TOUGH G8 21W

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 – without moving up to the Performance level.

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 performance is built on 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.

A key improvement with the G8 generation is that Tough G8 now ships with full-size 3M VHB tape. The included VHB tape enables a quick, clean installation and helps extend the panel’s lifetime by allowing controlled expansion. The tape is supplied separately, so you can choose an approved specialist adhesive instead, as long as you carefully follow the instructions in the manual.
