Just when I think I am doing something good for the environment, I hear that my so-called "green" strategy is just as harmful as not doing anything at all (in the past for me - the prius).

Now I read that the production of solar panels produces large amounts of lethal hazardous wastes (silicon tetrachloride) where most panels are manufactured - China. I am currently about halfway into the process of putting solar panels on my home, and it worries me that my project has resulted in more pollution.

Does anyone know what I should look for when buying solar panels so I can try to buy ones that are produced ecologically? Any replacement for this kind of technology?

Dear teddyz,

Unfortunately, it is going to be a case of pick your poison. You can go with silicon based technologies and know that they use silicon tetrachloride. You can go with CIGS technology understand there will hazardous waste due to the selenium content. If you are concerned about the pollution associated with products you purchase, buy American or European. In my opinion unlike China, there is a long established environmental ethic in these regions and regulations to back it up. Of course, you'll pay more. I haven't seen anyone touting a "clean" manufacturing process for solar panels.
