Local legislation can make a huge difference. In my country, you can install solar panels without storage, pump the electricity directly to the company, consume theirs, and pay the difference. Our house produces more than we consume, so charging an EV would still be mostly free for us.
If the energy company didn't buy our electricity, we would be forced to use batteries to store the surplus to charge the EV batteries.
The only disadvantage is that during a blackout, we still produce energy but can't use it. Fortunately blackouts are very rare in my region.
