Warning kinda long post
Here's more personal anecdotal experience - we just finished renovating a house and the remaining gas bits are the stove top (preference for some cooking) and gas fireplaces - ornamental mostly though they can provide a quick local temp bump.
The gas hot water heater is gone, the gas hot air furnace is gone, the gas clothes dryer is gone. Basically I'm not a fan of natural gas (or whatever it's current propagandized name is today) and was trying to get rid of it all together. Can't dissuade the chef in the house that gas cooking isn't the best so compromise was required.
We have fairly large solar install and 2 batteries (luckily all purchased/gone live winter 2018 for max tax break).
Hot water heater : Rheem hybrid

Heat/AC:

One Tesla Model 3 that charges from a nema 14/50 outlet in the garage off-peak (if it ever drives anywhere these days)
To be fair, the climate here has fairly narrow temp range, mid 40s to low 90s at the extreme and good breezes and it's mostly just 2 people and some dogs but also a home office which is a real power hog (many spinning drive enclosures, too many computers).
Electric service was upgraded to allow for 2 nema 14/50 outlets in the garage as the plan is the other car will someday be full electric.
This was a long term plan, the warranty on the inverters is 25 years, solar panels something like that as well. We have 1 year of living with this setup and it's all Covid stay-at-home so less car charging but 99% occupancy with computers running, etc
So far our first PG&E true-up is -$362 meaning even with an all electric house we still produce more than we use. As mentioned, it's a bigger system but it was important that we come as close to breaking even as possible with power use as I am a greenie. But equally important is the area is known for PG&E brown outs as well as just frequent downtime and the batteries are set up to drive important lights, the internet equipment
, the office and the refrigerator so we can in theory last a bit that way, not dependent on flashlights etc
The folks that installed the solar installed the inverter such that load shift is automatic (if PG&E is down, batteries come on < 2 seconds). The issue for your electrical box is not just breaker availability as there are options there

Prior, we would exceed system limit if we ran everything and charged the car at the same time but that never happened and we did upgrade the service surprisingly not as pricey as we feared.
So that's a lot to read sorry, but if the budget can handle it I'm all for as much solar (and batteries) that you can feel comfortable with as it's both a good environmental move but I also honestly believe the stability of the grid isn't necessarily going to get better anytime soon around here, and perhaps worse?
