Nice post. While I don’t like the politics being pushed, the pragmatic side of me wonders if solar and an EV would save me money. You outlined it nicely!
For example, I live in Alabama where we get lots of sun (free power). And also most of our power consumption is for running the A/C during the warm months (which is when we get even more sun, even more free power). If you live up north (assuming you're in Pennsylvania and perhaps old enough like me to remember the 1979 Sugar Bowl between Bama and Penn State LOL) where you both get less sun, and also most of your energy consumption is fighting the cold during the winter when you get even less sun, it probably won't work for you.
Another is I have a metal roof. That means my 25-year warranty solar panels don't have to be temporarily removed to replace a 10-year shingle roof. Speaking of my roof, since I have no land to put solar panels (most of my 1.5 acres is wooded) the only place clear from shade is my roof. That means I have to have a portion of my roof facing south. Bonus points if the roof has a steep pitch to angle the panels toward the sun better in the winter when the sun is kind of low in the sky and I'm hurting for as much power as I can get during the few hours the sun is up in the winter.
Another thing is sunshine relative to temperatures. Around here, most of the summer days in which it's really hot (meaning I have to run my variable speed heat pump more to cool the house) tend to also be days that are really sunny. So I almost almost always have extra free solar power when I need extra power. Likewise in the winter. When it's really cold (really cold to us Alabamians LOL) and my heat pump with heat strips has to run more, those tend to also be days that are sunny. It's rare I have a cloudy/overcast day on a cold weather day or blazing hot day. If your weather patterns aren't like that it might not be worth it to you.
Then there's your power consumption habits. A younger couple both working often means most of the appliances aren't running during the day, but when both people get home from work in the early evening many appliances are running at once. (i.e. one person is running the clothes dryer while another person is cooking dinner, meanwhile the A/C is running because you let warm air in the house as both of you open the door to come in.) If your house is busy like that in the evenings it means you have to have larger battery capacity than others do to save up power from the day (when no appliances were running) to power the appliances in the evening to minimize pulling from the grid. Another thing is your inverter capacity. I originally had one inverter (before I got an EV and increased my load) and that was usually enough for my wife and me because she's retired and spreads out the appliance use throughout the day (instead of running multiple appliances at the same time every evening). Thus, my 9kW of continuous inverter power could usually keep up with one or two appliances running plus various incidentals like lights and such. That wouldn't have been enough if I had the same solar system a few years ago when both of us were working. Thus, I probably wouldn't have gotten solar back then even if solar was as good and as cheap then as it is now. It works for us now with our habits we have now.
After studying the telemetry from my inverter for a year, importing it into a homemade T-SQL database and crunching the numbers, I added onto the solar system and got an EV. Now I have double the inverter capacity, triple the battery storage, and double the solar panels, though admittedly since 3/8ths of the solar panels are on my north-facing roof (though on a relatively flat part), that means during the winter those panels receive about 55% of the solar power the ones on the south do. In the summer the north-facing panels will probably produce a hair more than the south-facing ones (because the north-facing ones are pointed almost straight up).
Last but not least are other tricks for saving energy unrelated to solar. For instance, when I replaced my natural gas water heater I got a hybrid water heater. It's an electric 50-gallon tank water heater, but it has a built-in heat pump in the top that I can set to optionally run in efficiency mode. Basically, when my wife and I are done with morning showers it can take from 2 hours (in the summer) to 4 hours (in the winter) to heat the water tank. 2 hours running at 300 watts is 600 watt hours (0.6kWh). That's better than a standard electric water heater taking only 30 minutes to reheat the tank, but running at 4kW (2kWh). I ducted the water heater's air intake from the attic so that it draws in free hot air as a good heat source for the water. For the air discharge I duct that too, only it has a wye lever. In the summer months I direct that free cold air into an air intake vent of my central cooling system (free cold air coming from the water heater to help cool the house). During the winter months I direct that cold air into the attic (so my home heat pump doesn't have to work extra hard warming up the cold air from the water heater).
