HIGH-EFFICIENCY SOLAR CELLS

Flat Flush Cable

UV-Proof & Antislip

3M Mounting

5 Year Warranty
for professional purposes and high-end installations
The SUNBEAMsystem Tough+ series is developed for professional purposes and high-end installations. All models are fitted with Sunpower™ cells with an efficiency of no less than 23.7%, resulting in a high production on even the smallest surfaces.
Tough+ is equipped with the same superior materials that have previously been developed for the original Tough series by SUNBEAMsystem. The innovative Tough surface offers a longer lifespan than any other thin and lightweight solar panels. 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.
Bigger sized Tough+, 116W and 82W, comes with the Protected Shadow Optimized design to improve output in partial Shadowing conditions.
Being only 3mm thin, the panels can be seamlessly integrated on any hard surface (both flat and slightly curved). The flat SUNBEAMsystem Flush power cable will be invisible after installation, leaving no external wiring exposed, resulting in a robust and durable end result.
The Tough+ series is shipped without stainless steel eyes and includes a separately packed double-sided 3M sticker sheet for easy mounting. If you prefer to use a kit instead, we recommend a soft flexible glue like the white Sikaflex 291i or 591.

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.

5th Generation Junction for Superior Flush Results
The result of a decade of pioneering, our protected design offers two cable routing options: outside the panel or through the hull.

F – SILICONE PROTECTION
5th Generation Junction for Superior Flush Advantages:
- Up to 6% output increase thanks to the layout and direct string connection
- Improves aesthetics
- Prevents intrusion and pressure on the panel
- Resists breakage from stepping
- Tackles heat-induced reshaping and zigzagging
G – Flat Flush Cable
Our unique, in-house developed cable provides these advantages:
- Flexible: Surface-run or run internally (double folded)
- UV-protected, pre-tinned for marine durability
- Slim cable with 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.
