Hey are we all talking about solar heating panels (or vacuum tubes) or are we talking about photovoltaic? I'm under the impression that solar heating can pay for itself without subsidy, such as feed-in tariff, but numbers provided by different groups are inconsistent. One community I came across had solar vacuum tubes installed, expecting to get their money back in savings over about eight years, but because of the rise in energy costs they got their money back in six...
Photovoltaic I hear are not so economic were it not for the subsidy...
