Yes, get a battery switch to stop any draws during storage, use it whenever you are disconnected from power.
A fully charged battery will not freeze. most should be charged about once a month to be safe.
You have a good plan with the solar charger, Battery Tender has well controlled solar chargers, but they are a bit pricey. Just Google "Battery Tender Solar", and choose the one that fits your needs.

No problem with freezing in northern Alberta, either.
But solar panels don't work well in winter here due tomorrow snow and the sun low in the sky. I just check the voltage once a month and put a charger on when it's a bit low.
