155 Watt Flexible Marine Solar Panel - New Generation Back Contact Cell A+ Grade 27.4% Efficient Cells

The CMPower 155W panel uses 27.4% efficient Back Contact solar cells, representing a new generation of high-efficiency photovoltaic technology.

Unlike conventional solar cells with electrical contacts on the front surface, ABC (All-Back Contact) technology places all positive and negative electrical contacts on the rear side of the cell. This leaves more of the front surface unobstructed and available for sunlight energy absorption.

The design also creates a clean, seamless, grid-free appearance, giving the panel a sleek all-black finish particularly suited to premium marine, yacht, RV, and van installations.

When mounting space is limited, panel efficiency becomes increasingly important.

The CMPower 155W Back Contact panel delivers 155 watts of maximum power from a panel measuring only:

540 × 1210 × 3 mm
21.26 × 47.64 × 0.12 in

With 27.4% efficient solar cells, the panel is designed to provide high power output from a relatively narrow installation footprint.

Its 21.26-inch width makes it especially useful where available mounting width is constrained, while the longer panel format provides 155W of rated output.

For boats, RVs, vans, and other mobile installations with limited usable space, this combination can help maximize installed solar capacity without requiring a conventional framed module.

Despite its 155W power rating, the CMPower panel weighs only 2.1 kg (4.63 lb).

Its lightweight construction minimizes additional load on bimini frames, boat structures, van roofs, RV roofs, and other weight-sensitive surfaces.

At just 3 mm thick, the panel also maintains a low-profile installation compared with conventional framed rigid solar modules.

The semi-flexible construction allows installation on suitable curved surfaces, with the datasheet specifying a maximum bend specification of 60°.

Note: This is a semi-flexible solar panel and should only be bent within the manufacturer's specified limits.

Marine and mobile solar installations frequently experience changing or partial shading caused by:

• Masts
• Rigging
• Antennas
• Rails
• Radar equipment
• Bimini hardware
• Roof accessories
• Other nearby structures

The CMPower Back Contact panel incorporates an advanced cell and electrical design intended to improve performance under partial shading, helping make better use of available sunlight in real-world conditions.

This makes it especially useful for marine installations where maintaining completely unobstructed sunlight throughout the day is often difficult.

Solar panel output normally decreases as cell temperature increases, making temperature performance especially relevant for panels exposed to direct sunlight on boat decks, bimini tops, vans, RVs, and rooftops.

The CMPower 155W Back Contact panel features a Pmax temperature coefficient of -0.26%/°C, helping limit power loss as panel temperature rises.

Its temperature characteristics are:

• Pmax: -0.26%/°C
• Voc: -0.24%/°C
• Isc: +0.05%/°C
• Operating Temperature: -40°C to +85°C

The combination of 155W output, lightweight construction, semi-flexible design, and a narrow 540 mm width makes this panel particularly attractive for bimini top solar installations.

Its 21.26 × 47.64 inch footprint allows installers to arrange panels across compatible bimini structures while making efficient use of available canvas area.

At only 4.63 lb per panel, it also adds significantly less weight than many conventional framed solar modules.

For boats with limited usable bimini or deck space, the high-efficiency Back Contact cells help maximize solar generation within the available installation area.

The CMPower 155W semi-flexible solar panel is designed for real-world installations including:

Boats • Bimini Tops • Boat Decks • Yachts • Sailboats • Vans • RVs • Roof Racks • Rooftops • Curved Surfaces

Its marine-oriented construction includes a waterproof IP67 XC502 junction box, 316 stainless steel mounting holes and eyelets, and testing that includes IEC salt mist and high-temperature humidity conditions.

The black backsheet and all-black Back Contact cell design also provide a clean finished appearance suitable for installations where aesthetics are important.

The panel is supplied with six mounting holes/eyelets manufactured from 316 stainless steel, a corrosion-resistant material well suited to demanding marine environments. The grommets are positioned approximately 14 mm from the panel edge.

Electrical connection is provided through:
0.9 m solar cable • 4 mm² conductor • MC4 connectors

Combined with the IP67 waterproof junction box, these features provide a practical foundation for professional marine, RV, van, and mobile solar installations.
