SunPower stock dropped 3.67 percent after guiding estimates lower for next year, but CEO and President Tom Werner said Thursday that he remains optimistic about the company's future.
"It's all about the holdco," he said. "And then if you look at the big picture, we said we're going to triple capacity in the next five years. We're doing great in China. The fastest growing market in the world. So I think I'd say we'll be back."
The second-largest maker of solar panels in the United States issued a lower-than-expected 2015 earnings forecast of $1.10 to $1.50 per share. SunPower stock closed at $28.08, down 5.8 percent year to date.
On CNBC's "Fast Money," Werner touted the company's increasing ability to give energy consumers a choice.
