When First Solar (FSLR 2.85%) reported third-quarter earnings per share of $1.94 it shocked investors. The increased profits were driven by an $0.08 reduction in cost per watt, 860 MW of project signings, and a plan to make panels that are as much as 17% efficient. 

First Solar is leveraging its utility scale solar prowess to generate a 28.8% gross margin, which far exceeds SunPower (SPWR) and Canadian Solar (CSIQ -0.98%), two solar manufacturers who have built significant power plant businesses of their own.
