World solar power climbed above 100,000 MW in 2012

We write on solar power’s fast growth around the world nearly every day. There are a lot of people measuring solar power capacity and its rapid growth, but with it being such an awesomely distributed technology, and with it growing so fast, that’s pretty difficult. As such, there are different estimates of when the world will or did hit 100,000 MW of solar power capacity. The International Energy Agency thinks it’s happening sometime this year. As you can see in the repost below from the Earth Policy Institute, others think we passed that marker in 2012. Read on for the more optimistic take from the always excellent Earth Policy Institute, via sister site Sustainablog:

World Solar Power Topped 100,000 Megawatts in 2012

PV semiconductor materials convert the sun’s rays directly into clean, carbon-free electricity. Traditional solar cells—made of crystalline silicon—are combined into flat panels or “modules.” While residential rooftop systems are measured in kilowatts, large ground-mounted systems can reach thousands of megawatts of capacity. (One megawatt equals 1,000 kilowatts.)
World Annual Solar Photovoltaics Production, 1985-2012
After adding a world-record 9,400 megawatts of new PV to the grid in 2011, Italy connected 3,400 megawatts in 2012 to keep its second-place spot in installed PV, with 16,300 megawatts total. Italy got 5.6 percent of its electricity from PV in 2012. (See data.)

These large projects illustrate another global PV trend: the rise of the mega-project. Only a few years ago, the 10 largest solar farms were between 30 and 60 megawatts. Now PV parks of 100 megawatts or more are becoming commonplace. Arizona’s Agua Caliente PV project became the world’s largest at 250 megawatts when its fourth phase finished construction in 2012. (It will eventually be 290 megawatts.) Developers have announced a 475-megawatt PV farm in Nagasaki, Japan, due in 2016. Several projects between 500 and 3,000 megawatts are under development in California.
Analysts expect a new PV installation record of 35,000 megawatts in 2013. Even with the possibility that Europe’s annual installations will fall below 10,000 megawatts over the next few years, China, Japan, and the United States, along with the growing number of “newcomer” PV countries, will more than pick up the slack. The IEA estimates, perhaps conservatively, that world PV capacity will more than triple by 2018 to 308,000 megawatts—at peak power, the generating equivalent of 300 large nuclear plants.
