170 Watt Bifacial Rigid Solar Panel with Clear Backing - New Generation Back Contact Cell A+ Grade 27.4% Efficient Cells

170 Watt Bifacial Rigid Solar Panel with Clear Backing - New Generation Back Contact Cell A+ Grade 27.4% Efficient Cells

Build an efficient solar charging system around your available space with the CMPower 170 Watt Bifacial Rigid Solar Panel. Its compact rectangular design makes it a practical option for boats, camper vans, RVs, and off-grid installations where larger panels can be difficult to position.

Featuring premium A+ Grade All-Back Contact (ABC) cells with 27.4% cell conversion efficiency, this panel combines efficient front-side energy capture with transparent backing that allows reflected sunlight to reach the rear of the cells. Under suitable mounting conditions, this bifacial construction can increase overall energy harvest.

Shade-tolerant cell and electrical design helps improve performance under partial shading, while a −0.26%/°C power temperature coefficient helps reduce heat-related output losses. Durable glass-and-frame construction, a silver frame, and an IP67-rated junction box complete a panel designed for demanding solar applications.

Why Choose This 170W BC Bifacial Rigid Solar Panel?

✅ Compact Size for Versatile Mounting

With dimensions of 675 × 1060 × 30 mm and a weight of 18.08 lb, this panel offers flexibility when planning solar around deck equipment, rooftop accessories, or limited mounting areas.

✅ Premium Back Contact Cells – 27.4% Cell Efficiency

All-Back Contact technology places both positive and negative electrical contacts on the rear of each cell. This exposes more of the front surface to sunlight, supporting efficient energy capture and a clean appearance.

✅ Bifacial Design with Clear Backing

Capture direct sunlight from the front and reflected light reaching the rear. The transparent backing creates opportunities for additional energy production when the underside remains exposed to suitable reflected light.

✅ Improved Partial-Shade Performance

Advanced cell and electrical design helps improve performance when shadows fall across portions of the panel. This is useful around sailboat rigging, antennas, davits, and other equipment that can interrupt direct sunlight.

✅ Reduced Power Loss in Hot Conditions

A −0.26%/°C maximum-power temperature coefficient helps limit output reductions as cell temperature rises, supporting energy production during warm-weather cruising and camping.

✅ Durable Rigid Glass Construction

The robust glass-and-frame assembly provides strength for fixed mounting applications. Designed to remain flat, the panel can be installed on appropriately supported marine, vehicle, or stationary mounting structures.

✅ IP67 Junction Box and MC4 Connections

An IP67-rated waterproof junction box and MC4 connectors support connection to compatible solar wiring and charging equipment.
