Tech Biz Roundup: Solar Stocks Slide, Nokia Executive Has Left The Building

Certain solar stocks sold off Friday due to at least two factors. Shares of First Solar (NASDAQ:FSLR) slid following a downgrade by Avian from Positive to Negative, due to claims that the junction boxes with the firm’s solar module installations are seeing reliability problems, even though the warranty on First Solar’s modules lasts for 20 years. Also, a negative New York Times article in regards to Chinese production appears to have caused shares of Guggenheim Solar (NYSE:TAN) and Trina Solar Limited (NYSE:TSL) to drop, but peer solar firm Suntech Power Holdings Co. (NYSE:STP) rebounded slightly.
