WASHINGTON, USA: The US solar energy industry installed a record 1,855 megawatts (MW) of photovoltaic (PV) capacity in 2011, more than doubling the previous annual record of 887 MW set in 2010, according to the latest US Solar Market Insight report.
The record amount of solar installations is enough to power more than 370,000 homes, and represents a 109 percent growth rate in 2011. It is the first time the US solar market has topped one gigawatt (1,000 MW) in a single year. In the fourth quarter of 2011 alone, the industry installed 755 MW, up 115 percent from Q4 2010, for a second consecutive record-breaking quarter. GTM Research and the Solar Energy Industries Association (SEIA) estimate the US solar market's total value surpassed $8.4 billion in 2011.
This unprecedented growth was spurred in part by declining installed solar photovoltaic (PV) system prices, which fell 20 percent last year on the back of lower component costs, improved installation efficiency, expanded financing options, and a shift toward larger systems nationwide. In addition, the anticipated expiration of the US government's 1603 Treasury Program, which ended Dec. 31, 2011, drove developers to commission projects before the end of the year.
The report also provides an update on the concentrating solar power (CSP) market. While no new concentrating solar thermal electric capacity was brought online in 2011, a total of 10 concentrating photovoltaic projects came online. The year also saw meaningful construction progress on a number of projects with some capacity expected to come online later in 2012 and a surge in 2013. Today, more than 1,000 MW of CSP are under construction, enough to power 200,000 homes.
As of year-end 2011, cumulative PV capacity in the US reached nearly 4,000 MW and cumulative CSP capacity topped 500 MW. Together this represents enough solar capacity to power nearly a million households.
"In 2011, the market demonstrated why the US is becoming a center of attention for global solar," said Shayle Kann, MD of GTM Research's solar practice. "It was the first year with meaningful volumes of large-scale PV installations; there were 28 individual PV projects over 10 megawatts in 2011, up from only two in 2009.
Further, the market continued to diversify nationally; eight states installed more than 50 megawatts of solar each last year, compared to just five in 2010. These are all indicators of a vibrant market."
The latest US Solar Market Insight report found 800 MW were installed in the commercial sector in 2011, led by the California and New Jersey markets, compared to 758 MW of utility PV and 297 MW of residential installations. Utility-scale project installations, primarily across states in the Southwest, nearly tripled 2010 totals. In the residential sector, California installed 114 MW, with New Jersey, Arizona, Hawaii, Pennsylvania and Colorado each contributing meaningfully to the residential total.
According to US Solar Market Insight, 2012 will be another strong year for the PV industry, with installations of more than 2,800 megawatts forecasted. Beyond 2012, the report forecasts installations to continue their ascendancy at a compound annual growth rate of 30 percent through 2016.
"The solar industry is the fastest growing industry in America for the second year in a row. What we are seeing in the US is that policies are working to open new markets and remove barriers for solar," said Rhone Resch, president and CEO of SEIA. "The industry is now poised for years of multi-gigawatt growth and the creation of tens of thousands of new jobs. But, we face a number of challenges that have the potential to slow this growth. That is why SEIA now coordinating the industry's federal and state policy initiatives to present a unified, cohesive voice for the solar industry."
A separate report on 2011 growth of US solar heating and cooling technology is expected midyear.
