Hello all,

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 and whether there is a
danger of damage leaving the panel connected when starting the car?

The panel I am thinking of purchasing off eBay has a protection diode
built-in.


These are very popular with Boat owners ... get them cheap on line.
It is such a low trickle charge, there is no risk
