Product Details
Power your adventures and off-grid systems with the Victron Energy BlueSolar 285W Monocrystalline Solar Panel (SPM042855603). This high-performance module is engineered to provide consistent, reliable electricity for solar arrays where space and efficiency are top priorities.
With a market-leading 20.89% efficiency rating, this 56-cell panel captures more energy per square inch, making it ideal for limited roof space on vehicles or boats. The module features an advanced EVA (Ethylene Vinyl Acetate) encapsulation system with a triple-layer back sheet, ensuring it meets the most stringent safety requirements for high-voltage operation.
Built to last, the panel is encased in a sturdy, anodized aluminium frame for easy mounting and the highest quality, high-transmission tempered glass for superior impact resistance against hail and harsh weather. Installation is a breeze thanks to the pre-wired quick-connect system using industry-standard MC4 connectors.
