I'm thinking of connecting a 12V 10W solar panel permanently to my
vehicle battery as I am not using it very often.
The battery keeps going flat in the cold weather.
What I wanted to know is if others have done this
Yep; I did it for years, as I'd just bought a new battery for my car
but wasn't using it much (at all).
It kept the battery up to snuff until last winter, when -18degC killed
it.
and whether there is a
danger of damage leaving the panel connected when starting the car?
I couldn't tell you that, I always disconnect first. Offhand, I doubt
it.
