RenewEconomy has a look at continuing drops in the cost of producing solar panels - Graph of the Day: Solar module costs down 20% in 2013.
Two of the key metrics that will be watched closely in the global solar industry reporting season that has just commenced are the price of panels sold, and the cost of manufacture. The difference is what the industry calls the margin. ...
REC Solar, one of the leading European solar companies produced these two graph in its results last week.
The first is the price of solar modules, which shows a rebound. The second is the crucial one for the future of the industry, and its ability to undercut fossil fuels over the long term, because it shows that the cost of manufacture of a solar module will fall around 20 per cent over the year – despite the 60-80 per cent falls achieved over the previous three to four years. The same story is expected to be repeated among many other manufacturers.
