Sunreef Power Eco Is A Think-Different Catamaran

• By Kim Kavin
• February 14, 2024

Any yacht that’s built with a “solar skin” is bound to attract owners who have at least a few thoughts about the environment. Such is the case with Sunreef’s Power Eco series of catamarans. Formula 1 driver Fernando Alonso recently took delivery of a 60 Power Eco, saying that sustainability considerations were fundamental to his vessel choice. The owner of the first 80 Power Eco , christened Sól , built the yacht entirely cruelty-free, including far more than avoiding animal-derived fabrics such as leather.

As just one example, there’s a composting machine on board Sól . It lets the chefs reduce trash by turning scraps into fertilizer for island farmers, who, in exchange, provide the yacht with locally grown microgreens. “This is definitely different,” says chef Sara Nelson. “I don’t know any other boat doing these things to the level that we’re doing them.”

The captain of Sól thinks about sustainability right down to the crew’s polishing tools for the hull. “You need woolies, but I had to go to the manufacturer to see if it was real wool or not,” Capt. Jack Gorman says. “These are synthetic wool. That’s what we’re going for. Everything down to the bottom paint is cruelty-free. Ablative bottom paints, if you put 20 gallons of that on your yacht, it sloughs off into the environment, and it’s bad for the reefs. We’re using a silicon base without biocides.”

The 80’s two rotating chefs trained in plant-based cooking with celebrity chef Matthew Kenney. Aboard Sól , they will prepare any type of food that guests prefer, but they are ready for charter clients who want all-vegan menus.

“Most people are reducers,” the 80’s owner says. “A small percentage of the world is vegan, but the majority of people have been looking for plant-based options—not necessarily three meals a day, but they will choose a plant-based dinner some percentage of their evenings.” Aboard Sól , he adds, “it’s delicious, exquisite, high-quality plant-based options.”

As their name implies, the Sunreef Power Eco yachts also have electric power. Sunreef has been adding energy-saving air-conditioning systems, along with custom battery banks that are lighter—and, therefore, can be bigger—than the types of batteries some other builders are testing.

The result is the kind of cruising and charter experience that appeals to people who are eager to make an eco-friendly turn. As Alonso puts it, “long, fume-free and quiet cruises let you enjoy the seas on a whole new level. This yacht has some amazing technology that cannot be found anywhere else.”

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.

The sleek vessel stretches 140 feet  Sunreef

Speaking of power, the cat will be equipped with two 200 kW electric motors that promise a top speed of 14 knots and cruising speed of 11 knots. In addition, the cat comes with a set of high-performance sails that can harness additional power from the wind. What’s more, Sunreef says she’ll be fitted with an advanced hydro-generation system that keeps producing green power while under sail.

Eco-friendly touches can be found onboard, too. The catamaran’s light-filled interior, which offers space for up to 12 guests, will feature a curated selection of ethically sourced woods, natural fabrics and sustainable materials. The smart power and water management systems, meanwhile, promise to reduce overall energy consumption.

The ship has multiple terraces and lounge areas.  Sunreef

It’s outdoors that the vessel really shines, though. To the aft, there is a large hydraulic platform and two fold-out bulwark terraces that can be lowered to create a vast walkaround beach club. Sunreef says this space can be completely customized with a bar, fitness area or storage room for water toys, for example.

Elsewhere, the generous flybridge comes fitted with a spa pool flanked by sunpads, a bar for alfresco cocktails and an outdoor movie theater, while the bow sports another spa pool and more lounge seating. There’s also a hidden aft garage that cleverly conceals two tenders, an inflatable catamaran and two tenders.

Of course, the best part is the fact that you can sail all day long, all year round.

Video: First look at 140m superyacht SOLARIS totally unveiled

• Share this on Facebook
• Share this on X
• Share via Email

By Nina Done   24 March 2021

New video footage of the elegant 140m  mega yacht SOLARIS reveals more of her spectacular design features following her official launch from the Lloyd Werft shipyard in February — which was slightly hampered by a case of heavy fog. She has now left the German shipyard to undergo sea trials before her expected delivery this summer.

Penned by Australian designer Marc Newson in his debut superyacht project, SOLARIS is the culmination of four years under construction where the project has been mired in secrecy. Her preparation for sea trials comes after much excitement that's rippled through the yachting industry.

The video footage reveals an aft glass-bottomed pool, 2 beach clubs, an expansive swim platform and pronounced wing stations on either side offering enhanced visibility for the captain whilst maneuvering. 

In addition, floor-to-ceiling windows will allow plenty of natural light throughout her interiors, with exterior glass railings offering unique views of her surroundings whilst enjoying the alfresco entertainment.

18 megawatts of combined propulsion...will propel SOLARIS at speeds unheard of for superyachts of this size.

SOLARIS boasts a whopping 8 decks, helipad, plus hangar and generous beach club aft. She also has a tender garage equipped with a crane for launching tenders, cleverly designed to be hidden away from the main guest areas.

Her elegant appearance is accentuated by the large arch that wraps across the beam midships, providing a dramatic contrast with the sleek lines of her pale grey hull and crisp white superstructure.

Enhanced power

18 megawatts of combined propulsion delivered through two state of the art Azipods managed by an ABB Engine Management System will propel SOLARIS at speeds unheard of for superyachts of this size.

Availability for yacht charter?

SOLARIS is being built for an experienced owner and it is believed that she will not be offered for charter by those in the industry.  If you would like to visit areas outside of the usual cruising grounds of the Mediterranean and Caribbean then please take a look our selection of  expedition yachts for charter  that are currently available.

Solar Powered Yachts

Solar panels are a fundamental element of today’s quest for responsible energy generation. Used in households, commercial facilities, and power stations across the globe, they are also a vital source of energy for solar powered yachts. With significant progress made over the last years, photovoltaic technology has emerged as the natural energy source with the most exciting growth potential.

Thanks to photovoltaic cells, solar panels absorb sun radiation to generate direct current (DC). When sunlight reaches a solar cell, it causes silicon electrons to move. This motion will start the flow of electricity that is captured by wires and directed to an inverter. Inverter technology is then used to convert it to alternating current (AC) ready to power household appliances.

The solar power systems on solar powered yachts usually consist of solar panels, batteries, charge controllers and inverters. While batteries store the energy obtained from the solar panels, charge controllers prevent batteries from overcharging. Solar catamarans with house appliances on board will usually need to convert the DC energy into AC with the help of an inverter.

Sunreef Yachts produces solar panels in-house and uses a new (patent-pending) technology to integrate them within structural components. The panels are made of the industry’s most efficient cells with a peak performance of 24%.

Thanks to the solar cells’ outstanding flexibility, Sunreef Yachts’ solar panels can be mounted on any surface of the solar powered yacht. As a result, they are integrated with various areas on board, such as hull sides, mast, superstructure, bimini roof or bow terrace to maximize energy generation.

With a thickness below 1mm and weighing around 1,8 kg per square meter (average solar panels will weigh between 8 and 15 kg per square meter), they are one of the lightest solar power systems in the world. In addition, tests have proven that thanks to their advanced integration technique, Sunreef Yachts solar panels have a very high resistance to shock and abrasion. This allows them to be used on any surface, including hull sides.

Sunreef shows off gorgeous 80-foot solar electric luxury yacht ahead of US debut this month

Eco-responsible shipbuilder Sunreef Yachts had given the public its first glimpse of its new 80-foot solar electric yacht before it makes it US debut in Fort Lauderdale, Florida later this month. The 80 Sunreef Power Eco is a fully-electric luxury catamaran that could very well be one of the most advanced solar electric yachts built to date.

Sunreef Yachts was established in 2002 in Gdansk, Poland where its shipyard and office still operates in addition to a presence in the the UAE. A year into its existence, the company was touting the launch of the world’s first 74-foot luxury oceangoing catamaran with a flybridge and has been innovating ever since.

Today over 140 Sunreef Yachts are sailing waters across the globe, and the shipbuilders clientele includes Tennis great Rafael Nadal , plus F1 champions Fernando Alonso and Nico Rosberg. As the company looks to delve further into electrification, its latest vessel – the 80 Sunreef Power Eco has already garnered a German Design Award 2023.

Its touting some truly unique solar technology you can see below, and if you happen to be in the Miami/Fort Lauderdale area this month, you can check out Sunreef’s solar electric yacht in person.

Top comment by dan b.

To be clear, I'm not a boater and not fond of being on water that much. In my younger days, I did have a couple boats and was on the Mississippi quite a lot as well as a larger lake in NW IL. The thing that I recall not so fondly was the smells and fuels, putting fuel in them, the spills in the water, the nasty exhaust fumes and film in/on the water, etc. That's always bothered me and I feel that the boating industry may be one of the dirtiest as for pollution along with motorcycles. The fact that boats spend so much time baking in the sun makes them totally great for solar.

So I'm happy and grateful for the fact that boats and motorcycles seem to be moving well into the EV power and using renewable energy as well. It gives me hope for the future where people can still enjoy recreational activities while greatly reducing emissions.

In addition to the new images of 80 Sunreef Power Eco above, we’ve learned that its makers are already declaring the solar yacht “world’s most advanced electric luxury catamaran,” due in large part to is emission-free in-house technology.

The 80-foot vessel is propelled by two 360 kW motors, powered by a massive 990 kWh battery bank. Sunreef says these custom-engineered banks offer an energy density less than 5.2 kg per kWh, nearly 30% lighter than the typical systems most commonly used in the yachting world today.

What may be most impressive about this electric yacht is Sunreef’s 36 kWp composite-integrated solar panels, which have been seamless placed along the catamaran’s hulls, bimini roof, and superstructure. Sunreef describes the technology as a “solar skin” around the yacht.

The interior features 4 luxury cabins and customizable layout to comfortably sleep eight guests. unfortunately, that’s all Sunreef is sharing about the 80 Power Eco at the moment, but the public can learn more at the Fort Lauderdale International Boat Show , taking place October 25-29. It’s there that this beautiful Sunreef yacht will make its US debut. If you happen to go and see her up close, please send me pictures. If you buy one… please invite aboard. TYSM.

If you are an advocate of sustainable yachting or sustainable tourism and are looking to buy an eco-friendly boat that doesn’t rely on fossil fuels , then you would do well to consider getting a solar catamaran. In this article, I will go through the pros and cons of 10 of the best solar yachts and superyachts that you can buy in 2023 and 2024!

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 .

• Larger surface covered with solar panels, that are installed also along the hull, and in other unusual areas.
• The batteries are 30% lighter than normal
• Unlimited cruising range.
• It runs silently and does not cause pollution.
• It has also traditional sails, so it can cruise also when it is not sunny without relying on batteries.
• Luxury, superb quality and finishing
• Great helm position.
• The solar catamaran is very costly (going for $8 million USD or more).
• The solar panels installed on the sides of the catamaran may not be appealing to the eye of all people.

Silent Yachts – Silent 80 Tri-Deck Solar Catamaran

Best pure electric

The Silent 80 Tri-Deck Solar yacht is popular for the large amount of space it offers.

This solar catamaran by Silent Yachts features three large decks that can be easily customized to fit the owner’s preferences and needs. The topmost deck can either be open or enclosed.

This solar powered yacht offers 4 to 6 cabins that are customizable, regardless of whether the deck remains open or enclosed. Besides, the top deck provides additional living space and can be used as a luxury master suite that opens onto a private space outdoors.

Where to buy : Silent Yachts .

• Purely electric propulsion that can be helped by the kite sail.
• The finishing, while being of high standards, doesn’t seem to be at the level of other options in its category.
• Quite costly, with prices starting at about $6 million USD.
• If going for a long cruise during cloudy days you may need to run the generator to keep going.
• The kite sail helps to give some propulsion using wind, but it is less effective than traditional sails.
• The absence of a traditional sail may make the boat a bit less stable, compromising a bit of the comfort while cruising.

Best for world cruising

HH Catamarans is a small boutique boat builder designing some of the most impressive solar boats for cruising, with one of their latest creations being the HH44.

The HH44 is a groundbreaking new boat that is designed to be eco-friendly and efficient.

The boat has a large battery bank that can be charged by solar panels, and also has two electric motors that can be used for electric propulsion up to 7 knots for up to 2h.

• The diesel engines can be used both for propulsion and as electric generators.
• Possibility to use the propellers to recharge the battery while the boat is sailing. Kind of like using hydropower to charge your solar batteries , pretty cool!

The HH44 is also a performance catamaran thanks to its C-shaped §daggerboards. Daggerboards are an essential component of many sailing vessels, providing both vertical lift and increased upwind sailing performance.

This solar powered yacht features up to 4 double cabins and 2 heads . Not bad for this world-cruising vessel!

If instead, you are looking for a larger boat, HH Catamarans also have other models up to 88ft.

This solar catamaran was also the preferred choice of Gone with the Wynns , a popular cruising YouTube channel. Here’s their announcement video:

It is usually designed with up to 6 cabins , with each cabin offering every basic amenity you need to have a luxurious stay on the yacht. In fact, the electric solar boat is equipped with everything you need to allow you to live on board permanently!

As someone who loves spending time on the water, I was really excited to learn about the Sunreef 43M Eco: a superyacht that is both eco-friendly and luxurious.

I was especially impressed by the solar power system, which is built into the composite structures of the yacht, and the large hydraulic platform which creates a vast walkaround beach club.

The interior of the solar superyacht is just as impressive as the exterior, with a variety of sustainably-sourced materials and fabrics used throughout as well as energy-saving air-conditioning. The Sunreef 43M Eco can welcome up to 12 guests in the most luxurious conditions.

Silent Yachts – Silent 120 Explorer

Here’s another incredible solar super-yacht by Silent Yachts. The Silent 120 Explorer is a truly unique yacht, designed to explore the world in style and comfort.

Powered by solar energy, this solar catamaran is perfect for those who want to enjoy the beauty of the open seas without worrying about the impact on the environment.

If you’re looking for an electric yacht that is both luxurious and eco-friendly, the 100 Sunreef Power Eco is certainly a great option for you if you can afford it!

The most affordable $

The Aquanima 40 catamaran is entirely powered by solar energy. It features creative adaptations and unique innovations that make it eco-friendlier and more economical boat than other solar-powered catamarans. For example, the solar panels installed on the electric catamaran are built in such a way that they can sell any excess solar energy back to shore stations when connected.

The exterior of the Aquanima 40 has an elegant design. Also, the interior is not only aesthetically pleasing, but also very clean and modern.

The boat is designed with 2 single cabins for the crew and 2 double cabins for guests.

Indeed, this solar boat by Azura Marine is one of the most economical and cost-effective options you can go for when buying a solar catamaran.

• 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 Serenity 64 Yacht features a diesel engine. It is a hybrid solar boat, which means that it can run on either solar power or on diesel.

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!

Atutu’s solar field technicians are installing a solar array on top of a hospital in a town in ... [+] Northern Kachin, Myanmar in May 2024.

An engineer who left the south-east Asian country of Myanmar as a child is now spear-heading efforts to provide solar power to hospitals in remote areas there.

According to a 2023 World Bank report , there are over four million households without access to electricity in Myanmar, which is embroiled in the midst of civil conflict .

Lin Thu Hein , co-founder and executive director of a non-profit called Atutu, says the team is working to bring solar energy access to rural healthcare facilities in northern Myanmar , having started out bringing solar energy to indigenous communities and conflict-affected communities in Kachin State.

"After working in displaced communities and powering schools, many of our communities encouraged us to look into healthcare centers, since the lack of grid energy and rising fuel prices were causing resource strain in the healthcare industry; many hospitals and clinics operate using diesel generators," he says, "Patients and healthcare staff have had to pay out of pocket to cover the cost of diesel during their hospital stay due to budget shortages."

Hein explains this led the team to pilot a project at a local hospital in northern Kachin state in Myanmar, in order to validate the feasibility and benefits of a solar microgrid in a healthcare setting.

"After nearly 3 months of operation, we saw that the solar power has served as the primary source of power for the hospital since installation, leaving the generators as backup emergency power," he says, adding that the logistics challenges posed from ongoing armed conflicts means access to diesel has been sparse or exorbitantly costly.

"This project has environmental, social, and financial benefits to the communities," he says, "If we’re able to make technology work with all the challenges in Myanmar, we are most likely to make it work in other communities too."

Based on the success of the pilot project, Hein and his collaborators entered into a partnership with a capital planning software start-up called ACTUAL to bring solar energy to the hospitals and other healthcare centers that are under-resourced in rural areas of Myanmar.

"We are building a project portfolio of microgrids to over 300 off-grid healthcare facilities, and support their transition to solar energy from diesel generators," Thein says.

Karthik Balakrishnan , president and co-Founder of ACTUAL says that they've partnered with Atutu to tackle the complex energy challenges in Myanmar

"Our AI-powered platform will help identify and structure financially viable renewable energy projects that can make a real difference in people’s lives,” Balakrishnan says.

Lin Thu Hein, Atutu’s executive director, is assembling a prototype for a new product that will be ... [+] used in future projects at a warehouse in California in August 2024.

From Kachin To Bay Area and Back

Hein grew up in a small rural town in Kachin State, Northern Myanmar called Tanai (a.k.a. Danai), but migrated with his family to San Francisco, California, USA at the age of 13.

"My family received two hours of electricity per week when I was growing up in Kachin; my upbringing in a rural off-grid community exposed me to challenges, experiences, and localized knowledge that can not be taught or researched," he says, "My childhood in Myanmar and my experience as an immigrant has shaped my ambitions to give back to marginalized communities like mine who are often forgotten or left behind."

Hein says that this fascination with energy and first hand experience of the energy gap drove him to pursue a degree in electrical engineering. After working with a local nonprofit with the goal of bringing solar lights to a small community in the Philippines during his college years, Hein joined a Berkeley based startup New Sun Road after graduation, working in hardware, cellular connectivity, and IOT devices.

"In the fall of 2021, I received a fellowship from Echoing Green, which equipped me with resources and funding to work full time for Atutu, bringing energy access to offgrid communities in Myanmar," he says.

Hein explains that when he meets leaders from other indigenous communities or communities from the Global South, there’s a feeling of solidarity and he can see the care, compassion, and determination they bring to their work to improve their communities.

"Without the voice, representation, and participation of leaders from the Global South with lived experience, we are likely to deploy ineffective interventions in our fight to make the world a more just place," he says, "I have received a plethora of helpful guidance and mentorship from other leaders from the global South who are working to improve their own communities.

Bamboo Know-How From Myanmar

A different group of engineers are now using of bamboo construction know-how from prefabricated housing in Myanmar to build a much large structure in Madagascar.

Raphaël Ascoli , founder of Yangon-based architecture design studio Blue Temple explains that he was working in Japan as an architect for a corporate design firm, before quitting and moving to Myanmar seven years ago to specialize in small-diameter bamboo construction and scaling-up the production of prefabricated bamboo low-cost housing units for internally displaced people (IDP) and informal settlements.

"Small diameter bamboo is abundant on the local market; this species was never used in construction because of its slenderness, but bundled in large groups, it can become a strong structural element," he says.

Ascoli explained that after having experimented with this technique for a couple of years, his team was building houses for the price of a smartphone, about 1000 dollars.

"Today we have built over 14 housing units in IDP camps and informal settlements such as an orphanage, a preschool, a community center, and houses," he says, adding that bamboo can change the carbon footprint of the construction industry.

New nanogenerators achieve 140-fold power density gain, could rival solar cells

T hanks to new nanotechnology developed at the University of Surrey, your early morning run could soon help harvest enough electricity to power your wearable devices.  

Surrey’s Advanced Technology Institute (ATI) has developed highly energy-efficient, flexible nanogenerators that demonstrate a 140-fold increase in power density compared to conventional nanogenerators. 

ATI researchers believe that this development could lead to nano-devices that are as efficient as today’s solar cells. 

Energy conversion

Surrey’s devices can convert small amounts of everyday mechanical energy, like motion, into a significantly higher electrical power, similar to how an amplifier boosts sound in an electronic system. 

For instance, if a traditional nanogenerator produces ten milliwatts of power, this new technology could increase that output to over 1,000 milliwatts, making it suitable for energy harvesting in various everyday applications. 

ATI’s nanogenerator works like a relay team – instead of one electrode (the runner) passing energy (charge) by itself. 

Each runner collects a baton (charge), adds more, and then passes all batons to the next runner, boosting the overall energy collected in a process called the charge regeneration effect. 

“The dream of nanogenerators is to capture and use energy from everyday movements, like your morning run, mechanical vibrations, ocean waves, or opening a door. The key innovation with our nanogenerator is that we’ve fine-tuned the technology with 34 tiny energy collectors using a laser technique that can scale up for manufacture to increase energy efficiency further,” said Md Delowar Hussain, a postgraduate research student at ATI.

He added that what’s exciting is that our little device with high energy harvesting density could one day rival the power of solar panels and be used to run anything from self-powered sensors to smart home systems that run without ever needing a battery change.

Turning energy into electricity

The device is a triboelectric nanogenerator (TENG) that can capture and turn the energy from simple, everyday movements into electricity. 

They use materials that become electrically charged when they come into contact and then separate – similar to when you rub a balloon on your hair, which sticks due to static electricity.  

“We are soon going to launch a company focused on self-powered, non-invasive healthcare sensors using triboelectric technology. Innovations like these will enable us to drive new spin-out activities in sustainable health tech, improve sensitivity, and emphasize industrial scalability,” said Dr Bhaskar Dudem, Research Fellow.

With the ever-increasing technology around us, it is predicted that in the next few years, we will have over 50 billion Internet of Things (IoT) devices that will need energy to be powered. 

Local green energy solutions are needed, and this could be a convenient wireless technology that harnesses energy from any mechanical movements to power small devices.

It allows the scientific and engineering community to find innovative and sustainable solutions to global challenges.

“We are incredibly excited about the potential of these nanogenerators to transform how we think about energy. You could also imagine these devices are used in IoT-based self-powered smart systems like autonomous wireless operations, security monitoring, and smart home systems, or even for supporting dementia patients, an area in which the University of Surrey has great expertise,” said Professor Ravi Silva, director, Advanced Technology Institute (ATI) and Head of NanoElectronics Centre.
