Solar accounted for 58% of all new electricity-generating capacity added to the US grid through the third quarter of 2025, with more than 30 GW installed. 2024 ATB data for utility-scale solar photovoltaics (PV) are shown above, with a base year of 2022. The Base Year estimates rely on modeled capital expenditures (CAPEX) and operation and maintenance (O&M) cost estimates benchmarked with industry and historical data. Following a low second quarter, the industry is ramping up as the end of. 2024 values are estimated. Global annual investment in solar PV and other generation technologies, 2021-2024 - Chart and data by the International Energy Agency. This surge in investment reflects the rapid growth and increasing importance of solar. Each quarter, the National Renewable Energy Laboratory conducts the Quarterly Solar Industry Update, a presentation of technical trends within the solar industry. Each presentation focuses on global and U. supply and demand, module and system price, investment trends and business models, and. NLR analyzes the total costs associated with installing photovoltaic (PV) systems for residential rooftop, commercial rooftop, and utility-scale ground-mount systems. NLR's PV cost benchmarking work uses a bottom-up.
