This is clearly not a winning idea if you're a spreadsheet-loving engineer that can run the numbers, and is interested enough in clean tech to do so. But that's 5% of the population, tops.

To the 95% of people without the inclination or knowledge to check the figures, this looks great! It's a car with zero fuel costs, it's EV charging for people who don't have off-street parking, it's a fix for EVs sitting in workplace car parks at times of peak solar output, and it's most of the benefits of covering car parks in solar panels.
