SILENT 80 - Energy Generation and Consumption

The goal of this video is to give provide and insight into the generation and consumption of the solar powered drivetrain of a SILENT-YACHT.
We will take you on a two day trip in order to showcase a variety of realistic scenarios, based on the SILENT 80 E-Power +. It will show you exactly how different situations affect the production and overall energy management with the help of the solar panels, electric motors and lithium battery banks on board.

They should partner up with tesla and uses there new 4680 cells that should have a 14000 to 30000 life cycle that would be the main reason who wants to replace all of those batteries 10 to 15 years from now plus the addition of a higher wh/kg density

[@nathanpaul88]

I wonder if the limit factor for silent yachts currently is the cost of batteries or just the energy density?

[@SunnySTX]

@@lesstevens2370 Actually they should partner up with Enphase! Microinverters would be extremely beneficial in this situation as each panel has its own inverter and acts separately from other panels that may be in shade or facing the opposite direction of the sun. Enphase battery tech is on par if not superior to Tesla at this point.

​@@Unstoppabletravel Hi - this is Michael from Silent Yachts - we received a feedback from one of our owners who does charter with his Silent 60. He had a demanding and experienced client on board, who already tested a Sunreef Eco before for 4 (four!!!) weeks and will go on another Sunreef Eco for another 2 weeks to find out the difference. Here are the numbers. 14 days charter, 240 miles, about 1.000 kWh generated by the sun (1 week they had cloudy weather, normally they would have produced about 1.400 kWh = 100 per day). Aircon on every day - day and night. Every day cooking on board, 3 meals, electric tender charged on board, watertoys. They had 7 generator hours in 14 days = half an hour per day (generator produces about 100 kWh per hour. Average speed while cruising 8 to 8,5 knots (consumption would have been less than half at 6 knots - no generator would have been required at 6 knots!). These are the true numbers recorded in August 2023 on a Silent 60, which we produced in 2021. The gen only had been started every second day during cruising for one hour, never in a bay and of course never during the night. Same distance covered at a lower speed of 6 knots would not have required using the gen at all. Right after this trip the client has booked on a Sunreef 80 Eco. His short summary - "the Sunreef is a nice boat, but I did not have even one "silent" night - the generator had to run every night, it kicked in at 3 or 4 in the moring and had to be started during the day for a couple of hours as well during cruising. Guess which boat he decided to buy? Best regards, Michael

[@CapeBojeador]

I watched the video and looked at the specs for the Silent 80 3 deck closed with 2 X 340 kW E-Motors, 429 kWh Lithium Battery and 2 X 145 kW Generators. Based on the information provided, I would expect the solar panels to generate a maximum of 125 kWh on a good day. That that is sufficient power for 1 hour of motoring at 20% of max power assuming using no other power onboard. Motoring at 20% power the fully charged batteries will give approximately 2.5 hours before the batteries reach 80% discharge. Charging from solar only will require 2.5 - 3 days to fully charge the batteries, assuming no other power is used during that time. The Generators running at 80% capacity will 108 kW each, assuming 10%, assuming 10% loss in charging and recovery from the battery, that gives 97kW to each drive. That would mean running at 28% of max power assuming no other power is being consumed on the boat. While this is a boat may be suitable for an eco warrior who is prepared to forego speed, range, aircon and other conveniences in order to minimise carbon footprint, don't hold your breath waiting for an ocean crossing.

Dear Mr. Michael, I really love watching solar yacht. I hoping to see it sail in Philippines. This is very expensive for me to buy the yacht. just seeing it sail is so great.

[@remosito]

@SILENET-YACHTS : putting this here as it's about energy consumption. Though I think the info was in another video. Mentioned was that at 6kn it's 20KW and at 8kn it's 40KW and that it raises pretty steep until it flattens out thanks to approaching and reaching planing speed. Have you ever experimented, either theoretically in computer simulations, or practically, with foils. They do add some resistance at slower speed, but create lift and thus let ship lift up and reach planing at lower speeds. Depending on how low a speed planing could be reached it could be worthwhile. Say it uses 25% more at 4kn and less , a wash at 6kn, but then brings down the 8kn energy consumption and above by 25%...

[@keithprice3369]

I like the idea. But it also means more mechanicals that can break down and increase maintenance costs. There's also the extra weight which would lower efficiency, I assume. And probably would take up living space, too.

[@SAINT-ANTONIO]

It's a great step forward for human kind to have solar driven yachts! I think catamerans are on the next step of evolution with independent food production, like Hydroponic or small Aquaponic food growing systems with round ecodomes on top with solar cells on top and sides to have tomatoes, potatoes, salads and whirlpool size Aquaponic tank ! Atmospheric water generators are maybe less energy consuming. I also think that ships are an exellent solution to survive on the Seas of a post Nuclear War on land and some water areas, because the vastness of the Oceans would diffuse it faster then on mainland. Ships would need EMP safe electrical system and some rooms emp isolated. Air & water filtration from radioactive isotopes Geigermeters Independent energy, water and food peoduction and space for bigger stock!

[@silentyachts]

Thanks!

[@gaspipe1]

I truly think that this will be the future of yachting, especially for liveaboards. Imagine removing the ICE generator and fuel tanks to allow more space for battery storage. Combining the kite sailing ability should allow for a) more efficient travel, b) allow regenerative charging and c) offer storm kites. Another idea is to perhaps allow reverse flow charging from electric toys to battery banks (VTG), even if this allowed 5 days of essential equipment usage in the middle of the ocean, it's bought time till the sun comes out. Very curious how this yacht would handle during a storm and no electricity due to a few days of stormy clouds.

[@silentyachts]

Hi there! A detailed video with the kite will follow soon. If you are facing stormy and unfavorable weather conditions for longer periods of time, there is a back-up generator on board which recharges the batteries whenever needed.

Hi Craig! Thanks for the kind words! It all depends on the weather conditions and energy consumption. For a general rule of thumb, a cruising speed of 6 knots during sunny weather conditions keeps you in an energy equilibrium, resulting in virtually unlimited range.

[@mlanyan]

It's love at first sight, i LOVE the yacht! However, I believe adding wind power with vertical helix turbine would increase it energy source continuously day and night, rain or shine, increasing efficiency and extending its range. It would be great to learn about how you manage the disposal of waste and the grey/black water, are they stored on board and discharged at ports? Thanks.

[@silentyachts]

Hi Martin! Thanks for your kind comment! The issue with wind turbines is that they create shade on the panels and therefore overall decrease the energy production of the yacht. Yes, the grey/black water can be stores on board and discharged at ports.

[@notdolandark]

If you can handle a boat this size by yourself this is the most introverted yacht possible you don’t even have to go back do the docks

This was great. I have a few questions: 1) wouldn't buckets be more efficient than screws? 2) Why aren't there any use of vertical wind generators? 3) What is the future? Are you looking at new/different battery technology? Upcoming solar technology?

[@manofsan]

wind generators would add drag to the vehicle - that's why I don't stick a wind generator on my car either

[@silentyachts]

Hi! Thanks for your questions! Vertical wind generators throw shade on the panels, therefore actually decreasing the overall energy production of the yacht. In addition, they are quite noisy, and depending on the position, can be a safety hazard as well. Regarding the future, all the key components of our yachts such as the solar panels and batteries can be easily exchanged. Therefore, a SILENT can be upgraded over time and benefit from the latest technology.

Is the Airco of the type that can work directly from solar, so DC power? Could save a lot of energy. Would be great when (some rows of) the front panel could slide forward and down, revealing some more panels to create a larger charging surface when at anker, with the ship turned into the sun. It would also make the ship more aero dynamic when sailing into the wind. Off course there is a problem with visibility at that moment, but one can steer the ship from the flybridge or when out at sea on camera images when inside. The interior of this boat is very nice, also because of less levels in the floor and windows.

Hi, wonderful vessel and clear explanation. Is there any equation r graf to calculate a 24/7 navigation without using generation? Thx!

[@silentyachts]

Hi! Thanks for the kind words! It all depends on the weather conditions and the energy consumption. As a general rule of thumb, when cruising at 6 knots during sunny conditions, there is an equal amount of consumption to production. For the SILENT 55 & 60 this means less than 20 kW.

[@linush.3598]

@@RogerWilco1 Well, this boat is only going to be 100% electric when it is island hopping or traveling along a coast, anchoring. You are right saying that long ocean passages will need the help of the generator. Using the generator though, the yacht is easily capable of crossing the Atlantic (as done with the silent 64) and possibly even the pacific? Based on my calculations, the boat should have a range of approx. 3000nm on diesel alone. With some good weather, this should extend to at least 3500nm.

[@RogerWilco1]

Linus H. The 64 didn’t cross just on its generator but with a bunch of extra fuel aboard. Again I want to know the numbers, because when I asked deteiled questions of their sakes contact, by my calculations the range was way too short, but I was estimating faster than 4 knots. 4 knots is very, very slow. So slow that you will be pushed backwards by a stuff breeze, or 4 knots of current. If you are in the tradewinds then mostly the wind helps you, but that works against you going the other way. My only objection is that they dont make these limitations clear.

Kite sail. The wind at 100 meters above the ocean is way more powerful than at the surface

[@RogerWilco1]

John Lions Kite Sail seems like a great idea. I asked them about it and thet are using some companies product, but that company gas posted no evidence it is a real product that I could see. They just had a demo of people manually flying a kite attached to a much smaller boat. It’s a huge effort to bring a product like that to market and a lot bigger kite to move an 80 foot boat than a 23 foot boat. And the silent isn’t a light boat, even for 80 feet.

Is there a better spreadsheet of this? What are the solar panels bringing in on perfect conditions to what is being consumed to what is being banked? this video is dreaming numbers up and consumption and generation have zero bearings! what is the bank capacity, what is the max kWp from solar panels, and what is the kWh consumption? for example, you have AC running well that would be huge kWh, and in no way would your solar be bringing in a positive charge to the bank and run ac on the whole boat. hope to hear back.

[@silentyachts]

Hi Justin! The peak power production depends on the models. The SILENT 80 displayed in the video produces 26 kWp, enough to power the AC on board and the propulsion system. Battery capacity on this model is up to 429 kWh. Feel free to check out our website for more specifications on the model (www.silent-yachts.com/silent80). If you are specifically interested in the technology (www.silent-yachts.com/technology). For more details, you are welcome to send us a mail at [e-mail]. Our colleagues will be happy to provide more details.

[@viasevenvai]

I think to advertise to the dreamers you should be more daring with the objectives. Bay to bay for dinner is nice but I’d like to at least visualize myself testing the CE rating of “A” out in the wider ocean, passing sailers in dead wind etc. A large living room trolling slowly around in the bay is obnoxious in my opinion, at least for the “let’s visualize how you’d use this.”

[@silentyachts]

In this case you might want to watch our SILENT 64 Atlantic Crossing video: kzbin.info/www/bejne/e3u4n42ijqmCiqc

[@keithprice3369]

@@silentyachts That's the right idea. But a 3 minute video about a 5,500 mile crossing is woefully inadequate. We're hungry for enough info to live vicariously. 😁

If you could equip the yaht with hydrogen electrolisys system and a fuel cell instead of a diesel generator and the diesel fuel tanks, then you could save much space and weight and get the maximum from the sun, as during cruising you could use kyte and generate hydrogen at once, then during the night you could go faster using reserves of hydrogen or as alternative fuel source. PV can be twice efficient using other spectrums of the light and if watercooling the pannels, their efficiency won't be affected so much by the temperture, that also would reduce heating of the inner living spaces and save electricity for airconditioning, while collected heat could be used for hot water for showers and kitchen and washing machine, which could get a hot water instead of boiling it by electricity, same is for dishwasher. Condensed water coming from the air conditioning could be used for washing machine and dishwasher or for flashing toilets. Kyte can have wind turbine installed within and transfer electricity generated by the wind, which can be combined all together with its pulling power received from the wind. What I really can't get is why use toilet paper at all on a yaht for 5M€, when there is a bidet seat available for more than a few decades, preheated water and a fan instead of the paper?

Hey new content 👍

[@silentyachts]

More to come for 2021!

[@LuanSilva-zd4qv]

seria interessante algumas turbinas eólicas para uma produção de energia durante a noite ou até mesmo como um sistema sobressalente aos painéis solares como um sistema que manteria alimentado as baterias da iluminação e navegação de forma isolada por razões de segurança por exemplo...

[@Fightback2023]

The energy generation rate and stats are very very amazingly fast...which I'm really questioning it.

[@hylje]

A quick Google search suggests typical solar panel efficiency is about 150W/m2. To achieve the shown surplus of +10kW, you will need at least 66m2 of solar panel surface. Eyeballing the dimensions of the solar panels shown on the boat seems to fit at least that much. Also from the shown power usage, it seems the propulsion engines are quite diminutive at 12kW each. But they will probably do the job perfectly well for quiet, silent cruising in relatively unchallenging waters.

[@JamesJones-cx5pk]

We shall see. How often do the batteries need replacing? Solar panels damaged by storms/hail?

[@silentyachts]

Hi James! Thanks for your question. There are 8 years of warranty on the battery banks. Within those 8 years at least, there will be no reason for exchanging the battery banks. In case you would like to take advantage of the latest battery technology being released in the future however, you have the possibility to replace them the of course. From a technical / reliability point of view however, the batteries will last you for many years to come. In terms of storm there is no reason to be worried for the solar panels. We have experienced light to medium levels of hail with no damage on the panels. Rest assured though that we provide 25 years of warranty on the panels.

I wonder if a small windmill could or should be placed somewhere on yacht , almost always wind at sea

[@shawnp3901]

Maybe one day I will be lucky enough 🙂

[@silentyachts]

We surely wish you all the best!

[@robertodulio817]

How about adding a small wind mill to assist generate power on both side of the yatch

[@wjlambert]

The Specifications on your website for both the 60 and 80 Silent Yachts is confusing on the fourth page down... Why does it show "Fuel 1000 - 1900 L" on the 60? and "Fuel 3000 to 5000 L" On the 80? Are these not Solar Electric? Where does one put liquid fuel? The 120 model does indicate a kWh rating for the fuel source

[@silentyachts]

Hi Wes! Our yachts are solar electric. They are also fitted with a back-up generator, which can recharge the batteries whenever needed. This is only a back-up measure however, as the yachts fully function without it.

[@carlosLL88]

Michael, thanks for your video. Could you please tell us what is the average consumption kw/h at 6-7knots? Keep uploading videos. Thank you guys!

[@michaelkoehler1077]

at 6-7 knots we are below 20 kW with the Silent 55 and Silent 60

[@julien3083]

I am really curious if you could replace the batteries with a hydrogen system. But I suppose the efficiency isn’t great enough yes right?

[@silentyachts]

Exactly!

[@LorenTedford]

So I have a Quantum Q6 HD Edge wheel chair its about 350lbs just for the chair and about 13k for replacement was curious what kind of handicap accessibilities are in this boat and if there isn't any could it be modified enough to handle handicap accessibility issues.

[@mikehuge577]

So it's only good for day island hopping, not long passages?

[@Philipp_f]

What happens when nobody is onboard and the yacht is in the harbour? Do the solar panels give the electricity ashore or what happens to the unused electricity?
