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

Turn narrow mounting areas into productive solar space with the CMPower 190 Watt Bifacial Rigid Solar Panel. Measuring just 21.26" wide × 56.9" long, this panel offers an efficient solution for boats, camper vans, and RVs where fitting panels around existing equipment takes careful planning.

Premium A+ Grade All-Back Contact (ABC) cells feature 27.4% cell conversion efficiency, while the transparent backing allows reflected sunlight to reach the rear of the cells. This bifacial design can increase energy harvest when the installation provides suitable rear-side light exposure.

Shade-tolerant technology and a −0.26%/°C power temperature coefficient support performance in changing sunlight and warm conditions. Durable rigid glass-and-frame construction, an IP67-rated junction box, and MC4 connectors make this panel a practical choice for fixed marine, vehicle, and off-grid solar installations.

Why Choose This 190W BC Bifacial Rigid Solar Panel?

✅ Slim Profile for Space-Conscious Installations

The 21.26" × 56.9" footprint provides an option for long, narrow mounting areas that may not accommodate wider panels. Use it individually or as part of an array designed around your available space.

✅ Premium Back Contact Cells – 27.4% Cell Efficiency

ABC solar cells place the positive and negative electrical contacts on the rear, leaving more of the front surface exposed to sunlight. This design supports efficient energy capture and a clean cell appearance.

✅ Bifacial Design with Clear Backing

The transparent rear backing allows reflected light to contribute to electricity generation. Installations with an exposed underside and reflective surroundings can benefit from additional energy production.

✅ Improved Partial-Shade Performance

Advanced cell and electrical design helps improve performance when portions of the panel are shaded. This is useful around boat rigging, antennas, davits, and rooftop accessories that cast moving shadows.

✅ Reduced Heat-Related Output Loss

The −0.26%/°C maximum-power temperature coefficient helps limit the decline in power as cell temperature rises—an advantage during sunny days on the water or at an off-grid campsite.

✅ Durable Construction at 20.06 lb

A rigid glass surface and silver frame provide strength for securely supported installations. The panel weighs 20.06 lb (9.1 kg) and is designed for flat mounting.

✅ IP67 Junction Box and MC4 Connectors

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