Key information for this model.
Use the verified specifications below as a research starting point, then confirm the exact regional version on the manufacturer page before buying.
Where it fits.
Commercial and utility systems where bifacial energy gain can be supported by the mounting geometry and ground/roof reflectance, and where the exact 620H module is certified and available for the project market.
Limits to check.
Real bifacial gain depends strongly on albedo, row spacing, mounting height, shading and rear-side irradiance. At 33.4kg, mechanical handling and structure also require project-specific engineering.
Coverage note.
Canadian Solar’s current North American material lists a 12-year enhanced product warranty and 30-year linear power performance warranty; confirm the warranty statement applicable to the exact supplied module and market.
