Solar trickle charger for 2012 my RX350

[Dino Gloucester]

I leave my car for months between two homes and inevitably have to jump start or replace the Battery. I want to try a solar tickle charger but don’t know how feasible it is as it’s typically cold weather.  Is there a way to easily manage connections and source of power, i.e. are any of the “cigarette” lighters in the interior that are constantly powered?  Easy way to run wiring from the Battery to the interior to the solar cells?  Is there a recommendation as to which system to use?  Thanks in advance !
