Canadian Solar HiHero CS6.2-66HB-640H 640W Bifacial HJT Low Carbon Solar Panel

The Canadian Solar HiHero 640W (CS6.2-66HB-640H) is a bifacial heterojunction (HJT) solar panel from the Canadian Solar Low Carbon HiHero series, built for commercial, industrial, and utility-scale projects. It delivers 640W of front-side power at 23.7% module efficiency from 132 HJT cells in a 2 × (11 × 6) layout, with 2.0 mm heat strengthened glass on both faces and an anodized aluminium alloy frame.

According to the datasheet, the Canadian Solar HiHero 640W is assembled in the US from local cells and imported components, and it is positioned as a low carbon module with lower energy consumption, lower carbon emissions, and a shorter carbon payback time.

Canadian Solar Inc. is a BNEF Tier 1 and S&P Global Tier 1 module manufacturer and a leading provider of integrated solar and energy storage solutions. With over 24 years of expertise, the company has delivered more than 165 GW of solar modules worldwide. Its management systems are certified to ISO 9001:2015 (quality), ISO 14001:2015 (environment), and ISO 45001:2018 (occupational health and safety).
