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

The CMPower 90W panel uses 27.4% efficient Back Contact solar cells, representing a new generation of high-efficiency photovoltaic technology.

Unlike conventional solar cell designs, ABC (All-Back Contact) technology places all positive and negative electrical contacts on the rear side of the cell. This allows more of the front surface to remain available for sunlight energy absorption while creating a clean, seamless appearance without the prominent front-side grid pattern found on many conventional solar panels.

The result is a high-efficiency solar panel designed to provide more power from limited installation space while maintaining a sleek all-black finish.

When available roof, deck, or bimini space is limited, solar panel efficiency becomes especially important.

At 27.4% cell efficiency, the CMPower 90W panel is designed to deliver high output from its compact 540 × 705 mm (21.26 × 27.75 inch) footprint.

Its 90W output makes it particularly well suited for applications where maximizing solar generation within a limited mounting area is important, including boat bimini tops, boat decks, marine and yacht installations, van roofs, roof racks, rooftops, and other curved or weight-sensitive surfaces.

At only 1.6 kg (3.53 lb) and approximately 3 mm thick, the CMPower 90W panel provides substantial solar output without the weight and bulk associated with many conventional rigid panels.

Its semi-flexible construction allows the panel to conform to suitable curved mounting surfaces. The datasheet specifies a 60° maximum bend specification, making it suitable for carefully designed curved installations while maintaining a low-profile appearance.

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

Marine and mobile solar installations are frequently exposed to partial shading caused by masts, rigging, antennas, rails, rooftop equipment, and other obstructions.

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

The panel also features a -0.26%/°C Pmax temperature coefficient, helping reduce power loss as cell temperature increases.

The 90W model provides a larger power output than smaller-format flexible panels while maintaining a relatively compact 21.26 × 27.75 inch footprint.

This makes it particularly useful for bimini installations where the goal is to generate more solar energy without occupying excessive canvas or deck area.

The panel's lightweight construction also helps minimize additional weight on bimini structures and other weight-sensitive mounting locations.

Solar panels naturally lose some output as cell temperature rises.

The CMPower 90W Back Contact panel has a Pmax temperature coefficient of -0.26%/°C, along with a Voc coefficient of -0.24%/°C and Isc coefficient of +0.05%/°C.

Its operating temperature range is specified from -40°C to +85°C, supporting use across a wide range of environmental conditions.
