The United States has more than 2,500 utility-scale (larger than one megawatt) solar photovoltaic electricity generating facilities, most of which are relatively small and collectively account for just 2.5 percent of utility-scale electric generating capacity and 1.7% of annual electricity generation, based on EIA data through November 2018.

• North Carolina has 433 utility-scale solar photovoltaic facilities with capacities no greater than 5 megawatts, the most of any state, and accounting for nearly a quarter of all utility-scale solar photovoltaic facilities in the country between 1  and 5 megawatts.
• Growth in small utility-scale facilities is expected to continue through 2020, with most of the 216 solar photovoltaic facilities expected to come online by the end of that year having capacities under five megawatts, according to the EIA’s Preliminary Monthly Electric Generator Inventory for October 2018.
• The agency also estimates that small-scale solar photovoltaic capacity is about 40 percent of the total solar capacity connected to the grid as of November 2018.
