My first thought when reading this was that it was really confusing cause and effect and (deliberately?) failing to cover the alternatives to solar. So I was pleased to see the currently top rated comment here started out with:"The reason is because grid power is more expensive in Germany: $0.30/kWh compared to $0.10/kWh on average in the US. Therefore potential customers are easier to convince to use solar in Germany." Many of the issues highlighted in the US simply relate to where the US is in the curve of adoption. If Solar was more competitive with the regular grid then a) There would be more demand = lowered customer acquisition costs = lowered installation costs (vols and skills) = reduced red tape based on political clout from industry and consumers. So everything outlined in this article seems more about symptoms than causes. What we do about that can either be government regulation driven or market driven but either way it feels like a pretty big missing piece from the original article.

Good points, but on the flipside, German solar is probably roughly a third as productive as sunny American states could be... so when you factor in the added output per equivalent installation, the 3x grid cost should be roughly mitigated. However, the trouble is the costs are not primarily correlated with size of installation and the cost of the panels themselves are no longer the primary cost driver. This means tertiary costs like installation and regulation, which do not necessarily scale with system size, are an important and complex piece. edit: it's not 3x but still as high as 2.5x in some places: http://www.nrel.gov/gis/images/us_germany_spain/pv_map_us_germany_spain.jpg http://www.nrel.gov/gis/images/us_germany_spain/pv_map_us_ge... and more if you compare to northern Germany. Anyway some parts of the US have significantly higher power costs than others (not surprisingly these are generally good solar sales markets)
