Since its introduction, the SUNBEAMsystem Tough Solar Panels Series has been the absolute winner in multiple real-life tests. All Tough models are fitted with SunpowerTM Maxeon cells with an efficiency of 22.5% or higher.
The anti-slip profile is not only practical for deck mounting; it also catches more light in low sun angles. In addition, the dirt-repellent properties also improve daily production by helping to keep the panels clean. It also provides a safe and walkable surface, without any cables to trip on.

The Amazing Tough Surface
The surface of the Tough Solar Panels is extremely durable and resistant to strong and long UV exposure. As a result, it transmits more light than standard materials, contributing to higher daily production.
All Tough Solar Panels models from 55W and up are equipped with SUNBEAMsystem protected Shadow Optimized technology, improving output in partially shaded conditions.
Tough models are equipped with a flat power cable that allows an incredible flushed installation.

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.
