"Although we expect to post a nearly 60 percent increase in revenue in the first quarter of 2011 compared to 2010, we’ve revised our guidance for the quarter due to recent adverse conditions in the European solar market," said Richard Thompson, Chief Executive Officer of Power-One. "Based on current developments, we still anticipate European countries such as Italy and Germany will continue to support solar adoption to reduce reliance on non-renewable sources of power. Further, for the remainder of 2011 and 2012, we believe we are better positioned to handle similar regional anomalies due to our expanded product line and focus on developing new markets, including the United States, China and India."
