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

The CMPower 170W 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 170W Back Contact panel delivers 170 watts of maximum power from a panel measuring only:
540 × 1335 × 3 mm
21.26 × 52.56 × 0.12 in

With 27.4% efficient solar cells, the panel is designed to provide high solar output while maintaining a narrow 21.26-inch width.

This long, narrow format can be particularly useful on bimini tops, boat decks, RV and van roofs, and other installations where usable width is limited. It helps installers make efficient use of available mounting space while increasing installed solar capacity.

At only 3 mm thick, the CMPower 170W panel provides a low-profile alternative to conventional framed rigid solar modules.

Its semi-flexible construction makes it easier to accommodate suitable curved and weight-sensitive mounting surfaces commonly encountered on boats and mobile applications.

The datasheet specifies a maximum bend specification of 60°, allowing the panel to conform to compatible curved surfaces when properly installed.

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 particularly useful for marine installations where maintaining completely unobstructed sunlight throughout the day can be difficult.

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

The CMPower 170W Back Contact panel features a Pmax temperature coefficient of -0.26%/°C, helping reduce 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 170W output, semi-flexible construction, and a narrow 540 mm width makes this panel particularly attractive for bimini top solar installations.

Its 21.26 × 52.56 inch footprint provides a long, narrow form factor that can make efficient use of compatible bimini canvas and deck areas.

For boats with limited usable bimini or deck space, the 27.4% efficient Back Contact cells help maximize solar generation within the available installation area.

The panel's slim 3 mm profile also helps maintain a clean, unobtrusive installation compared with conventional framed solar modules.

The CMPower 170W 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.

According to the datasheet, 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 XC502 junction box, these features provide a practical foundation for professional marine, RV, van, and mobile solar installations.
