A plug-in hybrid could still be charged with solar panels. But I digress.
When I had the Leaf I found lots of places to charge for free. The only public charging station in town is 6kW and free. At work I can plug in my car for 9 months for the block heater. When I had the Leaf I also plugged it in on the same outlet.
However, it's been several months that I've been biking to work instead, except when the weather is really bad.
Another benefit to a plug-in hybrid here in Colorado are the steep long mountainous passes. In the traditional hybrids the battery fills right away. With a bigger battery, as in a plug-in hybrid, more of the downhill energy could be stored for after getting to the bottom of the pass leading to greater efficiency.
I almost got a new Prius Prime instead of the used Avalon. But I don't think I would have gotten much of the federal tax credit back making the car substantially more expensive.
