Plug in solar with grid tied..

My state NY just legalized plug in solar panels. I have a 15 amp circuit that runs outside the back of my house with nothing on it except a single outlet. Seems perfect to use for this. I also have a 14.7 kw array, with a 10kw inverter professionally installed system I've had since 2015. What happens exactly if I was to add a plug in system in addition to a home with grid tied one?
