This 15-minute video from the YouTube channel Electric Future takes a close look at the questions of where we are at in terms of integrating solar cells into cars and whether it is worth it to integrate solar technology into several thousand pound vehicles.
Putting solar cells onto a car and/or using portable solar units to charge an EV are apparently a flash hot button issue for many electric vehicle advocates, some (many?) of whom patronizingly, in my view, immediately dismiss such efforts as “useless”.
I have long been very interested in the question of how much it (does not) matter(s) when one plugs one's electric vehicle in, especially if, like I do, I have the choice of plugging into a home rooftop solar system.
Many years ago, I wrote extensively on this web site/blog about the many intricacies and complexities of what I call "solar offset" charging of an electric vehicle vs. directly filling up with electricity that has been/is being produced directly by a (home rooftop) solar system connected to the same electrical box into which an EV charger and/or the wall-socket into which you're plugging your EV into.
