During the quarter, the Hebei, China-based company more than doubled its power production to 49.2 mega watt (MW) and shipments tripled to 51.4 MW.

The company also maintained its 2008 revenue outlook of $1.03 billion to $1.14 billion. Analysts were expecting $1 billion.

JA Solar also backed its total production output of at least 340 MW for 2008, with a total annual production capacity of no less than 500 MW.
