This agreement positions Canadian Solaras one of the first crystalline silicon solar module manufacturers to offer comprehensive recycling services to its U.S. customers.

Under the terms of the agreement,SOLARCYCLE will serve as Canadian Solar's preferred recycling partner,while Canadian Solar will act as an original equipment manufacturer (OEM) partner to SOLARCYCLE,offering upfront recycling services.
