Battery conditioners
Discussion
I park my car offsite in a rented garage, no power. Options are therefore limited regarding battery top up.
Will a decent quality solar panel on the garage roof feeding into the socket in the boot keep the battery topped up enough to get past the two-week-dead-battery line? Thinking winter, there isn't going to be two weeks where I don't drive it for the other 3 seasons!
Anyone found this solution to be viable or makes no to little difference?

I would have thought 2 weeks not driven would be fine but obviously not guaranteed.
I personally use 3 weeks for those cars not able to be easily on a ctek but this doesn’t include Aston.
It does include my dark horse which has a lot of electrical gubbins including updates being fed through and a tracker.
A solar panel on the roof “ must “ allow some power through so as a backup might be worthwhile though in case that 2 weeks not driven gets extended.

Options have been discussed in this section already, I think!
However, as to a "decent quality solar panel" rather than quality, it's about size, so it's not what you do with it but how big it is. A 40W panel would be handy but a 20W one mated to a charge controller should be just enough.
I have a Halfords one https://www.halfords.com/motoring/battery-maintena...
and one of these: https://www.ebay.co.uk/itm/351217380749
You can see the connectors are the same. SAE I think.
This is for use on my 911 and it just about keeps it going. If I left the car without anything, it would require jumpstarting after 3-4 days.

The battery on my V12V lasts about 5-6 weeks and still plenty in it left to start the car.
I would have thought solar into an optimate would be more than fine to keep it topped up. Optimate and CTEK both offer solar panel kits, but its expensive, im sure you can buy the separate components cheaper. If you already have a compatible CTEK or Optimate charger then maybe it could be easy just to buy their kit....
