For the first time, renewable energy products contributed the majority of the company’s revenue, at 54% of total sales in the quarter, versus 13% in the first quarter of 2009. Power-One’s power products generated revenue of $70 million in the first quarter 2010 versus $85 million in the same period of 2009, with the majority of the decline due to component shortages experienced in the industry.
