Tough G8 Performance Black

Tough G8 Performance Black is designed for those who want maximum energy from minimal surface area. Performance cells with 24.4% efficiency, based on Maxeon\Sunpower technology, deliver more power per square metre, longer life and a deep-black aesthetic that surpasses standard Tough Black.

The performance is driven by 5D8 – the eighth generation of the Tough series’ five-dimensional technology evolution – where every layer, from the outer surface to the composite sandwich core and internal cabling, is optimized for high output and low losses, even in demanding marine environments. Shadow Optimized ensures more consistent and higher energy production under partial shading, while reducing long-term stress on the panels.

For a seamless design, Tough G8 Performance Black can be combined with Tough Black-Hole to cover irregular areas with one continuous deep-black surface. The panels are supplied without eyelets and are mounted using the included 3M tape and extra primer sheet for the cable protection. Together with the 5-year warranty, you get a clean installation and long-term peace of mind.

Flushed Soft Junction takes cable routing to the next level: an invisible, design-protected solution with an ultra-thin, UV-stable Flush cable and thick tinned conductors inside. The result is highe energy yield, minimal losses and extremely long service life in tough marine environments – without visible cabling spoiling the design.

Award-Winning Performance

Tough solar panels have repeatedly excelled in independent tests, proving their real-world performance—not just theoretical results.

Test Highlights:

  • Effective at high temperatures: Only a 13% power loss at 75°C compared to standard measurements at 25°C.
  • Highest power output: Best measured performance at a perpendicular angle, compared to other tested panels.
  • Durable and easy to use: “A walkable and robust flexible solar panel that’s easy to install thanks to the exceptionally well-designed cable connection.”

The Five-Dimensional Technological Evolution

The SUNBEAMsystem Tough series continues to lead with innovative technology. Five “dimensions” work together to create some of the most powerful, efficient and durable solar panels on the market

1. NEW G8 reinforced outer protection: SUNBEAMsystem’s unique surface technology with exceptional UV resistance and high transparency outperforms other “high-performance” coatings, such as ETFE.

2. Premium Maxeon (SunPower) cells: Higher efficiency (more watts per m²), broader light absorption, deep-black colour and longer service life.

3. Expandable, advanced and robust cabling: In-house developed internal cabling, both durable and expandable, ensures long-term performance.

4. UPGRADED G8 shock-absorbing layer: A robust material that protects the solar cells and cabling, improving durability and lifetime.

5. Lightweight composite sandwich core with high strength: A high-tech sandwich composite that protects the cells and offers near-metal mechanical properties – without the delamination risk seen in metal–plastic constructions.

Benefits of a rigid core

Soft panels wear out and lose performance more quickly due to the daily, repeated expansion and contraction that solar panels experience. Adding a metal plate is not a sustainable solution either, as differing expansion between metal and plastic leads to delamination.

With our unique sandwich composite – an integral part of 5D8 – we eliminate this problem and ensure superior durability.

Flushed Soft Junction

SUNBEAMsystem has been a pioneer in Soft Junction technology for more than ten years. The latest and most seamless design is unique and design-protected. The cabling has also been refined – the Flush cable can be glued on the outside or routed through a hole beneath the panel for a completely invisible, cable-free installation.

Advantages:

  • Up to 6% higher energy output
  • Discreet – truly cable-free installation
  • Eliminates wear from concentrated pressure on the panel
  • Extremely durable and stable under high loads
  • Prevents heat-induced deformation of the solar panel

Flush Cable Benefits:

  • Flexible install discreetly or completely hidden
  • UV-protected and tinned for maximum durability in marine environments
  • Low-loss core in a compact housing just 1.2 mm thick

Shadow Optimized

Tough G8 is equipped with SUNBEAMsystem’s unique Shadow Optimized technology, specially developed to improve panel performance under shading. This provides higher energy yield and better charging throughout the day.

On a traditional panel, even minor partial shading can stop charging completely – not only reducing output but also stressing the panel and shortening its lifespan. Shadow Optimized counteracts both of these issues, ensuring reliable charging and longer service life.

Comparison of Models and Solar Cells

We use only premium cells from Maxeon\Sunpower, which are top of the line and provide much better performance than Maxeon\Sunpower’s lower-cost alternatives. They are essential for enabling our solar panels to perform at the highest level. The table below compares different models (with explanations of each factor underneath in the original documentation).

Lifetime

Assesses how well the panel tolerates varying conditions, especially partial shading. High-quality Maxeon\Sunpower cells are less sensitive to such conditions and therefore achieve a longer lifespan. Combined with our unique Shadow Optimized technology, this results in significantly improved durability.

Efficiency

Directly linked to panel performance: higher efficiency means more energy from the same surface area.

Shadow Optimized Boost

Premium cells are designed to reduce heat build-up and power loss under shading. The higher the cell quality, the less heat is generated, which improves the effectiveness of our Shadow Optimized technology and increases total energy production – particularly important on boats and in motorhomes.

Aesthetics

For many users, the appearance of the cells matters. High-performance cells are characterised by a deep, uniform black colour.

Tough G8 Black-Hole Gap Filler

Custom solar styling for everyone

Tough G8 Black Hole is a favourite among premium boatyards as well as boat owners who want to give their boat a more luxurious and elegant look.

Give your solar installation a clean, unified appearance with Tough Black Hole. This DIY solution from SUNBEAMsystem lets anyone create a visually continuous solar surface – a sleek, black area that both enhances the aesthetics and helps maximize charging. A smart way to optimize both performance and appearance.

5-Year Warranty

SUNBEAMsystem uses advanced technology, high-quality solar cells and durable materials to create panels that can handle tough conditions. Tough panels come with a unique 5-year warranty* – unusually generous for light and thin solar panels.

Warranty handling and support are made easy via the Multi Connect app, which also offers remote control and online energy statistics for convenient monitoring and optimisation of your system.

*See the manual for full terms and registration requirements.

Tips for Maximizing Your Solar Panels’ Performance

  • Install the panels in unshaded locations and use multiple panels to cover larger surfaces.
  • Choose black panels if you want to combine them with our Tough Black-Hole solution – this not only improves the aesthetics but also makes it easier to utilise large areas.

For boats and motorhomes, parallel connection is recommended, as it offers the best performance and helps maintain panel lifetime. Use one or more MPPT charge regulators, such as Moonray, which are optimized to maximize the efficiency of parallel-connected panels (for both single panels and panel groups) – especially Moonray with Shadow Optimized – WeatherMAX technology.

This panel is designed for parallel connection. If, for any reason, you need a different setup, we recommend Moonray BOOST or our Tough-IQ panels.

Upgrading to SMART LITHIUM LiFePO4 batteries reduces energy losses during charging and discharging, providing a quick and effective upgrade to your electrical system.

All our smart products can be monitored and controlled via the Mobile Smart Home app, which includes a statistics view to help you optimize overall system efficiency.
