Think stupid simple- or is this impossible?
No, stupid simple is not possible.
I'm not aware of any commercial product that does what you envision.
Even if you were able to use DC straight from the panels to the car, you'd still need a sophisticated CHAdeMO charger that knows exactly how much solar power is available. And that charger would need a DC-DC inverter to boost/buck the solar panel voltage to the appropriate voltage for charging the car.
If you want stupid simple - grid-tied is about as simple as it gets.
A standalone system has to be much more complex and I just don't see it working well without at least a couple batteries.
