The SUNBEAMsystem Tough 78W Flush - Black solar panel is part of the premium line of SUNBEAMsystem. The panel is equipped with Sunpower Maxeon cells with an efficiency of 22.5% or higher. As a result, the size of the panel is only 77.8 x 54 cm and the panel has a power of 78 watts.
The SUNBEAMsystem Tough Black series has been designed to look both inconspicuous and elegant at the same time. Developed with the intention to integrate perfectly in the looks of both modern yachts and historical ships. Best suited for applications that put an emphasis on aesthetics: Tough Black pleases both the eye as well as your battery level.
With their dark appearance, the Tough Black panels will blend in on any even colored background. Whether this background is pure white or a classic brown: nobody will suspect there’s a solar panel hidden behind the all-black surface. For a truly seamless surface integration, you can use the Tough Black Hole filler. An identical material without any cells that can be cut to size to fill up any irregular shapes surrounding the panels.
The Tough Black series provides you with the same advantages as the normal Tough series. For installation, we advise black flexible glue like Sikaflex 291i.
In 2021, all Flush models will be equipped with an improved cable connection on the back of the panels. All Tough models are also equipped with stronger cell protection, for an even longer lifespan.
