largest solar powered yacht

Silent Yachts

Creators of the world’s first series produced, solar-powered electric yachts.

Unlimited Range

Noiseless cruising, zero emission, minimal maintenance, pioneering solar powered yachting since 2009.

The Original Solar Yacht

As the original inventors of series produced solar-electric yachts, we pioneered this innovative approach. Our first model, the Silent 64, was launched to the market in 2016, several years before any other shipyard considered the possibility of going electric.

Leading Technology

Our founders began to research alternative energy sources to power yachts during the mid 1990s. Today, the technology of our in-house developed solar-electric drivetrain has been perfected and is multiple generations ahead in terms of reliability, performance and efficiency.

Historical Track-Record

In 2009, the Solarwave 46 was launched as our first prototype of a fully solar-electric, self-sufficient ocean-going catamaran. Since then, our electric yachts have cruised many 10.000s of nautical miles, performing flawlessly during a variety of weather conditions.

Enabling Self-Sufficiency

What differentiates a Silent is the unprecedented level of autonomy provided by our yachts. Being able to produce your own energy enables a fully self-sufficient lifestyle on board. Travel the oceans sustainably while making them your infinite playground.

The award-winning entry to solar-electric yachts.

Timeless design meets state-of-the-art technology.

What Makes Us Unique

The tranquility on board of our yachts is unique. A lack of noise, fumes and vibrations create a deep connection with the sea. Luxury and sustainability finally merged into a holistic experience, working hand in hand with nature by minimizing the impact on the marine environment without compromising comfort.

For optimal performance and efficiency, our solar-electric drivetrain integrates seamlessly with all onboard systems. Compared to fossil fuelled powertrains of motoryachts, electric powertrains have very few moving parts, resulting in minimal maintenance, maximum reliability and significantly lower running costs.

The ability to recharge your own batteries with the sun marks a new era of freedom. Depending on cruising speeds and weather conditions, a Silent has virtually unlimited range, enabling you to live a fully self-sufficient lifestyle on board. Unbound by the limitations of fossil fuels, you are free to explore the horizons.

The technology powering our yachts today has been pioneered by our founders almost three decades ago. Continuous upgrading and steady optimization of the entire system are some of the key reasons our in-house developed solar-electric drivetrain offers a comprehensive portfolio of assurances and warranties.

Powered by an advanced jet propulsion system, the fully electric Tender Series perfectly complements the experience on board of our catamarans. Following the same philosophy as our electric yachts, it was developed with a strong focus on being spacious, lightweight and efficient.

As a new breed of Silent, the Speed 28 combines futuristic design with blistering pace. Her high-performance drivetrain is supported by triple foils and embedded solar cells on the hardtop. Advanced hydrodynamics and latest AI management make for a stable ride which always remains comfortable.

Why Silent Yachts

A sensible approach to yachting which works in self-sufficient harmony with nature and creates a completely new experience on board.

PlanetSolar – The Largest Solar Boat in the World

PlanetSolar is the result of an envisioning by a few like-minded individuals of optimising solar energy into the maritime domain. A solar powered boat, the Planet Solar derives its name – Turanor Planet Solar – from the popular child fiction author JRR Tolkien’s reference to the sun’s brilliant force and energy.

PlanetSolar Details

The idea of a solar ship to operate in the marine waters was first thought of by Swiss engineer Raphael Domjan in the mid-2000s. Raphael’s conceiving of a solar powered boat was centred on the lines of the plots created by famous sci-fi author Jules Verne. But while the dream was quite strong, it started to actualise only in the late 2000s when like-minded collaborators entered into the venture and actually started the development stages for the largest solar boat ever.

Turanor was launched in the year 2010 following a construction process of more than one year. Engineers, scientists and researchers from across the globe have been involved in its creation making it a truly global venture aimed at tackling the major problem plaguing the marine sector. Soon after its launch, the vessel undertook her maiden navigation dream – to circumnavigate the world functioning only on solar energy.

Planet Solar Specifications

• The vessel has been designed on the lines of a yacht. After the completion of her maiden journey, the vessel will be utilised as a yacht aimed at offering opulence and comfort to patrons.
• The vessel has been mounted with solar voltaic cells which have been affixed to solar boards spread to an area over 5,000 square feet on the roof of the Planet Solar.
• The solar energy absorbed by these cells (38,000 cells) is in-turn stored in storing boxes which contain 12 lithium-ionised batteries.
• The vessel measures 31 metres lengthwise, 15 metres breadth wise and slightly six metres height wise. The vessel has a draft of around 1.5 metres.
• The vessel offers a maximum speed of 14 knots. In order to conserve the energy stored in the vessel, its speed however is regulated to an average of about four knots.

A total of 40 people can be easily accommodated in the boat. However for its maiden journey, the boat was equipped with a crew of only six people from various parts of the world. These six people include Raphael Domjan, the lead instigator of the solar boat concept.

As mentioned earlier, Turanor undertook its circumnavigating tour from Monaco about 18 months ago and has successfully completed its navigation. Its itinerary included the Galapagos, South America, Asia, Abu Dhabi and the oceanic waters in and around the Equator.

The largest solar boat is a revolution of its kind. With its inception, the PlanetSolar has realised the dreams of countless decades of using natural energy resources as viable channels of power supply.

An inside look at the world's largest solar-powered boat

Tûranor planetsolar, first boat to circle the globe with solar power, poses for photos in nyc.

By Dante D'Orazio

Share this story

Catamarans are fairly odd-looking boats, but earlier this week a special breed was docked at the North Cove Marina in Lower Manhattan. Alongside the typical handful of South Florida-based yachts that pop up here during the summer was an angular, flat-topped catamaran with a glistening blue deck called the MS Tûranor PlanetSolar. There's a reason why this boat stands out: last year it became the first ship to circumnavigate the globe on solar power alone . The 89,000 kg (nearly 100 ton) ship needs a massive solar array to capture enough energy to push itself through the ocean. An impressive 512 square meters (roughly 5,500 square feet) of photovoltaic cells, to be exact, charge the 8.5 tons of lithium-ion batteries that are stored in the ship's two hulls.

The Tûranor PlanetSolar ( tûranor means "power of the sun" in Elvish) is taking a break in New York from its current mission: a science expedition from Miami to Norway led by a University of Geneva-based research team. The climatologists, biologists, and physicists aboard the PlanetSolar are taking measurements of the Gulf Stream to better understand the relationship between the ocean and the atmosphere in an effort to gain new insight about climate change. In particular, they're studying and measuring currents, airborne particles called aerosols that reflect infrared heat and solar radiation, and the myriad natural phenomena that allow the Gulf Stream to function. Since the PlanetSolar is seaworthy and is emission-free, it allows the team to ensure that measurements aren't skewed by exhaust.

During the New York stopover press was invited aboard the PlanetSolar for a view of this boat that functions without any carbon emissions. The vessel might not be the most practical — it's big, it's slow, and it needs to avoid clouds — but it's a bold demonstration of how renewable resources might power ships of the future.

Solar-Powered Yachts Are Taking Over. Here’s Why That’s a Good Thing.

Diesel-powered engines are getting some healthy competition., michael verdon, michael verdon's most recent stories.

In 2005, Michael Köhler turned away from the diesel engines that had been powering his boats for 23 years and went instead with solar power, an idea that seemed laughable, given the technology’s limitations at the time. But after five years of testing and development, Köhler’s Solarwave 46 became the world’s first solar-powered yacht.

Since then, his Silent Yachts brand has become larger and ever-more luxurious, running bow-to-bow with traditional motoryachts. The new 80-foot tri-deck has a spacious salon and six staterooms, six-and-a-half-foot ceilings and unlimited cruising potential, since the lithium-ion batteries powering the 250 kw electric motors recharge on the go (and for free) courtesy of the yacht’s 1,227 square feet of solar panels. And the benefits extend beyond minimal emissions and engine vibration. “We have more living space than competitors,” Köhler says, “since electric motors require less space than diesel engines.”

Very different vessels are using electric propulsion to minimize noise and lower emissions, like Super Air’s Nautique GS22E.  Super Air

The solar niche is small but growing, with new entrants like Serenity Yachts and the BYD Group. These power yachts have cruising speeds of 8 knots and top speeds of up to 20 knots, though they’ll burn through battery packs quickly at that rate. Therein lies the design dilemma of battery-powered boats: Do builders prioritize range or velocity?

Correct Craft ’s new GS22E wakesurf boat found a way to twist battery limitations to its advantage. “We’ve designed the most energy-dense battery system for where a combustion engine typically goes,” says Sean Marrero, president of Watershed Innovation, which developed the GS22E’s Ingenity electric propulsion system. Tailored for hour-long sessions, owners can wakesurf in the morning, then recharge the battery so it’s ready after work. “It doesn’t run like a Tesla,” says Marrero, “but rather it mirrors the wakesurf experience with its stern dug into the water—minus the noise and emissions.” Other builders are rumored to have electric towboats in the works.

Feadship ‘s 273-foot Savannah.  Feadship

In the superyacht segment, Feadship director Henk de Vries would like to see every new yacht leaving his Dutch yard equipped with hybrid propulsion by 2025. De Vries is so serious about this mission that Feadship will absorb the extra cost over conventional propulsion, currently amounting to several million dollars, of those electric drives. So far, two boats have chosen hybrid power: the 273-foot Savannah , launched in 2015, and Feadship’s largest build, the 361-foot Anna, delivered two years ago. A third yacht launched that same year, the 287-foot Lonian , is also “heavily hybrid,” de Vries says.

“When we built Savannah , a hybrid with the [battery] equivalent of many Teslas in the engine room, we also invented the classification rules for these yachts,” says de Vries. “Even though the project was successful, the superyacht world was slow to adapt. I want to get to the point where one owner says to another, ‘Oh, your boat still burns fossil fuel?’ That will help create the mindset.”

• Serenity Yachts just released two models for solar-powered yachts.
• The boats were unveiled at the Miami International Boat Show in February. 
• The Serenity 64 costs $3.3 million, and the Serenity 74, which is in production, will cost $5.5 million.
• Visit Business Insider's homepage for more stories .

Nearly everything is getting a sustainable makeover, even luxury yachts, apparently. Grand Cayman-based Serenity Yachts just showed off two of their new designs for solar-powered yachts at the Miami International Boat show.

The Serenity 64 and Serenity 74 will go for $3.3 million and $5.5 million, respectively. So far, two of the 64 have been produced, while the 74 is still in production. The yachts are designed to maximize efficiency while maintaining a smooth ride, according to Serenity.

Look at the Serenity 64 here. 

Serenity Yachts unveiled two solar-powered luxury yachts at the Miami International Boat Show earlier in February.

The company has two of the Serenity 64 model, which it showed off in the water at the show.

The yacht is equipped with 65 square meters of solar panels.

They provide enough power for the yacht to cruise indefinitely at between four and six knots...

...while still powering all the amenities.

The Serenity 64 has electric and hybrid motors.

It has a cruising speed of five to six knots using electric power, or up to 16 knots using diesel.

The 64-foot boat can come in several different layouts.

Now, let's take a look inside.

This model has a combined galley and saloon on the main deck.

The cockpit table can fit six to ten people, with two more sofas that seat an extra eight people.

The lounge area in the saloon has a dining table that seats eight.

Furniture is made from wood veneers over a honeycomb interior.

As one potential interior option, the yacht can be built with an extra-large master cabin that spans the full hull.

In that configuration, there would also be two VIP cabins, each with their own bathroom, and one crew cabin.

Alternatively, the yacht could have four VIP cabins with en-suite bathrooms, plus a crew cabin.

Bathrooms each contain a sink, electric toilet, and separate shower.

The master bathroom is larger than the others.

It has a larger, king-sized shower, and an optional Jacuzzi.

All bathrooms have stone countertops and access to hot water, plus a rainfall shower.

Each bedroom has at least a double bed.

Cabins can also have additional storage under the bed and built into lockers.

Or, they can have extra lounge seating.

Each room also has a desk, plus additional floor storage.

The master even has a walk-in closet.

A large storage area is available as an alternative for the crew cabin.

The pantry includes a kitchen with cabinets for storage, a sink, and a cooktop.

The flybridge holds the engine controls and control panel.

The other controls are at the helm.

It's located on the upper level of the yacht.

It has three lounge seats, plus a sofa that transforms into a sunbed.

In case of bad weather, the retractable roof can close over the deck.

The upper deck can also be a great place to catch a sunset.

Right now, Serenity has two 64 models in the water, and the 74 model is in production.

It is also important to note that while there are solar panels for sailboats that you can fit on older models, those new boats have been specifically designed to maximize the use of renewable energy.

Most Luxurious + Most innovative solar system

The Eco 80 Sail Catamaran is one of the electric solar boats provided by Sunreef Yachts.

It features a unique “solar skin” that covers all composite structures on the boat, including hull sides, boom, mast, bimini, and superstructure. This green tech makes it possible to place solar panels where it wouldn’t normally be possible (like the hull and any other smaller but useful surface) and provide enough solar energy from every angle.

The boat is 80-feet long (24.38 meters) and includes electric motors that push it smoothly over the water without causing any vibrations or noise.

Besides being solar powered boat, the Eco 80 Sail Catamaran can also be powered by wind and hydropower. It is designed with a sail on its structure, allowing it to tap into wind power and supplement the solar.

The solar powered sailboat generates enough green power not only to propel the boat and keep it moving but also to charge the essential electric water appliances and other water-sport toys.

So far, the Sunreef Yachts Eco solar sailboats have earned a good reputation for being eco-friendly and sustainable. Besides, this solar powered catamaran takes its commitment to the environment a notch higher by using recycled materials , natural fibers, and non-toxic paints to create their boats.

It is no wonder that Sunreef Yachts have been winning environmental awards for so many years. This solar sailboat is one of the most remarkable boats you can ever invest in and it clearly shows the latest advancements in technology .

Prices: about $8 million USD

Where to buy : Sunreef Yachts .

• Relatively fast.
• Ideal for short vacations.
• The most affordable solar catamaran, starting at about $0.6 million USD.
• Much smaller than other options.
• Not recommended for long cruises.
• Basic looks and layout.

As its name suggests, the Soel Senses 48 is 48 feet long. It has a slender design and is lightweight , making it more economical than most other solar-powered boats.

The boat is designed with two sleeping berths that can accommodate two people each. It also includes a salon that can offer enough sleeping space for four people. 

Compared with most other solar yachts, the Soel Senses 48 has a much smaller size. Its size, adding to its sleek and innovative design, give it faster speed than other solar-powered boats.

It incorporates 12 solar panels installed on the roof ; all these panels generate a combined electrical power of up to 2.7 kWh. The electricity generated by the solar panels is then stored in two batteries which can be easily configured to hold a maximum solar power of 142 kWh.

Like other Soel Yachts, the Soel Senses 48 glides smoothly over water without causing any noise, rattles, or generating fumes.

It has average cruising speeds of 10 knots, even reaching top speeds of up to 18 knots. However, the solar catamaran cannot run at its top speed for long periods.

Both the interior and the exterior of the Soel Senses 48 have a sleek and modern design. Every single component of the solar catamaran has been designed carefully to make it as functional and comfortable as possible. Therefore, when you board on this boat, you can expect to experience one of the best sailing experiences of your life.

The diesel engine especially comes in handy when the users wish to achieve faster cruising.

The solar catamaran is a very spacious electric boat and provides plenty of living space. It is built with four luxurious cabins, with each cabin having its ensuite bathroom. And even though the Serenity 64 is smaller than the Serenity 74 model also built by Serenity, it still provided an elegant feel and a smooth sailing experience.

Solar Boats Pros and Cons

The sun is a powerful and free source of energy, making solar power an attractive option for those looking to power their yacht. Solar panels can be used to generate electricity to run the yacht’s lights, appliances, and even the engine. Solar power can also be used to heat water for showers and laundry. But, what are the pros and cons of solar catamarans?

Here’s a quick summary of the solar yachts’ advantages and disadvantages:

One of the main benefits of solar power is that it is renewable and environmentally friendly. Solar panels have no emissions and do not produce pollution. In principle, they also do not require fuel, making them very cost-effective in the long run. Solar power is also very reliable, as the sun is a constant source of energy.

There are a few disadvantages to solar power. Solar panels can be expensive to install, and while they require less maintenance, this can be quite costly, especially when it will come time to replace the batteries. Solar panels also need to be pointing directly at the sun to be effective, so they may not generate power on cloudy days or at night.

But there’s more, let’s see what some sailing experts are thinking about solar catamarans!

Sailing expert’s solar Boat review

Recently, one of the most popular sailing YouTube channels, Saliling La Vagabonde , published a very honest and interesting review of the solar powered yacht Silent 55. Here’s a summary of their experience:

• 7 Days onboard (6 nights)
• Travelled 145nm with an average speed of 7 knots
• Generator used for about 12h (in total)
• Fuel consumed: 208 liters

Here are some interesting observations they made:

• While cruising it may feel less stable than a standard sailing boat because it doesn’t have a sail to stabilize it when hitting the waves.
• For the Silent 55 it was possible to move at about 3 knots by using only the power generated by the solar panels (without using the batteries) on a sunny day. This means that if you are moving the solar yacht around quite frequently, you will end up using the generator quite a lot to produce the necessary power.
• When the batteries are out of power, the Silent yacht is using a (diesel) generator to supply the necessary power to keep the boat moving and to power the appliances.
• A great luxury yacht with all the comforts and going in the right direction for the future of the sector.
• Overall, the Silent Yacht is a great eco-friendly alternative to a power boat , while if you are thinking about cruising around the world, you would be probably better off going for a standard sailboat (or for some of the hybrid alternatives mentioned in this article, like the HH44).

Why are solar yachts all catamarans?

Solar yachts are all catamarans for 2 main reasons:

• Catamarans have a larger surface, which allows for placing more solar panels and also offers more room for the batteries onboard.
• Catamarans have efficient hulls for their size. This reduces their power consumption while moving.

This makes catamarans the ideal platform to build a solar-powered boat.

Modern solar electric boats are undoubtedly an eco-friendly choice in sea travel and a form of green tourism . Not only do these electric boats provide a smooth sailing experience, but they also reduce the release of emissions into the atmosphere, reducing the environmental impact and enhancing sustainability .

Luckily, given their size, solar catamarans can charge themselves (unlike electric cars ), so they can sail indefinitely without the need to stop for refueling.

If you are environmentally conscious and looking to get a boat that is more viable, desirable, and eco-friendly, you may consider investing in one of the solar yachts discussed in this article!

This is PlanetSolar, the largest solar-powered yacht in the world

Published on Mar 12, 2023 at 6:00PM (UTC+4)

• by Kate Bain

Last updated on Mar 13, 2023 at 5:16PM (UTC+4)

This is the largest solar-powered yacht in the world. 

Called the MS Turanor PlanetSolar, it has traveled more than 160,000 km (100,000 miles) across the world using only renewable energy. 

Impressive, yes, but the trip was not without issue.

According to Swiss explorer and PlanetSolar founder Raphael Domjan, this round-the-world trip required a lot of planning around pirates.

“When we imagined the PlanetSolar adventure in 2004, there wasn’t a problem with pirates in the Gulf of Aden,” he said. 

“But when it came time to cross this patch of water, there were almost 3,000 pirates operating in the area. 

“We had to cross the Gulf to complete our circumnavigation.

“Some of my partners said no, it’s too dangerous, and that we must put PlanetSolar on a cargo ship, but for us, that was out of the question. 

“We wanted to go around the world on our own boat using the energy we produced ourselves with our own solar panels.”

So, with marine commandos, armed riflemen on board, and barbed wire around the hull, they successfully crossed the Gulf of Aden. 

This didn’t stop pirate ships from approaching, but it did successfully stop them from attacking.

The idea for the ship was born back in 2004 and it was built in 2008. 

It was finished and launched that same year. 

It was in 2012 that PlanetSolar toured the globe and broke the world record for the longest voyage using solar energy. 

Traveling 160,000 km over 585 days, its crew took it to Venice, Paris, London, and New York. 

Every leg of the trip was 100 percent powered by solar energy. 

With a total of 500 solar panels covering the surface of the yacht, PlanetSolar looks unlike anything that’s come before it. 

The hundreds of solar panels provide 120 kW of energy, allowing the ship to reach a maximum speed of nine knots and a cruising speed of five. 

Without sunshine, the ship can also travel for up to three days.

The ship measures 31 meters long, 16 meters wide and 6.5 meters in height. 

But if you include the ‘flaps’, it measures 35 meters in length and an impressive 26 meters wide. 

The ship has now been donated to the Race for Water Foundation and is devoted to protecting the seas from plastic pollution.

Candela’s all-electric-powered hydrofoiling passenger ferry poised to transform global ferry transportation.

• Share to Facebook
• Share to Twitter
• Share to Linkedin

The all-electric-powered Candela P-12 ferry flies over the water on hydrofoils

I would never say “I told you so,” but…now that Candela , the world’s leading producer of all-electric-powered hydrofoiling boats, has just closed the largest funding round in the company's history, I might be bold enough to say…”I’m not surprised.”

That’s because I’ve been closely following the development of this wonderfully smart company’s hydrofoiling boats since I test flew a P-7 near their small and efficient shop in Stockholm in 2021. So, I’m really not surprised they just raised over $25 million to expand production of their game-changing P-12 ferry. And since yacht building powerhouse Groupe Beneteau is a key partner in the largest fundraising round Candela has ever completed it appears Candela’s brand of tech-controled hydrofoiling is about to go global.

“Our investment perfectly aligns with Groupe Beneteau‘s ecological transition objectives, scaling up innovative solutions for more sustainable boating and unparalleled experiences,” says Bruno Thivoyon, CEO of Groupe Beneteau, the world's largest boat manufacturer (15 factories, 9 brands, and more than 8,000 yachts built annually) with a total revenue of over $1.5 billion in 2023. “Candela’s technology, enabling significantly more efficient electric vessels, will transform waterborne transport into its next sustainable phase.”

300 billion crypto price crash suddenly accelerates as bitcoin ethereum and xrp traders brace for a fed shock, apple’s surprise update just made iphone more like samsung.

The new investment round will help to scale up production to meet demand for the recently launched Candela P-12, the world’s first electric hydrofoil ferry. The P-12 is the first fast and long-range electric ferry on the market. Its efficient hydrofoil technology cuts lifetime emissions by 97.5% compared to diesel vessels, while simultaneously allowing operators to save up to 50% in operating costs. Since it generates minimal wake, the P-12 has been granted exemptions from speed limits, as for example on its maiden route in Stockholm, where it from July will cut travel times in half compared to road transport and legacy diesel vessels.

And it’s pretty obvious Hasselskog and company are on the right track. According to some projections the market for electric vessels is expected to be worth $14.2 Billion USD in 2030.

“We’ve spent years developing the technological maturity, and now we’re fit for scaling to commercial vessels. As in any industry, the fastest-scaling company will dominate the market,” says Hasselskog.

The Candela P-8 and P-12 hardly make a ripple as they fly over the water on computer-controlled ... [+] hydrofoils

Other backers in the round include longtime investors EQT Ventures , Ocean Zero LLC , and Kan Dela AB. The new investment brings total funding since Candela’s inception to over $75 million.

“EQT Ventures has steadfastly backed Candela's vision to accelerate the shift towards fossil fuel-free lakes and oceans since 2021. The launch of Candela's P-12 vessels signifies a watershed moment in sustainable transport", says Lars Jörnow, Partner at EQT Ventures.

The only question is: when will we see a P-12 ferry here in the US?

Recharge at Sea: Solar Catamarans Harness Sun-Powered Serenity

Just as a residential solar system makes a house independent of an electricity grid, a marine solar panel makes a yacht independent of a fossil fuel powered generator. Catamarans boosted by solar power systems are increasingly in demand in today’s day and age for their increased energy efficiency and reduced environmental impact.

Here is everything you should know about solar catamarans from Sunreef Yachts Eco :

An Introduction to Solar Catamarans

Derived from natural sources, renewable energy is replenished at a far higher rate than consumed. Of these, solar energy is the most abundant renewable energy resource on Earth that may even be harnessed during cloudy weathers. Additionally, because sunlight remains omnipresent, powering a watercraft with solar energy is a fitting concept.

Before we continue exploring the subject of solar catamarans, let us focus on the architecture. The twin hull structure of catamarans translates into a large beam, which provides ample space for solar panels installation. To top it off, catamarans have a fairly shallow draft that produces little to no drag, making them exceptionally energy efficient .

Marine solar panels are currently gaining substantial popularity amongst catamaran designers and manufacturers as a medium of supplying clean energy via a reliable source. Sunreef Yachts Eco is a pioneer in solar catamarans as we believe that the incorporation of a solar power system into yachts births an environmentally friendly yachting solution with a significantly reduced carbon footprint.

The Benefits of Solar Catamarans

The ocean is home to the largest continuous ecosystems; unfortunately, it also remains the most sensitive. Millions of people across the globe indulge in recreational marina and boating activities leaving behind pollution in their wake.

Here are three ways in which solar catamarans rectify commonly occurring hazards for the greater good of the environment:

1. Fuel (oil or gasoline) spills and the discharge of combusted fuels from engines readily contaminates water surrounding the marinas. This aggravates toxicity levels in water, resulting in increased pollutant concentrations in aquatic organisms and sediments.

For illustration, coral reefs, which are a vital source of nitrogen and nutrients for marine food chains and provide shelter for over one million aquatic species, are nearing extinction due to water pollution. Installing solar panels would, without a doubt, decrease the dependency of all types of watercrafts on non-renewable energy sources, i.e., fossil fuels, for operations and increase energy efficiency.

2. Noise from moving gas-powered ships cuts straight to the sea floor and back. These acoustic vibrations transmitting end-to-end affect marine animals to a great extent. Research suggests that human-caused noises result in disrupted behaviours, increased stress, and impaired feeding in marine life, leading to injury and death. Solar catamarans are far quieter than their combustion-driven counterparts; thus, they maintain the oceanic silence vital for the marine life as it enables communication and continuous growth.

3. The elimination of fuels also makes solar yachts more affordable to run and maintain in the long haul. In comparison to fuel powered generators, solar catamarans produce electricity at a lower cost since solar panels obtain power via the sunlight, a renewable source of energy that is present in abundance. But even if your catamaran utilizes both fuel and solar power, you are still to enjoy significant savings on fuel.   

Why Power A Boat with Solar Panels   

Apart from the obvious environmental factors, solar panels fulfil an important criterion for the oceangoing voyagers who do not wish to be left stranded far from land with a dead battery: unlimited backup power.   

On a typical sailing day, there is ample sunlight to ensure the backup battery restores enough power to generate electricity that keeps motors, electrical systems, and onboard appliances running. An added benefit of solar panels is that they continue to generate power even when the catamaran is at a standstill. This energy is stored in batteries for later use.   

Furthermore, unlike gas powered generators, solar catamarans do not produce excessive heat, are quieter, and experience little to no vibrations. This allows boat trips to remain pleasant for sailors and vacationers.   

Sunreef Yachts combines luxury with sustainability to offer noiseless, vibration-free, and fume-free cruising experiences. Launched under the Sunreef Yachts Eco flag, our sailing and motor yachts are powered using inhouse engineered solar panels that are fully integrated within their composite structure for optimal results. However, an additional asset for sailing solar catamarans remains the ability to combine eco motoring with wind propulsion with the use of high-performance kites.   

The Mechanism of the Solar Power System   

Classification of solar panels   .

There are various kinds of solar panels available for marine boats: adjustable panels, standard panels, and high-energy thin-film panels. While some may argue that having a portable solar panel makes it easier to relocate to where the sun shines the brightest, permanently mounted panels remain ready to go throughout the day.

Despite their long life, standard panels often fail to find a place in the marine industry as they compromise the space availability onboard. Hence, high-energy thin-film panels emerge as winners due to their ability of being permanently embedded on the solar catamaran’s bodywork without restricting living space.

The research and development team at Sunreef Yachts Eco developed the industry’s first composite integrated photovoltaic technology to produce highly efficient, shock resistant, flexible, and ultra-thin solar panels. This in-house engineered solar power system was recognized as a winner of the German Design Award 2022 in the category of Excellent Product Design: Eco Design .

Each solar panel consists of photovoltaic cells, compromising of a positive and negative layer for creating an electrical field. These are made of singly-crystal silicon, a semiconductor that absorbs the radiations of the sun to produce electrical power via the photovoltaic effect. For better understanding: the photovoltaic effect is the process of converting photons (a particle of light) to voltage.

Technical Specifications of Solar Panels

While the average solar panels’ weight lies between 8 to 15 kilograms per square meter, Sunreef Yachts Eco’s solar cells have a thickness below one millimetre and weigh only 1.8 kilograms per square meter. This makes Sunreef Yachts Eco the lightest marine solar power system producer in the solar catamaran market.

Each of the solar cells administered into the Sunreef solar catamarans are ISO 9001:2015 certified and offer a peak performance of ±24 percent, this is 25 to 30 percent more power compared to conventional cells. Despite this, these solar cells do not heat up excessively when receiving sunlight.

Integration Into the Solar Catamarans Structure

The orientation of the sun should be as such as that it hits the solar panels at a 90° angle for best performance. However, with the Earth rotating around its axis to produce a 24-hour day, it is non-viable to ensure the perfect angle throughout the day.

What is more is that the amount of energy produced may also differ depending on external factors, such as a building preventing direct sunlight from hitting the solar panels or light experiencing diffraction from the waterbody before contact. For this reason, it is best to invest in high-efficiency solar cells that generate maximum energy even from limited number of active panels.

Sunreef Yachts Eco makes the most of its solar catamarans’ space availability by spreading its “solar skin” across the hulls, mast, superstructure, bow terrace and bimini roof. Due to this arrangement, the solar panels receive ample sunlight at desired angles from early morning to late afternoon.

At the same time, light rays bouncing off the surface of water to the solar panels, in a process called reflection, also helps generate electricity. These superior performance solar panels possess great strength and durability to survive adverse conditions, year after year.

Generation of Electricity on Solar Catamarans

The crystals in marine solar cells are treated to enable the movement of electrons to generate an electric current. These silicon electrons activate only when in direct contact with sunrays. Instantaneously they start producing direct current (or DC) charges, which is captured by wires and stored in the batteries as energy.

At this point, a charge controller is employed as a regulator for the energy to transfer from the solar panels to the battery. It not only manages the energy load received by the battery, but also prolongs the battery life and performance by ensuring the battery is not overcharged or overloaded. Solar catamarans deploy multiple charge controllers depending on the energy produced.

While the current may be supplied directly to support the electrical demands of the catamaran, if the appliances demand alternating current (or AC), an inverter is added to the cycle to convert the DC to AC first.

Solar Catamarans in Action

But how much energy is enough energy? Working out a catamarans’ energy requirements requires summing up the energy consumed by each device onboard in watt-hours. For better understanding: energy is power accumulated over time, so if power is calculated in watts, energy is watt-hours.

Hence, the first step of installing solar panels dictates an extensive energy assessment of the watercraft. This requires checking the labels of every individual appliance onboard for its typical amp hours and volts used, be it the fridge, fan, or lightbulb. A battery monitor can also help measure energy consumed more accurately.

Depending on the size of the catamaran and the energy consumed, the solar panels size and wattage of power can be precisely determined. Multiple solar panels may be wired together to form a solar array for maximum energy generation. Aiming to fulfil the power needs of your catamaran with solar panels allows you to enjoy a quiet, peaceful anchorage.

Overcoming The Challenges of Solar Catamarans

While yacht solar panels resolve the problem for keeping the batteries topped up without running the generator, solar power systems are faced with challenges of their own. For starters, the harsh weather incurred at sea and saltwater splashing on or immersing the panels accounts for much damage.

However, technological advancements have enabled solar panels to withstand most of these environmental adversities. To illustrate, the installation and electronics linked with solar power systems have now become more resistant to short circuits and corrosion.

Sunreef Yachts Eco employs a unique photovoltaic integration technique in solar catamarans to give the panels extreme resistance to shock and abrasion. Even if the cell eventually cracks, the solid metal foundation remains intact to maintain a high-power output. Furthermore, these solar panels experience no light-induced degradation, no temperature coefficient, and favourable low-light and broad spectral response.

Likewise, the constrains of surface area for marine solar PVs have been addressed with the ability to manufacture customized solar panels. For instance, Sunreef Yachts Eco uses the lightest solar cells in the industry which offer unparalleled flexibility for placement on rounded surfaces of the solar catamaran while others break under pressure. Here solar panels are integrated vertically (on hull sides, flybridge sides, and mast) and horizontally (on front flybridge and bimini) to maximize energy generation.

While the Sunreef Yachts Eco’s solar panel system has a protracted life expectancy, any panels sustaining damage, due to adverse conditions at sea or other geographical circumstances, can easily be replaced. However, it is proven repeatedly that their performance remains unaltered over extended periods of time.

Efficiency of Solar Catamarans Vs. Diesel Yachts

Solar panels make for an ideal energy provider as they ensure the batteries always have power. This makes solar catamarans more self-sustainable and cost efficient to run in comparison to gas-powered ones. Additionally, fewer moving parts in solar catamarans call for significantly lesser maintenance in comparison to diesel yachts.

Boats of all shapes, sizes, and types (sail or motor) can be powered via solar energy to run all onboard appliances on battery. Apart from fulfilling the watercrafts’ day to day electrical usage, utilizing a renewable source of energy extends the durability and reliability of the catamaran.

But most importantly, a solar powered yacht compared to a standard diesel yacht has a significantly reduced carbon footprint. Ideally, with the use of solar power generation on catamarans, you would save 108.5kg of CO2 emissions per day or 39.6 metric tonnes annually.

Why Invest in A Solar Catamaran?

The wind in your hair, the sun on your face, and the sweet smell of the sea are one of the many joys of sailing. However, as an ocean enthusiast, it is crucial to calculate your impact on the environment. On average, the Sunreef Yachts Eco’s solar catamarans account for substantial electricity generation of up to 30 kWh, promoting a positive green footprint.

Today, solar catamarans are trending among yacht owners and shipbuilders as a clean medium to increase energy efficiency and reduce carbon emissions. Additionally, staying true to its legacy of yacht innovation and evolution, Sunreef Yachts Eco continues to work on advancements to its solar panels for improved performance, efficiency, and durability.

Evaluating the Sunreef Yachts Eco Solar Catamarans

Using advanced technology, Sunreef Yachts Eco has engineered ultra-thin, flexible solar panels with the best performance on the market. They are seven times lighter than the average solar power system, enabling them to be fully integrated into the composite structures, including curved surfaces.

The more surface area covered, the more electricity generated. The 80 Sunreef Power incorporates 200 square meters of solar panels (weighing about 360 kilograms) that deliver an astounding 40 kilowatts peak per hour. This setup alone produces solar energy equalling to two generators weighing 800 kilograms altogether.

Hence proven that Sunreef Yachts Eco optimized marine solar panel system outperforms a diesel generator both by weight and performance. Additionally, at reduced speeds, the Sunreef 80 Eco remains fully autonomous, running solely on solar power.

In light of sustainable yachting, Sunreef Yachts Eco has committed to launch over 40 models of its solar catamarans by the end of 2024; this includes a wide selection of sailing yachts, power yachts, and superyachts. Furthermore, Sunreef Yachts has begun commissioning a new range of technologically advanced hybrid ecospeeders, called the Sunreef ULTIMA , that would further extend their solar catamarans line up.

Future Innovations in Solar Catamarans

Despite the distinctive competency of Sunreef Yachts Eco in solar catamarans, the journey of innovation does not come to a halt. To further reduce our carbon footprint, we are undergoing ground-breaking research to redirect excess heat secured from direct sunlight on solar panels to the boilers of our solar catamarans.

Furthermore, Sunreef Yachts Eco is currently developing a concept of an all-new 90 feet sustainable sailing superyacht , called ‘The Zero Cat’ . Apart from sporting a solar power system, this catamaran will use a zero-emission generator to convert methanol to clean hydrogen for unlimited autonomy and greater self-sufficiency.

PMG Shipyard launches the Silent-Yachts 62, the World’s Largest Solar Powered Yacht

RAYONG, Thailand – Imagine sailing across the ocean on a luxurious catamaran that runs on clean, renewable energy. No noise, no fumes, no fuel costs. Just the sun, the wind, and the waves. Sounds like a dream, right?

Well, for some lucky yacht owners, this dream is already a reality. Thanks to PMG Shipyard, a leading yacht builder based in Thailand, solar powered catamarans are no longer a fantasy, but a feasible option for anyone who loves the sea and cares about the environment.

PMG Shipyard has been producing high-quality yachts since 2004, with a focus on innovation, customization, and sustainability. The yard has a strong European presence in management and key technical positions, as well as world-renowned members of the advisory board. PMG Shipyard has earned a reputation for excellence in craftmanship, design, and service.

One of the most remarkable achievements of PMG Shipyard is the partnership with Austrian based Silent-Yachts, a pioneer in solar powered yachting. Together, they have launched several models of Silent-Yachts catamarans, which are fully equipped with solar panels, electric motors, and batteries. These yachts can cruise for hours without using any fossil fuels, and can even generate surplus energy that can be used for appliances, entertainment, and air conditioning.

The latest addition to the Silent-Yachts fleet is the Silent-Yachts 62, a 62-foot luxury catamaran that offers four spacious double cabins, each with its own bathroom. The main deck features a large salon and a kitchen that rivals most apartments, with plenty of refrigerator and freezer capacity, dishwasher, washing machine, and more. The yacht also has a diesel generator for backup power, in case of emergencies or prolonged cloudy weather.

On Tuesday, November 28, 2023, PMG Shipyard launched the fifth Silent-Yachts from its shipyard in Rayong, Thailand. The yacht will soon be on its way to its owner in North America, who will enjoy the benefits of solar powered yachting. This Silent-Yachts 62 is the last Silent-Yachts from PMG Shipyard, but the yard offers other catamarans of similar size with electric propulsion or conventional propulsion with solar power for utilities.

Among the yachts currently in production at PMG Shipyard is one that is solar powered, fully electric. Like the Silent-Yachts 62, it will rely solely on the sun and the batteries for power. This will make it even more eco-friendly, efficient, and comfortable. Also in production are a couple of PMG’s “standard” models, the solar assisted Cora 48 with diesel engines. These yachts will have solar panels for domestic appliances, which will reduce the fuel consumption and emissions, while still providing enough power for long-distance cruising.

PMG Shipyard is proud to be at the forefront of solar powered yachting, and to contribute to a sustainable, clean-energy future. The yard is always looking for new ways to improve its products and services, and to meet the needs and expectations of its customers. If you are interested in owning a solar powered catamaran, or any other type of yacht, PMG Shipyard would be happy to discuss your future boat with you.

PMG Shipyard: The Future of Solar Powered Yachting

Solar power is not only a solution for land-based energy needs, but also for marine transportation. More and more yacht owners are opting for solar powered catamarans, which offer a range of benefits, such as lower emissions, lower costs, lower noise, and higher comfort. One of the leading companies in this field is PMG Shipyard, a Thai-based yacht builder with Swiss management and expertise.

PMG Shipyard was founded in 2004 by Philippe Guénat, a passionate yachtsman and hotelier who wanted to combine his love for the sea and his interest in solar technology. He envisioned a future where yachts could run on clean and renewable energy, without compromising on performance or luxury. He assembled a team of professionals from various backgrounds, including engineering, design, and hospitality, to make his vision a reality.

PMG Shipyard also has a distinguished technical advisory board, composed of experts from different fields, who provide guidance and support to the company. The members of the board are:

Back in Switzerland, he has been heading a group of hotels. Now Philippe is based in Thailand and brings all his expertise to PMG Shipyard. As a member of a family involved in a shipyard on Lake Geneva, Philippe quite naturally decided to devote his energy and competence to PMG Shipyard.
