I hope they dont have storms/hurricanes in the area,that thing can be knocked down and there goes the solar panel
That timber frame is massive and isn't going to get knocked down. I suppose in a high intensity hurricane, the solar panels will be ripped off the frame, but if you've got that going on, your house is probably in trouble too - you've got other, larger issues, so you can just as well criticize homes for not being hurricane proof. Few homes will survive 120-150mph winds. On the other hand, few homes will ever experience such winds.
If someone wanted to prepare for a heinous forecasted storm, they could probably just dismount the panels from the frame, the same way someone might screw in plywood panels over windows on their house to prepare to weather the storm. You could probably put your solar panels in the garage, and as long as your garage is still standing after the storm, remount them.

Still has quite a bit of refining to do, but the basics of a working vehicle are there.
It's an interesting vehicle - reminds me of some of the designs submitted in solar races, mostly by university engineering research groups. These guys are trying to achieve similar performance, while making a vehicle that will be street legal and practical as an everyday driver, pretty cool.

Yea, it's interesting in that they're going in a very different direction from other new automakers. Another odd bit about this is that they're also using in-wheel motors which normally would have an issue with unsprung weight, but supposedly these motors are very light for the amount of power produced.
I think for the highway side, mostly stand-alone EV charging stations, this is probably going to end up being part of the standard build. A lot of stations have awnings of sorts for sun and shade as well as a small one-story convenience store, and so I think what will end up making sense with batteries and solar panels going down in price is that the standard build for stand-alone refueling stations is the roofs of both having solar panels and there being a stationary storage battery on location.
They'd still have utility hookup for power, but they'd be able to produce a significant amount of the power needed from solar panels that is used immediately or stored on site with any excess sold back to the grid at peak periods (if there are any) and possibly charging from the grid during the periods when there is the most excess supply over demand so that the financial model for them would be a combination of selling power directly to people charging alongside arbitrage on the electricity market where it's selling at peak time of use costs and buying from the grid when it's lowest (possibly even being paid for storage if large excess supply from the grid), and meanwhile it also provides some redundancy during periods of the grid going down.

Yeah, I saw Jay asking about that... I mean, the extra unsprung weight probably does have some meaningful negative effect, but you've got the two principles describing the car just prior to its introduction after years of struggling, they are basically marketing it... now, they have been joined by some experienced industry collaborators in the past year and have revised the design considerably with their input, is my understanding... and if this was just a fatally dumb engineering tradeoff, I imagine it would have been addressed with that input.
P.S. If I recall, Rivian has motors at each wheel, presumably unsprung mass as well? Or are the wheels driven by short shafts from chassis-mounted motors?

Yep, Rivian has four motors, but they aren't in-wheel motors, but are instead a set of two motors each paired (a pair for front wheels, a pair for rear wheels) and next to each other, slung low, basically inline with the wheels and towards the middle of the vehicle that drive each wheel via a gear reduction, a fairly long axle, and a CV joint.
