The Canadian Solar HiHero+ 645W Bifacial HJT Solar Panel is a premium high-power solar module designed for maximum energy yield, excellent bifacial gain, and long-term reliability. With 645W output, 23.9% module efficiency, N-Type HJT technology, and dual-glass durability, it is ideal for commercial, industrial, and large-scale solar projects.

The Canadian Solar HiHero+ 645W Bifacial HJT Solar Panel is the highest-power model in the HiHero+ CS6.2-66HB series, delivering 645W nominal power with up to 23.9% module efficiency. Built with advanced Bifacial N-Type Heterojunction Technology, this module can generate electricity from both the front and rear sides, increasing total energy production depending on mounting height, tilt angle, installation structure, and ground reflectivity.

This panel offers excellent hot-climate performance with a leading temperature coefficient of -0.24%/°C, helping maintain stronger output in high-temperature environments. Its HJT cell technology provides low degradation, no B-O LID, and strong anti-LeTID and anti-PID performance, supporting stable energy production over time.

The module uses a durable dual-glass structure with 2.0 mm front heat-strengthened glass and 2.0 mm back glass, combined with an anodized aluminium alloy frame and IP68 junction box. It is engineered to handle heavy snow loads up to 5400 Pa and wind loads up to 2400 Pa, making it suitable for demanding outdoor solar installations.

Canadian Solar provides a 15-year product warranty and a 30-year linear power performance warranty for this series, with first-year degradation no more than 1% and annual degradation after the first year no more than 0.3%.
