portable solar array and large battery to charge up volt?

I rent a house and can not add solar panels or a home battery to the house. I do have a large and very sunny yard to utilize. Anyone looked in to hooking up a solar array to a storage battery and then using the battery to charge up the electric car (Volt and Bolt in my case) during the night? I drive about 6 miles a day and my wife will soon get a Bolt and be driving 12 miles per day. If we have to use the home's outlets sometimes, no big deal.

There are things like this:

Not recommended, they aren't really UL or code approved, but do allow you to offset utility power with small panels.
I actually have one, but for experiments only.
No battery required.

To make an off-grid solar to vehicle power supply is quite complex, due to the minimum input power requirements of the OBCM.
I know they make a big deal about connecting to the grid. I was wondering though, if I already have solar I should be able to add a few panels with something like this and it might go unnoticed?

How have you been using it?
