Wikipedia on the price of solar panels. The last sentence shows the "Moore's law" type trend which I hope will continue.
Average pricing information divides in three pricing categories: those buying small quantities (modules of all sizes in the kilowatt range annually), mid-range buyers (typically up to 10 MWp<http://en.wikipedia.org/wiki/MWp>annually), and large quantity buyers (self-explanatory—and with access to the lowest prices). Over the long term there is clearly a systematic reduction in the price of cells and modules. For example in 2012 it was estimated that the quantity cost per watt was about $0.60, which was 250 times lower than the cost in 1970 of $150.[21]<http://en.wikipedia.org/wiki/Solar_panels#cite_note-21> [22] <http://en.wikipedia.org/wiki/Solar_panels#cite_note-22> Some sunny countries have already reached "grid parity" where solar power is as cheap as mains power. If the downward price trend continues solar will soon become the best option for everything except transport (assuming it can be put into a grid and sent where needed, that is, otherwise it will be the best option while the sun is shining or some has been stored). -- You received this message because you are subscribed to the Google Groups "Everything List" group.
