Evergreen Solar Inc (ESLR) shares were down 9% on Monday after their primary supplier of raw materials pulled out of a contract. Evergreen Solar relies on granular silicon to make cells for solar panels. This silicon was supplied in part by MEMC Electronic Materials Inc. (WFR). MEMC previously agreed to supply Evergreen with 90 metric tons of granular silicon, but in January said it did not intend to ship most of the remaining balance of 53 metric tons. Evergreen plans to used its own crush chunks of silicon, but said it has not fully tested the process at commercial scale. [ more ]
