I agree there is a lot of positive news on solar.  For me the question is whether, for a given pot of money, government should adopt the role of a venture capitalist or instead, raise or extend the feed-in tariff.  In the case of the latter it is up to innovators and their traditional funders to place their bets based on prospects for technological success.

Should government have some role?  Absolutely, because it is redressing a system where pollution is not sufficiently taxed.  But best to raise the payoff and let the pros make investments.
