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

This 550 Watt Bifacial Rigid Solar Panel utilizes premium Back Contact (BC) solar cell technology with an industry-leading 27.4% cell efficiency to deliver exceptional energy production in a durable, marine-ready package. Featuring a transparent backing and Shade-Tolerant design, this panel is designed to maximize power output in real-world conditions where partial shading and limited installation space are common.

The bifacial construction allows the panel to capture reflected light from the rear side, increasing energy harvest when installed over reflective surfaces. Combined with the sleek appearance of back contact cells and outstanding low-light performance, this panel is an excellent choice for larger marine, camper van, and off-grid energy systems.

Built with a rugged anodized aluminum frame, IP67-rated junction box, and automated precision manufacturing, this panel is engineered to provide years of reliable service in harsh environments.
