Definition
Net electricity generated from solar energy in the year, in terawatt hours: utility-scale photovoltaic and solar thermal plants of 1 megawatt or more, plus the U.S. Energy Information Administration's estimate of small-scale photovoltaic systems such as rooftop panels.
United States and its states only, from 2014, the first year of EIA's small-scale estimates. The state total in electricity generation leaves small-scale solar out, so solar divided by that total overstates its share.
