- Today, we're testing the Hyundai Shingled Solar Panels HiE-S400UF. These utility-grade solar panels have a very high efficiency and claim to be very effective in low light conditions.
I've got a freshly calibrated S.P.A.T., so I'm keen to test these panels out before we mount 28 of them on the garage roof.
I'm doing the full rain, shade, shadow and sun test with the panels and compare them directly to two panels which I also have on my roof. Are the Hyundai Panels really that much better? We will find out with some comprehensive testing.

Thank you Andy for being such a GREAT educator! You bring so much value to everyone around the world with your channel. I so look forward to your updates. Keep it up brother! 😊
Thanks a lot Dan 🙏
The biggest advantages I see going with the Hyundai panels is mainly their size. You are going to get practically double the output for just a little more than half the space taken up on the roof by the other panels. As for current, you might have to reconfigure your current charge controllers, or get more, or even bigger ones. It will be exciting to watch this next project develop.
Bang-on, @Farside. It's about the density you can fit on your roof.
I have maxed out my roof with 3.6kWp at the moment. With the new panels, I can pack 4kWp in less space and still have the required safety area around the panels.
I will re-use the old panels for other installations we will do in the future. Nothing gets wasted!
@@Matt-re8bt am I the only one who sees that the Hyundai panels are bigger then the others? If they are 15 % bigger,
you don't save much space if they deliver 15% more energy.
@@edmundzed9870 but with the setup on the panel you can take advantage of shade. If you loose half of the panel it’s still putting out energy.
@@clarencewiles963 How is that important? Solar panels are an investment and it makes no sense to put them in the shade.
Efficiency on the other hand is very important, that and the price is what I am interested in more then anything else.
A return viewer today, just shows how sharing a wealth of knowledge openly on the Internet is the gift that keeps on giving!
Thanks a lot Trevor!
Great testing - I like that you did it in various weather conditions. Nothing beats real-world results. Those Hyundai panels are impressive.
Thank you, yeah, wanted to know how they perform under different conditions. More testing coming.
Interesting and informative test Andy, and once again you have demonstrated that there's nothing like real world testing to bring specs, marketing and science into reality. Thanks!
Thanks, Jack. Some of my viewers said they have the Hyundai panels and are pleased with their output. It will be very interesting to have them on the roof and compare the overall yield to the old panels.
@@OffGridGarageAustralia Indeed, I'm looking forward to the result, and if for nothing else, it's good to have an alternative source country.
Considering all the sun, your need for power, and the scientific minds you have in Australia, it would be good to see Australia become a world player in the solar market.
Got a good laugh at you cursing the clouds!
Thanks for sharing. I have been wondering about shingled panels, especially since your last video looking at them.
The last one we tested were just the crappy attempt from a company to sell overpriced panels with no grunt and power output. These ones seem to perform as they should. And 25 years of warranty is a word!
Great video Andy! The breakdown of power per area was extremely helpful for evaluating these panels as overall space available is an important variable for many people. I'm in the U.S. so I'm not sure if these are available here yet (and of course at what price including delivery), but you'll have to do another video where you include the watt per area per dollar, even if it's just in Aussie bucks. Then we'll get the ultimate ultimate comparison evaluation video, heh. Hope all is well and Prostata!
Thank you, yeah, doing more testing as we speak. I have now both panels connected to the large battery and keep testing. I haven't got a final price yet and it's a bit hard to know as I'm getting these incentives and it is all clear as mud how much they would cost i real life.
Hi Andy, thanks for testing, the Hyundai is offcourse less aged, but nonetheless the way they produce during partly shading is very nice and useful. Thanks for sharing and enjoy your spats
Thanks Edward. Yeah, new vs old but therefore the Canadian Sharp have 10% more output (400W vs. 435W).
Those Hyundai's seem really good 👍
Good to see a fellow Vegas Pro video editor 👍🍻
Looking forward to you next vid 🎉🥳 Cheers Andy 🍻🍻
Thank you. Yeah, still running the old version of Vegas which I bought on eBay 6 years ago for little money. Working great, does everything I need. And I know its features. Just haven't got time to look at other options and learn a new program.
Great review, Andy! Cheers 🍺
Hi Andy, nice video as always very interesting, probably it was already mentioned before, all the panes are parallel to each other, the difference you see in voltage / amps is actually the MPPT conversion (Good test for the victron very nice transformation) in order to measure the panels you have to either recover your tester or use a known value resistor and calculate the voltage across to estimate the power.
I think the two parallel MPPTS of the same model showed all the numbers to compare the panels. Unfortunately, I don't have a half-cut 400W panel to make it fair to compare.
You too Andy, stay charged stay safe and thanks for your informative videos!
Still my favorite CZcams channel!
Awhhhh, thanks so much!
Thanks Andy. Great stuff as always 👊🏾
Thanks Lennie!
Oh, I can think of one more test you could start performing, to compare solar panels. I’d like to know how the different panels respond to various incident angles of the light. For example, we all know that panels perform best when they’re facing the light head on, but do some panels perform better at other angles? This could be particularly important for anyone using fixed mounts that can’t change angles. This is kind of analogous to viewing angles for LCD monitors.
OK, that's a great suggestion. You can already see the difference in the Victron VRM when looking at the Hyundai Shingled vs the Pool Fence solar. As the sun moves across during the day, they get different angles of light and have different power outputs.
vrm.victronenergy.com/installation/100328/share/d0ebad4e
Andy since the Mppt is always searching for the ideal voltage to get the max power it doesn't say a lot the numbers it delivers to know if they're in parallel, in series or something in between, to have a clear picture you should consider open circuit voltage and short-circuit current while shading different parts of the solar panel
Agree
That's why I turned off the charger in the controller, so it shows the Voc, the Vmp 😉
Can't Wait to see the new solar array, Andy! Congratulations! Those Hyundai panels were very impressive in almost all of your tests . You are going to have more power than you know what to do with. You will have to get more 304Ah EVE cells and you can become your own power substation and the electric company will be paying you every month!
A great video with awesome comparisons! Keep it up Andy
I'm a follower of your videos and also an off-grid solar user since 17-Jul-2022.
Below is our setup:
- Growatt SPF 5000 ES inverter
- 4 x 460W solar panels (JA Solar JAM72S20-460/MR/1000V; 144-cell half cut mono-crystaline PERC)
- 15 x 105Ah 3.2V LiFePO4 cells with BMS (TDT-8480-20S)
Thanks Amil. Wow, look at you, what a great setup, nice!
Thanks for these really interesting practical testings! One idea for some more comparable shadow-yield-tests: testing in full sun light with panels covered with some sort of mesh or fabric to „apply“ the exact same amount of shadow should give much more trusty numbers than just dealing with some differently sized tree-shadows…😇
More testing in place at the moment. I have now two of them in series and connected to the big battery. It's also visible in the VRM with all data and stats. vrm.victronenergy.com/installation/100328/share/d0ebad4e
Brilliant review, thank you!
If you have a metal roof that's a bit reflective, I would consider bifacial panels... I think they would work great, but that's not based on experience but based on reading about the technology.
Uiiiii..... neue Module😍 für die Off-Grid Garage
A bit of trivia on the name Hyundai- They had a run of TV ads in the USA and Canada when they were introducing the automotive brand - the message of this campaign was “Hyundai rhymes with Sunday”.
Nice panels!
Will you be changing any of the panel angles or these will be going straight onto existing rails? Keen to find out. Another great project Andy. Thanks
They will be following the rails and existing roof angle. Only on the flat carport, we will have a 10° angle on the panels so the water and dirt can run off.
Nice test ... sheeet fried the tester. Thank you Andy
It survived somehow but has this funny smell now. I assume they are using a resistor to bleed off the energy when measuring and it got a bit too warm. I'll open it up at some stage and see if I can replace it.
I use those panels since last spring. Great product. I have 410w
Great, do you have the UF or VG panels?
@@OffGridGarageAustralia VG.
Last week I succeeded to connect JK BMS and Cerbo GX using Louis Van Der Walt serial driver. It works on Cerbo GX. And JK BMS SOC is used now by Victron
Great video, Andy. From the looks of the way the panels responded to shading, it seems that you could gain quite a bit of production by properly orientating the panels. In your test example, if the shading were to move from side to side across the panel, rather than from top to bottom, production could be maximized, versus having the shading move from top to bottom. What do you think?
That is true bit very hard to achieve. Due to the limited space on the roof, there is only one orientation for the panels possible. And if I could 'waste' more space for having them oriented differently, I would probably rather install more panels on this space to compensate for any loss in shading conditions.
But more testing is on the way...
Awsome testing, and results. Another interesting test would be the 2 Hyundai's separate,1 in full sun at temperature and the other being cooled by a mist or drizzle of water.
Or two Hyundai panels - one in perfect orientation and elevation and one on a second controller with the same orientation and elevation of your shed roof. Such a test could also be compared against your sharp combo to determine if one technology is affected more by less than optimum orientation.
Doing more testing as we speak...
So, many thanks for testing of your solar panel tester WS400A 😁I've been just about to buy such a device, but now... I'll look for annother company, which fuses the limits to avoid smoke...
When I have to carry/move my large panels I put on those grippy work gloves, the ones with rubber palms. They make carrying hot and bulky panels SO much easier.
Great video👍
Just got to the end of the video.........28!! 😲😲😲😲 Soooo looking forward to your next video now! Wont that many be enough to power Australia tho?! 😂😂
Plus I'm getting 6x540W half-cut Phono panels on the Tesla carport on a 10° angle.
Na, this won't be enough, there will be more. We will re-use all the panels from the garage for other projects 💪
Très bon test ! je devrais essayer aussi ces panneaux HYUNDAI cela me semble une bonne expérience de production pour mon 4éme strings. Merci ANDY
Cool video again 👍❤️
Thank you 🤗
Thanks Andy, 400 x 28 is a lot of killer wasps 🤔 Be great in the winter 👍
Plus 6x540W Phone half cut panels for the car port. Yeah, this is all for winter usage basically. Summer is never a problem...
Agree with Farside here. W/area is significantly better with the Hyundai. I will look to get some of these here in the UK!
You're going to have 11200kw in panels????? W0W! 👍👍 two thumbs up.
Thanks for the video, there is nothing better than real tests to check the behavior of the panel
I have a 410W Hyundai VG panel that I wanted to install on my 12V camper. Unfortunately, after reading a lot, I think that it is not the most recommended due to the amount of shadows to the left and right that the roof rack of my van can generate. (Since the panel I have to place it vertically and not horizontally as in your tests).
I guess I have time to do tests, but I don't know if 2 panels of 200W in series will be a better option...
Great Video, We are looking at the Hyundai 390-uf for our system in Tasmania. Lots of cloudy days, rain and some shading. It's hard to find good information on these subjects. Most is related to mainland conditions. I was very interested in your results especially in those conditions.
These panels work great in all conditions. I'm really impressed with their performance having them for 3 months now. An I constantly monitor them through the app😉
the 390-UF are the older panels though, the new ones are 415-UF, same size but 415W output.
I have made a few videos just after the installation in different conditions showing the performance and they don't disappoint.
@@OffGridGarageAustralia Hyundia need to change their website, I can only find the UF series in 385, 390, 395 and 400W
I have those panels in the UK. Have made a car port and use them as the roofing materials. Silicon the edge to limit the drips! LOL. Keeps the rain off my car and generates power when sun is out. Matched them to a solar edge 2.2kw inverter.
Nice, thanks for sharing. So, your panels are the roof? That's a great idea for a car port.
Nice test. I wanted to see if these Hyundai panels look as nice as they say, and how they perform in various conditions. You could not have done better.
It is impressive to see how well the shingled panel handles partial shade.
And even more so considering the much larger surface area of the combined competition.
Seems to me that shingled is the way to go if trees are a factor.
In my situation i have some ventilation and heating chimneys that cast a long shadow early in the morning. So in portrait, it should be able to handle that.
On a very cloudy day any panel will do. Not much to lose anyway and the scattered light makes any optimizer or bypass diode quite useless.
Hi Andy from less sunny Melbourne.
I have plugged in the specs to the Victron calculator Excel sheet and you will not be able to run 3 in series (on your 150/35).
But if you had the VG series, then you could, because they are slightly lower Voc, and higher Isc.
"Max pv voltage @ min temp." UF=158.5v VG=148.6v
These panels are close in dimensions to your existing, so I assume you'd still mount 3 per rail.
I'm perplexed as to the real-world difference between the UF and VG range - apart from a small gain in efficiency.
Given the Victron SCC range has a 150Voc, then the VG would be better.
Thanks for your great work.
Rob.
Thanks Rob, that's what I said in the video 😉 The VGs are not available any more... and I would not be able to have three in series either due to the roofspace.
Impressive production to size ratio!
Yes, they are a lot better in output for the same area. Technology is moving fast.
@@OffGridGarageAustralia Exciting times!
Thanks Andy- very interesting!
Thanks Dave. Could be an upgrade for your RV in the future...
@@OffGridGarageAustralia I’ve got almost exactly 1kW on the van, with a wide mix of various panels which have been added over time - the oldest being 3 Japanese 120w panels I bought in about 2001. They were about $10 a watt, ($1200 each panel) AND they were “bigger” dollars of course.
@@OffGridGarageAustralia I’d LOVE to fit new panels on my caravan Andy - they’re mostly old (and inefficient) by today’s standards.
Interesting - my original Japanese panels from a little over 20 years ago were AUD$1200 each, for 120w panels, ie $10 per watt, and they were much bigger dollars too!
However it would still be a big expense and also probably a bigger factor: I’m getting too old for such jobs.
Good stuff Andy - the reason they are not warrantied outside Aus and Europe is they are not available outside those locations-
Interesting...
Get your self a hand truck with air tires, and a angle iron on the bottom to protect the panel. So you can roll them around. The new system are getting bigger and heavier. Keep doing your good updates, thanks.
Great panels, amazing for the marine world as their footprint is small and they suffer shading from the mast very well. Bi- facials used to be the go too for marine, but these have taken over. Glad you got some for yourself Andy, you won't be disappointed.
And they are especially protected from salt water, it says in the specs.
@@OffGridGarageAustralia salt water protection is an important feature for marine applications for sure. They use the "adhesive conductor" tech that makes them resistant to damage from expansion and contraction from temperature fluctuations, and also the flexing that all boats experience while out at sea.
@@boatelectricaldiy They are indeed quite flexible, so ideal for such applications where this is needed.
Seriously Andy, for that size I would say they are “significantly” better than the other two. Look at the size difference. It’s like half the size for the same productions.
But anyways thank you for the video always awesome quality
Yes, they are, I talked about this in the video and compared the size and output.
Hey Andy @offgridgarage
Have you been looking at the N type panels coming into the market?
I’m looking at the Jinko Neo N type
New subscriber here.. i personally dont go up 200 watts too heavy to install on my rooftop
Nice test!
Man, panels are 2x as expensive as last year... That is if you hire a company too do it a to z. Insane.
Thinking about ordering myself SunPower P6 400W panels with IQ7+ inverters(11 to 13). Then hire a company to install the panels and do in-house electronics myself. Any thoughts?
(This is for my main residence. The off-grid is Victron managed)
Yeah, all the electric is not DIY stuff unfortunately. The insurance does not like that. I'm glad I found an electrician in this area who knows what to do and can help me out here...
I like those Hyundai panels, I might buy a couple
I've got them on the roof for 6 months now and they are awesome. Very good in cloudy conditions.
Hey great stuff, thx a lot. One more general question: could u do a test placing solar panels facing the "opposit" side of the incoming solar radiation? This would be the case if one chooses to put solar panels on a roof which faces north (northern hemisphere) trying to catch especially the diffuse part of the solar radiation... i would be excited to see the results
Sure, can do. I'll do a comparison with different directions and angles.
@@OffGridGarageAustraliawow cool. thx a lot 😁
Regardless of whether or not cell strings are parallel or series we must calculate shading of each cell as a load - a resistance load which in deed can be a variable resistance load. Generally, shading introduces high resistance in the circuit where electrical energy transforms to light heat and sound. ✌️👁️👀👁️👍
If you put a wooden pole or similar under the back of the panel to lift it to the right angle, it can crack the silicon cell as there is no glass on the back, just a thin plastic film. always support it by the frame.
I do like those new panels they are cranking out the watts.
They actually do. I'm really impressed so far.
Thank you for the great video Andy! Im just about to buy the Hyundai 490Wp panels with Enphase iq7a, but these micros are rated at max 366W power output. What inverter system would you recommend to get the most out of the panels woth a bit of shading? Even after 25years the hyundai panels should have ~410Wp, rated way above the 366W max power output of the micros so it feels like a waste of money to buy such high rated panels.
Your dc/ac is 1.338, certainly within the acceptable standards. You will see some clipping. It depends on the latitude of your location, orientation and inclination of the panels, ambient temperature, solar irradiance and shading on the panels. Enphase has published some papers that you can find online and basically they say that energy loss from clipping over the life span of the system is minimal. You can use the PvWatts model to calculate output with various dc/ac ratios. In the Enphase forum a few discussions are going on about clipping without reaching any conclusions. I have Hyundai and Enphase and I see some clipping but it’s extremely difficult to calculate how much exactly. Overall the system works well. Enphase claims that the smaller inverters produce more when they are not clipping and there is some evidence that this is correct at least to some extend. I would go ahead with the system.
I suspect you have multi oriented panels and that’s why you go with Enphase. The other option is Solaredge and probably you will have a bit more yield, but they are not as reliable as Enphase
Hi Andy Any thoughts on how the Hyundai Shingle panel would go on an RV application? Are the connections likely to be a weak point with vibration?
Based on solar serious cells along the length side or along the width side of the solar panel, the solar panel vertical or horizontal installation is matter/important during the early morning and at the end of the day when the sun gradually change its shine to the solar panel or when the shades appear/gone.
That was very interesting thank you have a great week. M
Thanks, Michael.
Impressive!!!
Thanks Joe. I need more solar...
WOW! 11,200 WATTS. Good on ya.
Plus 6x540W Phone half cut panels on the Tesla car port. 14.4kWp all in total.
the 800 W panel tester is way better. Testet it already with 550W panels in sunny germany back in summer. No smoke, no overheating, no fear. Works.
Vielen vielen Dank für den wirklich ausführlichen Test.
Bestätigt meine Vermutung dass die ganzen Marketingaussagen "hervorragendes Schwachlichtverhalten" etc. genau das sind: Marketingblabla. Tests dazu waren bisher aber praktisch nicht zu finden....bis jetzt. Natürlich sollte man nicht verallgemeinern, dein Test gibt aber einen sehr guten Hinweis dass man diese Aussagen mit Vorsicht genießen sollte.
Yes, seems, they are not better in low light conditions than other panels. With the shade of the trees though they seem to have an advantage due to their structure and how they are connected internally.
Mal eine ganz andere Frage: wie sieht es eigentlich aus mit dem giftigen Australien Getier in deiner Garage, zb Trichternetz oder Redback Spinnen, oder gibt es bei dir keine?
Very nice panels
They strips are parallel as initially thought. Voltage drops because the MPPT is stressing the cells, that’s how MPPT works.
Without looking at other comments, per pane looks to be a standard voltage rate of 14vV/2.85A @ 3% tolerance. So 14x10=140 / 140x2.85=399w +/- 11.97w@3% .
14v @ 2.8-3A with 3-5% tolerance is common in the electrical 12v charging/power world of DC electronics.
Good show. And yes. You need a new tester. No need to accidently short the panel after the tester shorts. Sad part is the same tester at higher voltage likely has nothing more than the regulators with heatsinks on them.
All very nice, so the Hyundai panel has an equivalent or even higher performance than your „Canadian Sharp“ Combo. But what you have not taken into account is that it takes up much less space! If you look at the output/squaremeter ratio, the shingled panels by far excel the Canadian/Sharp combo. The new panels should nearly double the output on your roof (or help you reach the same output with less space - if you have to observe the legally required distances to the edges etc). So perfectly understandable that you ordered the panels, Andi!
Thanks Philip. I have considered the size and compared the power output to the other panels in the video. You may not have watched that far 😁
@@OffGridGarageAustralia Yes, I had entered the comment before you came to that conclusion in the end by yourself! 😀
Sehr aufschlussreich. Vielen Dank.
Jetzt heißt es, bei Sonnenschein so viel laden wie nur geht. Eventuell ein neuer Victron 150/45. :)
Hi.
Are you running an actual load or you deployed the 'virtual load output' to simulate load on the panel? My MPPT controller does not show me more than 2 digits watts whenever I connect a panel without a load on it.
Time for the Elejoy EY800W. What's the difference between those UF panels and the VG ones?
Yeah, ordered one right after the 'incident' 😁
Here are the specs of both the VG and UF panels (it's halfway down on their side): www.hyundaisolar.com.au/
what wild happen if you was to cool the panel whit liquid nitrogen whit pipes to keep the panel ? would it increace power out put .
Where to buy Hyundai Shingled Solar Panels S400UF from? Do you have price details Andy? I live in Melbourne. Thanks
I have noticed that power optimisers on ebay seem pretty cheap. They put MPPT at the solar panel. Not sure if have to run all panels with optimizers on or if can just do the ones getting more shade in parts of the day. Also interested in trying out enphase grid tie inverters on panels but think need the whole setup and they dont support offgrid use though seen some using it as long as your loads stay on and use more than the grid tie will produce to not impact the off grid 'grid' production.
They usually clash with the MPPT of your system as you now have two MPPTs working on the same panels. You can kill your MPPT with that sort of setup.
I have some micro inverters here which I will test at some stage for another installation on the property...
I'm trying to figure out what is it you're actually doing with the beer can ?
Andy, bringing up again, I have this same issue with 5x49.3volts and my Growatt handles 250V. I want to explore building a voltage limiter to prevent the series from exceeding the Inverter's capacity - what do you think?
Someone here just said to tape off an area of one of the panels for 6 months until the first degradation took place and remove it afterwards again. A bit of a rough method...
Is it getting cold at your place and also have a look at the specs of your panels if they also have any tolerances like the Hyundais have (+-3% Voc).
@@OffGridGarageAustralia not very elegant, nor effective
@@OffGridGarageAustralia open circuit is +/- 2%
Do you know the difference between the 400UF and the 400VG?
The UF is a bit shorter (1646mm) and classed as M3 and
The VG is a bit longer (1719mm)
and classed as M6.
Slight differences in voltages and current but what the main difference?
The main difference is the voltage. Two of the VG in series will just be enough to charge a 48V battery but with a bit of shading, they may stop charging. The UF with higher voltage will be much better for my setup.
You can see and compare both on the Hyundai Solar website about halfway down: www.hyundaisolar.com.au/
Hi Andy, I enquired to Eve energy Co from your website and was messaged by Quaine Xiang, is she part of the team? 16 280ah cells were $3400aud-ish.
I don't know her, sorry. Get a quote fromm QSO as well to have a comparison.
Do the shingled panels have bypass diodes built into the back of the panels? Some panels have a diode box that not accessible or sealed.
My theory is those mosfets are connected in parallel and are used my the mppt to adjust current in the power meter
i thought you ordered 28 hyundai panels. that's more than 11kw of power. you are putting 4kw on the roof? where are you putting the rest?
my mppt victron does this too sometimes the mppt will find what ever is most efficient and has the highest power and sometimes it drops my 40v array down to 15-16v this only happens on partial shading
Singled sangat menarik. Bisa berumur panjang ya Tuan...
following. have solar ever 455w panels now. need some more
You always want more. More batteries, more solar. That's how I roll atm. As long as I have areas to install more solar, I'll go for it.
Why don't solar charge controllers have some kind of over voltage protection?
i have these panels 420watt each when they are half shaded they still work i think there called q cells i might be wrong lol but been working great for over a year now in the summer they were producing me 6kw a day.
Thanks for sharing. Isn't Q-Cell a different brand 😁
Yeh I think you might be right 5 in parrellel 2 in series. Your results would have been very different with a 24v battery as 1 single set of strings would not have been enough voltage.
I'll test again connected to my 48V battery.
What’s the next solar charge controller;)?
They are more impressive than the voltx panels, they look attractive too.
Oh, yeah, far better. They are working really well, I love them.
Old video but I'd suggest that the blocking blanket isn't dark enough possibly?
I also tried with 2 blankets...
I haven't seen those specific Hyundai panels in the United States that's probably why they didn't offer warranty for us over here..
I will go for cost per watt at my farm at least where space is not a problem. I take the cheapest I can find and put it up. At home it may be different as space is more valuable but as I have what I am allowed to at home (and then some) it is not relevant right now. Thanks for your testing anyway. It was interesting.
Yeah, I would do the same if I had the space, just keep adding solar strings until it is enough in winter.
Each lane has 36 cells in series so it takes two 'lanes' in series to create the full 72 series cells yielding 72 x 0.64v = 46.1 v Voc or 72 x 0.53v = 39.2 v Vmp. So likely two adjacent lanes make the series cells for one of five parallel strings. Each lane pair produces about 2 amps. Think of it like putting five 72 cells 2 amp panels in parallel.
All PV cells have some shunt leakage current so shaded lanes leakage with drag down the unshaded pairs current somewhat.
So, every two lanes in series, you reckon...
I realized these are PERC cells so their Vmp and Voc per cell is a little greater that normal cells. PERC cells have back side layer reflective, so it reflects light that penetrates through wafer back into junction, improving efficiency of cell a little bit.
So there are five row pairs, with each row pair having 72 series connected cells (cut cells). Each of five substrings are wired in parallel. Each of the five parallel pairs produces close to 2 amps Isc or 1.9 amps Imp. There is likely only one bypass diode across output terminals of panel. This is acceptable because each substring on can produce a maximum of about 2 amps.
Cool there is good panel. I want to buy it. How much your panel and what company buy it
It's best to google this and see who locally in your area sells them.
do you have a link where to buy these panels in OZ?
I have only found one place, Hyundai - VG Series - 400W Solar Panel
$395.24 oz
No need for microinverters or optimisers for shading ( excluding panel monitoring)?
I'm limited with what sort of micro inverters I can use in an off-grid installation and how many the MPII can handle.
My Solar panel came back from E-2. Time to upgrade the MosFets in the unit to high specs. The Canada Sharp is 100 dollars how much is the hyundai?
I think it's just in internal resistor which smoked here... I'll check.
@@OffGridGarageAustralia Do a small put down. Need any help I am an ex army communication technician with component level repair.
Heya, I'm looking for the highes powered solar panels I can get I can only put so many panels on 1 roof
Know what the difference between UF and VG is ? Just lower variation / higher reliability ?
There is a comparison on their website (scroll halfway down): www.hyundaisolar.com.au/
Mmm I got 400w Vertex S for one year now, can't see what those Hyundai got special.
