According to a 2011 year-end article published by Technology Review, an MIT publication (www.technologyreview.com), the solar industry is facing a large oversupply of solar panels, fueled largely by manufacturers in China, which is home to four of the top five largest solar-panel manufacturers in the world. The article states that the average nominal (not adjusted for inflation) price of crystalline silicon solar panels fell from $1.90/watt to $1.35/watt from January to November 2011, according to GTM Research.
In addition, the world's solar capacity continues to grow quickly. GTM Research estimates that 20,563 megawatts of solar power were installed globally in 2011--13,553 megawatts in Europe, 2,083 in North America, 3,938 in Asia, 710 in Australia, and 279 megawatts in the rest of the world. That is 2,960 megawatts more than were installed in 2010, and brings the total global solar capacity to 59,152 megawatts.
