Contract disputes among solar companies are common occurrences. LDK Solar ( LDK) filed a lawsuit against Canadian Solar ( CSIQ), also at the beginning of September, to demand compensation from Canadian Solar for breach of a "take-or-pay supply agreement signed by the two companies and the illegal termination of the agreement."

LDK claims that Canadian Solar failed to adhere to its purchase obligations and ceased making payments. --Written by Eric Rosenbaum in New York. >To contact the writer of this article, click here: NAME.
