I fear a flaming but here goes anyway:
As more capacity is stored in electric vehicles there is a synergistic benefit to solar beyond just lowering the electric bill. Distributed solar and batteries benefit the grid if contractual agreements to share the vehicle’s power when the grid needs it, and then the owner gets a big return for supplying peak power, the grids most expensive kind. If my commute is 25 miles and my F150 has a range of 300+ miles I could sell back both the extra solar I normally produce, and some of the capacity in the truck. If I plan a long trip I just use my phone to limit that option. When most of us have vehicles with similar or greater capacity we could be powering our homes for a day or so with automatic switching similarly to how pad mounted generators do it now and the vehicle would make the outage go away. I know some may need the vehicles during the storm or outage but if you didn’t, such as at night, weekends, general outages when businesses are closed or for a disaster, then it would benefit you and possibly the grid as a whole. Essentially you get the option of having a grid tie normally and an independent battery off grid system when needed. No extra batteries to buy.
For some reference:
I lived off grid for 10 years with a 3KW Dunlite wind generator and used flooded lead acid batteries which lasted well over 10 years. That type of battery is still viable and inexpensive today. I have had solar installed on my last two RV’s experiencing reliable electric power for them over 15 years. Nothing ever failed on any of these self-installed installations and except for a service on the Dunlite and topping up the FLA batteries no other attention was needed.
