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

Solar power without sacrificing usable space.

Turn smaller sections of your deck or roof into productive solar space with the CMPower 75 Watt Walkable Semi-Rigid Solar Panel. Its compact 14.2 × 35.8 inch footprint makes it an excellent choice for locations where larger solar panels simply won't fit.

Built with new-generation 27.4% efficient Back Contact solar cells, the panel combines high solar efficiency with a durable, supportive surface designed for walkable applications. Its semi-rigid construction is especially useful on boat decks, RV and van roofs, roof racks, and other space-constrained installations where preserving usable surface area is important.

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

At the heart of the panel are new-generation All-Back Contact (ABC) solar cells with 27.4% cell efficiency.
ABC technology moves the positive and negative electrical contacts to the rear side of the solar cell, leaving more of the front surface available for sunlight energy absorption.

For a compact solar panel, high cell efficiency is especially valuable. It allows the panel to produce 75 watts of rated power from a relatively small footprint, helping owners make productive use of installation areas that might otherwise remain unused.

The Back Contact design also gives the panel its distinctive clean, grid-free all-black appearance, making it well suited to installations where aesthetics matter.

Walkable Semi-Rigid Construction

Built for surfaces where usable space matters, the panel combines a walkable semi-rigid design with a twin-wall polycarbonate backing and J-channel mounting system.

• Polycarbonate Backing – Promotes airflow beneath the panel to help reduce heat buildup and protect the deck surface.
• J-Mount Channels – Secure the panel and backing while allowing them to slide into place for straightforward installation.

Better Performance When Partial Shade Happens

Perfect, uninterrupted sunlight isn't always realistic in marine and mobile installations.
On a boat, shadows from rigging, rails, antennas, masts, equipment, and other structures can move across a solar array throughout the day. Vans and RVs face similar challenges from roof accessories and nearby objects.

The CMPower 75W incorporates an advanced cell and electrical design intended to improve performance under partial shading, helping the panel make better use of available sunlight when part of its surface becomes shaded.

Designed to Perform in the Heat

Solar panels naturally lose some output as cell temperature increases, which makes temperature performance particularly relevant on sun-exposed boat decks and vehicle roofs.
The CMPower 75W features a Pmax temperature coefficient of -0.26%/°C, helping limit the reduction in maximum power as panel temperature rises.

Built for Marine & Mobile Environments

The CMPower 75W isn't simply a compact solar panel, it is designed around the realities of marine and mobile installations.
Its construction includes a waterproof IP67 XC503 single-entry junction box, 316 stainless steel mounting holes, and a black backsheet.

The panel has also undergone testing that includes IEC salt mist and high-temperature humidity conditions, important considerations for equipment intended for demanding outdoor and marine environments. The datasheet additionally lists CE, RoHS and SGS certification/testing.

Ideal for Boats, Vans & RVs

Ideal applications include:

• Boat decks and other marine surfaces
• Narrow or smaller deck areas
• Van and RV roofs
• Roof racks
• Areas around hatches and rooftop equipment
• Installations where walkable solar is desirable
• Space-constrained solar installations
