Compared to the 700km claimed range (which seems very optimistic), that implies you would need to let the car sit for two weeks to charge on solar alone - more if the weather is not totally perfect or there is any shade.
So if you're wanting to do a multi-day road trip, it's of stuff all use. You're going to be relying on the big battery and the grid; the solar is a rounding error.
If you're planning to do <50km/day commuting/shopping etc... please don't get an off-road SUV tank, and probably not anything with 700km of range. Get something that weighs half as much and put 5x as much solar on your roof. It'll still be cheaper overall and the panels will last longer.
If you're actually in the small segment that needs off-road capability and an SUV (say, a farm run-around), congratulations. Definitely don't get a car with solar on the roof because it will immediately be covered in dust, and the minor dents and whoops-a-small-tree-fell-on-it will break the panels in the first year. You also probably want to park it in the shade wherever possible.
Again, stick 5x the panels on the garage roof and get something cheaper.
