UPDATE Oct 5: The infographic has been updated and relaoded.
UPDATE Sept 19: Took some digging, but I just found that the average all-in residential solar PV system cost was down to $3.74/watt in Q2 2014. With the average system size being 5 kW, that makes the average cost $18,700, much lower than the $55,000 figure that comes from the EIA and is likely very out of date.
I have steered away from sharing crappy infographics (there are a lot of them out there), but a great infographic is, well,… great. I love this infographic below about various solar energy facts and the growth of residential solar energy. It is clearly organized, shares great information, is easy to read, guides the eye well, and is pretty. [Edit: However, note that some of that stats, regarding the price and efficiency of an average residential solar energy system, are out of date and likely way off the mark. See comments under the article for some perspective. The source of that data is here.]
Check out the infographic, share it, and check out the links below the infographic for more fun solar energy facts:
