    I heard that the Toyota Rav4 Prime is going to come with a glass roof with some sort of electronic function that will fog the glass over, like privacy glass that will block out glare and heat, hopefully Tesla will incorporate that technology in future models.

    I use the NEMA15 to charge my M3, so when it's unplugged during the day I turn off the main power to the NEMA. I don't want the Tesla charge box and wan to be powered all the time. Is that a good idea or do you just leave it powered all the time? What are you-all doing?

    I bought a Tesla sunshade. I cut a piece of mylar reflective heatshield in the shape of the sunshade. Then place the sunshade on with the mylar silver sheet in between the glass and sunshade. It helps some but nothing will reduce the heat when the ambient temp is 110 (like yestereday) and in the full sun, it is 135 in the car.

    The "solar thermal load" wouldn't be the pass-through — infrared rays getting through the glass and heating the passenger. It would be the heat loaded into the glass by all the frequencies of light that it's absorbing (especially visible, since it's dark-tinted and absorbing light instead of mirrored and bouncing it away). That load of energy put into the glass has to go somewhere, and physics being what they are, it will radiate out as heat. A completely opaque roof could have a solar thermal load: try touching a metal roof on a sunny day if you don't believe me.

    Hey I was just letting you know since you're using the third party one, I also have a third party roof cover. I sewed a clear suction cup to the back middle of the rear shade and it's totally imperceptible and limits the sagging significantly.

    Your heat test is skewed. In the first one, you start the timer before turning off the A/C, and on the secord one, you turn off the A/C first! It sounds like the heat blocking has to do with the size of the holes in the mesh, as with the Amazon one they are smaller and blocks more heat, while the Tesla ones are larger and lets more heat through!

    When you're doing your sit test, what you're feeling are the infrared rays hitting your face. The denser weave, the more it blocks the rays from coming through but that does not translate to a cooler car. Infrared rays are converted to heat wherever the rays hit whether it's your face, the sunshade mesh itself, the rooftop glass or the interior seats. Your warm-up test resulting in 2m, 36s and 2m, 10s confirms this. The trick is to block the rays from touch the car in the first place. Try this experiment, put the sunshade outside ontop the vehicle and re-test how quickly the Tesla warms up. The true value of any sunshade it to impede the interior from warming up so you're comfortable and the air conditioner works less, especially when it's just parked in the sun and the Tesla starts to cool itself in the middle of the day.

    Just came across this video and I have some comments:

    1. The roof on the Model 3 does indeed block UV rays – specifically UVB (as does all glass) and UVA. (And it should be noted that the side glass does NOT block UVA – so if you are concerned about sunburn/skin cancer, you’ll want to get those tinted as I did with UVA-blocking tint. However, UV wavelengths are NOT the ones that transfer HEAT. That is infrared, a completely different wavelength.

    2. The heat is produced when the infrared waves strike a surface. The glass is hot because it is absorbing some of the infrared rays. Your head gets hot because some of the rays pass through the glass and hit your head. So measuring the heat inside the cabin is pointless as a test since the heat will get in anyway – even if you used totally opaque coverings over all of the windows. Your garage does not get hot because of the tiny windows on the door; it gets hot because of heat transfer from the roof and sides being struck by the sun (conduction through the walls).

    3. The sunscreens reduce the amount of infrared that strikes your head. That is going to be directly in proportion to the degree of opaqueness they provide – so a tighter mesh will reduce this more than a looser mesh. So – obviously – if you want to eliminate the heat on your head, you’ll need a totally opaque sunscreen. And – again – that will NOT stop heat from getting into the cabin, it will merely prevent the infrared from being absorbed by your head and making it warm directly. Think of this as being in direct sunlight, then going under some tree branches with partial sun coverage, and then going under an awning. The less sun striking your head, the less heat is generated on it.

    4. A better test here would be to put a target in the car suspended over the seat – a piece of paper, say – and measuring the temperature on the top of the paper and on the seat in the shade below the paper. That will give you a much better idea of how much infrared is striking the surface of the paper and eliminate the effects of the ambient temperature in the car.

  9. Ronald Garrison

    Doesn't the car have software that tracks and logs the interior temperature? That could make it easier to run the tests, and then you could make multiple runs, increasing your confidence in the results.

    Thanks for this, very useful! One thing for the 2.0 test if you ever do it. It is not only for me the overall temp, but mostly the temp of the seats when I go in. So, measuring the temp of the seats with one, the other and none (maybe after 30 mins at noon or something) would be very useful!

    Great video as always! LOVED the measured way you tested both products and configurations! I got a cheap set of sunshades from Amazon that also had an added reflective metallic / silver "sheet" that you could put between the shade and the roof. I'd be curious to quantify how much more of a difference that makes. I'd have to assume a LOT of difference since it would create slightly more insulation zone and reflect WAY more light / heat.

    I feel like a more effective solution would be to have glass-facing side be mirrored/coated such that it reflects more of the incident energy back. I can't imagine that would add a significant amount to the cost. Hell, you could probably DIY it and affix some foil to it yourself.

    Great vid as always…would love a model 3 but must say I do like the electrically retractable screen for the paonoramic roof in my cheap and cheerful MG ZS EV (yes I know the cars are not in the same league but it's never the less a nice feature)

    I'm in Florida, before covid, I showed my car and gave rides weekly. I have the Tesla front shade and removed before each showing. Over the months the clips came off and 3 were lost.
    My grandson 3D printed more clips.

    I agree with the perfect timing of your video. I have had the sunroof Tesla shade and it definitely helps, but I didn't want to pay through the nose for Tesla's rear shade. I ordered just the Sopedar back shade from eBay for $24 delivered. It should be here in a few days. I reason that there can only be so many core manufacturers of these. If it doesn't work out I am not our that much money.

    Great review. I've had the SUMK one for a year now in the mid-Atlantic region in my M3 (and just received one for my Y but haven't installed it yet) and it's worked really well. Would have liked to see you test them while driving with the windows open to see how they compared to the wind buffeting, if any. For me the SUMK doesn't flap around while driving. Wondering how the TESLA one does since it covers the whole back window. For the clips, when I don't have the shade up (from Fall to Spring), I put them in the underneath section of the center console in a bag. Easy day. As a side note, I don't feel the radiant heat through the Model Y roof like I do on the 3. Not sure if it's because the roof is farther away from my head (I'm 5'9" and bald), or the glass has different insulating proeperties. However, I've only. driven the Y about 150 miles so far having just picked it up.

    There is a difference between the heat entry and the glass feeling hot. The roof stops shorter wavelength IR radiation entering the cabin which heats you and the inside of the cabin directly – this is the 99% blocked. When you touch the glass this is heat absorption by the glass (and UV protection) absorbing energy and is a function of the "black-body" energy absorption and then emission of energy by the material. The problem is that the hot glass FEELS hot and emits its own energy so radiates heat into the car. In effect the glass behaves like a metal roof, but does not contain an insulation layer as in a solid metal roof. Adding the sun screen is preventing this IR energy radiated by the hot glass preventing the energy "shinning" on you (that hot glass). These glass UV coating layers allow this longer IR radiation out of the glass from the sun screen – so allowing the sun screen IR radiation to reflect back out, the work by stopping the shorter wavelength light coming into the cabin.
    It would be much better to fit a white sun screen – as this would reflect more IR out of the glass roof.
    Sorry about the physics answer.

    Makes me not want a model Y or 3. It should come with one. All manufacturers design glass roof with pull screens of some kind. This design was found first at original Toyota Scion TC.

    This is one of many reason I find odd about Tesla. Most car manufactures complete extensive cold/hot testing. Wouldn’t the need of a retractable sunshade been apparent? It’s a honest question. I’m not trying to sound like a Tesla hater.

    Another great video, however I’m still torn on what to do myself. The ceramic tints would be the best solution I think, but they are VERY expensive and I cannot get them right away. Honestly I do not like the look of the aftermarket rear sunshades that only go halfway down the window, but I see why they do it – that shade looked way too dark to see out the rear window. I wish you would have shown how the rear window looked from the outside with either shade on. I still think the Tesla one looks much cleaner though.

    I recently got a front shade from Amazon for my Model 3. (I have XPEL 35% tint on the entire rear glass; highly recommended.) The shade from Amazon was branded “Basenor”; it was only $30. Quality seems really good, and the frame and the plastic clips look exactly like the more expensive Tesla shade you showed. I can’t speak to the material density compared to other shades, but the heat rejection is quite noticeable. The only downside is the fit; it is not perfect; the shade stays in place well, thanks to the clips, but the frame bows in a little on the rear so that a small gap is present. Not enough to be a big deal, but aesthetically it looks “off-brand” in an expensive car.

    We have a 2020 Model X and it came with a Tesla front shade. We found the summer sun was too much for us and installed the shade. The shade took care of the heat problem, but cut off too much of the view above us. So we had tinting added which accomplished protection from the sun and allowed a much better view than the shade did. If I had known about the clear AIR 80 tint, I would probably of tried it so as to maintain the best possible view.

  23. OneMusic StoryTesla

    My advise. What I did in my P3D is, I purchased small suction cups with hooks and I hooked it up above the mesh and suctioned it to the glass and that stopped the sagging completely. I purchased 30 suction cups from amazon at $6… also, I used amazon shades back in 2018 from Basenor and Toplight from Amazon. I paid $69 in 2018. But prices have fallen. I found Dasbecan for 39.99

  24. Because Tesla

    Form over function vs. Function over form. The Tesla branded shades are aesthetically more appealing but are more translucent so more sun (heat) gets in. Any shade that is more opaque will block more heat from the roof. The ultimate in shade for the roof is ceramic tint from a tint shop. Thank you for making this video. I found it to be very informative. Could you tell a difference in appearance from OUTSIDE the car – looking at it from the back?
