The global solar market is driving solar stocks higher this year as the U.S., Japan, and China kick into high gear. The U.S. is expected to install 4.4 GW of solar this year, Japan may put up 7 GW, and China is expecting annual installations of about 10 GW. 

For investors, this creates a great opportunity, particularly for companies with industry-leading positions. SunPower (SPWR -1.02%) makes the most efficient panels in the industry and has exposure to each of these markets, Canadian Solar (CSIQ 0.60%) was one of the first Chinese manufacturers in Japan, and SolarCity (SCTY.DL) is dominating U.S. residential solar.
