Keeping battery topped up during winter

I used a small solar panel last winter and the result was...a flat battery.  I have read from MMM that these type of solar panels are only just short of useless.  The type I used are sold by Halfords and others to sit on the dashboard, supposedly putting out 6 amps, in reality putting out a half amp.

I have no electricity where the van is stored and a solar panel would be ideal to keep it ticking over, but which one.....any help would be appreciated.

by recording the discharge and comparing it to the input charge level the OP wont have to 'imagine' anything....he'll have the answer.

Do try and keep up BB! I was not responding to the OP but to Smowe! laughing

They fitted the second panel to the MH today taking it to 120watt. Doesn't do anything for the engine battery though. I may fit another solely to keep the engine battery topped up for the alarm and was thinking a 20watt would have been sufficient for this.

I found this with mine, the drive battery was not getting enough. I found a good auto electrician and he swapped it so that the drive battery gets the power first and when that is full it automatically switches over to the leisure.
