I'm a bit surprised that China has produced too many panels. People keep talking about the coming eco-apocalypse from countries like India and China becoming more developed and needing more electricity, and not having the capacity to generate that cleanly.
Chinese mining has a lousy safety record, even for a dangerous industry. (15 people PER DAY dying just from volatile gases, in 2010) Anything that offloads electricity generation from dangerous mining for coal powered stations is a good thing for China. So I'm not sure why they're not just putting these solar panels on every roof.
