TOUGH BLACK 21W LONG
For over a decade, SUNBEAMsystem has been driving solar panel innovation with cutting-edge solutions. Drawing on our Swedish heritage and extensive experience with boating applications, we design products that suit real-world needs. This commitment shines through in our latest update, which combines new technologies into a single panel. The Tough series is only surpassed by our more advanced models carrying a “plus” in their name.
Tough Black panels are available in both eyelet and non-eyelet versions and should be installed with a soft, flexible adherent that follows the supporting surface without creating an overly rigid bond (see the manual for recommended types).
For a quicker and more reliable result, we recommend any Tough series panel with a “plus” in the name. These models include a full-size 3M double-sided adhesive film, allowing for the sometimes significant expansion of the panel.
High Efficiency: 22.6% efficiency
5D-evo: Part of the Tough series’ five-dimensional technology evolution
Shadow Optimized: Enhanced shading performance

Solar panels need a charge controller!
