Solarwave yachts are Solar-Hybrid-Yachts, Solarwave has developed a system that reduces the operation-hours of diesel-engines and thus the consumption of fuel is close to zero. This system is modular and scalable.
The Solarwave is a 54-foot catamaran built by Switzerland-based Solarwave AG and it is equipped with an electric powertrain manufactured by Turkey-based Imecar.
On the roof of the Solarwave yachts high efficiency solar-panels of the latest generation recharge the light weight lithium-batteries. The special configuration of the components provides a unique energy-balance: The solar-panels produce more power, than a household and electric motors consume.
Efficiency and Weight
The underwater-lines are optimized by CFD and towing-tank tests. The impressive weight-reduction is a result of the bionic design and the use of carbon fibres and epoxy resins. The whole interior furniture is made of stiff and ultra-light honeycomb composite plates with laminated real wood-veneer. Furniture and tanks are structurally integrated into the hull. This reduces the weight significantly. Weight is nearly equivalent to consumption. Each kilogramm less means less energy required to move the boat.
A Solarwave-Yacht has only half the weight compared to a conventionally constructed and powered yacht. Thus Solarwave-Yachts have less wave-drag and friction. This unique efficiency makes them fast and enables self-sufficient propulsion.
Autonomy and Luxury
A Solarwave-Yacht has virtually unlimited range - also when the sun is not shining. In case of longer periods of bad weather, the range-extender starts automatically when the batteries are low. The energy is stored in the batteries and can also be used in bad weather-conditions and during the night. The light-weight Lithium-Batteries provide ample energy for the propulsion as well as for all household appliances - 230 V (110 V) day and night for television, air-conditioning, ice-machine, watermaker, laptop and much more. No need to search for a marina to charge the batteries, to get ice, to refuel or to fill watertanks.
The solar panels are integrated in the roof, so there is no windload on them. The batteries and electric-motors are inside the boat in a dry and safe place. All wiring is tin-covered and all plugs are specially designed so water or humidity cannot enter. All parts exposed to the marine environment are made of corrosion-resistant materials. All components are virtually free of maintenance.
History of the Solarwave®
Solarwave 46 - the Proof of Concept - launched in 2009.
There are hundreds of solar boats and thousands of electric boats all over the world. But Solarwave 46 is the first oceangoing yacht which powers the propulsion as well as all household appliances exclusively by solar. This includes induction cooktops, stove, microwave, grill, freezers and fridges, air-conditioning, washing-machine, watermaker, even the dinghy-motor and the electric motorbike are solar-charged. No fuel and no gas on board. But a lot of luxury - noiseless and fumeless.
With this unique concept of an independent energy-supply the Solar yacht started a rigorous 5 years sea-trial in January 2010. They crossed the whole of Europe by river, sailed the Black-Sea, the Aegean and the Med. This experience of more than 140 weeks was also enjoyed by hundreds of guests and visiting journalists. The functionality and sea-capability of this yacht were fully scrutinised and passed with flying colours. Solarwave accommodated 6 - 8 guests with electrically prepared full board, water-production, cooling and heating.
And on top of that Solarwave was able to power the engines - every day in any weather-conditions. In storms of force 9 as well as in calm, with sun, rain, cloudy sky, snowfall and ice. All exclusively with solar-power. During this period of 5 years there was no need for maintenance or repairworks, neither the solar-plant nor the batteries or the electric-motors.
The generator, which has to be on board for safety-reasons, was working for about 50 hours in five years - primarily to avoid becoming rusty .... during the same period of time the electric motors worked more than 2.500 hours ... without any maintenance.
Solarwave 46 is the proof for the feasibility and the suitability for everyday use of the "Solarwave-System". The "Solarwave-System" has been awarded with the Energy-Globe-Award 2012/2013 and with the i-novo Eco Award 2016.
