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

Bring efficient solar charging to your boat, van, or off-grid system with the CMPower 270 Watt Bifacial Rigid Solar Panel. Featuring premium A+ Grade Back Contact cells with 27.4% cell conversion efficiency, this new-generation panel combines a space-conscious footprint with shade-tolerant technology and rear-side light capture.

At 30" × 56.3", the panel offers a practical fit for mounting areas where width matters. Its transparent backing allows reflected sunlight to reach the rear of the cells, supplementing front-side energy production under suitable installation conditions.

Built with durable rigid glass-and-frame construction, a silver frame, and an IP67-rated junction box, this 270W solar panel is suited to marine arches, dinghy davits, pole mounts, RVs, and fixed off-grid installations.

Why Choose This 270W BC Bifacial Solar Panel?

✅ Premium Back Contact Cells – 27.4% Cell Efficiency

All-Back Contact (ABC) technology moves the electrical contacts to the rear of each cell, leaving more of the front surface exposed to sunlight. The result is efficient light capture and a clean solar cell appearance.

✅ Bifacial Energy Capture with Clear Backing

Generate electricity from direct sunlight on the front and reflected light reaching the rear. The transparent backing supports additional energy harvest when the panel’s underside remains exposed to suitable reflected light.

✅ Shade-Tolerant Performance

Advanced cell and electrical design improves performance under partial shading, a useful advantage around sailboat rigging, antennas, arch structures, and rooftop accessories.

✅ Strong Performance in Warm Conditions

A −0.26%/°C power temperature coefficient helps limit the reduction in output as cell temperature rises. This supports energy production during hot days on the water or at an off-grid campsite.

✅ A Practical 30-Inch-Wide Footprint

The 30" × 56.3" dimensions give you another option when planning around narrower mounting areas. High-efficiency cells help make productive use of the space available for your solar array.

✅ Durable Construction for Fixed Installations

The rigid glass surface and supporting frame provide lasting strength for securely mounted solar systems. At 28.44 lb (12.9 kg), the panel can be incorporated into appropriately designed marine, vehicle, or stationary mounting structures.

✅ IP67 Junction Box and MC4 Connectors

An IP67-rated waterproof junction box and MC4 connectors provide a convenient connection system for integration with compatible solar wiring and charging equipment.
