Graph Porn: Germany’s Solar PV Price Drop

 
Someone recently passed along these great graphs from a German website (you can see an English translation of the webpage they came from here). The overall message: solar PV prices in Germany have dropped considerably in the past few years (as installation has boomed), and the prices are pretty darn low these days.

More specifically, note that the graphs are not for the same time period — they are sequential. So, basically, the price just dropped and dropped and dropped and dropped. (The same thing is happening in the US, just not as fast, since installation isn’t happening as fast and because of some other factors, like balance of system costs and regulations.)

Take a look at the graphs below and let me know if anything else comes to mind for you (note: prices are per kWp for plants up to 100 kWp solar power plants):

Amazing, isn’t it?
