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

Add efficient solar charging to narrower mounting spaces with the CMPower 245 Watt Bifacial Rigid Solar Panel. Featuring new-generation A+ Grade Back Contact cells with 27.4% cell conversion efficiency, this panel delivers 245 watts of rated power in a 26.8" × 56.9" footprint, a practical option for marine, van, and off-grid installations where available width is limited.

The clear backing enables reflected sunlight to reach the rear of the cells, creating opportunities for additional energy harvest when installation conditions support bifacial gain. Shade-tolerant cell and electrical design also helps improve performance when rigging, antennas, or other equipment partially obstruct sunlight.

With durable rigid glass-and-frame construction, a silver frame, and an IP67-rated junction box, this panel is suited to fixed installations on arches, dinghy davits, poles, and compatible rooftop mounting systems.

Why Choose This 245W BC Bifacial Solar Panel?

✅ High-Efficiency Back Contact Cells

The 27.4% efficient cells help make productive use of valuable mounting space. All-Back Contact (ABC) technology places electrical contacts behind each cell, exposing more of the front surface to sunlight while maintaining a clean appearance.

✅ Bifacial Design with Transparent Backing

Capture sunlight from the front and reflected light reaching the rear. The clear backing supports additional energy production when the underside is exposed to suitable reflected light.

✅ Shade-Tolerant Technology

Advanced cell and electrical design improves performance under partial shading. This is particularly useful on boats and RVs, where nearby structures and equipment can cast changing shadows throughout the day.

✅ Reduced Heat-Related Power Loss

A −0.26%/°C maximum-power temperature coefficient helps limit output losses as cell temperature increases, supporting solar generation in warm operating conditions.

✅ Narrow 26.8-Inch Profile

Measuring 26.8" wide × 56.9" long, this panel offers flexibility when laying out an array around restricted mounting areas. Its dimensions make it worth considering for installations where wider panels may be difficult to accommodate.

✅ Durable Rigid Glass Construction

The robust glass-and-frame design provides strength for permanent mounting applications. Each panel weighs 25.79 lb (11.7 kg) and is designed for flat, securely supported installation.

✅ IP67 Junction Box and MC4 Connectors

An IP67-rated waterproof junction box, 4.0 mm² cables, and MC4 connectors support integration with compatible solar wiring and charging equipment.
