Unfortunately the power you get from a car sized solar panel is not enough to run a modern design of car. The solar cars raced in Australia are highly specialised, ultra light weight and usually driven by young people who are not very heavy. It makes much more sense to use a fixed array as a power source and use the car as an energy delivery system between home and place of work. With the cost of all the poles and wires, this paradigm is looking quite attractive!
Thank you so much for the input and yes, I agree completely. Although I am very interested to see if we can exceed our limitations in that area. I found these very interesting cars by HONDA (https://www.youtube.com/watch?v=Z5nc2N9IBkI), also (https://www.express.co.uk/life-style/cars/870093/electric-car-solar-power-Sono-Motors-Sion). I agree on it being fixed array because we can set the tilt angle, choose a location corresponding to solar profile, but I wonder if with the rise of solar cell efficiency, the improvement in vehicle's energy efficiency, car batteries and the ability to predict solar radiation in certain locations can allow this shift in paradigm to happen and to be sustainable for the user.
However, the priority in my openion should remain on enhancement of efficiency and energy efficiency of solar cell and vehicles, respecitvley.
