Sungold Marine
Solar Power Solutions
If you’re heading out to sea to escape the roar of diesel engines, reduce the hassle of frequently finding shore power sockets, or avoid constantly worrying about battery levels, a well-designed Sungold marine solar system can change all that.
Why Choose Marine Solar Now?
On a yacht, electricity is not just about comfort, but also about safety and confidence. With high-efficiency marine solar panels, you can harness clean, renewable energy even in remote waters. These panels are built to withstand harsh marine conditions, ensuring reliable power for navigation, lighting, and onboard appliances. Enjoy the freedom of longer voyages and peace of mind knowing your energy needs are met sustainably with Sungold’s advanced marine solar panels.

No reliance on shore power or generators, allowing you to explore the ocean more freely.
Continuous Power for Critical Equipment
Provides stable power for navigation, refrigeration, communication, lighting and other critical equipment.
Support Off-Grid Living
Reduce fuel noise and pollution, enjoy a purer sailing experience.
Flexible & Thin Design
Perfect for small or curved installation spaces like hardtops, awnings and deck areas.
Marine Solar vs Regular Panels
The marine environment is harsh, and ordinary solar panels struggle to adapt. Sungold panels are specifically designed for marine use, balancing performance, reliability, and aesthetics to ensure clean installation and long-lasting durability.
Engineered with corrosion-resistant materials and advanced waterproofing, they continue to deliver consistent power even in the toughest conditions. With Sungold marine solar panels, you can enjoy uninterrupted energy and a worry-free boating experience.
Marine Solar Features
- Salt Mist Resistance - Withstands long-term sea breeze corrosion
- UV Resistance - Adapts to prolonged sun exposure
- Bending & Vibration Resistance - Continuous hull movement in waves won't damage components
- Custom Geometry - Matches irregular spaces of cabin tops, masts, hatches, and decks
Why Adaptation Matters
Most yachts have many irregular or non-rectangular spaces. Sungold’s customized panels can flexibly match:
- Triangular areas (near mast bases)
- Narrow spaces (lifeline stanchions, cabin top sides)
- Curved decks or hardtops
Through customized design, improve wattage utilization while maintaining deck cleanliness and integrated appearance with the hull.
Three Reliable Installation Methods
To ensure safety and long-term durability, Sungold recommends three installation methods. Each method is carefully designed to maximize panel stability and energy efficiency under marine conditions. Whether mounted on flat surfaces, curved decks, or flexible Panel structures, the installation options provide secure and reliable performance. Proper installation not only protects your panels from harsh weather but also ensures optimal power generation throughout your voyage.
Grommet & Screw Installation
Aluminum backplate + stainless steel fasteners, suitable for high sea conditions.
3M Industrial Double-Sided Tape
Suitable for fiberglass or composite surfaces, clean and mark-free, no drilling required.
Neutral Silicone Adhesive
