440 Watt Bifacial Rigid Solar Panel with Clear Backing - New Generation Back Contact Cell A+ Grade 27.9% Efficient Cells

This 440 Watt Bifacial Rigid Solar Panel features premium Back Contact (BC) solar cell technology with an impressive 27.9% cell efficiency, delivering exceptional power output from a compact footprint. Designed specifically for demanding marine and mobile applications, this panel performs exceptionally well in both full sun and partial shading conditions.

The clear backing allows the panel to capture reflected light from the rear side, increasing energy harvest in suitable installations while maintaining the sleek appearance of back contact cells with no visible front busbars.

Built to withstand harsh marine environments, this panel is ideal for boats, sailboats, trawlers, catamarans, vans, expedition vehicles, and off-grid systems where maximizing power production per square foot is essential.

Why Choose This 440W BC Bifacial Solar Panel?

✅ Premium Back Contact Solar Cells – 27.9% Efficient

One of the highest-efficiency solar cell technologies available today. Generate more power from limited mounting space compared to conventional panels.

✅ Bifacial Design with Clear Backing

The transparent backing allows the panel to utilize reflected light from the rear side, helping boost energy production in the right installation conditions.

✅ Advanced Shade-Tolerant Technology

Designed to maintain strong performance even when portions of the panel experience shading from rigging, radar domes, antennas, booms, or other onboard equipment.

✅ More Power Per Square Foot

Produce significantly more energy from the same deck, arch, davit, or rooftop space compared to traditional residential solar panels.

✅ Superior Low-Light Performance

Back contact cells deliver excellent energy production during cloudy conditions, early mornings, and late afternoons.

✅ Marine-Ready Construction

Features a durable anodized aluminum frame, IP67-rated junction box, MC4 connectors, and rugged construction designed to withstand harsh environments.

✅ Precision Automated Manufacturing

Fully automated welding creates solid electrical connections for improved durability and consistent performance.
