- I test out a third party glass roof shade and the Tesla brand. Is the premium price of the Tesla brand worth it?

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.
This is the correct explanation. There are a few Tesla Sunshades with lighter coloured material and/or an additional reflective layer between the glass and the mesh-like sunshade. I plan on getting one of those.
I agreed. Would you share which one you would get for
your roof shade? As I am planning to get a M3. Cheers
Thanks, was going to write the same answer. It's even arguable that the use of these sun shades may cause hotter cabin temps, especially at white interior cars.
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.
Great comment, I was thinking along the same lines, with this test.👍👍
UV light still carries energy (a lot more per photon, in fact, than infrared) and when the UV is absorbed by a surface (your head, the car seat, whatever) it will definitely heat up that surface. Hot objects tend to radiate heat in the infrared, so that's what you perceive as heat, but it's far from the only wavelength of light that carries energy and can heat you or your car interior. That said, of the solar energy reaching the surface of the Earth, about half is infrared, 42% is visible light, and 8% is UV. www.fondriest.com/environmental-measurements/parameters/weather/photosynthetically-active-radiation/
Does this mean one should tint AND get a roof shade?
@@FeelLikeGastly Depends on what you want to accomplish. I should note that I have seen later model Tesla vehicles with safety glass for the side windows, which will block UVA, so tint would not be necessary from that perspective but could be valuable for aesthetics or to cut brightness.
Going from first principles: Heat transfers by conduction, convection and radiation. The screens you tested block some of the sunlight, but this gets absorbed by the black material, which heats it up a bit. It turns out black surfaces and glass both have a high emissivity (the fraction of how much heat is radiated out from a surface). So a lot of the blocked heat eventually radiates out from the sunscreen, as well as convection of the air in the car, spreads the heat out everywhere. Sunshades for windshields are not black. They are silver or white, this reflects light back out of the car, and has the added benefit of a much lower emissivity than a black sunscreen. This is called a "radiant barrier". A shiny surface emits less infrared and so transfers less heat. Think aluminum foil. You want a silver or white sunscreen to have a much bigger impact on keeping your car cool Some sunscreen makers even sell you a separate silver screen that can go between the sunroof and black sunscreen. Or just use some aluminum foil. Of course, the more light you block, the less light you get in the car, and the less you can see out the beautiful roof. It is a personal trade off. More important to keeping the car cool in the sun is a good silver or white front windshield sunscreen. The front window has almost no tinting.
Why did Tesla create a glass roof without built-in shades?
Mike I really appreciate the effort you go to in producing your videos in a clear and concise way. I have found placing a sheet of clear bubble wrap packaging between the shade and the glass roof made a very significant improvement in reducing heat in our model 3 last summer in Australia!
The orange reddish tint is no longer present on the model 3 and Y. There was a change in roof glass in late 2019 and it no longer shows that warm color when wet.
Thank god, that was really ugly.
Does that affect anything? Are the newer cars better or worse at blocking the heat and UV?
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.
Perfect timing on this video. I was just complaining about the heat from that roof yesterday. I love the roof although I wish I had an insulated shade for the summer months. I would also give anything to have ventilated seats like I had in my previous vehicle :-) Great job on the review.
Vynl wrap the panaramic roof black or some other opake colour or heavy tinting it could be another option.
If Tesla gave an option for all metal roof, I'd go for it over the glass
Freudian: I think a WHITE shade (mylar might be best) would absorb less sunlight than a dark version would.
Bill Kiele Yes. White would likely work better from a physics perspective.
The vynl wrap that has little holes in it will let you see out and it can be any color you want or even a picture that you may want to display.
June 2019, my first trip out of Humboldt, car was unaltered in any way; I got my left side of my face sunburned from Mt. Shasta to Grant's Pass on the way home. I made an appointment for a tinting on Monday morning. Next trip was Reno-Lone Pine. I never really felt the need for a sunshade on, throughout. But if we ever get to go out again, well, you've got me thinking. Thanks for taking the time, Mike!
Always wondered about the sun roof's solar blocking ability. Thanks and easy way to reduce the heat in those hot summer days. Especially for us Aussies
Thank you for the testing and reporting on both sunscreens. Nice and concise presentation!
Appreciate this beautiful, detailed comparison video you made. It certainly took out the confusion in my mind, and I’m gonna not gonna get a roof cover, till I feel I absolutely need it.
I live in Texas and had the entire sides, back and roof covered in Llumar IRX tint and the windshield in AIR 80.. It has dramatically reduced the solar load in my cabin.
100%... im in florida and I have the same tint, at 5%. it DRAMATICALLY reduces the heat! before I got tint, I had to put the AC down to 67 to feel nice. but now I keep it at 72-74 and I get the same amount of 'nice'.. so its also helping same energy from the battery by allowing the AC not to run so much
Same here! you can't own a car in Texas without having window tint on it, without being comfortable!
Mark's Tech your car must be a light color 😅. I keep my AC at LO during summer time but mine is black and if I keep it under the sun it reaches 120F inside in a few minutes but I agree that the tint (good quality tint) helped tremendously.
Same
Thanks. San Antonio gets pretty hot, so great advice…
I purchased a third party shade for my Model 3 roof. Sun temperatures were cut down significantly inside the car when the outside temperature reached 103 degrees. It was a good investment. The cost was almost half of the Tesla brand. The material is like a black mesh net. It is held in place by plastic clips. You can not see through it, but your rearview camera and outside mirrors are adequate.
Very helpful video. Appreciate your efforts of doing the test and videos to help us all.
I just watched your vid on the sunshade and agree completely with what you analyzed. When I first received my model 3, I immediately noticed the heat from the roof. I live in South Florida so it easily reaches over 100 degrees in just a few minutes on the interior of the car if the ac is off. I bought an after market sunshade ( I don't have the brand name handy) and it came with an underliner that is like a windshield sunshade with a silver reflective surface on one side. Significant difference although the roof is no longer transparent. I seldom drive looking through the roof so this is not an issue. I have even toyed with the idea of a thin layer of foam rubber in between the reflective surface and the mesh so as to imitate the headliner that was on my previous vehicle. Easily taken off during the winter months. The clips on the aftermarket are as you described but a little contact cement or super glue takes care of the problem. Extra clips would be desirable also.
Another great video. Thanks. I got my car 2 summers ago and right away noticed the heat on top of my head (where my hair has somewhat diminished). I bought the Tesla front panel and got the rear panel a year later. As others have noted, these don't do much when car is parked in sun for a long time. Need an opaque windshield screen, and the window Vent feature on the phone app is very helpful.
Love the videos man! This will come in handy for the hot days to come
Hi Wham Bham Teslacam i'm a fan. 😊
Nice work man. I dig your reviews, always very practical advice. "Just a guy testing things out", perfect :)
Great review, really appreciate you taking the time to conduct these tests. I ordered my sunshade direct from Tesla, but good to know 3rd party options are just as good!
nice comparison, I bought the sun shade from Tesmanian for 69 dollars for my model Y. It does its job well but the clips are the same as the amazon ones. Very easy to install and the thing I like about it the most is you don't feel the heat on the top of your head. I live in So Cal and it get triple digits all the time here in the summer. Great job
Very thorough review, great work!
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.
Nice review and I appreciate it because I am in the market for a rear shade for my MS. What was not really covered was the driving experience - I purchased mine for driving in the Midwest and Southwest US. I live in Texa but over 90% of the time my car is parked, it is in a garage and it rarely gets above 85 degrees, so I have/had a completely different perspective on this product and what I was looking to accomplish with it. I wanted to eliminate head heat and reduce AC use while driving. Seems like both products accomplish this but the benefit of being able to see through the Tesla shade so well is huge for touring in a car. And since you can see through the Tesla shade, no un-aesthetic black line across the back window to see out. I already own the Tesla front shade and after watching the video I am sure that I will purchase the Tesla brand rear shade and would still recommend it over the third party for the Model S. I am not as frugal as the Frugal Tesla Guy, but I think there is more benefit for the Tesla shade to consider here than styling alone. Thanks again Mike!!
Found the internal temp sensor can be off as it is directly under the windscreen on the bottom of the display. It can actually show higher temperature than is actually there. The heat build up/temperature indicated is much less if you point the screen away from the sun. Obviously at midday that isn't possible.
Great review, practical advice!
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.
Very thorough. Good job. 🙏
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
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.
Mike, Good review on an item that is difficult to evaluate. I live in a hot climate, Miami, and like yourself, I wanted to try out a roof sunshade on my 2 year old Model 3. The Tesla brand shades are overly expensive. Like yourself, I went to Amazon and saw several choices including the SUMK set you bought. But there was another set for sale, the ASAKA, that looked identical, and the price was very low, only $23.99 for BOTH pieces! I bought it. It did not come with a storage case; otherwise, it looks and installs the same as yours except for a small difference in the design of the plastic clips. Like yours, the front and rear shades fit perfectly. I’m very happy with this product. I do think having roof shades makes a difference. I found I can raise the cabin A/C temperature setting 2F° and still be just as comfortable. The roof shades blocks some heat and saves some battery energy. Having said all that, I checked Amazon for availability. They are presently out of stock of the models each of us purchased! However, there are still other very similar ones sold by Amazon at prices much less than what Tesla charges.
Love your informative videos. Would you have an update on a 3rd party product that would fit the Tesla Model 3 2021? I understand that the sunroof is a slightly different size on the M3 2021's.
Even the lowly MG ZS EV with its full length panoramic sunroof that opens has an electric blind to cover it. Why couldnt a car that costs more than twice as much have something so fundamental?
You can always tint it, but be careful on early M3's as the double paned glass had a defect and a tendency to break from excess heat
Great job on the very thorough review. I purchased the Amazon one.
One of my first missions was to find a cover for front roof glass. Heat and intermittent shadow/light from above while driving drove me a little nuts. I wanted to find less of a screen and more of a total block out shade. I found two rectangular sun shades, correct width with wire trim (and butterfly design print on one side) and by overlapping and adhering them together they fit in this area. The side facing up is the silver material. Now I have butterflies above me all the time. It’s girlie but effective. And It is easily removed, etc. Thanks for demo....I like the Tesla back screen visually and fit quality ....don’t like price....
I have a model S and I purchased 3rd party ones off of ebay, and they work and look similar to your 3rd party ones! But I tried using the clips mine came with and yes they too just would fall off, so I found I dont need the clips! They just slide in in-between the glass and the interior roof piece without any issues. So I just leave the clips in a baggie.
And I've found living in FL these are a godsend!! My interior stays cooler and darker.
I purchased the Tesla sun shades shortly after taking delivery in Sept. 2018. At the time I don't recall any third party options available for me to consider. What I do like about the Tesla shades is that the rear set, by going all the way to the back of the car, diffuses headlight glare at night (in addition to what the rear view mirror does for this problem). Both front and rear shades provided a bit of road noise dampening. I've also noted a slight wintertime benefit in that the shades provide a bit of protection from the cold glass overhead on chilly days.
I was thinking of getting actual Tesla brand sunshades for my model y. Would you buy them again? Is the install quick and easy?
@@theticoboy I now have a 2022 Model Y. Weather was over 100°F locally yesterday, but I did not feel I needed or wanted shades for my Y. In fact, after driving awhile, I had to turn the a/c temp setting up one degree as it was almost getting chilly inside the car. Model Y has a great HVAC system.
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.
Thank you for studying the effectiveness of sunshades. We live in Colorado and use the Tesla screen on our Model S hatchback. Our big black lab travels with us in the hatch and we found that he still gets too hot. I bought an inexpensive heat reflective sunshade for big trucks at Costco for ten dollars and slipped those thin reflective shades between the Tesla mesh and the glass. It works great! I often charge with a napping baby in the back seat and plan to use the same system to augment the overhead mesh system with a near 100% reflective system. They are very lightweight and fit nicely behind the Tesla mesh screens. Pet owners especially need to appreciate how hot the back of a Model S becomes even with the mesh sunscreen.
Is there a source for the slip in reflective sun shade from Amazon as I do not belong to Costco as a member.
Is there any chance that the glass could get so hot sitting in the sun that the reflective shade or mesh shade could melt or worse catch fire ? Any smell from sitting in a parking lot in the sun for a few hours??
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.
The real question should be why doesn't that come with the car?
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.
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)
Great video. Where did you find the background music? I really like it.
I think the glass roof is stupid. It's way too hot greenhouse inside and by the time you tint it and shade it, not worth it
Thanks for the great video!
I'm looking for a roof shade and I'm wondering: does this roof shade make any noise when driving with the window open?
How’s the rear visibility with both in the rear? I’m considering the Tesla rear to reduce light while driving from other vehicle’s headlights.
Great topic, there are many aftermarket solutions but I'm not sure I fully understand the problem.
What is the solar heat gain from each of the windows in a Tesla (roof, windshield, back windows and front windows all have different shade characteristics)?
How does the existingshades effect visible light?
How does the shading effect infra-red heat? (which windows have the most effect?)
How does glass shading effect UV (potential skin damage)
Lastly, do aftermarket tinting options have any negative effects on the glass?
This might be too much of an undertaking for one person however there seems to be few undisputed facts available vs the amount of money spent. Would be a great resource
I'd get the Amazon one for the front, and the Tesla one for the rear so I could see through it. Probably would want to look at window tint films as well. There are some good ones out there.
Why not use a IR thermometer to get a fast/live idea of the heat?
Can you buy the Tesla clips and fit them to the amazon version?
Ceramic window tint on rear, sides, and windshield makes a massive difference. Since I still have hair on top of my head I don’t notice any heat from the “sunroof”. I used to feel it on my face and upper body from the windshield. (South Texas)
Agree 100% the best is ceramic tint in addition to this cover. Ceramic tint is blocking most of the rays as it hit the glass... the shade blocks rays after it already passed through the glass therefore radiates heat inside the vehicle..
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.
Excellent Maui Jim sunglasses. They should make a sunshade.
Tinting my model 3 made an immediate and huge difference in the amount of heat coming in the car. The clear air 80 tint on the windshield is practically invisible but wow what a difference
I fixed mine by buying a Model S 2016 with a sunroof that can both act as a passive heat reducer in vent mode as well fully open or a variance thereof for nice airflow while driving. The wind shield that raises when the roof is opened acts as a wind buffer that reduces wind noise. Honestly to reduce heat when the car is just sitting in a hot driveway or parking lot is to just let the climate control run and vent right before you get in to drive.
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.
Mike, did Tesla change the glass roof? My 2022 does a better job at reducing heat than my buddies with the 2019 models. Although, mine does not change color when wet.
Did you find any sun shades that have the reflective material? You would think it works do better?
I am also in "N.Cal." We have an 2020 S model with the full glass panel. We have not had our car 6 months and have yet to experience any triple degree days. I can say on an 80* degree day, the glass and car interior gets crazy hot. I tried to go the cheaper Amazon route but the sag was too much. Also had a problem with the clips. I am 6'4". It was just irritating to have that shade on my head. I returned it through Amazon and tried the Tesla brand. The size of the glass matters, you are not going to get away from some sag, but the Tesla brand is taut enough it doesn't touch my head. I also ceramic tinted the back hatch window. Huge improvement. Seems ridiculous to me to be nickeled-and-dimed by Tesla after spending $100K on a car...that is what I find most irritating. These cars absolutely need some shade in the spring/summer. The shades should just be included like the tires are. LOL
Just an idea... wouldn't a lighter coloured sunshade make more sense? Bright fabric should reflect far more light and heat and should thus help keep the interior even cooler...right?
Like your reviews. If installing/removing often, I’d give the Tesla Model a slight edge. If not changing frequently, such as every few days, the Amazon Model would have the slight edge. Thanks for another well thought out given review. 😃
Is his roof tinted?
I was just wondering if he wouldn't have felt what he felt if his roof was tinted.
And if his roof was tinted & still felt it, then getting the roof shade is definitely a must.
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?
Thanks for sitting in a sauna and comparing these products for us.
While I don't own a model 3 (Tesla dream chevy volt budget lol.) I thank you for sweating to bring this information to us. I always wondered how much heat gain an all glass roof has. Maybe next winter you can do the opposite and see what kind of heat loss an all glass roof does. Especially since heating is such an energy drain.
Bjorn uses the sun covers for winter and uses bubble rap as an insulator.
Your test in northern CA is completely different than where I live. Southeast Texas is below the 30th parallel and the glass roof on my model S radiats another of heat. 😢 I need the shade during the day for most of the year.
Where did you store the bad with charging cables and adapters?
FTG I got my sunshade delivered today. About to put them on now outside is over 80 F today.
2/3 of the solar load reduction? What solar load? If it’s the reduction of what gets through the glass it’s one thing but if it’s the reduction of what hits the roof it’s quite another!
Tesla might be absolutely correct or might be pulling a fast one - and be correct both times!
Any chance you can do a video on how to fold those back up ?
The opening left by Amazon brand in back and sag is a no go. Plus the Amazon version is too dark. I mainly want for glare more than heat. I don’t sit in car with no AC on. Front shade is all I desire, again for glare
Ceramic tint will reduce the heat and you’ll be cooler even while driving.
Yup!
How much for the tint?
@@BillOBarr As with anything, it will vary depending on where you are getting it installed. Some places are cheap and others will be $$$! make sure you get it installed from a place that has installed it on Teslas before, as the rear window will be the biggest pain and you want it done correctly! czcams.com/video/bcJ6Xo7ye38/video.html
Your results match mine. Just wish the back window shade didn't sag so much. All my friends are tall.
Ceramic tint is what I would do.
$$$
@@gordon4385 Even more $$$$$
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?
I have the SUMK and not able to see it from the outside. On the ceramic. Be careful. Apparently there are some threads in some of the forums where people coated their roof glass and it shattered from excessive heat. Someone in the comments here mentioned it was a function of the glass that TESLA used up to a certain point, but don't use anymore...not quite sure.
They work very nice in south Florida !
Which ones did you get? I live in Naples.
Well if you think about it, the shades come more in handy when you are driving and not just sitting in your car. At least that is the way that I see it.
Just traded in my 2020 SR+ for a 2021 LR. Took the front Tesla branded sun shade out of my SR+ of course, and tried to put it in the 2021 LR... no go. Doesn’t fit correctly. No clue why as the metal part of the shade isn’t bent or warped at all. Stinks it doesn’t fit. UGH.
Considering all the comments posted so far, one would conclude that the thermal blocking properties of these black mesh fabric sunshades is modest at best. They do offer some additional relief in hot sunny climates, but they are not miracle cures. An interesting experiment would be to obtain some ultra thin, highly efficient insulation, and place it between the fabric mesh and the glass roof. (Google: Aerogel) Although this would probably give good thermal results, it would also block out all light from coming through the roof, thereby compromising the aesthetics of the vehicle.
You started the timer BEFORE you shut down the AC on the first one. So cut down about 5 seconds. Its all the same. Thx for the test. Will keep my money :)
Best sun reflective material is aluminium foil. Why tesla use usless black mash?
Great information! Could you solve the clip problem by gluing them in?
Once you put them in a couple of times, they are not really an issue. The outward pressure from the screen keeps them in place. They really keep the shade from falling on you. I've been using the SUMK for a full year now and have had no issues with clips falling out (except the first time I tried to install it like FTG).
I wish you showed how it looked from the outside to see if it adds a little privacy.
Does this help remove cabin noise? Can you show a before and after decibel test?
I don't need to run a test. This would not reduce cabin noise at all.
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 have the SUMK. Honestly, I don't even notice it in the car and you cannot see it from outside.
I purchased front & rear Tesla sunshades last year. Super happy! In my opinion, they're worth the extra money...Much nicer & cleaner look with a tighter fit, visibility is excellent and definitely help to keep my Model 3 cooler. Also, they do NOT sag; every one of the aftermarket sunshades that I considered sagged quite a bit. Regardless of a person's height, I think the sag takes away from the *amazing* Tesla interior. Good luck with your decision and enjoy your Tesla!😀
Did you have any tint on your roof or you got whatever Tesla provided on delivery?
Only what Tesla provided.
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.
I think the point of the Tesla sun screens are to reduce the thermal load (not completely) to allow for that beautiful view of the panoramic sunroof - the 3rd party sunscreen from Amazon is darker and of course will reduce more heat, but obliterates the view of the sunroof. You said they both sag, but it seems like the Amazon one sags more which would be annoying for tall people in the back seat. I'm not sure I'd want to worry about clips falling off when installing the Amazon brand sunscreens - that must be a pain when they fall on the floor and you have to search around for them. In my opinion, I'd opt for the Tesla sunscreen - the Amazon brand is less expensive, but not ideal in my opinion. When you purchase a Tesla, of course you want to get the best bang for the buck when purchasing accessories, but in this case I wouldn't comprise on quality, ease of installation and can still view the sky through the sunroof. Thank you for your demo video on these screens. I've been a subscriber to your channel since purchasing my 2020 Red Model Y Performance in July last year. Keep up the Great work - from the @RedTeslaGirl on Twitter!
Thanks Tracy! I appreciate the sub!
Oh no i wish Id seen this a day ago Ive just ordered the Tesla one
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.
If leave your car parked in the sun on a 88F degree day the cabin temperature after 2 minutes isn’t the problem. It’s going to north of 110F inside without a sun shade in short order. It would be much more helpful to know if either shade diminishes the maximum temperature after a full hour - if not they are worthless for parking in the sun.
Good point Andrew. I may have to do a followup. No major heat waves in the foreseeable future.
If you are going to park in the sun for any duration of time, you should definitely get a fitted Windshield sunshade. The roof sunshades will also help because the car’s AC won’t have to work quite as hard to maintain the 110° cabin temperature.
I would not expect the maximum temperature to differ much beyond two or three degrees, as there is a point of equilibrium when the heat energy radiated/transfered out of the car is the same as the energy going in. I would expect the graph of temperature over time to show the biggest difference.
David Nizel Most of the interior heat is NOT from the radiant sunlight so the shades are mostly ineffective - the heat is CONDUCTIVE from the massive glass panels and sunshades offer near zero thermal barrier. You could literally burn your hands just touching the inner glass surface on a warm sunny day.
I expect the cabin temperature to reach 110 in direct sunlight on a hot day no matter how many roof or windshield shades you attach. But since neither you nor I nor FTG did the experiment it’s pure speculation. Based on my experience simply venting the windows is more effective (and you save $200!)
JAMFUTUBE That’s exactly why these sun shades aren’t effective. The mass of those glass panels is a giant heat sink that warms the entire car and also the air within. It doesn’t matter if it takes 15 minutes or 30 minutes to reach 110F on your graph. It’s going to reach 110 EITHER WAY and stay that way for hours. Save your money and park in the shade
Hey do you have a screen protector on the screen, if so was it worth getting one. I have front tint and back tint, and clean the screen regularly.
You should have done the 85 degree time test with NO sunshade in place, to see how much something is better than nothing.
doesnt the roof already have tint
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.
Tesla is the best
Where is it made?
Best reason for a sunshade? Dogs! We have an old small dog and even in Dog mode, she is still stressed by the radiant heat. We were really looking forward to being able to get out more and leave the dog in the car. We still have to find a shady spot because of the glass roof. We will be ordering a cheaper sun shade.
