LONGi Solar continues to be the only AAA-Rated module supplier, largely because the company’s finances remain in a different league to all other companies shipping GW-plus product annually today. This is coming in part from gross/operating margins – even through 2020 – well above others, but almost regardless of the financial ratio/metric compared, LONGi Solar is either best-in-class or in the upper quartile.

The latest release of the PV-Tech PV ModuleTech Bankability Ratings report shows eight module suppliers with A-Grade ratings, and LONGi Solar again the only AAA-Rated company.
