120 Watt Walkable Solar Panel – SunPower A+ Grade 24.4% Efficiency
Upgrade your off-grid power setup with the 120 Watt Walkable Solar Panel, engineered with premium SunPower A+ grade Maxeon cells for unmatched durability and performance. Designed to withstand heavy use on boat decks, van roofs, docks, and other rugged surfaces, this semi-rigid marine solar panel combines strength, flexibility, and industry-leading efficiency.
With an impressive 24.4% cell efficiency, this panel delivers more energy over the course of the day, even in partial shade or low sun angles - outperforming standard solar panels. Built with an ETFE laminate coating, it resists saltwater, UV exposure, and the toughest marine conditions, ensuring long-lasting performance wherever your adventures take you.

Key Features:
-
120W High-Efficiency Output – A+ grade Sunpower Maxeon cells produce relatively high amounts of power even at low sun angles, thus generating more watt-hours over the course of a day than lower quality panels.
-
Walkable & Semi-Rigid Design – Built tough for sailboats and vans applications, strong enough to take foot traffic.
-
Superior Low-Light Performance – Produces power even in partial shade or at low sun angles. Each cell works when partially shaded unlike most other solar cells where the whole panel will go down if a portion of a cell is shaded.
-
ETFE Laminated – Further protect the A+ grade solar cells, the highest efficiency cells commercially available.
-
Easy Installation – Includes six foot long #10 duplex cable from the junction box; mount via 4 pre-marked drill spots, J and H channels, or custom 'washers'.
-
Versatile Use – Excellent for boat decks, van roofs, docks, anywhere a solar panel needs to be able to take abuse.
- Curved-Surface Compatible – Has some rigidity though can curve some as well.
This walkable solar panel is not only rugged but also smartly engineered to keep generating energy when other panels fail. Whether you’re powering up on open water or camping off-grid, it delivers reliable solar power without compromise.
