SUNPOWER SOLAR ELECTRIC YACHTS are powered with a solar electric propulsion system thatcan cruise up to 100kms a day without fuel. Sunpower Yachts have an unlimited range at low speeds between approximately 4-6knots meaning no fuel gifting you with clean air cruising permanently. SUNPOWER Yachts solar system charges the battery banks that powers the e-motors on the yacht. The SUNPOWER yachts short term top speed is approx.
20knots with specific selected propulsion systems. The system will also power all inhouse appliances like the fridge, stove, cooktop, water makers, tv, lights and air-conditioning to fulfil all energy needs onboard.

Sunpower-yachts news & stories
Solar Panels are integrated in the roof, so there is no wind-load 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 for marine operation. All parts exposed to the marine environment are made of corrosion-resistant materials. All components are virtually free of maintenance. So the operating-costs are much lower than on a comparable conventionally powered catamaran.
Lithium-ion batteriesthat are light weightprovide sufficient energy for the propulsion system to run. There are many different types of lithium-ion batteries available for purchase. However, they vary in price dramatically if you are looking for quality. The brand we use is defiantly among the most expensive ones in the market. The reason we purchase this type of lithium-ion battery is the fact that they are best regarding packaging, liability, safety, performance, weight after sales service and life-span.
Engine roomsbuild up quite a lot of heat that e-motors do not so this can become a problem on large boats especially on hot days. Petrolengines projuce about seventy percent 70 % of the energy in form of heat. Electric-motors with an energy-efficiency of more than 90 % produce less than 10 %. Also, the gas burners stoves and ovens you may find in a yachts/boatsproduce a lot of heat into the interior of the yacht. As the inductioncooktops do not have an open flame, the inside of the yacht stays comfortably cool using no expensive dangerous or harmful gasses. SUNPOWER YACHTS are equipped with anespecially designed ventilation system.
Sunpower Yachts Comfort
Comfort depends on the way you have to go about obtaining power.
- If electricity is always available with no impact to the planet should be first and foremost, Sunpower yachts have achieved this through design. Electricity is always available gifted by the sun injected into the solar panels.
- All kinds of electric appliances can be connected to the system setup. You do not need to use fuel generators to use all your onboard appliances, you can also use all lighting when needed without a worry.
- Watermakers are a real gift as now you do not even have to worry about water supply whilst on a large holiday or journey. Watermakers can produce up to 3.000L of drinking water per day giving you the comfort that you would not have previously had in the past. Sunpower yachts is to have comfort with zero emissions.
Engine Maintenance & Service of Propulsion System Integration
Engine maintenance and service in regards to electric motors do not need any service for up to 50 years. This will give you peace of mind knowing that you have reliable electric motors. If you have fuel engines the maintenance is continuous with oil and rusty water leaks from normal fuel engines. Electric motors we use have a 8 year warranty.
The diesel generator which also can extend your range requiresvery little maintenance depending on use and how fast you wish to travel.
Solar panels have a guaranteed life-span of more than 25 years. After that time they can be replaced a panel at a time if needed.
Lithium-ion batteries have a guaranteed lifespan of 8 years, as a complete package it has a much higher warrenty than any petrol engine package would give you.
Electric-motorsare completely free of maintenance. So, the maintenance-costs are much lower than on a comparable conventionally powered catamaran.
Performance and Efficiency:
Sunpower yachts have custom made foam core e-glass that is 30 percent lighter than other yachts internal bulkheads and stringers yet is also stronger and engineered to the highest level. Yes, it is more expensive to make but our team focus on custom quality builds. The hulls are made by optimizing slower speeds unlike other yachts and boats which would use higher speeds this allows the slimline hull nose cone to cut through the water faster with less drag. SUNPOWER Yachts propulsion system works together in harmony.
