Five of the Best Solar Powered Yachts of 2023

• Thursday 10 December, 2020

Silent Yachts founder Michael Köhler drew plenty of laughter across the industry back in 2005 when he announced he was moving away from diesel to build solar-powered luxury marine vessels. When his Köhler’s Solarwave 46 was launched five years later, though, those laughs turned to gasps.

Despite the limitations and expense surrounding the technology back then, he had achieved a stylish creation that had all of the mod cons and ran purely on the power of the sun. It should come as no shock then that Silent Yachts leads off our list of the top five solar-powered yachts on the market today.

Solar powered yachts are becoming increasingly popular in Australia, with more and more people looking for eco-friendly and sustainable ways to explore the country’s stunning coastline. These vessels harness the sun’s power to provide a clean and renewable energy source, reducing the need for fossil fuels and helping to protect the environment. With so many options on the market, it can be difficult to know which yacht is the best for you. To help you make an informed decision, here are five of the best solar powered yachts for sale in 2023.

The solar-powered Catamaran Silent 55 combines eco-friendly propulsion with luxurious accommodations. It is a 55-foot ocean-going catamaran with four staterooms and restrooms that is solar-powered and self-sufficient. The only mechanical components that need maintenance are the generators; there are no engine noises or vibrations.

The most powerful E-Power+ propulsion option, which combines the largest battery bank with the strongest electric motors, is available on this fully equipped vessel. As a result, faster speeds can be maintained for much longer while optimising the amount of energy stored for backup and used when necessary. E-Power+ provides the best solar-powered yachting experience.

Solar catamaran 100% powered by heterojunction modules headed for Australia

The 100% solar-powered boat will be tested in a 9,000 nautical mile expedition from Chile to Australia that is set to start in December. The vessel is equipped with an 11 kW PV system built with heterojunction modules provided by Russian manufacturer Hevel Solar.

Hevel Solar

From pv magazine Global

A catamaran designed by English racer and engineer Phil Morrison  and set to undertake a  100-day solo transatlantic trip from Chile to Australia will be exclusively powered by a PV power generator.

The boat will be helmed by Russian adventurer and survivalist Fedor Konyukhov in a first-ever solo transpacific 9,000 nautical mile expedition from Chile to Australia, which is set to start in December.

Called Nova, the vessel is 11m long, 7m wide and able to reach speeds of 5-7 knots. It is made of carbon-fibre composites and weighs only 2.2 tons. “The craft is designed to break down into two hulls and four deck sections, which together with ancillary equipment, launching and assembly, will fit into two 40ft containers,” Morrison said in a statement.

The boat is equipped with an 11 kW PV system built with flexible heterojunction solar panels developed by Russian module maker  Hevel Solar . “T he cost of solar elements plus labor and without the storage system was RUB 1.1 million, which makes up to €12,000,” a spokesperson from the manufacturer told  pv magazine .

The solar array will cover a surface of around 66 m2 on the vessel and the sides of the hull will also carry panels, providing an additional 12m2 per side. “Whilst these panels are not expected to be as efficient as the deck panels it is hoped they will gather valuable additional energy when the sun is low on the horizon and from light reflected off the water surface,” Hevel Solar explained.

The PV system will also ensure the supply of freshwater, as the boat is equipped with a desalination system powered by solar-generated electricity itself.

The catamaran is also equipped with an energy storage system designed by Enel X, a unit of Italian utility  Enel . The system relies on 26 Li-Fe-phosphate batteries to ensure a stable power supply for the PV system, which could peak in excess of 5 kW in ideal conditions.  “Sophisticated MPPT charge controllers capable of adjusting the current and voltage to maximise the charging potential will be allied with a complex monitoring system allowing the craft to optimise the power obtained,” Morrison stated.

Nova is claimed to be able to navigate with full autonomy in the ocean for up to six months.

The boat was also conceived with technologies provided by Mikhail Lifshitz, general designer at ROTEC JSC, which specialises in developing methods to power sea and river vessels using electricity-supplied engines, solar panels and the albedo effect.

The ZEN50 is a game changer. World’s first series production catamaran equipped with a wingsail, it defines a new distinctive class of its own, where genuine zero-emission meets high comfort and performance, limitlessly. 

Designed from scratch for ZEN Yachts by award-winning naval architect Julien Mélot , this full carbon catamaran is the ultimate essence of technology driven, high performance and luxurious, eco-friendly leisure yachting. 

The blue water capable ZEN50 lightweight racing carbon hulls are combined with a huge solar roof for an unrivaled solar power vs. displacement ratio above 1:1 (18 kW / 17 tonnes), making this yacht completely energy self-sufficient. A revolutionary, fully automated, wingsail - by Ayro© - can be added as a range and speed extender. The yacht’s high capacity battery bank powers a powerful silent electric propulsion, allowing the ZEN50 to achieve 14 knots and maintain high continuous speeds in unrivaled safety and comfort, indefinitely… 

The ZEN50 is offered with or without wingsail and comes in 3 main different versions: Racer, Cruiser and Explorer, each dedicated to a different usage and owner profile. We use these versions as a basis to define a final, bespoke specification for each of our valued clients and ZEN Community Members. Scroll down for more details, specifications and prices.

1st WINGSAIL series production yacht in the world!

The OceanWings32 - by Ayro© - was initially developed for Team Oracle, for the America’s Cup 2010 in Valencia. Over years, it has further been developed and automated by VPLP and was installed on Energy Observer in 2019. Two years of field feedback have allowed the Ayro team to fine tune the algorithm commanding the wingsail. The ZEN50 is the first series production leisure craft to be equipped with this fully automated wingsail. It is controlled at the touch of a finger on screens, is automatically adjusted and has several safety modes and features. The two parts of the wingsail can be hoisted and lowered independently and with the simple touch of a button. The wingsail OceanWings32 is the ideal complement for the solar roof for those wishing to cruise long distances off-shore with zero-emissions.

Greatest ratio SOLAR POWER / weight on the market

At 17 tonnes lightweight and 18,000 W of peak solar power, the ratio of the ZEN50 is at over 1 kW per displaced tonne of water or beyond 1:1 which is far beyond any other blue water CE Cat A yacht in this size range. Lots of solar power for little water to displace is the strong and healthy foundation the energy self-sufficient ZEN50 is built upon.

Performance CARBON sandwich hulls

The hulls of the ZEN50 have been designed from a blank screen for ultimate efficiency - understand minimum drag or minimal energy consumption for a range of speeds from 6 to 10 knots. Their shape is aggressive, sharp and slender. Their reverse bows cut through water like a sword cuts through butter and their curvature is reminiscent of graceful dolphin bodies. These hulls are undoubtedly of the performance type and are built with the best available composites: Carbon fibre and Corecell™. The combination of high strength, low weight and performance design allow the ZEN50 to reach speeds of up to 14 knots.

INFINITE range at high CONTINUOUS speeds

With maximized solar and wind power and minimized energy consumption… the ZEN50 can sail continuously at speeds varying between 6 and 10 knots. Thorough simulations in various sea states and weather system have consistently shown the ZEN50 will be able to achieve performance catamaran speeds continuously without using a genset. With the ZEN50, the world is your oyster and the wildest destinations are within your reach with this self-reliant vessel!

True ZERO-EMISSION operation

The first ZEN50 unit, whose construction started in March 2023, will not be equipped with a genset at all and will not have any fossil fuels onboard. The ZEN50 energy system with its very large capacity 160 kWh battery bank, has been designed to function for days in complete safety with minimal solar energy harvest and no wind. It is perfectly safe with no backup genset and operates 24/7 without any polluting emissions.

NO FUEL , no costs

Naturally, requiring no fuel to operate day in day out is great news for the environment, it is also fantastic news when sailing into remote areas where fuel bunkering might be near impossible or where the fuel quality might be an issue. Finally, it also makes a massive difference in this yacht’s costs of operation. Imagine the hundreds of liters of diesel saved over just a week, the obsolete engine maintenance schedules, the clogged filters and dirty tanks from another age… Welcome to a new burden-free, energy self-sufficient era, welcome to clean and graceful eco-yachting, welcome to ZEN Yachts.

Highest SAFETY & reliability

At ZEN Yachts, we have made some design choices to attain energy self-reliance with the ZEN50 that reduces the habitable volume in the hulls, similar to performance catamarans. Where we have not and will never compromise is on safety. Our main voltage system is 48V making it perfectly safe to work on. The level of redundancy of the batteries and solar panels is 10! The main electrical architecture is split in 2 so that should anything happen on 1 hull, the entire vessel can still operate normally. There are 2 independent helm stations and the ZEN50 is packed with special safety features, nonsubmersible compartments and we can even offer an in-depth practical course on safety equipment usage and management. Sailing with the ZEN50 is not only exhilarating and clean, it is ultra safe!

Unrivaled space & COMFORT

The ZEN50 offers the speeds of a performance catamaran, the comfort of a large motor yacht and the simplicity of an electric car. No less than 2 large day beds, 3 dining areas for over 10 people, 1 professional galley and 2 wet kitchens, 5 heads, up to 4 double ensuite cabins, 1 bunk double and 1 single together with both saloon and dining areas converting into extra sleeping areas, this is simply unrivaled on a 50 ft. catamaran. Add an electric tender, dive compressor, satellite internet, 2 helm stations (cockpit and flybridge), a solar roof that converts into a gigantic upper deck to enjoy the most epic sunrises and sunsets, welcome onboard the ZEN50!

Solar catamaran 100% powered by heterojunction modules

The 100% solar-powered boat will be tested in a 9,000 nautical mile expedition from Chile to Australia that is set to start in December. The vessel is equipped with an 11 kW PV system built with heterojunction modules provided by Russian manufacturer Hevel Solar.

A catamaran designed by English racer and engineer Phil Morrison and set to undertake a 100-day solo transatlantic trip from Chile to Australia will be exclusively powered by a PV power generator.

The boat will be helmed by Russian adventurer and survivalist Fedor Konyukhov in a first-ever solo transpacific 9,000 nautical mile expedition from Chile to Australia, which is set to start in December.

Called Nova, the vessel is 11m long, 7m wide and able to reach speeds of 5-7 knots. It is made of carbon-fiber composites and weighs only 2.2 tons. “The craft is designed to break down into two hulls and four deck sections, which together with ancillary equipment, launching and assembly, will fit into two 40ft containers,” Morrison said in a statement.

The boat is equipped with an 11 kW PV system built with flexible heterojunction solar panels developed by Russian module maker Hevel Solar . “T he cost of solar elements plus labor and without the storage system was RUB 1.1 million, which makes up to €12,000,” a spokesperson from the manufacturer told pv magazine .

The solar array will cover a surface of around 66 m2 on the vessel and the sides of the hull will also carry panels, providing an additional 12m2 per side. “Whilst these panels are not expected to be as efficient as the deck panels it is hoped they will gather valuable additional energy when the sun is low on the horizon and from light reflected off the water surface,” Hevel Solar explained.

The PV system will also ensure the supply of freshwater, as the boat is equipped with a desalination system powered by solar-generated electricity itself.

The catamaran is also equipped with an energy storage system designed by Enel X, a unit of Italian utility Enel . The system relies on 26 Li-Fe-phosphate batteries to ensure a stable power supply for the PV system, which could peak in excess of 5 kW in ideal conditions. “Sophisticated MPPT charge controllers capable of adjusting the current and voltage to maximize the charging potential will be allied with a complex monitoring system allowing the craft to optimize the power obtained,” Morrison stated.

Nova is claimed to be able to navigate with full autonomy in the ocean for up to six months.

The boat was also conceived with technologies provided by Mikhail Lifshitz, general designer at ROTEC JSC, which specializes in developing methods to power sea and river vessels using electricity-supplied engines, solar panels and the albedo effect.

Sustainability at sea: Sunreef is integrating recycled plastic bottles into solar electric yachts

Sunreef Yachts is already a solar electric boatbuilder recognized for its sustainability efforts in the maritime industry but is now taking things a step greener. The company is now integrating recycled PET bottles into its solar electric yacht production process.

Sunreef Yachts  has been operating out of Gdansk, Poland, for over 20 years alongside a newer footprint established in the United Arab Emirates. From day one in 2002, Sunreef has been pushing the boundaries of sustainable marine travel, launching the world’s first 74-foot luxury oceangoing catamaran with a flybridge.

Sunreef Yachts currently has hundreds of its boats sailing waters across the globe, showcasing the company’s lineup of sustainable, all-electric propulsion and advanced solar panels. Its current portfolio consists of eco-friendly sailboats and  massive solar electric catamarans  ranging from 60 to 100 meters in length.

In April 2024, Sunreef introduced a new 40m electric yacht called the Eco Explorer . One month later, Sunreef shared a new sustainability strategy that will integrate hundreds of thousands of recycled polyethylene terephthalate (PET) bottles into the superstructures of its electric yachts.

Sunreef’s electric yacht reuses 600k recycled PET bottles

As part of a new initiative to maximize energy efficiency and, above all else, sustainability, Sunreef Yachts Eco’s R&D team will integrate a structural foam composed of up to 100% recycled PET materials into the production of its solar electric yachts and sailing catamarans.

By integrating this recycled material, Sunreef can achieve even more eco-conscious electric yacht construction practices while furthering sustainability in a maritime segment that quickly embraces electrification .

In addition to being 100% recyclable, Sunreef shared that the recycled thermoplastic core offers additional benefits in electric yachts and catamarans, such as high resistance to process temperatures, exceptional chemical resistance, strong adhesion, and other mechanical properties.

For added perspective on the impact the recycled material can have on the industry, Sunreef said one of its 80-foot sailing catamaran requires about 2.4 tons of the structural foam, equating to approximately 600,000 recycled PET bottles finding a second life at sea within the superstructure rather than floating around as pollution.

This is the kind of news we love sharing with you readers and provides further evidence that large boats can not only be 100% electric but may soon be 100% recyclable.
