You are over simplifying Solar and cost, there are soooo many variables that goes into cost of ownership for a PHEV.As I understand it you don't HAVE to plug in a PHEV. If you don't it will operate just like a regular hybrid. But if you have the ability to plug in you can drive full electric up to the limit of the battery. Typically 25 to 45 miles depending on model. So if your daily commute is 25 miles you can be all electric with recharging at home. And still have the ability to use gas on longer trips.
If you get 40mpg and gas is $3 your cost is .075 per mile, with electric it is on average .0388 per mile or about half. And that average includes a lot of older EV's that are not as efficient. Gas @ $5 takes your cost per mile to .125 or 3 times the cost of electric. And if you have solar your electric cost is minimal or zero.
PHEV are not for everyone but in some use cases really save you money. Of course they are also almost always heavier and more expensive so that has to be calculated in as well.
I have excess solar right now so a PHEV would have nearly zero fuel cost for my daily use.
But if you have a 24-mile commute (like me) and your PHEV has a 35 miles range, then in theory you should be all elec, but weather plays a huge part of the range, I know many PHEV powers and for the most part, they use it has a Hybrid, and still plug it in at night.
