The best Tough features

but with a discreet black look

The SUNBEAMsystem Black series has been specifically designed to integrate as best as possible into the surface they are mounted on. Due to the dark color, the Black models fit really well on even colored surfaces. Wherever there are high aesthetic requirements on the looks and design of an installation: the Tough Black series is your best solution. On both historic as well as on hypermodern yachts.

Whether this background is pure white or a classic brown: nobody will suspect there’s a solar panel hidden behind the all-black surface.

High-Efficiency Cells

Get the most out of every space

THE TOUGH BLACK SERIES is available in five different models

The Tough Black Solar Panels series starts with models from 55w up to 114w. And all five models feature the SunpowerTM Maxeon cells with an efficiency of 22.5% or higher. As well as the SUNBEAMsystem Shadow Optimized technology.

The Unique Tough Black 55w Long is perfect for applications where you don’t have that much space. It is a black and long solar panel that can fit in a variety of places in your yacht or motorhome. It can also be very useful for small boats, rolling boats, and off-grid applications. With the Tough Black 55w Long it is easy to make great use of a space that otherwise wouldn’t be producing energy.

Inside the Tough solar panel 

The name “Tough” in our solar panels represents their exceptional durability and longevity, as well as their enhanced energy output, thanks to the numerous innovative components that make up the panel. 

A - Enhanced Outer Protection Layer

Featuring exceptional UV-durability, surpassing the MAXA range and other high-end industry standard panels. 

B - Premium SUNPOWER® Cells

• SUNPOWER cells provide the foundation for exceptional performance, but by selecting even higher-grade cells than the standard SUNPOWER cells, we consistently achieve top results in independent tests. The difference in refinement levels among these cells is quite significant. While the cells used in MAXA and other high-end industry standard solar panels with standard SUNPOWER cells are good enough, upgrading to higher-grade cells offers improvements in each step up in the product range. 

• See the comparison table down the page.

C - Internal Electrical Circuits

Engineered for exceptional durability and high outputs, our solar panels feature backup pathways and heavy-duty cabling designed to withstand power surges and temperature fluctuations. This unique design is not found in other solar panels on the market. 

D - Shock Absorbing Layer

• Combines a soft top layer with a rigid bottom, effectively dampening shocks from above. Proper installation can even absorb the energy from a hammer dropped from a height. 

E - Ultra-Slim, Lightweight Stiffener Layer

 Our superior stiffening method surpasses competitor standards:

• Addresses solar curve & attachment-induced material fatigue
• Prevents heat-related reshaping, zigzagging, & associated microfractures
• Improves adaptability to surface irregularities
• Offers extra protection during installation

5th Generation Junction for Superior Flush Results

F - Silicone Protection

The result of a decade of pioneering, our protected design offers two cable routing options: outside the panel or through the hull. 

The Junction provides these advantages: 

  • Boosts output by up to 6% through its layout and direct solar cell string connection.
  • Improves aesthetics upon attachment (utilize the included 3M base sticker).
  • Eliminates intrusion and pressure on the solar panel.
  • Prevents breaking forces when walking on it.
  • Tackles heat-induced reshaping and zigzagging.

G - Flat Flush Cable

Our unique, in-house developed cable provides these advantages: 

  • Versatile: Run along a surface or double fold and treat like a standard cable.
  • UV-protected and pre-tinned for ultimate longevity in marine environments.
  • Despite its slim appearance, the cable features a thick, low-loss core.

With each product level elevation, four improvement aspects of solar cells are augmented:


– Longevity – Improved durability in various challenging conditions, especially in partially shaded environments, leading to a longer lifespan.

– Shadow optimized boost – High-end cells reduce heat and power loss during partial shading, further enhancing the unique Shadow Optimizing™ technology, providing an even higher power boost.

– Efficiency – The higher the efficiency, the greater your output on the same surface area under all conditions.

– Aesthetics – Deep Black, Even Colored Cells on the High-Performance Solar Cells.

TOUGH BLACK is the most discreet solar panel for boats
