Zacks analyst Jon Kolb discussed a few solar names in an interview released this morning. 

On ReneSola (SOL): 

"Through its short history, ReneSola regularly adapted to changing market dynamics. The company is aggressively ramping up its polysilicon and solar wafer production capacities.

Going forward, increased captive generation of polysilicon will improve its cost structure and enable wafer capacity expansions. Globally, rising solar wafer sales, along with escalating crude and long-term supply agreements, should collectively generate significant earnings growth.

That said, SOL is a play on growth in the solar industry. ReneSola’s customers include global manufacturers of solar cells and modules, such as JA Solar (Nasdaq: JASO), Motech Industries, Solarfun Power (Nasdaq: SOLF), Suntech Power (STP) & Topco Technologies. "

The stock has moved significantly higher in the past hour and is currently up about 5%
