Premium technology


SUNBEAMsystem is a market leader in high-performance solar panels for the most demanding circumstances. Most popular applications include the professional marine yachting industry and extreme off-grid environments, ranging from both arctic to tropical climates.

Tough has become even Tougher

All our models have been structurally improved with stronger and more sturdy cell protection.

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.

Marine Solar Panels

The Amazing

Shadow Optimized technology

In models featuring the Shadow Optimized label, the solar cells are internally divided into multiple groups, connected in parallel, allowing them to function independently from each other.
Because of this, a single solar panel with Shadow Optimized technology is essentially build up from two separate internal solar panels. This means that when one part of the solar panel catches less light or is shaded, the other part can continue to generate electricity at full power.

About Our Solar Panels

What is the recommended fitting method?

Choose the correct model for the intended use.

  • Foldable solar panels for temporary use.
  • Carbon & QuickFix for Canvas use.
  • Flush models for permanent fitting on a hard & even surface.

Wrongful use might render damages to the solar panel.

Read our fitting instructions.

How do I choose the best panel for me?

SUNBEAMsystem has a model for every need (except for the very cheap solar panels). Every price segment has higher quality and more innovative features compared to the others.
The best tip we can offer is to compare our models as you would when comparing them with competitors.

  • Build Quality \ Component Quality \ Expected lifetime \ Warranty
  • Efficiency \ Watt per surface
  • Output in partial shadowing situations
  • Usability \ How to integrate \ How to fit

Hopefully, this will help you in finding the most suitable model for you.

Should I connect multiple solar panels in parallel or serial?

For the best possible output, we do recommend connecting several solar panels in parallel. The connection in parallel will also safeguard the best possible life expectancy of the solar panels.

On a surface, with often recurring shadowing it is smart to be able to spread out the solar panels. Hence several solar panels spread out are most often much better than a big one.

For a very big surface, group similar panels and have one solar charge controller per group.

Another tip is to choose a charge controller that works well with solar panels in parallel. A solar charge controller that allows the true potential of the solar panels when connected in parallel. Read more about it in our extended F.A.Q.

I have constant energy deficit - I need a solar panel! Is it a D.I.Y. project?

The nice thing with a Yacht or motorhome is that it already has a battery and the power “infrastructure” in place. You only need to hook up the solar panels via a charge controller.

We do have the market’s best batteries. But you will usually solve a lot of energy issues simply by adding solar panels.

In general, it is very easy to install a solar panel. What might be somewhat complicated is to find the way where to route the cable. If that seems too overwhelming, then consider a temporary solution. One mobile solution is to use our Tough Fold + Mini-R Charge Controller.
