325 Watt Walkable Semi-Rigid Solar Panel - Carbon Fiber Series - Sunpower A+ Grade 24.4% Efficient Cells

Power your adventures with the 325 Watt Walkable Carbon Fiber Semi-Rigid Solar Panel — the ultimate combination of durability, performance, and cutting-edge solar technology.

Built with SunPower A+ Grade Maxeon solar cells rated at 24.4% efficiency, this marine- and RV-grade solar panel delivers superior output and reliability in any environment. 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.

The advanced carbon fiber backing provides exceptional rigidity (slight bending is possible), impact resistance, and heat dissipation, while a thick ETFE top laminate protects against UV damage, saltwater, and heavy foot traffic. Whether installed on a boat deck, van roof, dock, or RV, this walkable semi-rigid panel stands up to the toughest conditions while delivering maximum off-grid power.

Engineered for high-demand marine and mobile energy systems, this is the ideal solution for sailors, overlanders, and liveaboards who need dependable, high-efficiency solar power that lasts.

Drill your own holes if needed in the 4 marked spots. Use the J and H channels or custom 'washers' for mounting.

✅ Six foot long #10 duplex cable from the junction box included.
📦 Ships in 1-2 business days with UPS Ground from Denver.

⚡ Key Features

• High Power Output – Generates 325 watts of clean energy using SunPower A+ Grade Maxeon cells with 24.4% efficiency — the highest commercially available.

• Walkable Carbon Fiber Design – Reinforced carbon fiber backing offers rigidity, impact resistance, and the ability to safely walk on the panel.

• 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.
  

• Superior Heat Dissipation – Carbon fiber base helps regulate panel temperature for optimal efficiency and longevity.

• ETFE Protective Laminate – Thick, UV-stable ETFE coating resists scratches, corrosion, and degradation from sun and salt exposure.

• Marine & RV Ready – Perfect for boats, vans, RVs, campers, docks, and off-grid installations.

• Warranty & Support – Covered by a 5-year manufacturer warranty from Custom Marine Products.
