Demand for solar power is expected to grow by an average of 47 gigawatts per year from 2014 through 2020. The lion''s share of that—39 GW a year—is attributable to six markets: the U.S., Europe, China, Japan, India and Brazil. This same group saw demand grow by 36 GW in 2013, while globally, demand grew by 40 GW.
