For more than a decade, SUNBEAMsystem has driven the development of marine solar panels with a clear focus on real-life use on board. Tough G8 is the core model for anyone who wants high efficiency, long service life, and a clean, premium look – and it’s also available in an IQ version for users who want added built-in intelligence.

With 22.6% efficiency, Tough G8 delivers a lot of power per square metre, building on high-quality Maxeon\Sunpower cell technology. Compared with simpler black panels, you get both more energy and a more uniform deep-black surface that really elevates the look of your boat.

The core is the 5D8 – the eighth generation of the Tough series’ five-dimensional technology evolution – where every layer, from the new G8 surface to the composite sandwich core and internal cabling, is optimized for high output, low losses, and long life in demanding marine environments. At the same time, Shadow Optimized ensures the panel continues to deliver energy even under partial shading, while reducing long-term stress on the cells.

In the IQ version, integrated microprocessor-based functions add an extra layer of protection and optimization at panel level. The result is more stable energy production in changing on-board conditions — without changing the Tough design or installation approach.
