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

Put compact mounting space to work with the CMPower 210 Watt Bifacial Rigid Solar Panel. Its nearly square 36.2" × 37" footprint offers a useful alternative to longer rectangular panels when planning solar installations on boats, camper vans, RVs, and off-grid structures.

New-generation A+ Grade All-Back Contact (ABC) cells feature 27.4% cell conversion efficiency, helping maximize energy capture within the available panel area. Transparent backing allows reflected sunlight to reach the rear of the cells, supporting additional energy production under suitable installation conditions.

Combining shade-tolerant technology, reduced heat-related power loss, and durable glass-and-frame construction, this 210W panel is designed for demanding solar applications. A silver frame, IP67-rated junction box, and MC4 connectors complete the assembly.

Why Choose This 210W BC Bifacial Rigid Solar Panel?

✅ Nearly Square Footprint for Flexible Layouts

At 36.2" × 37", this panel gives you another way to arrange solar around your available mounting area. Its shorter overall length can be useful where a long rectangular panel would be difficult to accommodate.

✅ Premium Back Contact Cells – 27.4% Cell Efficiency

ABC technology positions both positive and negative electrical contacts on the rear of each cell. This leaves more of the front surface exposed to sunlight for efficient energy capture and a clean appearance.

✅ Clear Backing for Bifacial Energy Harvest

The panel generates electricity from front-side sunlight and reflected light reaching the rear. An exposed underside and reflective surroundings can help increase overall energy harvest.

✅ Improved Performance Under Partial Shading

Advanced cell and electrical design helps improve output under partial shading from rigging, antennas, mounting structures, and rooftop equipment. This is a practical benefit for installations where shadows move across the panel throughout the day.

✅ Reduced Power Loss as Temperatures Rise

The −0.26%/°C maximum-power temperature coefficient helps limit heat-related reductions in output, supporting solar production in warm marine, RV, and off-grid environments.

✅ Durable Rigid Glass-and-Frame Construction

Built for securely supported, fixed installations, the panel combines a rigid glass surface with a silver frame. It weighs 22.27 lb (10.1 kg) and is designed to remain flat.

✅ IP67 Junction Box and MC4 Connections

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