The Canadian Solar HiHero+ 640W Bifacial HJT Solar Panel is built with advanced Bifacial N-Type Heterojunction Technology, allowing the panel to generate electricity from both the front and rear sides. This bifacial design can increase total energy yield depending on installation height, mounting structure, tilt angle, and ground reflection.
This model delivers 640W nominal power with 23.7% module efficiency, making it a strong choice for high-performance solar installations. Its HJT cell technology provides excellent low-degradation performance, with no B-O LID and strong anti-LeTID and anti-PID resistance.
The panel also features a leading temperature coefficient of -0.24%/°C, helping maintain better output in hot climate conditions. With dual-glass construction, anodized aluminium alloy frame, IP68 junction box, and strong mechanical load capacity, the module is designed for durable outdoor operation.
Canadian Solar supports this panel with a 15-year product warranty and a 30-year linear power performance warranty. The module is designed for professional solar systems requiring high efficiency, bifacial power gain, and dependable long-term energy generation.
