Hyundai Shingled Solar Panels - 15% better than other solar panels? (S.P.A.T.-Test 🍺)

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.

Great testing - I like that you did it in various weather conditions. Nothing beats real-world results. Those Hyundai panels are impressive.

[@OffGridGarageAustralia]

Thank you, yeah, wanted to know how they perform under different conditions. More testing coming.

[@farside87]

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.

[@Matt-re8bt]

Bang-on, @Farside. It's about the density you can fit on your roof.

[@OffGridGarageAustralia]

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!

[@edmundzed9870]

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!

[@juanqg]

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.

[@OffGridGarageAustralia]

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.

[@catch22frubert]

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.

[@jlegen]

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…😇

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

[@OffGridGarageAustralia]

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.

[@bimmerboard]

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?

[@OffGridGarageAustralia]

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...

[@bimmerboard]

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.

[@OffGridGarageAustralia]

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

[@marknichols7861]

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!

[@SolAce-nw2hf]

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.

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...

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

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. ✌️👁️👀👁️👍

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.

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.

[@serraios1989]

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

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).

[@erwa8729]

Sehr aufschlussreich. Vielen Dank. Jetzt heißt es, bei Sonnenschein so viel laden wie nur geht. Eventuell ein neuer Victron 150/45. :)

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.

[@OffGridGarageAustralia]

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...

[@svegetax]

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.

[@ThanosSustainable]

They strips are parallel as initially thought. Voltage drops because the MPPT is stressing the cells, that’s how MPPT works.

[@dougydoolittle5255]

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?

[@OffGridGarageAustralia]

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/

[@leonhardtkristensen4093]

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.

[@OffGridGarageAustralia]

Yeah, I would do the same if I had the space, just keep adding solar strings until it is enough in winter.

[@lesthompson5907]

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 .

[@jasondevine6014]

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.

[@OffGridGarageAustralia]

I'll test again connected to my 48V battery.

[@margarita8442]

My theory is those mosfets are connected in parallel and are used my the mppt to adjust current in the power meter

[@highlander2330]

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?

[@tastiger91]

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.

[@OffGridGarageAustralia]

I don't know her, sorry. Get a quote fromm QSO as well to have a comparison.

[@3DLL.]

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.

[@OffGridGarageAustralia]

Thanks for sharing. Isn't Q-Cell a different brand 😁

[@Daraghfly]

Why don't solar charge controllers have some kind of over voltage protection?

[@diysolaradventures7894]

I'm trying to figure out what is it you're actually doing with the beer can ?

[@davidswihart4333]

following. have solar ever 455w panels now. need some more

[@OffGridGarageAustralia]

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.

[@pltspemula]

Singled sangat menarik. Bisa berumur panjang ya Tuan...

[@pteepan2708]

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

[@Adrian-foto]

Thank You for a great video :) What is that universal powerbank at around 15:40 ? I am looking for something like this now. Does anyone have expereience and recommendation? I see USB PD port and if LIFEPO is built in, would fit my purpose. Thanks for sharing

[@St1leth]

Its Bluetti EB150 portable Power Station

[@OffGridGarageAustralia]

I use this Bluetti Power Station every day as a generator replacement. I run a lot of tools directly from it and also charge batteries out in the field. Super versatile with 1.4kWh of storage and 1kW inverter. Here is the video about it: kzbin.info/www/bejne/b2jHZWWkrsuohc0

[@Clark-Mills]

Old video but I'd suggest that the blocking blanket isn't dark enough possibly?

[@OffGridGarageAustralia]

I also tried with 2 blankets...

[@davidreece1642]

No need for microinverters or optimisers for shading ( excluding panel monitoring)?

[@OffGridGarageAustralia]

I'm limited with what sort of micro inverters I can use in an off-grid installation and how many the MPII can handle.

[@Dutch_off_grid_homesteading]

Heya, I'm looking for the highes powered solar panels I can get I can only put so many panels on 1 roof

[@chuxxsss]

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?

[@OffGridGarageAustralia]

I think it's just in internal resistor which smoked here... I'll check.

[@chuxxsss]

@@OffGridGarageAustralia Do a small put down. Need any help I am an ex army communication technician with component level repair.

[@jetfu400]

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?

[@asabriggs6426]

28 panels at up to 400W means over 11kW of solar, so the existing MPPTs are insufficient. Are you planning on upgrading the Victron MPPTs, or will you be looking at trying out an all-in-one to pair up with PowerWall 2.1? Something like a Deye SUN-12K-SG01LP1-EU would be able to handle the panel power and be much simpler to wire up (although the battery charge configuration may be troublesome).

[@andybierlair]

I was going to ask the same question to Andy. If he stays within the Victron Ecosystem, I believe this would be the right time for the RS 450/100 MPPT

[@asabriggs6426]

@@andybierlair Ah yes, they look the business; an RS 450/200 with 4 strings of 7 panels might keep the wiring simpler and allow the MPPT to gather the most power in shaded areas.

[@OffGridGarageAustralia]

That was the plan from the beginning of designing the PowerWall. We left some space for additional MPPTs in the top left-hand corner of the wall. They will all be 150V MPPTs and one controller will drive on space of the roof (west, east, shed and carport). The RS controllers will not work for me due to the shading. It makes no sense to run high DC with long strings in my case.

[@james10739]

I mean without any load just resistors basically a heater 400w is a lot for something that size seemingly without a fan or anything

[@sebydocky5080]

What is the tester model working up to 800W ?

[@OffGridGarageAustralia]

On my website with more details. It also has a better display now with more information: off-grid-garage.com/measurement-tools-and-analisers/

[@JN-ou9ws]

Hi, Andy I was wondering how the battery is charged. Let me explain, My panels will not charge at full cap. With almost full batterys. In other words how do they charge on an low battery & how do they charge on a fuller.

[@OffGridGarageAustralia]

All depends on your setup, what gear you use and what settings your have set in your charge controllers.

[@ahmedal-mashhadi4202]

Know what the difference between UF and VG is ? Just lower variation / higher reliability ?

[@OffGridGarageAustralia]

There is a comparison on their website (scroll halfway down): www.hyundaisolar.com.au/
