Many of the problems that forced solar company Solyndra to shutter operations threaten other businesses in the sun-power industry, with more upheaval likely in the coming months, analysts say. The bankruptcy last month of Fremont, Calif.-based Solyndra comes as solar manufacturing undergoes a major transition. Prices of solar panels have plummeted, causing a supply glut and slicing company revenues. Solyndra's collapse marked the third time in as many weeks that a solar company declared bankruptcy. Evergreen Solar Inc. of Massachusetts and SpectraWatt of New York also filed for protection.
