Batteries?
Starting this year, in Romania you cannot put new PV capacity online without the storage for it, is mandatory. Possibly for existing ones, but I am not sure.

You either have to significantly oversize the PV (easier said than done, when its energy density is already not that high per m2), or have enough batteries to last for multiple days of full load. If you do the maths that’s a lot of batteries
The main idea is to then import power from somewhere sunny and/or windy or mountainous, using money you saved when they had the rain and you had the sun.
Batteries and other storage mechanisms will gradually reduce the need for doing so, but aiming to entirely eliminate all need for cooperation with others seems a bit paranoid.
So you can have storage, but not too much, only as much to still be dependant on the grid.
See the hypocrisy here?
Not in Poland, because you are too independent.
"According to the adopted act, devices with a capacity of up to 30 kWh are exempt from any construction procedures; only reporting to the grid operator (OSD) is mandatory. Those between 30 kWh and 300 kWh in a building and 30 kWh and 2000 kWh freestanding are obliged to prepare a land development plan and make fire safety arrangements."
