Energy is one of the most important topics in the world economy at the moment, particularly from a long-term standpoint. As renewables continue to gain greater support from both sides of the political aisle in the U.S. (and in many developed and developing nations abroad), there's inevitably a push toward investment opportunities in this space. Publicly-traded solar energy companies are in particular focus, and names like First Solar, Inc. (NASDAQ:FSLR), SunPower Corporation (NASDAQ:SPWR) and GT Advanced Technologies Inc (NASDAQ:GTAT) have been brought to the center of Mr. Market's attention.
Speaking of First Solar specifically, it is important to mention that in its recent acquisition of the Japan-based TetraSun, there exists a key opportunity for expansion that couldn't exist elsewhere. In Japan in particular, limited land availability reduces the space that solar providers have for PV plants, and TetraSun, which specializes in rooftop systems, should be a good way for First Solar, Inc. (NASDAQ:FSLR) to expand vertically, rather than horizontally--literally speaking. See Insider Monkey for more about solar stocks.
