Another bull thesis argument is the Environmental Protection Agency's actions are benefiting solar. There's little doubt EPA administrator Gina McCarthy is doing everything in her power to destroy the coal industry. It's natural to conclude solar should be a enormous winner with the demise of coal.
Unfortunately, stopping new coal plants and forcing cuts in existing coal produced power is offset by the natural gas boom. Natural gas prices have fallen as production expanded faster than consumption. Solar needs to make significant cost per watt breakthroughs to become competitive.
Once solar is able to cross the line of cost competitiveness, the remaining solar stocks will have a sunny future. I don't think that day is far away, but wait until they bury the zombie solar stocks before investing.
