Working outside in the winter isn't always the most pleasurable thing, so having a piece of work to be proud of at the end of the week always helps. Welcome back to part two of this renewable energy project just outside Cambridge. In part one, we ran through renewable energy that can be used to power an electric vehicle through excess solar. If you missed that particular video check the link below. In this episode, the Artisan squad go through the bulk installation of how we install a solar set up at Artisan Electrics. Make sure you keep an eye out for part 3 in a few weeks, where we'll also be adding the myenergi libbi battery storage.

@essexcountyelectricalltd Год назад

Couple of suggestions Jordan, you can buy mc4 bungs that you can insert on the optimisers instead of taping them, for your cable entries you should always avoid piercing the felt just slide them up to the nearest overlap which easy to find, also cable entries on tiles i always a small piece of flexi conduit to protect from abbraision on tiles. also lining up your panels its easier to start at the bottom fit your first then string line across the bottom to the other side measuring up from bottom of roof. just fit another length of rail the far end to wrap string around then all panels will be straight. Then your top ones will be easier to fit also taking the weight from bottom panel while you get a couple of mid clamps to use as spacers. remove once clamped. Thought i would share some of my experience with you as your new to solar.. Keep up the good work guys

If you guys need to avoid induction loops, try leap-frogging the optimizers. Saves some wire management as well.

@robinheijblom2929 Год назад

I'm so glad you address the induction loop problem, explain it and also show the solution. It's the #1 cause of ElectroMagnetic Interference caused by solar installations. So you're not only preventing the damage caused by the induction currents of lightning strikes but also prevent a lot of other problems most people don't even know they have. A lot of optimizers actually cause a lot of EMI and if you would have made an induction loop you basically create a medium wave jammer. By putting positive and negative wiring next to each other you minimize this effect although in my opinion they should be in a metal conduit which is properly bonded to the protective earth. Even though solar panels generate DC, the switching electronics in the main inverter and power optimizers make it from a high frequency perspective more or less a radio transmitter if not proper minimizing unwanted inductive and capacitive properties.

@mfr58 Год назад

Yes bird protection is a must. I learned the hard way, However aesthetics aside, I prefer mesh as it allows more air flow to keep the panels from getting so warm in the summer and losing performance.

@nickdierckxsens2621 Год назад

Yes, no airflow is approximately 10% less yield. Going to be an oven under the panels in the summer.

@artisanelectrics Год назад

They allow plenty of space for airflow still as there is a gap of aground 20mm above and below - big enough for plenty of air but small enough to block pigeons

@TheGalifrey Год назад

@@artisanelectrics 20mm is still a significant reduction in airflow compared to a mesh, on a hot day you need a lot of airflow to maintain performance.

Don't understand the need for a skirt. We have our whole roof pretty much covered with NO skirt, have plenty of wood pigeons and doves around but they don't go under our panels ... At least not in the five years we've lived here. If any wood pigeons managed to get under our panels they'd probably get stuck they are so fat! 🤣 A MUCH bigger issue is keeping pigeons away from tops of the panels as their crap takes ages to be washed off by even heavy rainfall.

My understanding is if power is direct current you don’t get the magnetic field you’d get from an AC 50Hz supply. If I’m wrong feel free to correct me 🥲 Great videos guys, very helpful

@spamhead Год назад

Yep, it’s the changing magnetic field that will induce eddy currents, although ripple on the DC will cause them, but hopefully very limited.

@JohnR31415 Год назад

DC shouldn’t cause eddy currents, that’s due to (rapidly) changing currents in the cables.

@sanderspeetjens Год назад

True it's due to a changing magnetic field induced by an alternating current

@nusermane1076 Год назад

22:56 Since Eddy currents are the result of a changing magnetic field, which in turn can be the result of a changing current in a wire, they are mostly a concern in AC systems. For DC it would mean that you would need to have rapidly changing sun-power, which isn’t a thing (except if you live close to a windmill or moving trees, I guess … but even then it’s not as fast as 50Hz mains frequency current-change happens to be). However: If the inverter communication to the optimizers happens via powerline, then yes, there might be Eddy currents, even if they are weak, but it might mess up the communication. So … it depends 😅 But you would definitely not get these constant Eddy currents as you would have in a high load AC system, I guess and also in your case you plan to pass the respective in/out for negative and positive conductor through separate brass rings, which means, that the in/out currents are the same and of the opposite orientation, whereby the magnetic fields cancel out each other :)

@patrickcannell2258 Год назад

Generally Eddie currents are not an issue with DC.

@randacnam7321 Год назад

Also not an issue as the metal bits the wire goes thru are not ferromagnetic. Induction heating problems come when groupings of AC wires are all the same phase and thus have the same magnetic field, which in turn magnetizes the metal bits *that completely surround each grouping of wires* alternately on each half cycle. The hysteresis losses (each alternate magnetization takes energy to reorient the magnetic domains in the steel or ductile iron that such bits are made of and this reorientation happens each half cycle) are what cause the heating problems.

I would measure if in summer they operate below 50°C is fine, over 70°C is alarming. I would prefer the same metal being perforated with 4mm holes for example.

I have a Solar Edge 6.6kw system. 22 SE panels with DC optimisers and a 5kw SE inverter. Total was a touch under $10Kaud before govt incentives. My cost was just over $7000aud.

It's these Pigeons that will go under your panels, nesting, breeding, dying... they're very territorial and will absolutely make a mess. Type you see in the City. We have Wood Pigeons around us, they'll sit on the roof, walk about... but never go under them. This knowledge passed on to me by an ornithologist saved me thousands. If you're unsure... walk about your area and see other neighbours panels. If theirs is clear.... so will yours.

@davidbeakhust9797 Год назад

Strictly it both is and isn't eddy currents. More important is "Is the bush or enclosure ferromagnetic" e.g. steel. NOT "is it metal" With AC, (and with a ferromagnetic bush or enclosure), you will get an alternating magnetic field - it is like putting a single turn choke inline! You should not get those fields with brass (nonmagnetic) bush. Because brass is nonmagnetic, there is no more magnetic field induced than in air or plastic, so in turn, no eddy currents. An alternating field in the steel would cause eddy currents within the steel (like the secondary of a transformer, but shorted out) and so heat it up (why transformer cores are laminated- it stops the internal eddy currents). With DC, there would be a field (and so secondary eddy currents) induced only for microseconds when you switch on or off an isolator, otherwise nothing with steady or slowly changing DC.

In addition, I did not see any grounding of the panels (including eloxyide piercing tabs). Does the UK have any laws about proper grounding?

@@Mr1Spring I think the warranty period on SolarEdge optimisers is 25 years. I believe I've heard that we do not have grounding laws and that that is unusual. I feel like there may be some reasoning for it, possibly lightning.

@danielfisher2954 Год назад

@@RichardABW That would be strange, during our MCS assessment, the assessor asked what reading i got between the inverter and rails. I always wire an earth loop, take a leg to the first rail, link between rails and then a leg back to the inverter. One leg connects directly to the inverter, the other is mounted suitably close so that a continuity test is easy. Im not sure on whether this is a requirement by MCS or a regulation or best practice or manufacturer installation instruction ???

How did you go off-grid though. Just installed 57 panel Solaredge system, with new inverters but the Home Backup kit isn’t available until Q3, so when power goes off, so do the inverters, regardless of how much is in the batteries?

What is the best way to make a car port with PV panels as the roof? Has anyone any info to share on the best method to prevent rain etc. It will saved me building a roof.

@wezharrison7220 Год назад

Where do you get the little labels that you slide onto the cables? Like on your data cables etc. Make it real nice and neat. Thanks

kool look to the panels with solar skirt ...come guys - Arstisan way you could have wiped finger prints off skirt :) lol

What was the point why you split each string to both sides of the roof?

@tomandjerry1941 Год назад

good and fast and not cheap but you drilled the holes in the bottum when it should of been in the top ?

@dribzy888 Год назад

Hey mate you could of just turned the panels upside down on one side to make the cable run shorter.

can you show use how you do the stringline thing to get the panels straight please

@675matty Год назад

about your question of eddy currents, quick google and found this may help in the future. Does DC cause eddy current? Image result for do eddy currents happen in dc Electromagnetic induction is the reason behind eddy current. It will only occur if there is change in magnetic flux. In ac , the current is ever changing but dc , current is constant. So no emf is induced in the metal piece thus no current.

@dejanresetar1639 Год назад

from what I understand isn't it prohibited by inverter manufacturers to mix panels of different orientations? like in this sense you created one string comprised of panels on 2 different orientations (east and west)

@percyprod6574 Год назад

That looks afantastic job, but no doubt very expensive. I can't help but wonder how many years of mains electricity you could have paid for with the same amount of money.

@matthewfenney5088 Год назад

Not sure on eddi currents but ac and dc should be kept separate

@Fuxy22 Год назад

Aren't solar panels really sensitive to temperature though? Less on an issue in the UK I guess but you would want a nice perforated grill if you ask me.

I don't think this setup is enough to be off grid. Would be good to see the numbers.

@euroovca25 Год назад

15:30 just one grape... the "V" connection should be made on the SPD itself rather than in the terminals... through my 10 years testing systems, this proved to be the best solution often the only one really working and protecting anything ! i know that the manufacturers often include schematic of connection and yes the SPD is parallel to the feed but that one is just not correct.

@protectiongeek Год назад

Out of interest, would you have installed the SPD in the loft, much closer to the solar panels and their mounting rails? Surely mounting the SPD in the garage is inviting trouble from overvoltages causing damage to the insulation of the DC cabling from the panels down to the first isolator, or to the isolator itself?

@euroovca25 Год назад

@@protectiongeek the rule to follow is to install the SPD as close to ground as possible, in reality it doesnt matter much as long as the ground connection is solid. this is because the internal resistivity of the hardware is higher than the straight to ground connection so in case of direct lightning hit, the cartridge blows and ground resistivity becomes almost zero so its the only way for the energy to travel to. when we test datacenters or tecelom systems, the SPD is at the mains which tends to be the first in line component, as far from what we want to protect as possible. i know what you want to say, but the cables used in solar applications are designed for 1000+volts so this is no problem, the overvoltage is then safely grounded before it hits the inverter which is good, either way works. one more thing i will say that the SPD is present to mainly save the inverter, which is the most expensive device and the grid side, if you get direct lightning hit to the panels, you can kiss them goodbye, the diodes burn in every case.then again if you get hit by lightning you have done something wrong

solar skirt looks nice but doesn't allow airflow under the panels. as the panels increase in temperature the efficiency falls off a cliff.

@eric4709 Год назад

Eddy currents : You will ONLY have eddy currents from a CHANGING magnetic field!! ( ie electromagnetic magnetic induction from a time varying magnetic field) Since you are working with DC - there is no changing magnetic field therefore there cannot be any induced (eddy) currents.
