* Solar photovoltaic capacity factor is based on the plant’s electricity generation as a percentage of its summer capacity value for plants with a full-year of operation, as expressed in terms of alternating current (AC) power.
This statistic depicts the solar photovoltaic capacity factors in the United States between 2014 and 2017, broken down by select state. In that period, Arizona had a solar PV capacity factor of about 29.1 percent.
