How much solar power did the US solar industry install in 2024?In 2024, the US solar industry installed nearly 50 gigawatts direct current (GWdc) of capacity, a 21% increase from 2023. This was the second consecutive year of record-breaking capacity. Solar accounted for 66% of all new electricity-generating capacity added to the US grid in 2024, as the industry continued experiencing record growth.
What is the DC capacity factor of a solar PV facility?This approach applies to not just capacity values but also to costs and operation characteristics. For example, the AC capacity factor for solar PV facilities operating in 2017 was 27%. If this value were estimated using DC capacity, the DC capacity factor would be about 22%.
What is the US large-scale solar photovoltaic database?The U.S. Large-Scale Solar Photovoltaic Database provides the locations and array boundaries of U.S. photovoltaic facilities, with capacity of 1 megawatt or more.
How much solar capacity will the US have?Our annual Year in review report includes a 10-year outlook for every segment. We expect cumulative US solar capacity to more than triple from 236 GWdc installed at year-end 2024, to 739 GWdc installed by 2035, with average annual capacity additions of more than 45 GWdc.
How much does solar PV cost per watt?If this value were estimated using DC capacity, the DC capacity factor would be about 22%. Similarly, the average capital costs for utility-scale solar PV facilities installed in 2015 were $2.91 per watt in terms of AC capacity and about $2.33 per watt in terms of the DC capacity of the PV modules.
What is the average solar inverter loading ratio?Inverter loading ratios are higher for larger solar power plants. At the end of 2016, smaller plants—those one megawatt (MW) or less in size—had an average ILR of 1.17, while larger plants—those ranging from 50 MW to 100 MW—had an ILR of 1.30. As solar plants have gotten larger, inverter loading ratios have increas
