Well done GAF. Even if I don't buy this product whenever I get solar, I love this innovation and am cheering it on.
Agreed. Competition is healthy for everyone.
Yeah. Why hasn't solar taken off in all these years is beyond me.
@@Mark1Mach2 long term investment. How many years does it take to pay for a full house system? 20yrs? 30yrs? And yes it should make your house have a better resale value but a ton of people don't buy a house a 20yrs old and stay there 30yrs which means most can't afford the upfront cost hoping they will be there in 20-30yrs to pay if off and start to save on electric bills. I live in a 1700 total, 480 square foot living house. I am the perfect candidate for solar because I have over 3 times the roof of my living area as non living, (porch, carport, patio) which means I could put all the solar on the roofs not directly over my living but the added up front cost, 20yr investment recoup time, the added home owners insurance, as they are covering more "house", more worries about leaking roofs, damaged solar, inverters, batteries if I want power in a hurricane when the power company is out for a week or 2 here in south Louisiana, to worries about a hurricane tearing them off, cleaning, maintenance, and after 20yrs after I pay them off, now they don't work as good so I need more panels, or they need repairs. So for me it just not there yet but i would LOVE if every roof/property had solar, clean, renewable, free solar, its just not right for me.
Does that really look better?? I think not.
@@markbedard1886 "look better" ... I don't understand your comment. Aesthetically, solar doesn't look good vs a plain roof shingle, regardless of traditional vs. shingled solar. Regarding effectiveness, as I recall from watching the video 3 months ago, the shingle option produces less power than traditional solar but because you can deploy it over a greater portion of your roof, there is a chance it can balance out or exceed traditional solar.
5:40 I'd like to hear more about that -0.35% temperature coefficient. Cooling the underside with ventilation had always been so crucial.
Isn't that worse than the figure listed for the ordinary panels?
@@priestesslucy3299 There is no ventilation under these, unlike a rack mounted solar panel. A roof can become extremely hot. This is my biggest concern and I'd like to see independent real-world results... besides that concern, this looks like a compelling roofing product.
Cooling adds complications and potentially new failure modes. You will make up the difference in loss due to thermal coefficient on sizing. More solar shingles.
@@gipnor All Solar PV generation gets hot. That is why the best production months occur when it is cool and sunny. Here in Ontario, that is March and April. Then, in the summer months, we get sun earlier in the day but by solar noon, all our systems start to lose energy production because the modules get hot.
thats why this was not worth making a video for this, wasted my time watching any of it.
Water leakage isn’t an issue with today’s racking systems and flash feet. I noticed the .55 degradation after 25 years that’s not even in the ballpark. String Inverter technology …not class leading. No. Dollar/watt breakdowns every video I see on this is vague with no numbers. I guarantee solar sales aren’t made without a real world breakdown of how much watts of production are being produced for the cost. This could be a solid product for a niche clientele. There was also no mentioned of cell efficiency. We’re about 2 years from the release of tandem PV technology which will drive panel efficiency to the upper 20s. More efficiency equals choice of more power gen or less panels.
I like this comment. Pretty good points made that we need to be aware of.
Dollar/watt breakdowns are a must in the solar industry. I do not trust solar companies for install because they overcharge on the equipment and recommendations. On top of that most don't even generate the power based off the quote.
Good luck when the insurance company forces you to get a new roof. Definitely not cost effective. You are right about the string inverter. Thats a big downside of these shingle panels. A single point of failure is not cool. And no shade mitigation is a deal breaker. Correct about todays attachments and flashings. Ever try to get a shingle manufacturer to honor their warranty? Have fun.
@@shroud1390 Funny you should say that. As I type this my roof is being replaced after recent series of Tornado and hail damage. I'm becoming more interested in these new rackless mounting options. I'm not gonna get solar for another 2 couple of years so i'm going to keep my options open. I love the fancy metal roofs where you don't even have to penetrate but damn they are expensive and i'm not in my "until I die" home yet.
@@hmurchison8123 standing seam metal roof is the way to go!
Brian Cooley is such a good reporter, I honestly don't even care what the subject matter is...I will watch/read it. Bang on, as always!
Same!
I was just about to say that…this man is a living legend. I was sad when OnCars ended, but now I’m glad he has the freedom to review anything he wants now. He’s definitely the best CNET has right now
@@soiceyboy33 I wonder why he seldom reviews cars these days. He's one of the very best.
Ditto!
Agreed!
@4:35 They cut off the conversation about the Central micro inverter. There is a reason why!
Be warned with only a single micro inverter for the whole roof it will only take 10% of shade on ANY individual Solar Shingle to shut down every solar shingle because they are wired in series like Christmas tree lights.
That means trees, cloud cover another house...all you need is 10% of your roof shaded to get ZERO power
Not really because of "bypass diodes".
All solar panels nowadays have a simple 600V "bypass diode" in their terminal box. It is soldered across the panel's terminals in reverse-bias to the current flow. The diode provides a lower impedance alternative pathway for the electric current of the other non-shaded panels to "by pass" the shaded panel(s) whose impedance has increased greatly due to shading.
At worse, a partially shaded panel will take out just the panel itself and not the entire string. These diodes cost pennies at volume and could even be installed onto very old panels for the same effect.
Some larger solar panels have bypass diodes installed across the rows or cells within the panel itself during its manufacture. This provides bypassing of a panel's internal rows or cells allowing the panel itself to continue providing some power in partial shading conditions.
Not necessarily, there are these thing called power optimizers that addresses some of those issues. And in some cases that’s not much of an issue. It really depends in a case by case basis and what the owner is willing to spend based on having the right information. Saying that a string inverter setup is straight up inferior is something that some salesperson would say to upsell you to a $28K system instead of a $18K system. Every setup has it’s plus and minus and related costs. I’m sure over time they’ll provide more choices and not to forget 3rd party add-ons that may address some of those issues.
This person is wrong. If you shade one panel of a string on a central inverter it averages in a ZERO out of how mnay panels are in the string and bring them all down, but NOT to zero. Micro inverters go on EACH panel. A central or string inverter wires in series. Microinverters are made for shaded situations and dont have a single point of failure like central inverters.
@@SunnySTX These are wired in series. They don’t have inbuilt micro inverters on every tile - that would be cost prohibitive and a maintenance nightmare.. There may be a microinverter in the fiberglass box at the end of each column but I think they are designed to go back to a normal string inverter as there are no microinverters that I know of that could take the wattage (45W per tile x say 20 = 900W) and potentially you could have as many as 30 in a column. Also the installation they show on their website has only one fiberglass box on the central column which means it’s more of a junction box designed to combine the strings. I’d assume this system would need bypass diodes on every panel and blocking diodes at the end of each string.
@@mondotv4216 they're 14 watts per shingle. String inverters run at 600V per string on residential so you could have ~28-32 in series based on climate thermal coefficient rating for location for MPPT operation.
I'd still want rack-mounted panels. 1. Have microinverters, 2. Potentially run cooler which reduces efficiency loss on hot days.
I think it comes down to cost ultimately if it's half the price 60% the efficiency would be acceptable
@@boblatkey7160 like I said it depends on the cost. At this point there is no public information on their costs. So we don't know what it is. My point was they would have to undercut the total cost significantly to be viable.
I like the idea of being able to nailgun the panels to the side of our camper because of how lightweight the panels are... We've only got so much room on the roof.
Don't put holes in a camper.
Just don't.
For a camper you glue the flex panels to the roof or you have a rack that takes existing bolt holes, replace with longer screws (maybe the same screws) and reseal with the RV sealant.
You CAN NOT EVER seal up the penetrations as well as they did at the RV factory. (and they have issues sealing them up)
Better off with a rack system that slides into one of the storage areas accessed from outside, set it up and clamp it to the bumper.
For just the 12V systems of the RV, you can do fine using a Harbor Freight 100 watt system.
(plan to need to attach it to PVC to join the 4 panels and then weight it vs wind.)
The Harbor Freight set is what I use now, screwed to a pallet,with the spring bar hitch system laid on it for weight so the wind doesn't blow it over. This has held up to 60 mph wind gusts. 28 ft bumper pull that will sit in one place most of the time.
I have a utility trainer with 2 of the old 45 watt Harbor Freight panel sets mounted. Appx 11 years and still works fine. (pretty good results from that experiment but i wouldn't mount them to the trailer if doing it again. Separate and able to be angled wins)
Flex panels glued to a CLEAN RV roof do fine. Not as efficient as panels you can angle to the best collection angle.
Just putting them to 30 deg pitch pointed due S is an improvement for most of USA. (compared to flat on an RV roof)
@@fhuber7507 you're right. Actually I used a caulking gun for the cheap panels we have on the front. We don't own a nailgun, only a caulking gun
@@fhuber7507 either way, it would be impossible to caulk the cheap ones we have now to the wall. The lightweight panels would be way easier
If it has an awning perhaps it could be used there.
As a solar business, since 1977, the most practical placement of solar panels is building a covered carport.
It’s easier to service and the entire structure qualifies for tax credits.
The yard is a good place too
Can’t seem to find any that would look good in my driveway.
but wont the shade of the solar panels on a house help cool the house down in summer?
@@steviegbcool
Not very much.
I am sure the tax credit angle is a great sales pitch but hope your clients dont get audited.
Optionally add heat pipes on the backs of these to: 1. cool the PV cells, 2. provide heating and/or hot water
There are panels that do just that, look at Linus Tech Tips video. (For the panels/entertainment, not as much for solar.)
Cost
@@user-dr2pg8fk2i Thermal inefficiencies will cost you more. Heat pipes will keep the cost above standard panels.
@@dundeemt multiple companies have looked at cooling modules. None of them have done it. What have you figured out that they haven't?
There is another advantage that they don't talk about.
I ordered solar panels for my roof. They add weight to the roof and therefore that requires an engineering review and requires that your city or county needs to sign off on it.
From a structural engineering point of view there is no additional load vs. shingles and should not require extra structural engineering scrutiny.
My project has been delayed by my city for a long time due to the City engineer's questions and requirements.
Your city sounds quite inconvenient I have just ordered panels and I’m going through none of this.
Hahah do you have to ask for permission to flush too?
Version 1.0. Concept is great. Give this company couple of years and they might do product updates in 2.0 to bring costs down and efficiency up.
Yup, plus other shingle companies releasing competing products. Pushes quality up and cost down as they compete for our business
For me now I don't care about design, colour and all those specs.... price is the most important thing. A company able to provide low cost solar panels will easily make a killing worldwide.
The thing is, it’s not just the price of the panels. You can even buy these in Ikea these days.
It’s other things, like the convertor which needs replacing every 10-15 years, that makes solar too expensive still.
Efficiency, longevity and durability is important too
Most important how much it cost and what is the output W/m2
Ok checked the website and no public info about price or output...
If you choose a white roof shingle to have a 50 degree cooler surface temperature over darker colored shingles, this will be a oven for the attic. I'd like to see what in attic heat blocker they come up with.
Imagine if every home in the sunny states of the West (California, Arizona, Nevada, etc) had roofs that were generating solar electricity. Game changer right there, never mind about the rest of the country.
More over, all those homes could generate more electricity than Hoover Dam, meaning we remove the dam and return the Colorodo River back to its original condition.
Yet the power companies (AZ) fight us at every step and destroy nearly every incentive to go solar.
All shingled roofs all over NA. not just the sunny states. This would be the ultimate in DG.
@New Moon The price will have to come down a fait bit before It becomes a good investment where I live, It can't come soon enough though.
@@valkyriefrost5301 Wait what about the water supply
I'd worry about heat and longevity compared to regular Solar panels.
they casually threw the concept of 25 years.
@@ehombane But 25 years is typical for that style of shingle roof? Solar always uses 25 years and with efficiency gains, putting a new solar roof on in 25 years will provide much more energy or the homeowner will still have working solar and only do what is necessary for making the roof new. My roof is 20 years old in Phoenix and I am pulling the shingles soon for new felt which is normal. My so,ar adds to the cost of the job (about 20%) but I will only have my solar at the end and not brand new solar with the benefit of years of efficiency improvements. ~I hope this new product succeeds. It plus storage will be great for homeowners.
In my region, *the fire department will not fight fires of rooftop PV installations* simply because of the risks for the firefighters. No "excuses" needed - just rational thinking applied.
Hi FD,
Miles from the video. This product passed an electrical hazard check with zero hazard. That was a panel that we electrified, broke, and tossed into a tub of water. The fire departments said we were the first to pass with zero hazard.
@@milesproctor7392 Maybe READ my comment first before freaking out...? You are miles away from what I am talking about. Here is a little story for you: a friend of mine gets to test drive cars for top car maker in the EU where he works in development. Their combustion models now have "emissions" that are CLEANER than the air that goes INTO the system. He is still fined for "pollution" when he drives to a business meeting in Antwerp - simply because the administration of Green Technophobes can't wrap their head around the facts of chemistry and physics and are putting his hi-tech vehicle in the same category as a diesel lorry from the 1950s based on outdated criteria. *And that's precisely what I am saying: Firefighters and all other bureaucracy are thinking in categories = simplistic patterns, not actual facts.* - and my comment is highlighting a problem with just that: categories. ... as for excuses: in my area, we also get taxed on the electricity we make, even if we don't feed it into the grid! Again, no excused needed - just basic maths applied.
Brilliant product. Needs to be globally launched.
Big problem with these is they are plastic panels and the sun deteriorates all of these plastic panels within 3 years and will only get 50% output. At 6:00 minutes in this video they deceive you by showing a output decline of 2-25 years of 55%. I guarantee that 55% will be at the two-year mark. Anyone in solar that is honest will advice you to get glass panels.
The only advantage that rack mounted panels have is this: they can be installed on roofs that don't face the ideal angle/direction. Although less attractive, the panels can be tilted to maximize output. Since my roof faces due south, *I WANT these shingles* !
Eh, not quite. A west facing roof can't put south facing panels even on the best of rack mounted systems, and the vast majority are still going to be angled the same as the roof. Now in flat roofs then sure you can rotate and tilt as much as you want. The biggest benefit of rack mounted panels is the use of micro inverters in case you have cobble together panels with different angles on them. If you have a south facing roof then these panels are a good choice, not cheap mind you, but if you were going to pay to have your roof replaced AND you were going to pay for solar then this definitely is a good solution.
@@Mike__B I guess you missed my point slightly. Not all homes are built on a 'grid system' where streets run north/ south and east/west. In a lot of meandering suburbs, plenty of homes face slightly less than ideal direction (eg: SSW) and the panels are tilted on the racks to make up the difference. Although this looks less attractive, some people would rather have better performance from their panels over how it looks.
That said, I agree with the other points you made.
@@marceld6061 No I understood your point, I'm just saying rack mounted systems typically are not going to orient themselves in a different direction to maximize sunlight exposure, much like these shingles they almost always will be facing the same direction as the roof does.
@@Mike__B Where I live (west coast) and where I have travelled (Hawai'i) I have seen more than "a few" that have the panels adjusted to point in a more ideal direction when the house doesn't face due south. The panels are not on a flat plane. They are all tilted. Majority are parallel to the roof. That can be because the roof faces the ideal direction or it can be that the homeowner wanted a uniform look or it could be that the estimate for the installation was too high with having each panel tilted. I have had homeowners can make "less than ideal" decisions based on budgetary constraints during my many years as a contractor. The additional cost of orienting the panels during installation would probably pay for itself in energy return. But that extra few hundred bucks up front can sway decisions.
Great concept - very practical - I see more room for improvement in eliminating the majority of rooftop cables , connectors, and connector housings with flat interlocking buss bars or similar locking tabs.
what I was thinking.
heck just a heavy guage solid copper wire that snaps in a track on each one would eliminate the clips
Need to improve efficiency and temp coefficient greatly to be viable
@@chefgav1 nah, as long as cost is low. There is room for poor efficiency if it's affordably baked into the roofing product
@@ctgottapee But the guy at GAF didn't say it was less expensive than rack-mounted panels. Same cost, less efficiency, hard "No" from me.
How do the home insurers feel about this? Will they pay to replace these after storm damage or just pay the value of an equivalent standard shingle roof? Are premiums inflated to adjust for that?
Ask insurance company!
It's going to be a lot harder to keep these panels cleared of snow than raised panels. Also, the slope of roofs are not always optimal depending on latitude and time of year. Raised pannels can change this angle for greater efficiency.
I'm not quite if it's snowing, solar panels would be that effective at all tbh. I think this is more meant for dryer climates like California, Arizona, Florida, Texas and the lots.
@@tonyli2918 In dryer sunnier climates people ran out of 'excuses' LONG ago.
@@tonyli2918 I'm watching this video from the south of France and je suis interested by this new technologie !
That is mental that such a low percentage of roofs get solar. We re-roofed in Northern England 2 years ago and got black in line (where the panel is the primary waterproof layer and the roof membrane the secondary) panels fitted into the roof. It cost around US $10,000 for a 7kw system and it saved about $5000 in slate cost, as less slates were needed. We don't even get much sun in Northern England, I have no idea why so few people would consider solar. This system looks good.
$10,000 is alot and the ROI isn't that good.
I played 1450$ for 8 530w half cut solar panels exactly a year ago
This is absolutely bloody brilliant, extremely well engineered. THIS is American manufacturing ingenuity, this earned a like and subscribe!
They could easily incorporate these into building codes. Require every new home built to have enough solar to power the house plus 40%
My biggest question isn't if it's "weather/wet" proof... How about how good is it in frozen rain, 20 degrees below zero, and heavy snow? That's where I can help make a decision with Midwest use
It's a solid state high density silicone design, aka, itll hold up better than shingles due to being more resistant to thermal expansion.
Also since it's not rack mounted, load stress along the mounting points is non-existent as the weight is equally distributed across the entire roofing surface rather than a few clamps.
Aka, these are almost better in every capacity from a structural standpoint. Although I doubt they'll be anywhere near as efficient. Thoigh I would argue that having smaller, panel a which require less resources to make that are more widely adopted, is more important than squeezing out every last drop of efficiency.
Also because their directly on top of the roof, I wonder if the thermal mass of your roof can actually provide some cooling effect considering homes are air conditioned. It would be amazing if that actually lead to greater thermal performance over rack mounted panels.
That’s a good question I’m going to venture a guess they definitely tested in different temperatures and weather conditions I’m sure there’s probably a good amount of loss of efficiency with it how much is obviously something you would probably have to contact them about but I would venture a guess that you could use this on like the East Coast for example if it does work with all those things mentioned I must admit I would definitely be most impressed with this as far as solar power goes definitely the best all-around I’ve ever seen I think out of all the different companies and adverts including Tesla
I'm going to guess this product is not meant for the top half of the US...having panels buried under snow for half the year is pointless.
@@glamdring0007 Even on the East Coast in the areas of like Buffalo in Syracuse to get some of the highest numbers of snowfall the roofs are buried under snow continuously few days at most
@Zolar Czakl That’s what I thought I was like when they actually do okay during the winter because they’re not losing energy from being overly hot it would actually help them run better kind of like computers when I keep them in over refrigerated room for servers they run better being colder than if they were at room temperature. Just like a lot of people ask what about if you live in someplace like Seattle or Boston where it rains all the time it is cloudy it’s like yeah you wouldn’t get as much energy produced but you would still get energy you don’t need it to be shining son like Florida or Arizona or something it just wouldn’t be quite as effective but it would still work and people still have them in those areas in the technology will only get better and better every year
The video talks about the loss of .035% coefficient starting at 77 F, and increasing as the temperature increases. What is the loss at 90 degrees+ that I get here is south Florida? How much does that affect the production of power?
Its .35 not .035 huge difference. It will lost about 6 to 13 percent at peak heat ( .6 to 1.3 kw in a 10k system) my concern here in florida is the wind resistance and insurance premiums.
Why not glue the panels on to a rubber canvas like pondliner, u can cut that to size for any roof. And that lasts same 30 years. Can be underwater (like 2inch or so for better cooling. )
Metal roofs can use bracket systems that don’t go through the roof thus avoiding holes. The brackets tighten down on the metal ridges and connect to rooftop solar panels. Best option in my opinion.
Standing seam metal roofs are the best.
Absolutely brilliant! Great idea. I would buy it in a heartbeat if they were available where I live.
Got to give it to this seller. He got it all right: articulation, expertise, language, all the checkboxes. The product seems great.
Good report thank you. Extremely interesting product.
The "Vacant Walking Areas" he mentions at 5:45 is actually a Fire Code requirement to allow Firefighters access.
Haven't seen anything to indicate that Timberline is exempt from these requirements.
That code is too ensure that firefighters can access as much of the roof that they need. Rack-mount solar panels are brittle and because there's no support under the glass, they will break if walked on, but these are unbreakable, so because a firefighter could walk ON these, rather than having to go around, these would be way better from a firefighting point of view.
I enjoyed the video. How hard would it be to change out a panel when one fails? Thanks Mike
I like where they're going with this technology. Looking forward to future designs with integrated seamless connectors.
Once they get the cost equal to a standard roof install, I'm going to order the system. Heating is always another huge factor.
Im not an expert but I think you can apply for some or of government assistance or premium loan if you decide to get those even now. It depends where you live and the local laws ofc, so take my comment with a bucket of salt but it worth to check if there are some programs or bank premiums in your area.
Why in the world would they ever get it equal to a standard roof?! It’s a solar panel not a hunk of tar pressed together. As soon as Ferrari comes out with a car that costs no more than a Corolla I’m gonna buy one.
Great idea for a product that should only improve. I do wonder about the cost but solar is always a major investment. I have no doubt they can eventually achieve cost parity with normal panels. I think the others will be copying them because if these last they're the obvious choice
Very interested to learn how this system will hold up to hail.
I love this idea. I still want to see test results from homeowners.
This is the part that almost makes me conspiratorial, because all the ads about 'gamechangers' (I see three of them) just makes me 'want to wait a little more'. However, I had always heard the roof is the least efficient and you should have tracked panels that move with the sun. But they almost NEVER actually talk to a person that has them, that shows the bills showing how much it has saved. I almost think its fossil fuel companies doing ti to make people wait just a little longer.....which is usually til gas prices go down.
@@mikearchibald744 a janitor at my store got some for his house over a year ago. Just solar, no batteries. He said it has replaced his electricity costs so far. He doesn't pay for electricity anymore. Only the monthly payment for the panels.
@@trinsit Well, yeah, the question is how many panels and how FOR the panels instead of electricity. If your payments for the solar are the same as electricity, you are no further ahead And if there are NO batteries, then what happens on cloudy days?
@@mikearchibald744 you do come out ahead because now there is a point at which the bill stops when you pay the system off. Also, their house is still wired into the city electric grid and power is continuous. It's just that while the solar panels produce electricity, the meter moves backwards.
@@trinsit I see, so he does net metering and supplies enough to the grid to offset any payments. They have that system here too, thats my main complaint because IF the utility would actually PAY for the power then tons of people would invest in creating power. BUt all they do in most places I've checked is balance the credits at the end of the year and you may owe them, but they never pay you, so essentially they are STEALING power from you.
I was recently informed by a GAF solar shingle installer that I must have my entire roof shingled when this product is used or else GAF could not offer a warranty.
This was a problem for me because only 6 months ago I had one side of my house re-roofed (Owens-Corning) due to leaks, but now that I am ready for solar I would be required to re-roof that side again - only this time with GAF - before I could get a warranty with the GAF solar shingles. It's all-or-nothing with GAF.
Wouldn't it be best to keep an air gap for heat issues in the attic? If someone choose white shingles to benefit from the 50 degree cooler roof surface temperature 🌡️, this product is an oven.
A version of this for RV's would be great.
Not a useful application, roof space on an RV is very limited, you want the higher power per square foot of the fixed panels.
Though a flexible solar panel that can be rolled up would be a game changer as an awning upgrade.
This is a good step. Keep up the research.
I like that Brian corrects the solar guy for his incorrect use of inverter terms. Central inverters aren't used in residential settings, string inverters are.
I think he was clarifying more than correcting, but yeah it’s impressive Brian knows all this stuff too.
This is a great product. Now, you need to get the price down to a reasonable amount.
That's done by producing and manufacturing with the eccomies of scale. Mass production reduces cost tremendously that's why the assembly line made car ownership possible
Where did you see the price? Someone mentioned about no price on the website.
@@dannydaw59 he said that is equal to roofing and an similar sized solar array. The only difference is that you can walk on it and is not risk of damaging the roofing with the bolts.
@@ehombane The efficiency?
This is great. Thanks! But it would be more comprehensive if it covered recycling as well.
@D R This isn't a typical solar panel. Traditional solar is made with more components, much of which could be recycled. This uses less material, but is it more or less recyclable? The more panels that are out there, higher the prices and/or incentives can make recycling viable, generally speaking.
Great product, very easy to install and looks great on the roof. I also think they have less chance of blowing off in a storm because the wind can not grab under it like a traditional solarpanel.
If they blow off thats a really bad day your whole roof would fly off..there rated at 150 mph of wind
@@brianguirola4219 yep. We had all our installs survive a cat 5 and panels only got trashed from trees. Not the wind. All this stuff is engineered and will def meet any windload codes
I am really impressed with this! Making solar an easier thing to interact and integrate into existing roofing businesses is always a good thing. My only concern is durablity to hail. You are doing great, does your company have a social media presence?
The parent company GAF is a pretty big company. Not a startup.
its walkable, so im guessing it should stand up to hail.
The question with hail is, how big, how dense. Most GAF products and 30 yr laminates in general do great to 1” hail, however we start getting to 2” and above, it’s likely damaged. We get to 4” and bigger, not much out there for roofing that isn’t going to have some sort of damage.
"Ugly" - yeah that's my biggest gripe with solar panels. Whenever I fly over the buildings where I live, it's just nasty...
(To anyone who thinks I own a small plane and am serious: I don't and I'm not.)
That is sounds great. I am in the Solar industry as a service technician always consider after installation servicing and Remediation.
If the vast majority of the industry is not in line with this scope of work you will be stuck with a niche product that no one will like to repair and service if needed.
Love it. How do they compare to regular shingles in regard to fire?
Seriously look into it. Start with the alternator magnet version of self running generators. Then combine that with the power wall. It will put out clean energy 24/7. Especially in energy effecient homes
CNET, Please bring back Car Tech, that was the best car review video on UA-cam
Great technology that has a ton of thoughts put into it. Bravo!
I wish they had showed the finished product of that guys roof
Hoping this will be available nationwide soon, as I haven’t been able to find a company that offers this yet in NH....
Very informative....this channel is awesome❤
Looks great, hope it takes off! One way or another when I eventually have to redo my roof I'm definitely going in on this or similar, despite what will likely be modest energy gains living in the PNW.
I think I read somewhere that in climates like in PNW even with total cloud cover, just the daylight will produce power though much reduced
I sell solar full time in Oregon and Washington the pnw is VERY solar capable
Amazing! 👏
I would love to work for/with GAF.
I used to sell solar, and would have to say to clients " you could almost eliminate your$87.00 a month average bill if you purchase this $24,000.00 system, if it lasts 20 years".
So it pays for itself in... 276 months (23 years) and lasts 20 years?
What. A. Bargain.
The downside is the lack of ventilation behind the cells, which will decrease efficiency on hot days and because it's flexible, the durability might be an issue too. I will go for cheap regular panels even if it is a bit more effort to mount them on the roof... It's crazy how much power you can get out off your roof nowadays...
How do you repair or replace a panel /microinverter when it goes out? If one of the micro inverters goes out will the system continue to function since it's based on a string inverter?
A great answer to all the issues that grew from Tesla’s troubled technology that was rolled out a few years ago. Excellent 👏🏻
Brain got a great demeanour which shakes things up nicely for audience to enjoy even for ordinary stuff.
I still like the idea of the Tesla solar tiles best since I always loved the look of Italian terracotta roofing
Wait do you mean the solar roof tiles on the fake houses, on the fake street, on the movie set at Universal Studios (Desperate Housewives)? hahahahaha!
How is shade mitigation done? Are the panels connected in series or parallel? A central, single inverter usually has shade problems.
Great job! GAF I will be keeping an eye on this system….
somehow i dont think thst the homeowner paid full price for the solar panel and install
Why?
So what they fail to tell you is that it can’t bet used all the way to the edge of the roof, nor can they go around any cutouts. Because of that I went with a rack system. Difference in power creation was ~50% difference.
What’s there life span how what issues are there with snow load what elec issues are there how do you prep valley’s can you install on low slope
what's the cost per panel (not installed)?
Regular shingles are installed offset so the overlap seam is covered by a solid span. Because of the wiring lining up there is no overlap so the seams are all lined up. That can't be great.
Excellent review, but I don't think it improves the look over traditional panels all that much, but certainly better than the older silver anodized as seen at 7:21. GAF really needs to make fake panels that match the solar ones and do the whole roof in one style instead of this weird mismatch of smooth panels with what looks like raised seams and architectural style shingles 5:45. Obviously the efficiency isn't as good at 14.5W/ft² vs 21W/ft² for panels and that's fine if you have enough space, but I really wonder how well they handle typical issues like shading, etc. They don't appear to have any type of optimizers built in to each panel and they admit, it's a traditional string inverter that relies on every panel producing the same to get output. Typical issues we have in the NE is snow that builds up on the bottom edge of the roof. It seems like you'd get no output if just the bottom row was covered since all the cells are in series sideways. I'm sure they will continue to make improvements. Another thing that would be nice is to make a ridge vent with an integrated junction box and run the wiring caps all the way up, so they look like they are part of the roof style instead of a cover that tries to hide the wiring. I like that critters can't get under them, that's a bonus.
Exactly, they conveniently gloss over a lot of the issues. This is more like a add for GAF then anything else.
While the "shading issue" does apply, so many houses have been built over the past three decades with zero shade, that the issue does not apply too many consumers. Of course, the real question is cost and longevity.
@@valkyriefrost5301 What does apply to a lot of customers, at least in the north of the US, is snow. For example, yesterday it dropped about 2" and by noon, the snow slid down and stopped at the asphalt shingles and covered the bottom set of panels of my house. It's still there and the rest of the panels are producing electricity just fine. Also while I recognize many areas are different regarding shading and trees, by me, it's required to have at least 2 trees in the front in any new development. And while those 2 trees were shorter when I installed solar, they now shade the bottom row at times which makes no meaningful difference to my annual output since only 2 panels of 36 get shaded.
@@scottkolaya2110 - I was not saying that this solution would apply to every home across the US. Only that many homes are built is treeless communities, especially in the South and Southwest parts of the country. Other situations, like yours, will require more a thought out solution to be viable.
@@scottkolaya2110 The reason while your not covered panels are still producing it that micro-inverters are used. GAFs string inverter, by contrast, would mean the inverter shuts off when not enough panels are producing.
If one panel/shingle goes defective or is damaged does that essentially make the whole solar collection system stop working?
What’s website for this cant find on google???
What a brilliant product! Everyone should get this!
Wonderful innovation GAF! What is the wind rating on these?
The issue here in FL is you need a new roof every 10 years. Insurance will cut you off when roof is over 10 years
I'm worried about the durability of the overall unit and fire protection/flammability of the product.
On a standRd shingle roof when you get to the ends and need to cut the panel so it does not go over the edge how is this done. Since they do not seem to overlap
Problem i find is that what if one goes bad? You can’t just yank it off since its nailed. Yeah a roofer can come and do it, but you are removing a shingle and then creating more holes to re-nail it. On a wrack you just screw it off and your good to go.
okay so now that this idea exists, can we then put a perfermated pipe at the top of the roof to trickles cold water down to coll them. then collecting it in a tank and pumping it back up. this can clean and cool them and maybe offer some warmish water for the house. And if any embers falls on the roof during fire season then it will take care of that too.
Way to Complex for the mass market. As an option it might work. It makes it more difficult to get to the break even point.
@@fatboy19831 didn't seem so, the water pump would be small and the roof area very large. Plus the efficiency boost. Also water is very good at absorbing heat and is able to bend light into he panels from non direct light should that be relevant considering it would a thin film. Your tank then would then also be able to collect rain, which means less demand for central water too and be covered to stop evaporation. So I do t really see a problem. Or a complexity issue...what complexity?, especially with things you can get at home depot easy.
@@fatboy19831 if they provide the shingles and install them then I can build the rest in under a day. Whats to difficult toassproduc3 about this? Are people dim?
How do these meet the NEC 2017/2020 panel level shutdown requirements? I'd imagine having to purchase a per-shingle tigo (or similar) optimizer / shutdown would be even more prohibitively expensive and break the aesthetic benefit. What are the per-panel wattage output and @ what voltage? How is grounding handled for all of these shingle sized panels?
I was also looking for the answer to this question. Maybe they are loopholing it, and calling the whole array one module with a single rapid shutdown immediately under the roof surface.
Why is the industry so obsessed with putting these over rooftops? If they did it as a pergola, gazebo, or carport, they could just mass manufacture it as a kit for cheap installation and avoid the structural risks.
It would work for most people. More than the fraction of people who happen to need a new roof this year.
Haven’t seen a video of yours in a while. The sliver hair looks good on you Brian
How do you get these shingles? Web page not user friendly
Link to the company would be helpful.
Just did my roof last November wish I had these available
Sounds great…… given the wildfire problems in the US how is the flammability?
What holds it down from the wind lifting it up? Butyl tape? or is that just to stop any wind driven rain from getting under?
In the UK the use of coolant in the solution means no one will service it or any part of the heating system (looking at you British Gas).
From where i’m from, solar panel have to oriented to the south to optimize daylight. What do we do if the roof slope doesn’t match the south direction. Would it be efficient?
How is it that this amazing technology does NOT have waaaaaaay more views?!
One more thing for the roofer to screw up.
Will they install your solar panels like they install insulation?
Home owner - "Hey can you guys put some insulation in my roof while you have the decking off?"
Roofing contractor - "Sure, no problem." Opens up roof, throws in a bundled bale of insulation, and closes the roof without ever "installing" the insulation.
Neighbors - "Hey, nice solar roof, have you noticed any difference in your electric bill?"
Home owner - "No, not at all, and my heating and cooling bills are still high!"
The only problem with GAF is that they won't talk to potential installers, or resellers. I don't know if they are operating out of some sort of archaic dealer network or what, but i've repeatedly tried to reach out to them for more information.
Cool! What's it called?
Well done GAF for employing and putting forward the kind of person we saw here explaining their product. Knowledgeable, enthusiatic, knows how to listen also 👌Another plus for their product 👍
The biggest thing holding solar back is people thinking that they should get paid the same for juice they are putting back into the grid as they are for getting it out. The power companies are definitely not paying retail prices for the power they get from coal, so why should they pay that for solar from homeowners? They are the ones who have to maintain the grid and manage all of the new sources to try and maintain smooth reliable power to everyone else, and that ain't cheap.
Will I need to replace my existing roof before I put on these panels?
So far not sure if it was said in the vid, but if those connection cables are bare that might be an issue in some places. It might be good to have something like a housing that covers those connections that line up would be a good idea even for just a piece of mind factor, though having these housing able to be popped open for quick checking is not a farfetched idea.
I will say this brings the idea of basically making every roof or a home or business into a micro-generator more possible or plausible to come into effect. Though the other side of the issue is well updating the aging grid system to be able to handle that much power transfer both from homes, but also from the power plants across it. An then the last problem less than issue is well the fact that the profits of the entire power generation companies potentially would drop alot if you had that many people generating an sustaining from such a system.
How many years before the roof tiles will need to be replaced?
Sounds great, but how well do they stand up to hail? Will we have a huge repair bill after a hailstorm?
