Are you talking about disconnecting power entirely, or just generating as much as possible yourself?
Because the first, depending on local laws, is going to be something you can't necessarily do and keep your occupancy permit and be allowed to stay living in the house.
The other is going to be a matter of figuring out your maximum power requirements and sizing a solar and battery system big enough to fill your needs.
Just as a thing to consider: you're talking tens and tens of thousands of hardware if your power bill is $300 a month, and the ROI on this is going to be 10 or 20 years, so if you're not living there that long, it's maybe not worth doing.
Do the math on how much power you use at peak draw, how much power you use in a month, and how big of a system you'd need to generate enough power, and how many batteries you'd need to store your non-solar needs (days with lower production, no production, overnight, etc.).
Extremely helpful, thank you so much! It seems what I might be looking for is more along the lines of using the panels as a compliment to lower my bill overall, at least, from what I understand.
Also, you should consider new windows and insulation/re-insulation of your house first.
I spent ~$6k on new windows and full encapsulation with spray foam (small house, so ymmv) and had my power bill/gas bill drop by nearly 60%.
MUCH better ROI than the solar is ever going to be and it's also included in the energy efficiency tax credits as long as you ensure the R values are sufficient, and you do it professionally.
