85 Watt Walkable Semi Rigid Solar Panel with Polycarbonate & J-Mount Brackets - New Generation Back Contact Cell A+ Grade 27.4% Efficient Cells

Get more solar power from limited roof or deck space with the CMPower 85 Watt Walkable Semi-Rigid Solar Panel. Built with high-efficiency 27.4% Back Contact solar cells, this new-generation panel combines a sleek all-black appearance, durable semi-rigid construction, and a walkable surface designed for demanding marine and mobile applications.

At just 11.4 × 48 inches (290 × 1220 mm), the long, narrow profile makes it easier to use available spaces on boat decks, van roofs, racks, and other installations where conventional solar panels may not fit. The semi-rigid construction provides a tougher, more supportive solar surface while helping preserve usable space.

What's Included:

• PV solar panel module
• Sheet of twin wall polycarbonate backing
• Two J channel mounting extrusions
• Owner’s Manual

27.4% High-Efficiency Back Contact Cells

The panel uses advanced All-Back Contact (ABC) solar cells, with all positive and negative electrical contacts positioned on the rear side of the cell. This maximizes the front surface available for sunlight energy absorption and creates a clean, grid-free all-black appearance.

With 27.4% cell efficiency, this panel is designed to deliver more power from a relatively small installation footprint, especially useful when available solar space is limited.

Enhanced Shade Tolerance

The advanced cell and electrical design provides enhanced performance under partial shading. Each solar cell is designed with a bypass diode to help reduce the impact of shading on the panel's output.

This makes the panel particularly well suited to real-world installations where shadows from rigging, rails, equipment, roof accessories, or other objects may cross part of the solar array.

Excellent High-Temperature Performance

The panel is designed for stable operation in demanding outdoor environments, with a Pmax temperature coefficient of -0.26%/°C. This helps reduce power losses as panel temperature rises. The specified operating temperature range is -40°C to +85°C.

Ideal for Marine, Van & RV Applications

Designed for demanding solar applications, this panel is well suited for:

• Boat decks and other marine applications
• Van and RV roofs
• Roof racks
• Areas where walkable solar is desirable
• Installations with limited available solar space
• Applications where a long, narrow panel profile is useful

Solar power without sacrificing usable space.
