Solar power's ‘a decade-long story’: Pro

Solar energy has a red-hot future, Josh Brown of Ritholtz Wealth Management said Monday after a strong finish for First Solar stock.

"I'm long, and I'm not selling," he said, adding that he also holds a position in SunPower. "But ... the name that makes more sense than chasing First Solar here is TAN. That's an [exchange-traded fund] that owns the 22-most-levered-to-solar companies in the world. It's global. It's got Europe. It's got China and U.S."

On CNBC's "Fast Money," Brown said that the Guggenheim Solar ETF offered opportunity while de-emphasizing risk.

"That's now making all-time highs from when it launched," he said. "That's the one because you minimize single-stock risk, but you still play the theme. And again, this is for investors. If you want to trade the names, you certainly could."

Brown said that the solar power had industrial growth factors behind it.

"Most people in America still, when they think of solar stocks, they think about, like, their neighbors' roofs," he said. "That is not what's happening here. This is now an industrial play. All of those stocks I just referenced are building power plants, and they're getting massive engineering contracts. This is not about selling shingles to your neighbor. And I'm talking globally."

Brown noted that Berkshire Hathaway's CEO was a believer.

"Warren Buffett is building the largest solar plant in the world right now out in the desert here in the U.S.," he said, adding that Google is also augmenting its solar power capacity.

"That's the opportunity," he added. "And I don't think it's a short-term trade. I think it's a decade-long story."

Tim Seymour of said he expected the space to perform better.

"You're actually seeing overproduction come down," he said, adding that Chinese demand was up.

Seymour held a long position in Trina.

StockMonster Guy Adami was less sanguine.

"A couple of things strike me," he said. "Extraordinarily volatile. We're trading up against levels we last saw a few years ago."
