My feeling is that these and similar systems are premium offerings that are basically upselling solar systems to increase the margins of the installer. I don't think the majority of people will see enough benefit to warrant the extra cost. Solar panels are much better at dealing with shade and low light than they used to be owing to having half cut cells and three bypass diodes meaning the panel still produces power in partial shade (as it is divided into sections). I'd rather have a well installed system without all the extra inverters on the roof. I would imagine that a solar panel is more durable and reliable than an inverter so you are adding multiple extra points of failure (panels + inverters vs just panels). Probably the most important source of failure is water ingress in connectors so having fewer of them on the roof has to be a better option and with carefull installation (drip loops and sheilding them from rain), you can minimise the chance of failure.

[@chrisdixon5241]

The thing that wasn't clear to me from the video is, now the output from the solar install is AC rather than DC, so it will have to be converted back to DC again somewhere if I want a battery storage solution. Does that mean an additional box to somewhere to manage the batteries and power conversion? What are the overall losses like in this double conversion vs a "standard PV install"? How much additional power will be needed to run the box doing the power conversion? What powers the micro-inverters? If the electricity grid goes offline, do the panels turn into expensive roof tiles and the house loses power, or can they still generate and run the house?

[@AttilaZoltano]

"I would imagine that a solar panel is more durable and reliable than an inverter so you are adding multiple extra points of failure (panels + inverters vs just panels)." They give you a 25-year warranty on these panels, including the micro inverters and cables, compared to the typical 10-year warranty on larger inverters. In my view, this system is much better.

[@Giavel84]

@@chrisdixon5241 panels with micro-inverters are not advisable if you plan to have a battery storage solution. It depends on the country you live in. In the UK, given that there's not much sunlight, having a battery storage unit might not make sense, therefore panels with micro-inverters are a good option (micro inverters have a warranty of 25years while normal inverters don't go over 10-15years). If you live somewhere with plenty of sunshine, you could get panels with power optimizers on them (so you can still see what they are doing individually), a battery and one inverter. And if the electricity grid goes offline your panels will not generate power, no matter what system you install.

[@kadmow]

@@chrisdixon5241 ... However If you want a DC battery ""later on", you need a hybrid inverter up front (or a changeover cost will occur). If you put in an AC grid coupled inverter up front and want a battery later, the cheapest route is an AC coupled battery with its own secondary inverter supplying a "backed up circuit" - or with automatic switching (ATS) of a selected circuit over to the battery when the power goes out or the sun stops shining (choose your own poison) - NB. it also needs to switch back to the grid under normal conditions when the battery is depleted - preferably while the battery is above 20% - voltage sag and other negatives occur when Lithium batteries are depleted further under high power conditions.

[@alokkadam4416]

The best part of this is , the MicroInverter costs nearly as much as the solar panel itself if not a little more down our side..... so If you use microinverters you just end up more than doubling your cost. Another crazy thing is , with 20 Panels you use 20 microinverters so now you have 20 panels that can fail plus 20 inverters that can fail, which will need to be replaced individually everytime and you need to get onto that roof to get it done.... but with the string inverter you have 20 panels as points of failure and just one additional inverter as a point of failure and the moment that fails it can be immediately replaced at the cost of just 2 microinverters , the shading and partial covering is not that much of an issue these days with monoperc halfcut topcon n-type bifacials and by the way bifacial panels are never stuck onto a roof.... you have to have a minimum mounting height equivalent to the length of the panel to make atleast most of what the bifacial has to offer , and those thin transparent lines between the cells.... won't allow enough sunlight through to even light up a half watt bulb with all those panels connected.

[@vevenaneathna]

a lot of systems are all racked togeather and almost every panel needs to come up to fix one failed micro inverter. inverters should be placed out of direct sunlight and used as little as possible. string inverters can be placed lower down in the shade and with easy access to fix without the need for renting a bunch of expensive scaffolding. turns a 1 day 1 man job into a 3 day 3 man job just to fix one failed component, usually not worth it until several start going bad. solar installers love microinverters because they can slap the stuff togeather and throw it on the roof and move on to the next install as soon as possible. if they were worried about repair they would all go with string inverters. rather have the heat producing component of a system on a different part of the house with no need for a ladder... and can also go inverter-less with dc systems which are gaining in popularity. a small mini split 120/240v uses around 180w to run all day, a small 24v dc mini split uses more like 65watts. similar with fridges. i think more and more houses are going to start being wired for DC coz the AC losses make no sense. solar panel makes dc, step it up to ac in the micro inverter, goes to a charge controller which steps it back down to DC, DC is used to charge batteries, then it comes out and goes into another DC-AC inverter into the wires of the house, into an AC to DC power adaptor into the device you use like a tv or computer. so much waste each step. just go dc to dc the entire time, avoid the 30-40% loss.

If a micro inverter can start producing at 20v, not 150v like my system, I am all ears; it can be hard to get shorter strings going otherwise. Agree that microinverters mitigate part shade of panels, but as the product shows, they can also maximise productivity periods (as was very well explained by the presenter, gg). Would add that well designed cheaper dc systems can also do a good enough job on cloudy days, for those on a tighter budget.

[@FreekHoekstra]

This is exactly right, micro, inverters, help optimize when there’s different voltages coming out of the different panels. With a single inverter, it’s a kind of lowest common denominator output, so the worst outputting panel limits the other panels. This can happen if one panel is shaded, but the others and Sun like you said, but it can be for other reasons one panel might just be worse than the other ones. Regardless, it has to little to do with overcast days…

[@TheRealKuif]

I keep hearing this marketing-speak about startup voltage. It's not a important as they make it out to be. An inverter may startup earlier in low-light conditions, but that's when energy available is less anyway. So you might get 50% earlier startup, at a time where 2% of the day's energy is available. So I wouldn't get too hung up on it.

I've always wondered if, in the future, homes should just have an AC and a DC line. Because I bought one of those sockets that also have USB ports on them. And it just struck me as odd to, you know, capture DC with a solar panel, store it DC in a battery, convert it to AC with an inverter, it travels a few meters, then it's converted back to DC again to go into, say, a DC battery (like a phone or laptop). There's, like, some needless conversions there. And I was thinking, instead, a battery-equipped house could run an AC line to traditional 3-pin sockets, but then also there's a DC line that runs to a bunch of USB C ports around the house. Low-power devices can skip the AC conversion. Just plug them into the USB port with a direct DC connection to the battery. Efficiency!

[@fintrollpgr]

It's going to be fun frying your 5V DC USB devices with the 500V+ from solar... You will need all kind of voltage conversion on that DC line anyway, even if it is more efficient there will still be losses.

Microinverters are such a scam... "If one fails, all will fail". Well, perhaps he haven't learned yet about bypass diodes. 200V for string inverter to start vs 20V for single panel? Well, guess what - string of 10 panels, each generating 20V gets you to 200V already. And most string inverters can start with 120-150V, btw. Put on top the fact that the microinverter operates directly at the hot solar panel on the roof, in rain, freezing temperatures, hot temperatures, ... while the string inverter is somewhere in a garage or at least shielded space... And many people found out about the problems with warranty - you will get replacement of the microinverter, sure. But is it still compatible with the old ones you have? Or do you have to suddenly replace all of them due to one faulty? And if your installer went out of business and you don't have the same code to connect them all together? And then add the price and we are done.

Yeah. Quite a lot of bollocks in this piece.

[@MustangGlos]

Micro inverters or optimisers are a great solution to a shading problem…if there’s no shading, don’t fit them. One string inverter is far less likely to fail compared to 14? Micros or optimisers operating in harsh weather conditions. As for efficiency, they are worse, by approx 2%. That super 20 year warranty is great but it won’t pay for the scaffolding which could 10x the cost of the micro! The voltage on panels in series is multiplied by the number of panels, so there’s no issue with start up. Trying to replace a panel with a built in micro in a few years could be a real head ache. Don’t pay extra for a problem you may not have. No substantial shading = No to micros or optimisers 100%.

[@ianbeck5897]

I've had micro inverters on a previous house (installed by a company that we engaged) and we have a dual string inverter on our current house. The first thing that happened was that the micro inverter company went bust and the 20 year warranty went with it. Luckily, in the ten years or so of ownership none of the inverters died and the system performed well. We had some shading and the MI were ideal for that scenario. In our current house the string inverter died last year and we had it replaced at a cost of about £600. The new inverter has performed very well so far and where I thought that the poor performance was due to trees causing shade previously, no such issues with the new inverter. This is on a ten year old system. The panels are working fine. If I was starting out again with a fresh install, and assuming that there is no major shading, I'd go with a string inverter. Why? It costs less in hardware and, if unlucky enough to have an inverter die, it's a one hour job to replace it and there is no need for scaffolding or engineers trying to balance on roof ladders to change a panel cheaply. Do micro inverters fail? Well, we were lucky in that none did. A neighbour who also had the same brand of inverter has seen half of his die gradually over the past twelve years. Yes, they may be under warranty, but the warranty "may" only cover the hardware costs, the installer being responsible for the cost of installation and, if he has closed the company down the cost for the scaffolding and the labour may fall upon the customer - if he can find somebody willing to change the hardware.

You'd need to convert back from AC to DC again to charge the batteries, which would result in more losses and basically negate the benefits of the microinverters. Any AC coupled battery is still doing an AC to DC conversion, as a battery doesn't charge with AC current. So the most efficient solution is likely to be DC panels going straight into DC batteries, as there's only one conversion, that's when discharging the batteries.

In the end the inverter has an output of 230/400 V so if you feed it with 250 - 900 V DC it's way more efficient than using 20 V DC and converting that to 230V Then you have electrics on your roof minus 10° in winter and plus 60° in sommer because it's directly mounted on the back on the Panel. Which is also really not a great idea because of heat. And that should last for 25 years I doubt it. Which brings us to the guarantee very nice, but it's just the micro inverter which is about 100£ or even less but how much is the installer coming by and replacing the thing?

The best ROI is on a small 1000-watt system with a microinverter that can handle 2 panels that are grid-tied. Especially when you can install yourself on a shed, 400 quid should do. Energy generated should be consumed, so working from home helps as running dishwashers, and dryers and watching machines during the day. Payback time is just over a year.

[@luc_libv_verhaegen]

The enphase system does AC all the way it seems. This means that for batteries to work, they have to be AC coupled. So for any electrons to go into the batteries, the AC current has to be transformed to the DC that the battery accepts, and then to use battery power, you have to invert it back to AC. This is shown in the data for one of their IQ batteries (the 3.3kWh one): the battery itself claims to have a 96% roundtrip efficiency, but the AC inverter that has to be included has a 89% roundtrip efficiency. For an equivalent DC system, you only do the AC conversion once, so logically and simplistically we can take the efficiency of the micro-inverter(s) and the efficiency of the battery itself as the efficiency of the whole DC system. Then we are still left with the 89% of the extra 2 inversions that the Enphase battery system has to do. As soon as you add storage to this system, all supposed advantages of the enphase system go up in smoke... Well, heat actually...

I like the idea of generating power on the back of the panel … although I’d be surprised (and am a bit dubious) that the rear of the panel can generate 20% extra power just by the tiny about of light that creeps through the cracks between each solar cell … given that the cells on the back will only be generating by the light that’s reflected off the roof tiles? 🤔

There are 6 South East facing panels with at least one shaded by a dormer window in the early morning. There are seven South West facing panels with a large chimney stack shading one or more sometime in the afternoon. Today was a poor day for the array but I can tell the output for each panel and the best panel produced twice as much as the worst.

Very disappointing indeed. I suspect the heatable guy paid for this presentation.

[@WyndStryke]

The bifaciality gives about 5% extra apparently, if installed on a roof. It'd give quite a bit more if installed on a ground-mount or vertically. Regarding microinverters, I don't know about more inefficient, I think it's about the same as a typical string inverter, but I struggle to see their value if there isn't significant shading to deal with. Perhaps if there is a chimney or similar, put them on the nearest panels to the chimney, but I don't see the point of putting them on all the panels.

[@luc_libv_verhaegen]

This is far from the worst of it. One of the worst fully charged videos ever. But the bifacials are not bad, depending on how much of a premium Heatable charges for bifacials. Bifacials these days are almost on parity with standard panels for some solar panel manufacturers, so you get the advantage of having your silicon sandwiched between two glass layers instead of one glass and one aluminium with coating for the same price. But i seriously doubt that these snake oil salesmen are charging the real prices here.

[@kadmow]

- putting bicacials on tilts (or stand-offs) - can allow a bit more ambient back scatter collection- somewhat better cloudy day performance - probably better with a metal roof rather than tile.

[@luc_libv_verhaegen]

Why would anyone in their right mind spend 75-100EUR per solar panel, and then add another 130-150EUR for a micro-inverter per panel! The bifaciality here is just useless this close to a dark grey shingled roof, the only good thing is that these days bifacial panels are on price parity with normal panels, so it should cost nothing more for panels sandwiched between two layers of glass.

@@benbocc1549 low voltage start up is even easier to achieve on some string/hybrid inverters than these micro inverters. The Goodwe ES G2 for example has a startup voltage of 58V and an mppt range of 60 to 600V. With several panels in series, this hybrid inverter will achieve 58 and 60V faster than a micro inverter can achieve 20V on a single panel. Micro inverters have their places, especially in installations with extreme shading problems. Why this heatable guy is desperately advertising them for what they are not meant for is most likely a matter of pure greed and selfishness.

[@edc1569]

@@adon8672 yes its a paid ad

[@luc_libv_verhaegen]

@@benbocc1549 I am not sure low startup voltage is that useful really. This is just a carrot to sell more microinverters. You want high string voltages to keep the amps down to reduce friction losses. You also want high string voltages for more efficient inverters. Take a look at the victron inverters for 12V, 24V and 48V systems. Notice the price difference between the respective voltages for the same power output. They are more priced per Amp as per Watt between these 3 voltage standards. Panels have an inherent voltage even when not generating meaningful current or power, this depends on the number of cells (shortcircuit voltage). Once they get insolated they start generating power, but how much power and at what exact voltage (and thus amperage) varies on many factors. Therefor every modern solar inverter or charger has one or more MPPTs built in. These trackers constantly adjust the voltage to be able to get the maximum power out of your panels. Inverters and chargers come in different shapes and sizes and different MPPT ranges. Imogen claims to give us a science lesson and then states that some hypothetical big string inverter has a starting voltage of 200V whereas these microinverters have starting voltage of 20V, and then claims that the lower starting voltage means a bigger "range". Total nonsense. She is talking about completely different things. You can have a big string inverter with a starting voltage of 200V and a maximum voltage of 450. And you can have a single panel inverter with a starting voltage of 20V going to 60V. The big inverter then has a way bigger range (250V), and the smaller inverter has a range of 40V. So nothing of what she claims to be "Science" makes any sense. The advantage of having one micro-inverter per panel is that you have one MPPT per panel, and can track the maximum power point on a per panel basis. And that is the only advantage. Everything else is a big disadvantage, from price, complexity of installation (and with increased complexity comes increased failure rates) and efficiency of the whole system. You might get some more power out of some panels from time to time though, but this is not true for this installation here as there seems little in the way of shading. This whole film is paid for nonsense fluff. Almost no-one needs a big solar array with micro-inverters and enphase only has a business because of low knowledge customers with too much money to burn. As soon as enough people catch on, enphase will go out of business unless they can actually scale their company down to serving only a few niche installations.

[@fintrollpgr]

Even if the panels have lower voltage they might start producing at about the same time with a microinverter as with string inverter. As for the string inverter all voltages from the panels get added up anyway. Also Enphase microinverters are shit for most panels over 400W, they just can't get the most of such panels. I'd rather get Hoymiles microinverters. Also no use pretending Enphase is special, what he describes are microinverter advantages in general.... This is a commercial...

[@Yanquetino]

It's been 14 years since I installed our solar, which paid for itself years ago. What concerns me is that the temperatures are getting so hot in the summer that my array can no longer keep up. I fear I'll have to swap some of the original panels for newer ones that are much more efficient.

[@kadmow]

Microinverter systems also allow staged roll out of solar to meet needs / wallet - even adding different panels later down the line - as technology changes - string inverters are only suitable for the whole "adequately sized" installation. (NSW central coast - patchy rain today - Spring, solar faces NW - topography reasons - 24kWh produced - 18kWh exported between 6am and 5:45pm - SE string inverter with optimisers.) Power companies are fighting back hard to reign in the ca$h drain to residential solar owners - governments are facilitating the clawback (fortunately my household has been well into the cash positive territory with solar over the last 6 years, while power ($$) rates have increased at least 50% - of course it took a capital investment, 6 years ago savings was paying negative rates and the stockmarket was going sideways - I see it as a great investment..)

[@chrisconklin2981]

So, if I had a patio, thirty feet from the batteries, If I used micro grid inverts for the roof, the sunlight hitting the concreate pad and the ambient light would add to the total.

Yes, but normal DC bifacials would also work, feeding into a small string inverter just for the patio (cheaper than the microinverters + envoy unit).

[@chrisconklin2981]

@@WyndStryke Cheaper is not necessarily better. The issue is voltage drop. Depending upon wire gauge, over greater distances AC has less voltage drop, as T. Edison learned. To be clear, I do not know the answer.

[@WyndStryke]

@@chrisconklin2981 For a short distance like 30 feet, there's not much voltage drop (on either AC or DC) given a reasonable wire gauge. You should be able to use 4mm DC cable without any issue. If you were going longer than that, then 6mm. At 90 feet then you might need to transition to 10mm cable if you wanted to keep under the 1% voltage drop benchmark. Even with 10mm cable, it'd still be significantly cheaper than using microinverters ... and there's no reason to be using DC cable in that situation anyway, you can put the small string inverter in the patio, and just run A/C from the patio back to the consumer unit (what's what I'd be doing). The reason I'd run A/C is not the voltage drop, it's that A/C joints are more tolerant and don't arc in the same way.

OK you'll get some light coming round the edges, but still. Unless I hear otherwise I'll assume that 20% from the rear face is relevant to frame mounting on the ground or a flat roof, and the benefits of bifacial on a pitched roof are negligible. As an installer I'd also recommend not to have micro-inverters up on the roof when you could have a string inverter in your garage or loft, unless there's significant shading issues.

Other guests it seems are chosen for their ability to instantly do the confirmation bias thing for Robert's views. As is now known sales of BEVs are now in decline. It was an experiment which failed, mainly because the general car buying public didn't appreciate the initial costs, time to recharge and dismal residuals. And of course the possibility of self ignition with some lithium tech. Doubtless this will provoke arguments but the only viable technology left for reducing the carbon in our atmosphere is hydrogen. We read scathing comments apropos the suitability of hydrogen as a fuel from those who simply don't keep up and post history lessons. This is despite car manufacturers developing hydrogen powered cars using "off the shelf" fuel cells almost, deemed to be perfectly acceptable to power cars.

This means that an escape of hydrogen gas into the atmosphere will rise up so fast in the air ocean it won't have time to mix into an explosive so to speak, unless confined of course. If you were to research the Hindenburg airship disaster you will find there was no huge explosion. The airship burned but did not explode. The fire was a result of the dope covered outer sheath burning in air. The hydrogen gas had risen so quickly it no longer posed a risk of explosion. Ergo you have little understanding of hydrogen science. You would have been wise to research all this prior to posting. Now, hydrogen cars requiring a buffer battery to allow for acceleration from stationary ... so what? The fuel cell will be charging the battery as the battery discharges through acceleration. Again, so what? Hydrogen fuel cell cars have been working for over a decade, as in the Marai. Recently fuel cell cars and buses were to be seen in Paris providing logistical support as in transporting competitors and official to the various venues. In short the French wished to parade their "green credentials" to the world at large. The hydrogen used was reduced by green energy to. underline their attempts to be as green as possible. Again you could have found this out for yourself prior to posting if only you had applied yourself, but you failed miserably. BEVs are now in decline and unless such a BEV can be "invented" which is "cheap", can be charged in minutes to provide similar "performance of operability" to a petrol/diesel car then they are destined to be a mere footnote on history. What Robert will find in seminars yet to be is that increasing numbers of people will be asking about hydrogen fuel cell cars. It may be Robert has gone too far in "poo pooing" hydrogen he will find it difficult to start proclaiming them as the future, as they undoubtedly are.
