BANGALORE, May 12 (Reuters) - GT Solar International Inc (SOLR.O) on Tuesday reported a 59 percent drop in quarterly profit, and the solar equipment maker also forecast full-year profit below market view, sending its shares down as much as 15 percent.

The company's shares fell to a low of $6.05 in trading after the bell, after having closed at $7.22 in regular trade Tuesday.

"It was basically a top-line driven miss," Raymond James analyst Pavel Molchanov told Reuters, adding that there was a significant difference in estimates and reported revenue.
