Solar PV


The U.S. Solar industry achieved another record year in 2014, growing by 34% over 2013 to install nearly 7,000 megawatts (MW) of solar electric capacity. Within the photovoltaic (PV) sector, over 6,200 MW of capacity was installed, led by the residential and utility segments, which grew by 51% and 38%, respectively. The concentrating solar power segment enjoyed its largest year ever with 767 MW of capacity installed. Together, the solar industry istalled 32% of all new electricity generating capacity in the U.S. – second only to natural gas. This growth is expected to continue, with an additional 20,000 MW of solar capacity projected over the next two years.
