Enphase Energy will become the first solar company to go public on the U.S. market since the fall of 2010, when its stock begins trading on the Nasdaq on Friday under the symbol ENPH.

The California company said it's sold nearly 9 million shares at $6 a piece, raising about $54 million. That was at the low end of the $6-$7 price range that it announced only earlier this week, and Enphase initially set its share price at between $10 and $12 per share, aiming to sell 7.3 million shares.
