Built with new-generation All-Back Contact (ABC) solar cells featuring 27.4% cell conversion efficiency, this rigid glass panel combines efficient energy capture, shade-tolerant performance, and transparent backing for marine, van, and off-grid installations. Measuring 36.2" × 56.9", this panel provides 325 watts of rated power in a versatile rectangular footprint. Its clear backing allows reflected sunlight to reach the rear of the cells, creating opportunities for additional energy production when the mounting position and surrounding surfaces support bifacial gain. From sailboat arches and dinghy davits to van mounting systems, the durable glass-and-frame construction offers a practical solution for dependable solar charging. An IP67-rated junction box and MC4 connectors complete the panel’s electrical connection system. Why Choose This 325W BC Bifacial Solar Panel? ✅ A+ Grade Back Contact Cells – 27.4% Cell Efficiency All-Back Contact technology places the positive and negative electrical contacts on the rear of each cell, leaving more of the front surface exposed to sunlight. This design supports efficient energy capture and gives the panel a clean, streamlined appearance. ✅ Clear Backing for Additional Rear-Side Energy Capture The transparent backing allows the panel to collect reflected light from behind the cells. Installations with an exposed rear surface and suitable reflected light can benefit from additional energy harvest. ✅ Improved Performance Under Partial Shading Advanced cell and electrical design helps reduce the impact of partial shading from rigging, antennas, davits, or rooftop equipment. This makes the panel well suited to installations where unobstructed sunlight is difficult to maintain throughout the day. ✅ Reduced Power Loss in Hot Conditions With a −0.26%/°C maximum-power temperature coefficient, this panel helps limit heat-related power losses as cell temperature rises—an advantage for sunny marine and RV environments. ✅ Efficient Use of Available Mounting Space High-efficiency cells help maximize solar generation within the panel’s 36.2" × 56.9" footprint. Use the dimensions to plan a single-panel installation or a multi-panel array around your vessel’s or vehicle’s available space. ✅ Durable Rigid Glass Construction A rigid glass surface and silver frame provide structural strength for fixed mounting applications. The panel weighs 34.39 lb (15.6 kg) and is designed to remain flat.

An elevated installation with an exposed underside can offer better opportunities for bifacial gain than mounting directly against an opaque surface. For the best results: Keep the rear surface exposed to reflected light where practical. Consider the reflectivity of nearby surfaces when choosing a mounting location. Use mounting hardware appropriate for the panel’s dimensions, weight, and installation environment.
