Sunpower-ALVA Solar-e 90 – Award-Winning Innovation, Powered by the Sun

Step aboard the Sunpower-ALVA 90, an award-winning flagship of solar-electric innovation — a superyacht that represents the pinnacle of sustainable luxury. Purpose-built for those who seek grandeur without compromise, the Sunpower 90 offers a yachting experience that is as revolutionary as it is refined. With its commanding presence and industry-leading technology, this vessel is setting a new global standard in the world of clean, conscious cruising.

At 90 feet in length, this solar-electric catamaran is in a class of its own. Every detail has been meticulously crafted for maximum efficiency, elegance, and onboard luxury. With its wide beam and sleek silhouette, the Sunpower-ALVA 90 offers expansive living areas — indoors and out — all powered silently by an advanced solar energy system paired with cutting-edge electric propulsion.

The interior is a sanctuary of modern design and intelligent space. The vast open-plan saloon flows effortlessly into the aft deck, creating an ideal environment for lavish entertaining, gourmet dining, or simply indulging in peace and privacy. Floor-to-ceiling windows and skylights illuminate the interior with natural light, while fully customizable layouts cater to full-time living, elite charters, or extended global cruising.

Above, the flybridge is a true showpiece — a floating rooftop retreat with options for a spa pool, cocktail bar, dining area, sun loungers, and helm station, all offering sweeping 360° views. Forward, the bow lounge provides an intimate escape for sunbathing, evening cocktails, or quiet reflection with the horizon ahead. The hydraulic swim platform offers direct access to the ocean, your tender, or a fleet of water toys.

This award-winning vessel is not only beautiful — it's a breakthrough in responsible innovation. With zero emissions, ultra-low maintenance, and complete energy independence, the Sunpower-ALVA 90 invites you to explore the world in absolute freedom and silence — from the Mediterranean to the Maldives, the Caribbean to the South Pacific.

This is more than a superyacht.

This is the future of yachting. This is Sunpower living — where vision meets victory, and every voyage is powered by the sun.
