So if they are moulded into it? How difficult is it to change them should a panel be defective?

[@johnbelesis]

a scenario from hell 😂

[@markhill485]

The moulding around panels can be removed and that one or multiple panels can be replaced.

[@iKvetch558]

He said at 3:37 that the solar panels are "integrated into the actual gelcoat of the moulding", so wouldn't that mean that you could not just replace any panels by removing the moulding? Wouldn't that mean you would have to remove the gelcoat to get the panel(s) out, and then reapply the gelcoat when the new panel(s) had been put in? Am I wrong that that is not a quick and easy job? Or is removing and replacing gelcoat a pretty easy and quick thing to do?

[@TheocraM1991]

why don't install 3-4 windturbine to produce electricity in the night or cloudy days?And install a kitesail to earn 2-3 knots downwind?

[@TChalla007]

I'm confused. Maybe because this is a different boat. But "Sol" was reviewed by the Boat Show and said the eco 80 could get 300 miles on batteries alone at 12knots. Just realized it doesn't have a 1 MW batter bank. The question is, why build this 80 and not put a 1MW batter bank in.

[@paladro]

price point maybe, but a fair question.

[@idib1739]

CORRECTION: The "80 Sunreef Power Eco" & The "Sunreef 80 Eco" aren't the same vessel. One has a sail the other one doesn't. You Welcome 👍.

[@origin178]

Why does the flybridge roof not extend the full beam of the boat? Looks like it would double the panel area and make up (partly) for the hopeless range. Perhaps with future battery chemistry they'll be able to economically fit 1 MWh and give the boat more practicality.

[@TChalla007]

The eco cat "sol" has a 1-megawatt batter bank. it was reviewed by The Boat Show. It gets 300-mile range @12 knots on batteries alone. I don't know why someone would spend all this money on an 80 cat and not max out the batteries.

[@Pomelu]

[@felicytatomaszewska]

I prefer the sail echo yacht that combines solar panels with sail. That has travel much faster due to sail and also use regen through propellers to charge the batteries in addition to the solar panels thus practically eliminating the need for range extenders though I would still keep them for redundancy in case of emergency. Sail are a lot more efficient in harnessing the wind energy to propel the boat while solar panels can take care of the hotel loads.

[@alanbutterworth4219]

Brilliant. For about a hundredth the cost of this boat I'm completing a 40ft power catamaran that will have a 6kW solar array, two 15kW electric outboards, two 45kWh LiPO4 battery banks and two 11kW solar inverters. I guess if I was a billionaire, this would be the boat I'd buy.

[@anthonybariek997]

I know they said on solar power it could cross the Atlantic but at 4 knots cruising speed, thats nearly 5 months, can it hold that much in supplies?

[@ianscott3180]

I stood behind one in Denia. It was moored stern to near us. Up close, you really do get an idea just how big they are. This was a normal diesel engined one. It was suggested that it belonged to certain Spanish tennis player, I cannot confirm that.

For longer distances this boat will also start the range extender, but when one is a location and not moving a lot, the solar panels and batteries can save a lot of diesel and noise.

How do you repair a side panel?

solar panel would worry me maintenance wise. are they even replaceable in this case?

[@TChalla007]

[@virtualmage0]

@@TChalla007 issue is they state in the video that the panel are embedded in the structure under the clear coat. so it would make panel replacement quite costly down the road.

[@TChalla007]

@@virtualmage0 I pretty sure the longevity is worth it. They can last up to 20-35 years. I'm pretty sure Sunreef R&D dept understand the consumer's concern. The panels are layered on top of the surface, probably recessed a cm or so that's also why they're flexible.

Great tour, great yacht. Thanks so much. Solid state batteries in a year's time willl be a game changer for this type of vessel.

[@Pixelplanet5]

unfortunately solid state batteries are still a very very long time away from being substantially better than what we have today and also for a vessel like this it wont matter much how much energy you can store in the batteries, what matters is how much you can regenerate in the shortest possible time. this boat would be much better if they didnt try to mold small solar panels everywhere which you can never replace when they degrade in 20 years and if they designed this boat with solar power in mind which means a very large flat top to maximize the area thats available for solar power. this boat has so little solar power available that they included HUGE fuel tanks and dont even list the peak output on their website cause they know its not gonna be great.

[@cobra64th21]

Solid stare batteries are a huge improvement. They are half the weight fir the same energy storage of lithium. Less weight means less energy to move.

[@elmarco777]

So if you can run on the batteries for 4 hours, and you can charge the batteries and sail at the same time. How long do you have to run the generator until the Batteries are full and you can run on the batteries for another 4 hours?

[@divox9pqr]

I like the centralized position of the fly bridge on the 2nd level. I would hope that the helm station would also be in the same position on the main deck.

[@NoseNuggets]

None of these pure solar yachts seem to get into the actual, practical details of daily use on a 2 week cruise. Not even a passage, just island hopping, stopping every day at anchor. How often did you run the AC, and how often did you run the gen, how many miles did you move a day? How many kw did you gen, how many did you use?

[@cobra64th21]

Yup everyone of these type of yachts needs a sail. It's stupid to not use the wind.

[@adiaz2494]

One thing that other manufacturers should consider from this is the solar panels on the side overhangs of the superstructure, not for propolsion but to lessen the need of running the gensets.

[@kamingcloud2880]

Awesome Dream Boat !!! I imagine instead of using diesel for electricity back up power, I wish they also can able to build hydrogen fuel cells power to capture all that free hydrogen from the sea water, enabling the boat to cross any oceans in the world. With renewable energy Solar, wind and Hydrogen power together, now, that is a environmental Perfected Dream Boat ! Let hope someday this will happen ? 😉💖🌬⚡️⛵️⚡️💖🔋🌞💯🌏✌️

[@HansKeesom]

Hydrogen is not very efficient. You need batteries for that. But when batteries are filled you might produce some hydrogen and store it. Hydrogen can store more energy in a certain space but that benefit goes out of the window partly because of the high losses while making it.

[@michaelnewham6958]

I love what your doing and the idea of utilising more surface area for solar generative power is the way forward as the water reflecting the light idea is 💯! The scale of the boat is great and price range competitive. Personally I prefer the silent yaught as yours feels cramped. I think the designing of both companies interiors could be pushed in a better direction. Silent is too ikea looking and as this is the only boat I’ve seen from you, I still think less is more. There just seemed like too many cabby holes and I found some of the designs ugly. Including the motor space. For me there is just too much on show but for others I’m sure it will be a success. I loved all the brass coloured finishes everywhere Keep going, it’s all a journey. I hope solar rules the waves soon Godsped X

[@SimplestUsername]

This Yacht would look much better with a dark gray exterior. Though, I have a feeling that having the solar panels stand out is more important to these people than a good looking Yacht.

If I had the money /eurojackpot ticket active.../, I would go for one customized to my taste - bit smaller 78", all enclosed like a greenhouse/diamond shaped so there is more closed up comfy space and more surface to be a floating power plant with excess electricity provided while not moving. The excess electricity would be used to store energy in hydrogene tanks to feed a fuel cell power generator when needed. Put a big office/computer room in it, double and triple redundancy, minimise maintenance, more spartan outfit as this looks and feels for me too blingbling...and some storage for non perishable foods and freezers..... and a tender that can be used as lifeboat and ideally amphibious to go on land and deliver goods directly.... thinking of something like the german Schwimmwagen but electrical

[@pred7949]

[@charlesbrightman4237]

QUESTION: Why not a Hydrogen Fuel Cell added to the boat? Utilize the solar cells to split water (H2O) into Hydrogen and Oxygen, stored separately. Recombine the Hydrogen and Oxygen in a Hydrogen Fuel Cell to get the electricity back with a by-product of basically pure water, of which, can be re-split and re-used over and over and over ........ And 'if' one did not want to store the Oxygen onboard, then utilize the atmosphere to store the Oxygen. As long as one had solar energy, and basic water, one basically has an endless fuel supply.

[@charlesbrightman4237]

Also, this item from my files: (to utilize electromagnetic radiation energy frequencies besides those utilized in basic solar so as to have an endless way to recharge batteries, day or night): 'BATTERYLESS BATTERIES': To help power equipment in outer space: Potential endless energy source basically anywhere in this universe: a. Small aluminum cones with an electrical wire running through the center of the cones, cones spaced apart (not touching I'm thinking) but end to end. b. Electromagentic radiation energy in the atmosphere interacts with the aluminum cones. c. Jostled atoms and molecules in the cone eventually have some electrons try to get away from other electrons of which those electrons gather at the larger end of the cone, of which also creates an area of positive charge at the smaller end of the cone. d. The electron's in the wire are attracted to the positive end of the cone and the positive 'end' in the wire are attracted to the negatively charged end of the cone. e. Basically a 'battery' has been created inside the electrical wire itself, different areas of electrical potential. Basically a 'wire battery' or a 'batteryless battery', however one wanted to call it. f. Numerous cones placed end to end increases the number of 'batteries' in the wire. (In series to increase voltage, in parallel to increase amperage). * Via QED (Quantum Electro Dynamics) whereby electromagnetism interacts with electrons in atoms and molecules, one would have to find the correct 'em' frequency for the correct material being utilized for the cones. The shape of the cones could also come into play. The type and size of the wire as well as the type and thickness of the insulation between the cones and the wire would also be factors. * Of course also, possibly 2D triangles made up of certain materials with a conductor going down through the center of the triangle could possible achieve the same 'batteryless' battery system. * Plus possibly with the 2D concept, layered 2D's that absorb different energy frequencies, thereby increasing the net output.

[@bluepawn]

Solar panels need to be much more efficient for boats... The batteries as well. A Tesla car motor needs to be put into this boat for efficiency. How do you change the solar panels in 40 years ?

[@cobra64th21]

Probably have to take the clear coat off. You can use the money you saved on fuel. Which is like 60k per fill up.

[@robertsmith-fj2rx]

Unlimited range at 4Knots… LOL. Except at night on a long passage or during raining or overcast days. Then add inefficiency of solar panels with partial sun cover or limited daylight hours in winter. A feel good day charter boat or short trips with every night at anchor is really all it would be practical for. Can’t wait till the cells in the imbedded solar panels start failing either. No way i would want to cross an ocean in one.

Fascinating. I don't know if I like it but it is a lot to think about it. I don't really like the white and gold design, but mine would be laid out how I like. There are all sorts of hidden costs, as in maintaining the solar panels. The solar panels also usually need to be cooled, so how are they handling that? What sort of batteries are they using? Lithium ion are not to be trusted, I've had two very high end laptops go belly up with Lithium Ion and two phones. Nothing caught fire - but they ruined the devices. Lithium Iron Phosphate seem to be a better choice. It most likely handles heavier seas with same as any other Sunreef 80. I tend to think that hybrid powered boats like this are the future. But there are a lot of details we don't know and aren't being told.

If you travel at 6 knots you can use only solar power, but if you travel faster, you will need to run generator to recharge the discharged batteries.

Advertising this as "Solar Powered" is misleading. This vessel only has a very short range on battery power and not much more with solar assisting the batteries. the only way this ship has long range is..... with the "Range Extenders"... diesel powered generators. Silent Yachts also tries to pull off this misdirection. This is my favorite Sunreef but you should be honest in how you advertise for it. To be honest this vessel is "Solar Assisted". The only semi-truth to "solar powered" is that the vessel can function while anchored on solar and battery power alone.
