What size and recommendations for Solar please?

[EuroTrotters]

Despite answering a similar question a few moments.

I have a Caravan with a Motor Mover and 80ah battery.

Just looking for recommendations for a small panel for top ups when on THS etc.

Please?

Should the solar watts = the ah of the battery?

I know nothing about solar. My 2nd battery is powered by the alternator only.

Is the 80ah only used for the motor mover ?
If yes then a 100 watt solar suitcase with controller would do you.
Open the suitcase, attach the crocodile clips to the battery select your battery chemistry eg lead acid, and point the panels at the sun.
Depending on controller type you'll get 5-7 amps an hour, in bright sunshine, put into your battery
