This video really shows the advantage of having somebody familiar with the system being able to point out tripping points with an install.

[@markmuir7338]

Probably not an issue in the UK, but in more southern climates with higher insolation, panels overheat - which causes their efficiency to drop significantly. Natural convection between the roof and raised panels has a significant cooling effect - which is missing completely in an in-roof installation. Not sure of actual numbers though.

[@ttkddry]

You are right, heat soak is an issue with rooftop installations and efficiency drops with increasing temperature, even for installs here in Belgium which is not exactly a tropical location. If you have ever spend time on a solar roof around noon, you will attest it becomes unsufferably hot, you can see the hot air mirage where the air seems to be vibrating. On the other hand, these hot periods usually correspond with lower demand for power and lower feed in tarrifs drop because of the excess PV supply anyways. If your system is overdimensioned to accomodate for lower production in the winter it should cope... It will get hot in the barn for sure....

[@mrtechie6810]

Correct

[@w8stral]

Well no, just means your installation without venting below was CHEAP.

[@russellmoore1533]

Solar panel outputs are rated when the panel temperature is at 25c, it is rare for panels to be that temp' when there is full sun, especially in summer. For every 1c rise in temp' the panels derate about 0.5% (it varies from brand to brand). It is not unheard of for panels to reach 70c in the middle of the day in summer, so you lose about 22% of you rated output. at that temp'. Having zero air gap under the panels will not do much to cool the panels. They may look good, but are a failure in the cooling stakes.

[@mrtechie6810]

What we need is solar hot water that is preheated by the PV panels, thus cooling them.

[@antoniopalmero4063]

Not everyone has the uncapped budget of this particular customer . My 3.2kw solar array , 7kwh lifepo and 3.6kw inverter cost me £4k . My electric bills have dropped to almost zero whereas i paid ~£3k last year .

This is the future to this area. Makes the most sense, and then design the roof structures around the panels to optimize

[@garywynder]

I've just been involved in helping to install a 1200 panel Solar Panel installation on a big factory rooftop area of the English Provender foods Company over on Greenham Business Park, in Newbury, Berkshire, (for the last 8.5 weeks until today), which included 598 Optimizers (SolarEdge), and four Solar Edge inverter units, and so I understood this video quite well, and found it to be especially interesting to me. I also worked on a new-build 29,000 panel Solar Farm (back in 2014) on the outskirts of my village in Oxfordshire (for 4.5 months), so I've learned quite a lot about this sort of stuff at first hand.

[@anthonydyer3939]

Top tip: Always supply 1 spare panel with an in roof system. Why? Because if a panel goes faulty, while it might have a warranty, there might not be any obligation to supply an “identical” replacement panel. Most likely you’ll get a “similar” panel in terms of performance, but it could be different height and width, at which point it doesn’t fit the tight tolerances of an in roof system. On roof systems don’t have this problem. If your replacement panel is too big, in most instances it’ll fit in the corner of the array and just look ugly.

[@aldozilli1293]

My in roof has got a contaminated panel and the installers warranty has proven to be useless, basically say I have to speak to the manufacturers in China who charge ridiculous amounts to supply and ship and installers charge labour to replace it. Useless warranties are no doubt par for the course so a spare panel is good advice.

[@markmuir7338]

@@aldozilli1293 Warranties are useless. I have two on-roof solar systems (my energy needs increased when I got an EV). The panels of the first were from a Canadian company that went bust shortly after. I learned my lesson on the second, and went with LG. Who then exited the PV business and my warranty is now also useless. Thankfully only 3 of 24 panels are underproducing, and I have microinverters so none of the others are affected. Given difficulty in finding visually matching panels and labor costs, it's pointless to replace individual panels.

[@mattbrew11]

[@seamussheehy8380]

Would counter battens be better for the ventilation of the panels and ventilation for the roof to remove condensation.. If air can get in it will dry out any small water leak imperfections/condensation if the customer applies insulation inside. A ventilated roof is always going to be a better job. .

Great install! Dream setup! Would hate to have to replace a faulty panel im middle though 😂 looking forward to deep dive members video!

[@antronx7]

It should not fail completely but operate at reduced power where optimizer can correct for that. But it looks like it will be easy to bypass it with a jumper wire if necessary. If few panels do end up failing completely the system can still operate at reduced power until multiple panel replacement becomes financially beneficial.

How hard is it to replace a panel in the middle in the roof if one fails or gets damaged? It seems the interlocking would make that a challenge, although this video didn’t show enough detail on the side to side connection to see how that is done. Maybe just have to remove one vertical “column” of panels to get to one in the center if you have more than two longitudinal rows of panels.

GSE in roof system is much easier for repair work if an issue occurs.

[@Umski]

I quite like the idea of this - my poor installers had to repair/replace a shedload of slates on my on-roof install about 10 years ago - when the roof needs replacing this will be a no-brainer if I can get it past planning. The downside I can see is there is no air gap for cooling - likewise with the optimisers being under the roof - however replacing them would be far easier in the loft 👍 I’ve had the misfortune of replacing one recently although it was one of the easier ones to access - otherwise it would be a full scaffold job 😮 This in roof system looks solid but a bit too finicky for clumsy trades to fit and make a hash of the weather tightening, otherwise looks neat 😎

[@videogalore]

Really interesting, I do have a few points - 1) The risk with solar panels onto a roof is typically wind uplift, not weight increase. The in roof systems avoid this as they are not making a sail, so you're right that it might avoid needing a structural engineer, but not necessarily for the reasons you state here. 2) I can't say that I'm too impressed with the Viridian system between the upper rand lower panels and I don't see why they couldn't have made a flashing to sit over the frame of the panel below so that there isn't a channel between the upper and lower panels - moss and leaves will love that gap! 3) It would have been worth fitting panels to the North face as well. The need for panels to be due South is overrated and if anything they will get far hotter which will reduce the performance, so North facing panels would then pick up the slack. These could still be limited by the inverter if needed to keep the output below the 4.5Kwp cap on a single phase supply. Seems a missed opportunity.

[@s0012823]

I really agree with point 2, not too impressed with this system. Build up of moss and dirt. But also the waterthighness is a risk over the years. Is it watertight when 10cm's of melting snow lies on top of it or will it seep through? No offence by the way, because I think it's hard to design a in-roof system that will function flawlessley for 25 years.

[@jayriddo3010]

There's no channel between upper and lower panels, they have a joining strip with an 5mm wide upstand which allows for water to drain off into the drainage channels running vertically and prevents any build up of leaves, moss etc

[@videogalore]

@@jayriddo3010 Take a look at 9:22, there's a channel formed after the joining strip is inserted between the panels. I appreciate that it's only the upstand thickness on the edge of the panel below, but say that's 10mm deep then you've got an awful lot of water accumulating and as soon as there's some bird mess in there it'll be well on the way to an eco-system by itself. It'll be fine when it's new as the water should shed to the sides by itself, but I can't see it ageing well once there's some dirt in the grooves.

[@xXdnerstxleXx]

I really disagree. I mean sure when you live somewhere hot like Arizona you want also a north facing roof. North facing roofs are however, beyond idiotic in most places. For reference, New York and Madrid are on the same level. Europe is much further up north than the US. North facing panels in the UK, with it's gulf stream mediocre weather, mild summers, mild winters, barely any northern sun hours, is the biggest waste of money one can make.

[@replica1052]

[@Hybridog]

Curious about the horizontal battens. When water gets under the tiles or panels it runs down and hits a horizontal dam. How does the water exit and how does drying happen with this system? Is the roof fabric draining the water?

[@jamesfisher4309]

surely battens are always horizontal, and any drainage required happens in the dips in the felt between rafters.

[@easbyenergystorage]

i found you install the panel in sequence , if someday for any reason i need to replace one of the panel , will i need to remove all the panel in sequence ? or i can just replace that panel separately ?

[@mattbrew11]

I own a solar company in the us with more than 65000 home systems installed. I can say with absolute certainty that the roof pitch utilized here is in no way ideal. For year round ideal production on a system, 50* of tilt or a 14/12 roof pitch would work best The other issue with this system is that you are losing convective cooling, which is the same reason a tesla roof tile is wildly inferior vs a high qualify PV module

[@JohnSmith-jk8mt]

I'd love to see the Tesla solar roof being installed in the UK

[@Electronzap]

Pretty nice.

[@AndreasDelleske]

I can show you a roof where a part of the modules (total 24 kW) is set up on a flat roof with correct ventilation, a part is fixed a little too close to a roof below, so less ventilation, same inclination. Same modules, same production batch. After 18 years, 38% of the panels mounted on the less ventilated are had errors that cost them 33% of their respective yearly production (A substring fails means 1/3 in gone) By not having a proper ventilation behind the modules, you not only lose up to 30% efficiency when hot, you reduce lifespan considerably. Also I dispute that it may possible to mount the module so that absolutely no water gets behind: We have considerable heat expansion so the modules must have a gap to compensate for that. The gap is where the water will come in but not a problem if you set the modules on top of a roof, not integrate them as you did. I am all for optical integration but there needs to be ventilation.

Really useful vid (as ever - thanks guys!), as I'm just about to press the button on a Viridian in-roof system to coincide with a re-roof.

Optimisers can't go in the loft - as there isn't one! Any comments from experience of this?

In ontario, code requires a combiner box with fusing/disconnects within 10ft or so of the array, accessible to the person on the roof.

Wasn't the roof long enough to fit two more panels? I would even have aimed for increasing the width by making the asymmetric shape even more extreme so at least there could have been fitted on 24 panels. Would the system allow to cover the entire roof with panels or is the presence of at least one row of tiles all around unevitable? I would never prefer in roof systems because of the lack of natural panel cooling effect without backside air circulation nor have too much confidence in the waterproofness for several decades.

[@leverloos]

this is 100% more expensive then a regular system on rails. Only thing that offsets the price and makes it on par with a regular system is if it's a new roof, and you wont need roof tiles where the panels are.

[@marekmarooo3398]

What about airflow and overheating panels?

[@albex8484]

The pitch of the roof is low, so during wind and rain, water will go in between the blue plastic. + there is no vertical wooden structure. The water will get stuck on the wooden horizontal lats and rot. Not a lot of water, but it will give issues in 10-20years. What is also already pointed out, is the panels cant cool down. Even in the UK this seems bad and i wonder if it has influence on the life span of the panel. The rest seems very neatly done and beautiful.

And the same for Installation? i think this is very interesting if you do an attic conversion on an old house and raise it by 1 or 1.5 meter to create some new living space. then you need a new roof as well, and make it similar asymmetric and put in three big windows in - everything well suited for the solar panels. however, in Austria it would need a different design, maybe steeper to be better suited for the winter sun and for letting the snow glide down and sacrifice some efficiency in the summer, where you have enough output anyway.

whats the work wear jeans name? looks comfyy.

Are you doing it to look fancy or to be functional? Solar panels perform better cold. There is a purpose to mounting them spaced off of the roof. Also makes replacement simple. How hard will it be to remove or replace panels?

The first thing I thought when I started watching was that will be something done by a plumber.

You guys would be outstanding if you could give us the name of the song at 7:07 ! Thanks for all those inspiring videos!

2:25 I am wondering if that will become a standard in roof design going forward. It should be a lesson to architecture I think.

[@ShortVersion1]

Interesting! I've seen a couple of these in EU, must be because underlayment has been getting better? In US, the asphalt roofs are standard and obviously this is for higher-end systems. Anyway, I'd imagine in the past you needed the redundancy for water tightness and now you don't? I know that the Tesla underlayment for solar roof is "more of a barrier than typical roof" according to our installers.

Nice

[@ram64man]

you forgot to mention that not all solar panels including the latest max outage are possible to be fitted to an in roof design, the kits only fit normally up to 410w pannels 72 cell

Would love to go for in-roof, but I doubt the cost to re-do our roof (24 years old) would be worth it.

What about Scottish roofs that are fully boarded with 150x19mm sarking?

Are the Artisan crew going to be attending the CEF live trade show this year?

Standing on top of a step ladder is bad enough, but when it is next to a ready built tower, just ludicrous! 12.50 into video.

[@Taylor201100]

one down side is if one panel fails how do you replace it easily if they are all interlocked

[@yordannedelchev4784]

Looks good, but maintenance wise this is the hardest it can be!

I’m not overly keen on viridian i feel like when it’s hot they can’t breath at all they must get a lot hotter than some of the other in roof kits
