Meet the first high-tech luxury yacht 100% powered by the sun
GREEN even when BLACK and beautiful from every angle

We are pleased to introduce the unique 100% solar powered yacht and take a new step into the world of future luxury yachts. SUNRAYA features innovative design and the world’s latest technology achievements what puts the yacht building into the new era of sophistication and performance.

The combination of sporty lines, space, elegance, luxury, high-end technology and performance delivers the highest level of on-board comfort, safety and independence. With the silence of sailboat and the power, speed of a motorboat, SUNRAYA offers the best possible lifestyle on water.

Ultra modern solar plant & Energy storage

There are many factors that affect the performance of solar cells, however, the yacht’s solar plant must generate electricity under a various environmental conditions from dawn to dusk. SUNRAYA is equipped with high-energy efficiency, lightweight thin-film Gallium Arsenide (GaAs) solar cells which naturally performs better at converting the sun’s energy into electricity than other materials. Powerful yacht needs lot’s of energy, but at the same time should remain as light as possible. Lithium Sulfur cells of which consists the energy storage unit, helps to achieve this. These cells are safe, long life, lightweight and have many advantages.

  • SUNRAYA is equipped with high-energy efficiency, lightweight thin-film Gallium Arsenide (GaAs) solar cells. GaAs naturally performs better at converting the sun’s energy into electricity than other materials and deliver more energy in high heat or low light – two of the most common real-world conditions for solar cells.

    Yacht is equipped with more than 35,000 solar cells. Conversion efficiency over 28%, area covered – over 360 sqm, low temperature coefficient and high sensitivity to low light.

  • Partially fluorinated semi-crystalline polymer is used for solar cells encapsulation. This is a high-tech laminate which protects the PV cells from UV rays, heat and moisture while acting as an electrical insulator.

  • Lithium Sulfur cells are maintenance free, safe, long life and lightweight. They meet international standards concerning shock, crush, thermal stability and short circuit (UN38.3, IEC62133). Ceramic lithium sulfide passivation layer and a non-flammable electrolyte helps cells withstand extreme abuse situations.

    One megawatt Lithium Sulfur energy storage unit. 100% depth-of-discharge, lightweight, safe, long life, non-flammable and maintenance free.

Lightweight, Sporty, Unique & Dynamic

Everyone knows the direct dependence of dynamics and weight. Therefore, the main task of our team was to design the yacht lighter not two, not five, but almost eight times compared to other yachts in this class. And when it comes to lightweight materials, the only aerospace industry can offer suitable products and technologies. The low yacht weight and electric propulsion provides excellent dynamic characteristics – you can cruise with pleasure at 30 knots and reach the maximum speed of 45 knots. And all this without thousands of horse power and without a single drop of fuel.

  • Structure is designed in such a way to minimize the vessel’s weight maximally, and find the balance within luxury, comfort and performance. Reinforced with Kevlar carbon fiber and vacuum resin infusion technology provides highest possible hull strength properties and huge weight savings.

Space, Interior & Materials

SUNRAYA comfortably accommodates 8 guests in her four spacious and luxurious staterooms with en-suite bathrooms. All staterooms are situated below deck, offering privacy and tranquility. The unique contemporary interior design will be developed in close collaboration with the owners using latest high-tech, natural and lightweight materials. Spacious interior, floor-to-ceiling windows in the main saloon and large stateroom windows provides unobstructed sea views and an abundance of natural light. Moreover, each stateroom is equipped with the Nanoparticle lighting system, which perfectly mimics the feel of sun and daylight. There is also a large sundeck area for the outdoor living.

  • Dynamic windows allows you not only to tint and clear windows on demand, but also to control unwanted sunlight, heat and glare. Admitting natural daylight and rejecting unwanted solar glare it’s easy to create comfortable atmosphere inside.
