On CAPS, 98% of the 1,183 members who have rated ReneSola believe the stock will outperform the S&P 500 going forward. These bulls include Jonebone and meadornack.

Just last month , Jonebone tapped ReneSola's recent price weakness as an opportunity to pounce: "$15 by summer, going to be one of the leaders in the Chinese solar market. Perfect fundamentals as well as an awesome technical pullback, this is a no-brainer."

In fact, ReneSola currently sports a particularly paltry forward P/E of 4.8. That represents a clear discount to rivals such as MEMC (8.8), Trina Solar (6.7), and Yingli Green (7.9).

CAPS member meadornack expands on the outperform argument:

Everything looks good with ReneSola Ltd (SOL).

Revenue increased by 136% in 2010. Growth was driven by strong sales of the company's popular solar modules. For the full 2011 year, analysts project revenue will increase 11.3% to $1.3 billion, then another 4.1% to $1.4 billion, by 2012, as shipments and customer orders continue to increase.

Along with high growth outlook, SOL has an equally as bright earnings outlook. And to top it off, the stock has a low trailing price-to-earnings ratio (P/E) under 5.
