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

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

Make room for efficient solar charging with the CMPower 140 Watt Bifacial Rigid Solar Panel. Measuring 21.26" × 41.7" and weighing 14.77 lb, this compact panel offers a practical fit for boats, camper vans, RVs, and off-grid installations with limited mounting space.

Premium A+ Grade All-Back Contact (ABC) cells feature 27.4% cell conversion efficiency, helping you capture more energy within a compact footprint. The transparent backing allows reflected sunlight to reach the rear of the cells, creating opportunities for additional energy harvest when mounting conditions support bifacial performance.

Built with durable rigid glass-and-frame construction, this panel combines shade-tolerant technology with reduced heat-related power loss. A silver frame, IP67-rated junction box, and MC4 connectors complete a versatile panel for fixed solar installations.

Why Choose This 140W BC Bifacial Rigid Solar Panel?

✅ Compact Dimensions for Smaller Mounting Areas

The 21.26" × 41.7" footprint makes this panel worth considering for installations where larger panels would be difficult to accommodate. Use it as a single panel or incorporate multiple panels into a carefully planned array.

✅ Premium Back Contact Cells – 27.4% Cell Efficiency

All-Back Contact technology positions the electrical contacts behind each cell, leaving more of the front surface exposed to sunlight. This supports efficient energy capture while maintaining a clean cell appearance.

✅ Clear Backing for Bifacial Energy Capture

Generate electricity from sunlight reaching the front and reflected light reaching the rear. The transparent backing supports additional energy production when the underside remains exposed to suitable reflected light.

✅ Improved Performance Under Partial Shading

Advanced cell and electrical design helps improve performance when portions of the panel are shaded by rigging, antennas, mounting structures, or rooftop accessories.

✅ Reduced Output Loss in Warm Conditions

A −0.26%/°C maximum-power temperature coefficient helps limit the reduction in power as cell temperature rises—a useful advantage during sunny days on the water or at a campsite.

✅ Durable Construction at 14.77 lb

The rigid glass surface and supporting frame provide strength for securely mounted solar applications. At 14.77 lb (6.7 kg), this panel offers a manageable size and weight for installation planning.

✅ IP67 Junction Box and MC4 Connectors

An IP67-rated waterproof junction box and MC4 connections support integration with compatible solar wiring and charge controllers.
