You want a wider area to catch more of that sweet solar energy, right? However, bifacial vertical solar panels have started to gain traction recently. Their more flexible-footprint has innovators in Canada, Norway and elsewhere testing them in all kinds of weird scenarios. People who are using these panels are reporting something odd - higher energy yield than expected. The extra yield stumped engineers, but a recent Dutch study may shed some light on the source of this extra energy. Have we been doing solar panels wrong this whole time, or is it all just a miscalculation? And how could this tech impact our lives?

      I have been watching a number of videos about people sailing on catamarans and most of them use bi-facial cells on the back of their boats since so much of the sunlight can reflect off the ocean water.

    • @ab_ab_c
      @ab_ab_c 5 หลายเดือนก่อน +10

      So the lesson learned is install movable bi-facial solar panels that are automatically optimized for maximum energy output (i.e. before they become too hot, change their tilt & direction sufficiently to compensate for the anticipated undesirable thermal gain. When they cool down, optimize their tilt & direction again for maximum energy generation).

      Yes. A relative is furious about solar farms going in the fields within thirty miles of where she lives. She was fine with the massive coal fired smoke stacks which could be seen from far further away as her county is entirely flat aside from one city on a hill (Lincolnshire). Drives me batty. She's got solar on each of the three houses she's built but it's not ok to have it in a field for twenty years. I tried to explain why it's important but she doesn't get it. All she really cares about as a NIMBY is that she can see something that's not pretty. I despair.

    The reason why vertical panels are cool is not only the lower amount of heat they get but also the amount of convective cooling they get. Vertical panels facilitate the natural flow of heat upwards, while horizontal ones impede it. I.e. the amount of convection per surface area is higher on vertical panels, so they cool better.

      @@Will-xk4nm Warm air rises. It can’t not move. There’s a reason passively cooled electronic devices have their heatsink fins oriented vertically. If it didn’t matter they wouldn’t orient them that way. If the air didn’t move they wouldn’t be passively cooled in the first place. They’d need fans. But they don’t have fans. They don’t have fans because the convection from the air being warmed is sufficient to move enough air to cool them. I think every home audio amplifier I’ve ever had, save one, has been a fanless device with heatsinks that have vertically oriented fins. And the sole amp I had over the years which actually did have a fan in it still used vertically oriented fins and only turned the fan on when you were asking for enough power that you’d never hear it over the music you were playing anyway. That you think it is too simple of an explanation doesn’t mean it is incorrect. It might be incorrect, or it might not be. FYI, it is possible to present conflicting information without being a jerk.

    In college, we created a photovoltaic panel with water flowing behind it to cool the panel. It created hot water and an increase in the output of the panel. I’m not sure why this isn’t being used more now but it’s a similar concept. A cooler panel equals more electricity.

    This video neatly addresses a key dilemma: I have an asphalt shingle roof that has maybe another decade of life left to it, and I don't really want to put solar on it only to remove it when it comes time to replace the roof. I'm also replacing all my privacy fencing, and I realize I have two long runs that go almost perfectly north-south, making them ideal for rows of vertical solar panels. Meaning that even if I need to purchase several extra panels to meet my total energy needs, the savings on labor and fence materials should more than pay for it.
    Even better, this makes my solar installation a DIY process, as there will be no need for any roof-top work. On top of that, I expect to have less maintenance due to less deposition of our insidious San Diego dust that keeps blowing in. Win-win!

    • @Rainbow_Oracle
      @Rainbow_Oracle 5 หลายเดือนก่อน +10

      Not much of a dilemma I'd say. I dunno in your case, but at least in my area it's pretty normal for installers to offer free removals for your panels for whenever you need to change your roof. They only have to do it, roughly once every decade twice per house, so it's not a biggy for them to do that.
      And it gets rid of another silly petty excuse that people make for themselves to not go solar! Really taking panels off isn't that hard. Don't be lazy! The technical detail is mostly in just in drilling the holes, and making sure all the framing pieces line up and are screwed tight. Once the frame is on the panels just bolt onto it normally.

    It's hard to believe that the TNO study didn't have regular horizontal panels right next to the vertical ones. That makes it super hard to get a apples to apples real world comparison. Knowing the huge variance in solar radiance by location, I'd have a hard time giving this study the credit it would otherwise deserve. Thanks for having all the references in the show notes. Individual panels vary more than the 2-3%, but the fact they even produce close to the horizontal is impressive. Edit: after researching, they don't produce close to horizontal, just 2-3% more than they thought vertical ones would, due to additional cooling from having them mounted that way.

    One observation I have made is that installing solar panels on roofs over habited rooms made a huge difference in less heat pumped into the building and not only created electricity, but reduced room temps by 15 degrees! That means a HUGE savings in cooling that room! I live in a desert, sooo.. I am going to vertically mount some of my panels on south and west walls with stand off from the wall to allow convection to take away the heat and not transfer it into my walls... double improvement with reduced load on my cooling system AND cooler walls while I collect energy!!! 👍👍👍 Any cooling I don't have to do is a huge savings!! Yes, I'm kinda screwed in winter, cuz my walls won't get sun, but my cost is 8 months of cooling, not 4 months of heating. Now to gather data before the install!

It allows us to work easily through the rows of vines, and also if they are installed properly and we adapt the orientation of the panels to project its shadow to the vines, it could give more fresh temperatures allowing the plants to rest during the hours of major sunlight incidence and help to decrease the temperature of the plants during summer hot months.

      Think of it like this, if you lift a cook pot lid straight up vs lifting and tilting. The tilted lid lets the condensation run off quickly. It's the same with heat. Heat wants to rise so creates faster air flow up the side of a more vertical surface so better cooling. Also roofs are (sometimes by 50F) hotter than ground level air temps but roofs often get best access to direct sun. Lots of factors.

    I've been off-grid solar at home for more than a decade in Canada. In winter when the suns angle is barely above the horizon the "optimal" panel tilt is already close to vertical. I've been running my panels vertical for the last few years while there is snow on the ground and see better output. I've been attributing these increased outputs to the combination of reflection off of the snow on the ground and the lack of accumulation of snow/frost on the face of the panels. With the ambient temp below freezing the cooling is probably having an effect as well. On a -30C sunny day the array exceeds it's rated output significantly.

We have done an experiment on a building, where we put bifacial panels on a horizontal lattice running up and through convection underground, pulls up cool air across them which worked well until the vacuum and modules were broken by a grass cutter hitting a stone hahaha, but worked great on keeping voltage high

    I have just taken my average small semi-detached house with limited land OFF-GRID, it has been hard work and in mid winter I have to be frugal. But two things nobody seems to think of is Cleaning/Maintenance and Snow coverings. One thing I will be fitting to make winter easier is vertical panels on my walls, some are of the type that have better low light performance. My advice to people is you really need panels on all elevations. One big problem I have is sunny winter mornings I have not currently got any panels that can harness this energy and what I find is in the winter frequently has the day progresses the moisture builds up in the atmosphere, clouds form in the winter sky by the time my other panels would normally be exposed. Yes fit South facing panels to start, but use West facing panels to catch the late evening summer sun so that you have plenty of power to run the washing machine when you get home from work. In the summer my North facing elevation is actually very well illuminated late evening, and I still do not have any panels to catch it. Multiple panels, multiple positions, multiple charge controllers, so that if one burns out you have plenty of built in redundancy in the system. Not yet got into wind, I expect to get a small useful amount on bad windy dark days, but not a lot from a small urban wind turbine, my other venture will be in Thermal electric to generate small power from my wood stove. A good idea is to think of your house has your own micro grid system, when sizing stuff, work out what loads would be useful and what amount of wind or solar could power those loads. Create multiple micro systems so if one goes down you always have back up. I actually have a rare old 12 volt only Petrol generator, so far this winter it has probably now consumed £20 worth of fuel, pitch that against the truly obscene standing charges, I used to pay for of £35 a month and its a no brainer.

      local conditions permitting, one could also consider creating reflective surfaces which re-direct sunlight onto some of the solar panels earlier / later in the day.
      like one commenter earlier wrote -
      they get extra yield from reflections off a nearby lake as well as a shiny nearby roof.
      another (albeit small) power source for blackout preparation or off grid living,
      especially when resources from solar + wind may dwindle during prolonged bad weather conditions:
      exercise treadmills attached to generators (I've seen TH-cam videos where people used old car alternators)
      heat generating appliances such as washing machines, power showers, kettles could be supplied with pre-heated water from stoves /fireplaces, which should reduce electric demand drastically if that were previously used to heat all the water.

    Using the land for shade tolerant plants is one way of approaching it. Another is to use the system to provide partial shade in otherwise desert conditions. Depending on how far apart tie rows are, you can limit the maximum direct sun. You could even plant different varieties different distances from the shade. Likewise, you could use the system, along with an open-cycle ground-water cooling loop and do three things- warm the ground itself as a hedge against frost, make the panels more efficient, and also facilitate irrigation. If you built extra strong foundations on the edges of a field, and suspended loads in tension, you could manage extreme winds by pivoting off the base while anchored, allowing the mass of the panels to dampen otherwise overwhelming pressure. In low wind, you relax tension and let the panels rest on the ground. You still have to build a line of supports along the way to collectively prevent swaying. You’d also use cross supports between rows. If plan for it, you could manage extreme wind by lifting the panels so they feather free, then lower the common cable again to confine the movement of the panels such that they remain in contact with the ground (likely killing some plants). The less effect the worst wind can do, the lighter and cheaper the whole can be. There would be advantages if the field posts required no permanent foot.

    Benefits:
    * Less issues with snow
    * Allows for ground reuse around the panels
    * May benefit crops that otherwise get heat soaks too much (great in countries like Spain where farmers place light tarps over entire fields, to reduce damage to plants from the too strong sunlight)
    * Longer lifespan?!! Anybody in IT or Engineering knows that more heat tend to degrade equipment faster. Reduce the heat not only increased voltage in panels but also may mean longer lifespan for each panel.
    * Saves space to put panels in spots you normally waste
    * Better for homes, as you may require a less big battery / you send less to the net, as demands vs energy production matches up more. A issue that we are seeing these days of people getting their solar panels cut off the net, by net providers as they are over producing during peak sun hours (and the net can not handle that influx). Note: Your also seeing more solar panels being placed north-east/north-west, as that is the new trend to double panels, partially south/south-west/south-east but also some for morning. In general, those panel give about 1/3 the energy of their south brother(spring/autumn) but that matches more household activity.
    Disadvantage:
    * More expensive as less mass production of dual facing panels. But frankly, those prices have dropped a lot already as dual facing panels are being pushed more, even for roof installations.
    Just like South vs North facing panels, the best is a combination of roof, vertical panels, in different directions, to create a more stable energy flow during peek moments, or increased production during dark moments.

    so, after some reading, I think these only generate more power than traditional PV installations once you get pretty far north, like the nordic countries, Canada, and Russia, because then the sun stays close to the horizon most of the time, and rises and sets much farther north.
    On the other hand, these are really good for reducing the need for grid storage (and gas peaker plants) because the double peak in the morning and evening is complementary with regular monofacial PV to flatten out the overall solar power generation curve. With how cheap solar is, that alone seems like a great reason to use vertical bifacial PV in more places, especially on houses and in residential areas where power usage at noon is very low anyway.

    I really like how this configuration overlaps with demand because the biggest problem with solar energy will remain to be storage. Added efficiency helps, and this sure adds different opportunities in installment methods and plans, but I feel like the core issues are still unaddressed
    Vertically stacking them like a tower sounds like a nightmare to deal with when different levels of shading are taken into account which tends to have catastrophic effects on output, but the idea of having panels integrated in plots of land doing other things seems very effective. I see the potential here (despite shading issues)

    Something I thought about a while ago when my parents got solar fitted was what about a water feed to wash the dust of the panels and cool them down on hot days. But then why not have the solar panels have a jacket built in with a solenoid on the bottom for drainage and one on the top for air bleed, a contact at the top to detect it is full and a water feed line. Then this could be run back to a cooling system that when it detects panel temperatures over 30C shuts the drain valves and opening the bleed valves as the panels fill with water. Once they are full the drain opens and water is pumped around the loop to a radiator. When it gets cold over night they can drain down to a storage tank so they can’t freeze. Or run a antifreeze coolant

    There are already solar panel banks installed vertically in Finland. Some residential apartment buildings might have their entire south wall covered in solar panels. It doubles as a surface cover, produces electricity and there is no problems with bird poo, autumn leaves, winter snow, or dust and other dirt. Another huge benefit in Norway, Finland, Canada etc. is that the vertical solar panels actually produce some power in the winter. Because the sun is so low for the whole day in the deep winter normally tilted panels, which are usually always low and covered in snow, don't produce much power. It's also much cheaper and easier installing and maintainin panels on a wall rather than on a roof. (Roofs in these northern countries are often rather steep due to snow loads and high rain accumulation). Solar panels are dirt cheap. The installation, electronics and electrical components are much more expensive. It just makes sense adding 100% extra panels for a vertical installation just for the heck of it if you have the space.

    Cooler temperatures improve panel efficiency. I've heard about that before.

This warmed water then feeds into the hot water supply of the building, saving some energy on water heating.

    4:33 The first thing I can think of is, maybe it has something to do with losing energy straight to ground when they’re that close to a surface. if you set a battery straight on the concrete, it can have electron flow through the casing to ground and discharge faster. You’re creating more potential by moving most of the panel away from earth ground. You could also gain performance by not having the panel heat up so much, and moving away from the ground would do that where they now have airflow. We can go with a combination of those two for my best guess. You might as well make different sections them spin around and create wind energy also. You could take the PV panels and put them vertically where they could waive as the wind blew on them. Use that same wave action like you do out at sea to generate electricity. We should change code for new construction, so that homes are built to collect and reuse energy in the most efficient way possible. Why combining heat from all your different sources to create hot water and energy. Why is it your computer and refrigerator not heating your water, for example. if we sat down and tried really hard, we could probably make much more efficient housing that still affordable. It may be less convenient, but too bad.

For more details, look up natural convection.

    As you explained part of how BVPVs work is because light is reflected off snow/roof/next solar panel onto the a solar panel. This reminds me of a years-old ad about a guy who paired 2 single-sided solar panels into a horizontal V shape so reflected light would bounce between the faces of the 2 panels. Because each ray of light hit each panel multiple times more of it was converted into electricity instead of being lost as reflected light. He claimed this significantly improved the electricity generation. He racked multiple "V"s into a vertical column thus reducing both racking needs and required space. He researched the most efficient angle of the V and for a nominal fee would send you his findings. I can't remember his name. Please investigate if this is true and is anyone doing it.

    One aspect only touched on here and not really fleshed out is the financial return for the more demand-correlated output of vertical farms. Power distribution pay (at least where we are) quite fluid rates that match their demands, its why the addition of batteries pay back far more than you'd think. While the total energy capture might be only 2.5% higher, the distribution better matching the higher rates you can get is actually a far bigger impact on ROI. We have done simulations based on data from the same study (those charts were horrifyingly familiar seen outside of a work context!) and almost 15% more money can be had, and that was presuming some very conservative price tracking. If you are considering a small-scale farm or even a domestic situation where you can sometimes get very variable reverse tariffs, you might see more like 30% gains by distributing double-skin panels vertically. One interesting side note though - if you do have the 20% higher up front costs (which almost all go into the structure by the way, not the panels which can be very similar from some suppliers), then you are still better off with putting that in storage, assuming the gains you want to make are from variable-tariff sale prices, and that's simply because the demand curve is not just at the beginning and end, its outside the beginning and end of the sunny times, and to get the supply to match that, well you need batteries - but if you have em, and have the wits to carefully control them, you can get a huge payback.

    4:05 good job. I know bifacial but they never mentioned this advantage until now. So you basically get good generation in the early morning and late afternoon but not noon. A side effect of this, due to less peak generation, you don't need to buy a powerful inverter just to capture a short peak of power generation around noon. Inverter cost is being left behind the rapid drop of solar panel prices. Additionally, in solar farms, you don't need a tracker that adds costs-we just need a large solar farm or solar pv company to confirm this.

While I respect the need for farming land in places where space is limited, I'd say avoid that idea in exchange for a mirrored convex reflective surface, even better than snow, on the ground between rows instead of grass, with perhaps watee flowing below that surface. Bettee performance involves capturing as many photons in every way possible, while also minimizing airborne particulate like from grass and dirt from impeding the photo-voltaic receptors, and flowing water below the curved floor surface would provide air and water cooled channels to optimize efficiency.

    After seeing this video I went out and separated two of my new BYD bifacials (the biggest panel they make) ran one vertically and one at 36 degrees south. Both were sent through a shunt and then the + and - where connected. When it got dark I went out and checked and the vertical panel produced almost half of what the panel set to my latitude did. My guess is this study was done so far north that the optimal orientation was closes to vertical with Norway being at the 66-69 degree latitude.

      You think like a raised 4 panel array is ugly but these lifeless straight line columns aren't?
      My understanding of beauty is in direct contrast to you it seems and I can obsess for unhealthily long chunks of time over flat straight and true, but, as they say, straight lines don't exist in nature and in buildings can easily lead to that sickly institutionalized feeling. I think vertical can have a place but I'm a HUUUGE fan of garden partitions and privacy screens and even with that, on their own, vertical panels look anemic and uglier than shit.
      I don't like panels on any roof that isn't south facing but thats cuz I think it's inefficient. Putting a post in the ground and panels 8ft above you isn't going to be cutting into most people's freedom of movement (assuming you have the space). Panels can even be arranged to look like flower petals opening up. Idk man, I'm really trying to understand here and I'm just coming up short
      Do you think giant windmills are ugly too? Because the majority of people think they look freaking awesome.
      If we were 18th century Dutch, would you have been against those windmills going up too? Progress is appealing, exciting. Conserving has a place, but if it's trying to conserve old customs that have no real reason to exist (like infant mutilation) beyond tradition, just accept that your ways are in the outs, in just the same way as your generation did to a number of your parents mores.

      Yup, I have pedestal ground mounts, too, on the farm site, and they look fine. Easier to maintain than roof mounts, too. But in the fields, these east-west bifacial verticals will look much better than a field full of south mounts. The fields full of south mounts on dirt where nothing grows cause shade, usually surrounded by a chain link fence - these arrays are a blight.on the countryside. Better than a coal plant, certainly, but I like the promise of this simple innovation for farm country.

    One detail not discussed that is very relivant - if you factor in the time of day value of energy generated vertical PV modules might be financially much better than horizontal. Even considering when battery storage is added into the equation minimizing generation of electrical energy in the middle of the day when the spot price might be negative is a major factor to consider.

    I am testing semi-flexible 60 x 60cm bifacial panels hung on the life lines of my 5 ton cruising sailboat. Not only do they increase output, but act as a barrier for wind, glare and spray. The next evolution is to maximize the 9m lifelines each side to produce enough to directly power the electric motor to move the boat at 4kts for free when there is limited wind. It takes 15 seconds to detach each 1.3 kg panel when sails become viable again. Innovation is the application of game changing technology together with several existing models. In this case… the recent availability of custom made flexible solar panels designed specifically for each user and their individual need. Mine were surprisingly affordable too. 13:23

    Turns out motorized mounts can get the best of both worlds to maximize returns. Angle perfectly until the critical temperature is reached, then adjust to east west vertical orientation until temperature drops back to optimal temperatures. Rinse and repeat. Definitely adds complexity and more maintenance to the system, but could work wonders for efficiency!

      Motorised mounts are more expensive than just getting more panels these days. I have a location where I was thinking of motorised because the panels can't be roof mounted, but it's shockingly expensive compared to a static mount. The idea of a vertical mount is very interesting to me because it is potentially even easier than a traditional sloped mount, because its mounted like a fence panel with just two end posts (subject to wind loading).

      what about mounting it at the top hanging down and the servo at the bottom tilting in +- 15 degrees at forenoon and then afternoon. Right in the morning, at noon and before evening it should stand just vertically. Such tilting should be quite sufficient. But the question is the overall daily surplus yield of energy, I would bet about 15% ?

  • @iRageGGB
    @iRageGGB 5 หลายเดือนก่อน +4

    i wonder how much more of a benefit it would be to run Vertical Bi-Facial panels with water cooling to pull more heat away from the panels into a water source for a building/home to use as a hot water source, then loop the cooled water from the building back into the solar panels. The building/home would act as basically a large heat exchange. I know Linus from LTT used the hot water from his panels to warm his pool, and the pool acts as the heat exchanger, would be interesting to see if, on a larger scale, this would be beneficial.
    Granted it would end up costing more due to plumbing requirements, but not having your hot water heater running constantly would likely reduce overall building electricity usage so might be a net positive.

    I didn't put my guess in the comments, but I guessed right.
    I have studied plant biology at the graduate level and its funny how this is similar to some of the tradeoffs plants have to deal with. Most plants photosynthesize at lower efficiency as the temperature goes up. This is both because of lowered enzymatic activity but also because high temperatures cause water to burn off too fast (causes leaf burns, xylem cavitation, general dehydration) -- plants respond by closing their stomata which slows the rate of carbon fixation.
    Plants employ lots of different strategies to increase their efficiency by reducing heat. These include white wax and hairs, as well as more vertical leaf surfaces, such as in many monocots when they are drought stressed.

    A friend of mine is already thinking about a solar fence around his complete garden. And i am thinking about a solution of wall-mounted vertical cells. Not for summer, but more for the winter, when the sun is low in angle, this would mean a significantly higher yield, when facing south.
    I must admit that the cooling factor is really interesting - never thought about it, even though the technical background is known well to me. 2mV/K can be a lot in a high amount of serially connected pn-junctions :) that can be easily add up to 30V difference in a string.

    I have build a PV "Carport" with Bifacial Panels. It is near perfect South facing and has an angle of around 20°. The panels i have are the LG360N1T-E6. At STC without Bifacial effect they are 360W panels. With the maximum Bifacial effect stated in the datasheet it goes up to 410W. Interestingly i can confirm that they out performed that by a long shot. I measured a maximum per panel so far at 440W. And i am certain there is still more possible. I would never guessed that they would outperform the Standard Test Conditions because i live in germany where 1000W/m² is definitely not a reality. So bifacial panels are definitely worth it in the right scenario.

      The only problem with taller crops will be the over all cost of installing it would out pace the return by a long shot. You are not just talking about getting over the crops, but also having room for everything else as well. Taller the infrastructure the harder it also has to work with weather such as wind, rain, and snow hitting them.

      It is a great option if you have the land. As far as damage to the roof goes, my panels have been on so long that the surrounding roof needs replacing, but the shingles under the panels are like new. Basically my panels protect my roof, not damage it. And basically most of my system, no one even sees.
