By the end of 2009, the United States had installed 1,164 cumulative megawatts of solar PV. In less than five years' time, that total had skyrocketed to nearly 15,000 megawatts, according to GTM Research and the Solar Energy Industries Association's U.S. Solar Market Insight report.

The short animation below shows the adoption of solar PV across the nation's top 30 solar states. In the first quarter of 2011, California crossed the 1,000 cumulative megawatt mark, and in Q4 2013, the state installed 1,200 megawatts of PV in just three months.

Other states to keep your eye on in the animation are Arizona, New Jersey, Massachusetts and North Carolina.
