This is an interesting concept for sure. But unlike rooftop solar, I think some time would really help this work. Double the power would be great here.
I assume the 1.25kw rating is the total power rating of the cells used. Not accounting for whatever coverglass they have on the cells. And then of course the cells are not mounted at ideal angles which cuts output a fair bit. And it’s not really possible to have them track the sun without huge complexity and aero issues. I would assume the roof would shade some of the cells sometimes. Presumably the cell temperatures would be elevated over standard roof mounts with airflow under them, leading to further reduced efficiency. And the angle you park the car will have a moderate impact in generation over the day.
No doubt it could work. But probably not today...
