it's in the shade for most of the day?
