That's a long video, I got a bit bored and did not watch it all. From factory solar roof only drives fan, does not charge battery.

I did try to make it charge battery as well as drive fan on my PF D2 but the solar panel is not powerful/efficient enough. Newer cars have more powerful panels and if you diverted all of the power to battery it might work better. I wanted to keep cooling fan working as well. It was slowing down discharge of battery if I left car without driving for like a month but did not keep it fully charged so I still needed to connect it to mains charger if not using car for long period of time. This also slowed down fan and reduced cooling so in the end I reverted back to fan only. I was looking at changing sunroof with a one from FL car with 4 rows of solar cells instead of 3 but decided that it will probably not be enough anyway.
