In 2010 Solarwave 46 was the first oceangoing yacht which powered 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 bord. But a lot of luxury - noiseless and fumeless.
After several years of testing Michael Köhler and his wife Heike developed this unique concept of an independent energy-supply. In 2010 the Solaryacht started a rigorous 5 years sea-trial. They crossed the whole of Europe by river, sailed the dangerous Black-Sea, the stormy Aegean and the Med. This experience of more than 120 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-engine. The generator, which has to be on board for safety-reasons, was working for approx. 50 hours - primarily to avoid becoming rusty...during the same period of time the electric motors worked more than 2.000 hours...without any maintenance.
This was the proof, that this technology is head and shoulders above all other types of propulsion.
Do you know of another luxury sailing-yacht, that is able to sail more than 12.000 miles in all conditions, only using diesel for approx. 50 hours?
That is what Solarwave did!
This is the proof for the suitability for everyday use of Michael Köhler´s "Solarwave-System".
The "Solarwave-System" has been awarded with the "Energy-Globe-Award".
