for professional purposes and high-end installations

Tough+ has been developed for professional purposes and high-end applications. Fitted with Sunpower cells featuring an impressive 23.7% efficiency, these models are the first choice for any user that’s ready to put the highest demands on their panels.

The 5 Dimensional Solar Panel

SUNBEAMsystem’s Tough series sets the standard for durability and longevity in solar panel technology. Our unique five-dimensional approach results in exceptional build quality, where each aspect works together to boost overall performance

  1.  Enhanced Outer Protection Layer
    Our proprietary layer offers unmatched UV resistance and transparency, surpassing other types of ‘premium’ surfaces
  2. Premium Sunpower Cells
    These high-end cells provide superior efficiency (more Watts/m2), wider light spectrum capture, longer lifespan, and a deeper black color.
  3.  Advanced Conduits & Durability Core
    Robust internal conduits within multiple protective layers ensure lasting performance.
  4. Shock Absorbing Layer
    All solar cells and wiring are embedded in a distinct shock-absorbing material, enhancing their longevity.
  5. Sandwich Composite Stiffener Layer
    A lightweight, high-tech core that optimally maintains structural integrity, offering near-metal properties without the delamination risk of combining metal with plastics.

Flushed Soft Junction

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

Soft Junction advantages

● Boosts output by up to 6% due to direct solar cell string connection.
● Improves aesthetics – a truly cable-free installation.
● Eliminates intrusion and pressure on the solar panel.
● Prevents breaking forces when walking on it.
● Counters heat-induced reshaping of the solar panel.

 

The advantages of our unique, in-house developed flat Flush power cable

● Versatile: can be entirely concealed or have minimal height on the surface.
● UV-protected and pre-tinned for maximum durability in marine settings.
● Features a thick, low-loss core within a compact jacket, only 1.2mm tall.

Series & Cell Comparison

Our partnership with Sunpower grants us special access to the highest grade, state-of-the-art solar cells, enhancing our panels’ craftsmanship. Despite prevailing assumptions, not all Sunpower cells are alike; lower-cost options will not match performance of premium cells. This distinction is crucial, as high-quality cells elevate our superior craftsmanship. Below are essential performance criteria for comparison:

● Longevity: This measures the panel’s durability under various conditions, particularly in partially shaded environments. High-quality cells (more expensive) are less sensitive, leading to an extended lifespan.

● Shadow-Optimized Boost: Premium cells minimize heat and power loss when partially shaded, enhancing our Shadow Optimizing technology for an even greater power boost.

● Efficiency: Efficiency is directly proportional to output; higher efficiency means more power generated from the same surface area under all conditions.

● Aesthetics: The appearance of the cells, with high-performance cells displaying a deep, uniform black color, is especially important for black panels.
