Unlike traditional rigid solar panels mounted atop aluminium frames, the new Praxis solar system is a 2mm-thin nano-composite ‘solar skin’ bonded directly into the yacht’s hardtop during the moulding stage of construction. All visible layers are optically transparent, with a sleek black backing that integrates discreetly into Riviera’s sculpted superstructures with a contemporary aesthetic.

The solar surface follows the curvature of each model’s hardtop in multiple planes, maximising usable space organically across the yacht. The result: approximately 120 percent more power output from only around 90 percent additional surface coverage compared to conventional marine solar installations. This is not an add-on – it is a fully bespoke integrated energy architecture design for each Riviera model from 39 to 78 feet.

Riviera owner, Rodney Longhurst commented, “The pioneering efforts of our brilliant design team working in partnership with the credentialled Praxis team, have created an ingenious solution to reducing our yachts reliance on generated or shore power.

This is a significant breakthrough in many ways and with so many benefits from sustainability to enhancing the boating experience of Riviera yacht owners the world over. Our guiding principle at Riviera is always to make boating easier and more pleasurable, and this latest innovation attests to this.”

Real-World Performance, Proven at Sea

Extensive testing and early installations demonstrate compelling real-world results.

A recent 1.8kW installation in New Zealand aboard a 58 Sports Motor Yacht is generating approximately 10kWh per day, significantly extending time at anchor without generator engagement. In Mauritius, a Riviera 72 Sports Motor Yacht equipped with an expanded lithium iron phosphate battery bank can achieve up to three days off-grid without running a genset. Another owner reports operating air conditioning for more than a day and a half purely from stored solar energy.

On an extended passage in Australia from Queensland’s Gold Coast to Adelaide in South Australia, a Riviera 6800 Sport Yacht Platinum Edition fitted with the solar system maintained onboard systems while underway – supporting navigation equipment, refrigeration, lighting and digital control systems.

By feeding directly into the house battery bank, the integrated solar solution supports critical onboard equipment via the C-Zone system. This innovative system is shade tolerant, with different regions of the solar surface operating dynamically to optimise total output.

For owners, the benefits are clear: fewer generator hours, reduced diesel consumption, lower operational costs and a more refined and peaceful onboard experience.

Designed for the Demands of the Marine Environment

Praxis’ proprietary nano-composite technology is engineered at a microscopic level to deliver defect-free composite strength. The panels are 85 percent lighter than traditional rooftop systems and constructed from materials aligned with the yacht’s own composite build – ensuring durability against salt, heat, offshore movement and impact.

The surfaces are fully waterproof, virtually unbreakable and available in matte, gloss or non-skid finishes for new and retrofit applications.

“Solar integration had to meet the same structural and aesthetic standards as the yacht itself,” said Dan Henderson, Design & Engineering Director at Riviera Australia. “It was essential that this innovation enhance, rather than interrupt, the Riviera design language.”

The collaboration, initiated three years ago, involved close dialogue between Riviera’s design and engineering teams and Praxis’ specialists to refine curvature, optimise placement and ensure seamless integration within the mould-building process.

“When two innovation-driven industry leaders come together, the goal isn’t to follow the standard, it’s to redefine it,” explained Katie Donaldson, Founder & Executive Director, Praxis.

Riviera and Praxis have combined expertise to expand the art of the possible, seamlessly integrating silent luxury into the marine environment and setting a new benchmark for solar innovation.”

Responding to a Changing Global Market

Owner expectations have evolved significantly over the past two decades. Modern yachts function as fully equipped floating residences, with advanced digital systems, climate control and hospitality-level amenities demanding robust energy management.

At the same time, marina regulations in some regions are limiting shore power charging options. Integrated solar provides owners with the ability to recharge batteries underway before arrival, increasing autonomy and flexibility.

While sustainability is an increasing consideration across the global marine sector, Riviera emphasises that the innovation is fundamentally about the experience.

For Australian owners who favour extended off-grid cruising, the return on investment can be significant. In markets such as the United States, where marina-to-marina cruising is more common, the benefits include reduced operating costs and enhanced onboard comfort through quieter operation.

Now Available Across the Riviera Range

Integrated solar panels are now included as an option within Riviera’s new-build specification, with bespoke designs currently being finalised across the model range. Retrofit solutions are also available for existing Riviera yachts via the Riviera Aftermarket service located at the company’s manufacturing facility on the Gold Coast in Australia.

As one of the world’s most respected luxury yacht builders, Riviera continues to demonstrate leadership through purposeful innovation. With this collaboration, Riviera yachts signal a clear direction for the future of luxury motor yacht construction: intelligent, integrated and experience-led.
