I sincerely doubt the Namibian government is giving out thousands of dollars per household in solar subsidies, like the US does up until the end of this year. I doubt Pakistan does either, another country noted in the article where solar usage is expanding. If solar is a mature technology and an economic inevitability as contended in the article (I agree), there is a much weaker case for subsidizing it. In any case, most solar installation costs in the US seem to go to permits and expensive, inefficient contractors - endemic problems which affect all types of development and are probably only made worse by throwing free money at them.
