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
By J. Matthew Roney
The world installed 31,100 megawatts of solar photovoltaics (PV) in 2012—an all-time annual high that pushed global PV capacity above 100,000 megawatts. There is now enough PV operating to meet the household electricity
needs of nearly 70 million people at the European level of use. While
PV production has become increasingly concentrated in one country—China—the
number of countries installing PV is growing rapidly. In 2006, only a
handful of countries could boast solar capacity of 100 megawatts or
more. Now 30 countries are on that list, which the International Energy
Agency (IEA) projects will more than double by 2018.
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.)
Today roughly 60 percent of PV is manufactured in China.
A decade ago, China produced almost no PV. But in a kind of gold rush
spurred by easy bank loans and government tax incentives and subsidies,
China hurtled past PV technology pioneers the United States (in 2006)
and Japan (in 2008).
The
flood of new companies entering the Chinese PV industry over the last
several years created a massive oversupply of panels at the global level
and accelerated the already fast-paced drop in world PV prices. Many
firms in other countries went bankrupt or shut down factories, and now
even some Chinese companies are folding as the industry consolidates.
Worldwide, PV production in 2012 declined 2 percent from 2011, the first
annual drop on record. But this contraction will be short-lived as
demand continues to rise. Solar power installations are growing more than 40 percent annually, and falling PV prices are making solar power more affordable.
China,
where PV had previously been too expensive to be widely adopted, may
soon lead the world in generating electricity from PV. Each year since
2006 China has at least doubled the amount of new PV installed
nationwide. After installing 5,000 megawatts in 2012, China is number
three in the world with 8,300 megawatts of total PV capacity, trailing
only Germany and Italy. And in July 2013, the government officially set a new national PV capacity goal of 35,000 megawatts by 2015.
Depending
on China’s 2013 final tally, Japan could well install the most PV this
year, perhaps more than 9,000 megawatts. This would give Japan some
16,000 megawatts of solar capacity—over halfway to its official 2020
target of 28,000 megawatts. Historically, Japan has been the world’s
leading market for residential rooftop PV; in 2011, some 85 percent of
PV capacity added there was residential. After the March 2011 Fukushima
nuclear disaster, though, the government introduced a generous
incentive encouraging larger projects, thus spurring huge investment in
utility-scale PV capacity.
The
other big Asian solar story comes from India, a country of 1.2 billion
people where an estimated 290 million still lack electricity. According
to the solar energy
consultancy Bridge to India, the country had 1,700 megawatts of PV
installed by May 2013, with 80 percent of it in the sun-drenched
northwestern states of Gujarat and Rajasthan. Bridge to India projects
that figure will jump to 12,800 megawatts by 2016. India’s National Solar Mission calls for 22,000 megawatts of solar power
nationwide by 2022, including 2,000 megawatts of off-grid PV. Going
solar is becoming increasingly attractive in India due to notoriously
frequent blackouts and climbing grid power prices—not to mention that
solar is now cheaper than diesel for electricity.
Even
though Asia’s PV installations are soaring, it will be some years
before it can unseat the European Union (EU) in regional PV dominance.
The EU boasts 68 percent of world PV capacity. In 2012, for the second
year running, the EU added more PV than it did any other
electricity-generating technology. EU countries now annually installing
hundreds or thousands of megawatts include Austria, Belgium, Bulgaria, Denmark, Germany, France, Greece, Italy, and the United Kingdom.
Germany
remains the world’s solar capital, home to nearly one third of global
PV capacity. For the third straight year, Germany added more than 7,000
megawatts of PV in 2012, reaching 32,000 megawatts. Accounting for some 5
percent of national power use, the electricity flowing from Germany’s solar panels in 2012 was enough to supply more than 8 million homes.
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.)
The
main policy driver that has allowed Germany and Italy to amass their
world-leading solar capacity is the feed-in tariff (FIT), which
guarantees renewable energy
generators a long-term purchase price for the electricity they supply
to the grid. As these markets mature and solar system costs decline, FIT
incentives are being reduced. But worldwide more than 70 countries—the
majority of them now in the developing world—use some form of FIT.
Until recently, the United States lagged badly in PV capacity despite its abundant solar resources. (Nearly every state gets more sun
than Germany does.) But annual U.S. solar installations doubled in
2011, and nearly did so again in 2012, when 3,300 megawatts of PV came
online. As of mid-2013, U.S. PV capacity had passed the 10,000 megawatt
mark.
Renewable
portfolio standards (RPS)—laws now in 29 states typically requiring
that renewables account for a specified share of the electricity that
utilities sell—have historically driven U.S. PV development. In California, the U.S. solar leader, utilities must get one third of their electricity from renewable sources by 2020. Federal tax credits
and cash grants are also PV catalysts, as are the increasingly popular
arrangements allowing homeowners to lease a system from solar developers
like Sunrun and SolarCity rather than footing the entire upfront cost.
More than half of U.S. residential systems are now leased.
Another solar-rich country finally starting to seriously ramp up its PV capacity is Australia.
Residential rooftops host the majority of its 2,400 megawatts, 42
percent of which were installed in 2012. In the state of South
Australia, one in five homes is solar-powered.
Large
PV projects are announced seemingly every week in countries with little
or no previous solar capacity. For example, in mid-2013 construction
finished on an 84-megawatt project in Thailand. The 96-megawatt Jasper
Solar Project, financed in part by Google, is under way in South Africa. And two projects of over 100 megawatts gained local approval in Chile.
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.
Even
as PV deployment moves toward larger applications, it is well worth
noting the virtues of smaller-scale solar, especially for developing
countries. In rural areas with no grid access, installing solar PV at
the home level is often cheaper than building a central power plant and
electric grid. Bangladesh,
working for over a decade with the World Bank, had installed 1.4
million rural solar home systems as of mid-2012, for example. Peru
recently announced that the first phase of its national home
electrification program will equip a half-million off-grid homes with
PV.
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.
