Decreasing suppliers and better manufacturing technology for First Solar, Inc. (NASDAQ:FSLR) mean higher revenue and higher profits. Their share price of $45 is nowhere near their 2008 share price in the $200's, so could we be looking at a comeback? Panel costs have gone down and SolarCity alone plans on installing 270 MW this year, up from 250 expected. The entire United States is expecting 5.3 gigawatts to be installed compared to 3.3 from last year. That's almost 70% growth. The future of electricity If the growth that SolarCity Corp (NASDAQ:SCTY) and First Solar, Inc. (NASDAQ:FSLR) are experiencing continues, their 2.7 billion and 3.9 billion market caps will be pocket change in a few decades. But will the government realize the potential we have for complete energy independence using only renewable energy sources and continue subsidies? If things continue to pan out for these forward thinking companies, investors could be sitting on a nice profit.
