I agree with you that if you only get an EROI of 6.5, that's in itself just barely worth it. But to be fair, things are changing really fast. The United States has just added import taxes on Chinese solar panels, to prop up the US solar industry, from 30 to 250 percent depending on the manufacturer. This seems to me a really obvious sign that solar cells are getting a _lot_ cheaper. This might or might not change the energy question, but the economic viability of solar cells is getting better. Can't find the source on this, but I read somewhere that the newest Chinese solar panels are clearly economically viable even without subsidies. http://www.bloomberg.com/news/2012-05-17/u-s-solar-tariffs-on-chinese-cells-may-boost-prices.html http://www.bloomberg.com/news/2012-05-17/u-s-solar-tariffs-o... http://www.bbc.co.uk/news/business-18112983 http://www.bbc.co.uk/news/business-18112983
