and levels of one-time costs, including restructuring charges; our ability to meet all the terms and conditions of our debt obligations; and our ability through technology improvements to reduce cost and improve the conversion efficiency of our
solar products. The risk factors identified in our filings with the Securities and Exchange Commission, including the Company&#146;s most recent Annual Report on Form 10-K and most recent Quarterly Report on Form 10-Q, could impact any
