While the tremendous growth potential of the solar power industry has many investors greedily eyeing future profits, there's certainly an eco-friendly angle to solar investment. Given this impulse to make money and save the planet, it would be sadly ironic for investors to ignore the environmental impact of the solar supply chain.
The energy generated by solar power systems may be clean and green, but it's important to watch what goes on behind the scenes. As a Washington Post story brought to light back in 2008, some Chinese firms have simply dumped their industrial waste, rather than recycle it. Even companies with meticulous recycling programs may face future environmental setbacks, purely based on the materials used.
Polysilicon production's potential pitfalls
Like any chemical plant, however, LDK's facilities handle volatile and hazardous materials. There have been multiple rumored explosions at LDK's plant, which haven't been officially recognized and which I have no way of verifying. (Anyone out there know someone who lives in Xinyu? Please have them drop me a line.) Regardless of the veracity of these reports -- dutifully forwarded to me by the company's vocal detractors -- I would note that there's at least a non-trivial risk of an explosion taking a toll on both human health and LDK's bottom line.
If this possibility sounds so improbable as to hardly be worth considering, talk to a BP
The cadmium question
The risk of a cadmium-linked downfall for this leading solar firm is probably quite low, but First Solar does give the matter of "increasingly stringent governmental regulation" a fair amount of space in its 10-K. I think it's worth familiarizing yourself with the situation if you're a shareholder. A good place to stay up to date on the EU situation is the Directive Decoder blog.
A standout among panel players
While there are hidden environmental risks among the solar stocks, there are unheralded leaders in this area as well. Yingli Green Energy
In 2009, Yingli was the first Chinese firm to join PV Cycle, which promotes voluntary take-back recycling programs for solar modules at the end of their lives. This is akin to what Cisco
Another accolade that caught my eye last week was Yingli's inclusion among the most-recommended PV brands by the U.K.'s Ethical Consumer magazine. One factor influencing the report was Yingli's SA8000 certification, indicating adherence to an international standard for working conditions. Yingli was the first China-based solar company to receive this certification.
Is it a coincidence that Yingli is also one of the most competitive solar suppliers today? Maybe, but I tend to think that excellence tends to permeate an organization and transcend categories such as financial and organizational performance.
