There is a way to do it. But these solar companies doing it now don’t set them up in that manner. No batteries, just a direct feed into the grid.
I know because a friend of mine sells them. The way they’re configured and installed you can’t use the electricity generated in your own home. That’s one of the reasons I passed on it.
That and the ROI didn’t work.

And that set-up without battery bank backup is useless when needed the most, grid goes down for whatever reason so does the house....why bother.
Like I said in a couple of other posts, it’s a lifestyle not necessarily a ROI decision...
If you live in a rural remote location, you will have to provide most of your own public utilities, like water and sewage, but based on experience dealing with the aftermath of a hurricane, living remotely means you are the last to get power back....

If I were to build a new house, in Florida, so results will vary...but I would build the following...
A modest size home no more than 2000 to 2200 Sq. Ft...
The house would be built using Insulated Concrete Forms (ICF), energy efficient windows an doors, a Tin SIP paneled roof and finally to the extent possible Gas Appliances...the goal would be to make the house as energy efficient as possible to lessen to demand for electricity...for example, ICF construction is supposedly 70% more efficient than a traditionally framed house...
the other design I would use is mini-split AC units instead of central heat and air..
